Cable Internet Tips and Tricks

Different Technique about Bandwidth Tests

Reason about bad Bandwidth Results

There are many reasons to change the value of bandwidth tests such as

  • Signal interference

  • User location

  • Downloading site status

  • Viruses

Network Bandwidth Test 

If you have a network in your home or office and sharing your internet connection then first you should use bandwidth meter test to check your local network bandwidth performance. Because network bandwidth speed test applications are used to point out the problem and help to deploy network monitoring system to improve your bandwidth management. Your bandwidth speed can affect your business performance, especially if you have a business Web site you maintain on your home network.

If your are using wireless cable internet connection that result will different with regular cable internet connection. But the same disturbances affect wireless bandwidth speed tests as regular cable internet.

File size and location of file

user Time and location.

Application usage

Heavy traffic through connection.

 

How do you find Best & speedy Cable Internet in your city

Many internet cable provider normally offer free connection for the first few month or very cheap service in start. Some internet providers offer 2 month free internet in start if you pay payments for next 6 month.
There are many DSL/Cable Internet web sites where you can search for best and cheap internet connection in your area. Usually the cheapest high speed cable Internet rate is of $15.00 a month, but this is not a standard rate , We have seen cheap cable Internet at $6.95 a month, but that's usually only for the first few months. But you can cheap more if  you're getting value-added services: free anti-virus protection, free installation, etc.

Here are some advice for check connection:

  • Avoid anything that sending you bulk e-mail with the words free cable Internet and you can use it any ware.

  • Don't trust offers of unlimited free cable Internet.

  • Some internet provider offers you free trial for some period but ask for your credit card, and then automatically charge you after the trial period has expired.

  • Beware of offers for a free cable modem or other equipment.

Cable Internet comparison with other internet provider

Faster Than Speeding Dial-Up (or DSL)

Normally a high speed cable Internet is better than a dial-up and some time DSL connection. A cable internet connection load web pages three times faster than a dial-up. Cable Internet's maximum speed is 2Mbps but this is not a standard , it depends upon you internet connection provider ,connection type like many option (128Kbs,256Kbs,1Mbps or more), your home distance from main router. Another main reason if you are using dedicated connection type or sharing connection type that effect speed. In dedicated connection you can use static IP address. You will probably be limited in your choice of cable Internet service by where you live, no other provider there. Some cable internet connection provider use their cable for both purpose like cable television and internet also. High speed cable Internet may have less downtime because there are no busy signals with cable Internet access, and that is why more reliable.

  • Your choice of a cable Internet service will also depend on factors such as:

  • what level of service you want, e.g. dedicated connection type or sharing connection type, what kind of security you need in internet connection e.g. if you are a normal user or you are running secure business like a finance company then your choice must be different to choose connection.

  • Whether you just use the Internet for e-mail or whether use VoIP or do broadcasting/streaming audio.

Easy ways to install cable Modem Drivers

How to install and troubleshoot cable modem? 

Installing a cable modem is a very easy with compare to dial-up modem or DSL modem but here does not even require you to open the case of your.

  1. First thing you will determine if you are connecting your cable modem to your computer using USB cable or CAT 5 cable. But no difference connecting via USB or CAT 5 cable will do the same thing, however, connecting via USB will consume system resources that using a CAT 5 cable will not.

  2. First one end cable you plug in your cable modem to the wall outlet cable and the other end via either USB cable or CAT 5 cable. If using a USB cable simply plug the USB cable into a vacant USB port on your computer.

  3. If you connect your cable modem to your computer via a CAT 5 cable, then there is no need to do any thing, you are now ready to use your cable modem and browse the Internet. If you are connecting your cable modem via a USB cable, then you will need to install USB driver onto your system

  4. If you run into problems disconnect all cables from your modem and restart your system and plug all cable again.

 

Guidance about Cable Modem Routers

Choosing a Router 

Your cable carrier and/or ISP probably provide you with a cable modem router to allow them ease of cable modem router setup and to make sure that all the equipment works together. That said, you can buy your own modem router, just as you can buy your own approved cable modem. In many cases you might opt for an all-in-one broadband cable modem router that combines the modem with the router.

If you want control over whether you can have VPN access and more advanced security features, or additional bells and whistles—especially if you're a DIY techie—buying your own modem router is for you, and many companies, such as Linksys and US Robotics, provide excellent technical support. However, in the event of router problems, it might provide peace of mind to deal with a cable Internet technician who knows your equipment.

Bluetooth and Wireless Cable Modem Routers


Most every wireless cable modem router you encounter is 802.11b-compatible, in other words, WiFi-compatible. Bluetooth technology offers its own modem router designed to be compatible with the Bluetooth PC Card and USB Adapter, also with cable modems. The Bluetooth Access Point and Router is an ideal modem router for those who want Bluetooth devices. The drawback is that Bluetooth is not compatible with the wireless standard, 802.11b. That's something to consider in your cable modem router setup. Bluetooth is a cable replacement system with not as much power as WiFi, so your cable Internet might not have the speed you desire. Learn about cable modem routers at ispbuyingguide.com.

Problems with Wireless Routers 

Wireless connections are iffy, and cable modem routers are only one of the reasons your wireless connection disappears. One thing to note about your wireless cable modem routers: If your cable internet connection goes out for even fifteen seconds, say if the cat knocks out a plug somewhere, your cable modem router won't be able to talk to your modem and computer. You can fix the problem by rebooting your computer, a step that assigns a new IP address. So in your cable modem router setup, make sure your cable modem is in a protected spot where pets, kids, and you can't interfere with it.

Sometimes the problem may not be with the modem router, but may actually be with the adapter. If you've moved your wireless adapter, you may need to test moving it to different places until you find a stronger signal.

Modem Router Firewalls  

You've protected your computer with a firewall, but in the case of always-on cable Internet, you need to protect the trapdoor, i.e. the modem router, as well as the backdoor. A cable modem router such as LinkSys' EtherFast automatically creates a firewall to double-protect your computer. Of course, if you opt for the equipment your cable Internet service, such as Road Runner, provides, you skip all the guesswork of choosing a modem router firewall. The likelihood that in your cable modem router setup you'll have to install your own firewall is nil. You can however configure your cable modem router firewall to allow faster data download.

Router Hardware 

Beyond your cable modem router setup, like any other computer device, there is physical maintenance. You may be reluctant to tinker with your modem router beyond checking to make sure that the cables between the cable modem router and the cable modem aren't damaged or disconnected. Some hassle-free tips:

• Always upgrade to the latest firmware for the cable modem router or wireless cable modem router in question. Your modem router manufacturer should tell you how to do this.
• Read the specs on your cable modem router.
• Make sure you update the chipset drivers of your modem router hardware, even if the chipset consists of a single chip, to make sure that the chipset works properly and delivers your data packets from the modem to the computer.

Router Troubleshooting 

Common cable modem router problems include:

• Wireless cable modem router not carrying signals
• Network adapter not installed properly
• Network connection from server to modem router not working or not properly installed
• Correct ports not forwarded to the computer and IP number
• Cable damaged between the cable modem and the cable modem router

Make sure your cable modem router setup, whether performed by the cable Internet provider technician or by you, includes a double-check of all the cords and network connections. Also, make sure your network adapter is installed properly and that your wireless adapter isn't in a place where other signals can interfere with your wireless connection.

Replace any damaged or faulty cords as soon as you become aware of the problem.

Always check the information the cable modem router sends to the modem and make sure you know which modem router ports (especially port 80) carry data. At the very least, port 80 should be open.

Installing a Cable Modem Router 

A highly recommended cable modem router is the Linksys EtherFast Cable/DSL Router. Here's a thumbnail sketch of this cable modem router setup:

1) Connect a CAT5 Ethernet cable to the home computer, and a similar cable to each of the four computers on the home LAN the router supports.
2) Follow the neatly organized built-in Web pages to configure your cable modem router. You can also use the Windows configuration tool.

Macintosh and Modem Routers 

Any modem router that connects solely via USB won't work with a Macintosh, since Macintosh uses Ethernet rather than USB. Check your cable modem router setup carefully to make sure your cable modem router connects via an Ethernet and not a USB port.

Fortunately most modem routers have at least one Ethernet port. A good example of a router with both Ethernet and USB ports is US Robotics' USR8200 Firewall/VPN.

Getting the Best from Your Router 

There's a lot you can learn about cable modem routers. If you want to download greater amounts of data (or packets) faster, or if you want to keep your wireless cable modem router from cutting out when the cable signal temporarily vanishes, the best solution is as always to read the documentation, since every cable modem router is different. Also, make sure your network connections are housed separately and cables connected so that nothing can damage them. Your router itself should also be protected.

In your cable modem router setup, especially for a wireless cable modem router, configure your router so that your network timer doesn't time out. This will increase the “on” time of your modem router and keep your connection, smooth.

If you have a modem router and someone else in your home has a router, you may want to change the channel that your router broadcasts on, since two routers on the same channel interfere with each other, cutting out connection and at the very least slowing performance.

The Best Broadband Cable Modem Routers 

Broadband cable modem routers combine the functions of a cable modem, a hub or switch, and a firewall all in one neat package. About.com listed the cream of the modem router crop, factoring in ease of cable modem router setup among other considerations (such as supporting VPNs or virtual private networks):

• SMC 7004ABR Barricade™
• Netgear® RT314
• MultiTech RouteFinder™ RF102S
• Asanté FriendlyNET FR3004
• Nexland ISB SOHO
• 2Wire™ HomePortal 180
• US Robotics® USR8000
• D-Link DI804-HV
• Linksys EtherFast® BEFRS41

N.B.: There's no mention of a cable modem wireless router for broadband.

This should give you a starting point to shop for your broadband cable modem router.

 

How a Cable Modem Speed Tests

My Modem's faster than yours 

More about cable modem speed tests:
You've tested your cable speed and the results read, for example, that your modem loaded 322,649 bytes in 0.187 seconds, with a throughput (see above) of 13803 Kpbs. By contrast, your friend's 56K modem has a maximum download speed of 53 Kpbs.

But don't start crowing victory yet: someone else may have aced the cable modem speed test, possibly even your grandfather. Comparing dialup to cable in a cable modem test is like comparing apples to oranges. Depending on Net congestion for your area, your computer speed and hardware, and whether or not you've done any cable modem tweaks, you might be the slowest cable Internet in the west. But you can improve your cable modem speed.

How a Cable Modem Speed Test Works 

About cable modem speed tests:
Testing your cable modem speed is actually simple thanks to the proliferation of sites such as cable-modem.net. Cable-modem. net's cable modem speed test downloads a harmless file from the Web site server to your computer and measures how fast the file downloads, how many bytes per second your modem transfers, then rates your throughput in terms of kilobytes per second (kbps). Your throughput is the amount of data moved successfully from one place to another in the time the test takes. This will vary from cable modem to cable modem, and bear in mind that your connection speed may be affected by Net congestion.

If you do any cable modem tweaks to improve your speed, and there are many methods out there, you can always do another cable modem test. You should test your cable modem speed regularly anyway, and you might want to keep a log of your cable modem speed test results.

Cable Modem Speed and Hardware Issues  

Wiring issues, rather than hardware, may be the reason your cable modem speed is, well, not up to speed. Check your wiring, have your cable company check the wiring, and then run a cable modem test.

That said, if your USB port is being used by other devices (say a Zip drive or an external CD burner), your CPU will have delays in processing input from your USB, which can affect the cable modem speed. Consider unplugging peripherals while you're doing cable modem tweaks and running cable modem speed tests. Compare the results of the cable modem tests before and after you unplug.

If you use a PCI or NIC card, there's no delay since it's wired directly with the CPU, in which case, as before, your problem is most likely the wiring.

Turn Off That Washing Machine 

The phone's ringing, the oven's going off, and the clothes washer makes a funny noise in the spin cycle. You may feel as if your cable modem speed of your brain has slowed to dialup speed, and you're not the only one. Although fiber optic and coaxial cable is shielded, noise, signals and vibrations from cable TV and household appliances can penetrate, interfering with your cable internet speed. All the cable modem tweaks you can perform won't work if the electricity from your son's Xbox interferes.

Southern California Edison has a program called “Flex Your Power,” trying to get people to use appliances at off-peak hours to save energy. You can use the same strategy. Wash at night; use the Internet during the day or vice versa. When you know you need speed, tell Junior to go to his friend's house to play his video games or his electric guitar. Or do his homework, since other computers and cable modems in the house can affect your computer's cable modem tests.

Unplug a few appliances, disconnect the phone (you want to anyway, right?), and run the cable modem speed test again. You'll be surprised at the result.

Cable Modem Speed on Macintosh and Windows 

Windows cable modem speed complaints are legend. But once you've run a cable modem test on your Windows 95 computer, for example, and discovered you come out the tortoise to your across the street neighbor's hare in the cable speed test, you can actually correct the problem by performing cable modem tweaks and upgrading your Winsock2 version. This will allow you to make the receive window, a buffer that determines how much data the receiving computer is prepared to get at one time, larger.
 

The Macintosh doesn't have a registry to edit, but don't let Mac users get uppity. Macintosh cable modem speed isn't all it could be because it controls communications through the Open Transport layer, which means it's preset to handle dial-up modems and Ethernet connections. Since Mac users are undoubtedly frustrated when the results of cable modem speed tests indicate they're not downloading iTunes, games and graphics as blazingly fast as they want, OT Advanced Tuner is highly recommended in addition to other Mac cable modem tweaking programs.

Linux gets ignored, but it too can make cable modem speed slow. Fortunately, with a text editor, Linux devotees can do cable modem tweaks to their hearts' content.

Cable Modem Tweaks vs. Automation 

Cable modem tweaks fine-tune your cable speed, and as with most improvement projects, there are two routes you can take:

• Do-It-Yourself
• Let Someone Else Do It

As with remodeling your kitchen, working on your car or managing your health and finances, there are pros and cons to going it alone versus letting someone else muck around. So before you decide the results of that cable modem speed test mean you need to be the Lone Ranger, a few considerations:

+ Pro DIY

--You have more control over editing your computer's registry
--There are no unfamiliar programs changing your system except for any registry editing tools you might use
--You know your computer system better than anyone

- Con DIY

--If you don't back up your computer's registry, you could be in trouble should you accidentally punch the wrong key
--You have a learning curve and will need to bone up on registry editing from sites such as SpeedGuide.net
--A computer program (Broadband Wizard and BlazeNet for Windows, OT Advanced Tuner for Mac) to tweak your modem can easily undo any changes you make

Whatever route you choose, always run a cable modem test after you've finished tweaking.

 

How we can use Coaxial Cable for internet?

Alternatives to Coaxial 

Coaxial is the cable Internet standard, widely installed in business and corporation Ethernet and other types of local area network. However, other alternatives can get you online at high speeds. Twisted pair copper wire and optical fiber, better known as fiber-optic, are viable alternatives to the different coaxial cable types. However, this depends on the signal carrier technology used.

Depending on the configuration, coaxial cable may be heavier than fiber-optic cable, which is usually lightweight. However, the heavy shielding of many coaxial cables helps block signal interference from televisions and other household appliances.

Both digital fiber-optic cables and digital coaxial cable are available for use in cable Internet infrastructure, but are designed to carry different signals, optic versus electronic. It all depends on your cable Internet setup which types of digital cables you use.

High-Band Coaxial Cables 

Coaxial cable has an extremely broad bandwidth, especially digital coaxial cable, which tends to prevent loss signals. Coaxial cables have a lower attenuation and can carry hundreds of cable Internet signals. The coaxial is a relatively simple cable, yet it can carry large amounts of data. In the case of telephone and video signals, coaxial cables can handle hundreds of phone conversations and a television program taking up 3,500,000 Hz. Certainly, given this capacity, coaxial cables can handle bandwidths of 2-3 Mpbs. There is no bandwidth performance difference between the coaxial cable types.

Coaxial Cable Safety and Maintenance 

As with any wiring and infrastructure, all coaxial cable types, including digital coaxial cable, require careful handling. Although the coaxial copper shielding is strong, whether rigid or braided, it's not indestructible. Some safety and maintenance tips:

• Make sure your coaxial cables and coaxial connectors are fire resistant (FR).
• Don't buy secondhand, used or cheaply manufactured coaxial cables.
• Make sure coaxial cable shield is grounded for safety.
• If possible, house coaxial cables separately from the rest of your computer equipment and especially other cables and wires.
• Do not expose coaxial cables to water.
• Make sure the cable outlet wiring is intact.
• Keep your coaxial cables repaired with tools such as the Shake ‘n Seal Coaxial Cable Repair Kit.

Troubleshooting Coaxial Cable Connections 

Either your digital coaxial cable or your regular coaxial cable can become disconnected from the cable modem and/or the cable outlet. Check both connections if the cable Internet stops working.

If you are still getting interference from other devices in the home, replace your coaxial with the quad-shield coaxial cables. Also, interference may happen because with all coaxial cable types, the insulation degrades and the cable must be replaced. Also, the coaxial connector or splice needs to be attached to the correct copper screen to provide the return path for the cable Internet signal.

Coaxing More Speed Out of the Coax 

Typically, the data transmission speed through coaxial cables is 10 Mbps. This is true for all coaxial cable types.

Can you coax more speed out of the coaxial connection, especially with digital coaxial cable? You can use a large lower-loss coaxial cable, and use the same cable throughout the signal path, to gain more bandwidth and a higher connection speed. The good news is that coaxial cables are ideal for higher bandwidths.

Ethernet and Coaxial Cables 

Thin Ethernet or 10 Base-2 is a lighter, less expensive version of 10 Base-5 or Thick Ethernet. It uses a lighter, thinner copper coaxial cable. What is the advantage of a sleeker coaxial? Besides skipping the 10 Base-5 external transceivers and simplifying the coaxial setup, thin Ethernet features well-shielded coaxial cable. The drawback is that the RG-58A/U coaxial cable used with thin Ethernet can't be interchanged with other coaxial cable types, including digital coaxial cable. Also, changing the network is difficult since the network breaks easily. Making it difficult to troubleshoot.

Despite drawbacks, thin Ethernet is a simple, inexpensive infrastructure to implement for basic cable Internet networking on a budget.

Separating Cable Signals 

Your coaxial cable setup should prevent any signal interference between your television and cable modem. A coaxial cable splitter is part of your defense system. In addition to the copper shielding, signals going through your coaxial cables, including your digital coaxial cable, are separated by a cable splitter. Cable technicians will install the splitter on the side of your house and run a separate coaxial line to your cable modem. In addition, your different coaxial cable types such as triax, digital coaxial cable, twinax and biax have added reinforced casing and configurations to prevent interference with the cable Internet signal from the television signal as well as other household appliances.

Coaxial Cable Types 

Learn about coaxial cables:

Coaxial cable carries your broadband cable Internet signals. Coaxial cables are the nerves or, if you prefer, veins of your cable Internet connection. The different coaxial cable types are:

• Rigid coaxial, with a solid copper wire sheath
• Flexible coaxial, with a braided copper wire sheath
• Hard line coaxial, a heavy-duty cable with rigid or semi-rigid pipe for the outside shielding
• Triaxial cable or triax, a coaxial with a third layer of shielding, insulation and sheathing
• Twin-axial cable or twinax, a coaxial with a balanced, twisted pair within a cylindrical shield
• Biaxial cable or biax, a figure eight configuration of two coaxial cables
• Digital coaxial cable, suited to any high-grade digital applications such as digital cable and digital cable Internet

Digital coaxial cable is primarily used for audio and home theater, but its powerful connectivity makes it ideal for digital cable Internet.

Managing Data over Cable Surface

Tips about what is Docsis? (Data over Cable Surface Interface Specification)

Docsis Drawbacks 

Data over Cable Surface Interface Specification may be the standard, but it has its disadvantages, as cdlp does. Docsis time-shared bandwidth can clog connections, especially when several users are on the same network, which can slow the data transmission through docsis cable modems. Some critics say that docsis lacks security and quality of service (QoS) as well as nonsymmetrical. Upgrades in docsis 2.0 may allow symmetrical data streams of up to 30 Mbps. The nonsymmetrical and slower data streams can hinder VoIP, but docsis upgrades will allow voice-over to fly through docsis cable modems.

Wireless Docsis 

You've gone wireless, but is your wireless cable modem a docsis cable modem? There are wireless cable modems designed specifically to be Data Over Cable Surface Interface Specification compatible. Motorola's wireless cdlp cable modems have been superseded by wireless certified docsis cable modems/gateways. Cisco-Linksys offers the Wireless-G Cable Gateway WCG200E that is docsis certified. Other wireless docsis cable modems include Thomson's TCM390. For a full list consult www.cablelabs.com.

Docsis 2.0 Modems 

Want to find out more about what is docsis? If you're looking for a Docsis 2.0 modem, fear not: Twenty-two cable modems are now Data over Cable Surface Interface Specification certified. Motorola, the inventor of cdlp, has achieved Docsis 2.0 certification for its cable modems/gateways. To find out if your cable modem manufacturer sells a Docsis cable modem certified for version 2.0, visit the CableLabs Web site at www.cablemodem.com. Modems from Terayon, Texas Instruments and Thomson recently achieved Docsis 2.0 status.

If your Docsis modem is still version 1.1 or 1.0 and your manufacturer hasn't achieved 2.0 status, you don't need to worry, since no matter the version Docsis is the industry standard.

Docsis 

What is Docsis? Docsis stands for Data Over Cable Surface Interface Specification, and is the project of CableLabs. It defines interface requirements for cable modems involved in high-speed data distribution over cable television system networks. Docsis is the “Good Housekeeping” seal for cable modems. A Docsis cable modem has been certified by CableLabs and is thought to be acceptable for commercial sale and for use in cable Internet connections. Previously, the cable modem standard was cdlp (cable data link protocol), a proprietary standard made by Motorola. Cable Internet providers and cable modem manufacturers are replacing or have replaced the old cdlp modems with Docsis cable modems. Although many systems will support both cdlp modems and Docsis cable modems, many networks have converted to Docsis and have abandoned the cdlp networks. Docsis is thought to be a less expensive technology standard for consumers.

Docsis 2.0  

Docsis 2.0 is the latest standard of Data over Cable Surface Interface Specification. Unlike Motorola's cdlp, Docsis 2.0, in addition to the features of Docsis 1.0 and 1.1, offers more secure software for Docsis cable modems, which means added security for your Internet connection. Docsis 2.0 also offers the following:
• Significantly enhanced upstream capacity
• 6.4 MHz maximum upstream channel width
• 30.72 Mbps maximum upstream channel capacity
• Increased robustness to upstream noise and channel impairments
This simply means if your Docsis cable modem is Docsis version 2.0, it offers a faster, more reliable connection than previous versions, which in turn are faster and more reliable than cdlp cable modems.

Not Docsis Certified 

If you're a customer of Australian's Bigpond cable Internet service, Bigpond has most likely replaced your cdlp cable modem with a Docsis cable modem. Bigpond has switched from its cdlp network standard to a Data over Cable Surface Interface Specification network standard.

If you have Motorola's CyberSURFR cdlp cable modem, Motorola also manufactures a hybrid cdlp/docsis cable router, for those of you who don't want to surrender your cdlp cable modem. Although Net posters have proclaimed, “CDLP is dead, move on,” some cable modem buyers prefer the cdlp system. That said, most cable Internet providers and cable modem manufacturers favor Docsis.

EDocsis 

EDocsis and Docsis Set-top Gateway (DSG) are two new Data Over Surface Interface Specification projects being developed by CableLabs. The DSG integrates docsis technology into a digital set-top cable box, makes it Web-enabled, and increases the two-way capabilities of the average docsis cable modem currently on the market. Its technology is to current docsis cable modems what docsis cable modems are to cdlp cable modems. You can get Scientific-Atlanta's Explorer 8300 (TM) system, the first digital cable box system to be DSG certified.

EDocsis stands for embedded docsis, which feeds directly into a cable network's docsis channel, Web-enables cable boxes, and solves end device/traffic management, configuration and security issues to reduce customer cost and improve speed and quality. EDocsis is the basis for DSG, and thus for Scientific-Atlanta's Explorer 8300 (TM) system. If you want a more integrated cable TV/Internet experience that can give a larger multimedia experience, eDocsis and DSG may be for you.

Method and Technique about Installing Coaxial Cable 

Detecting Coaxial Cable Wiring Faults and Installation Mistakes

You might not know from a visual inspection that you've made mistakes in your cable coaxial installing, or that your coaxial cable wiring is faulty. You might have used a poor grade of coaxial cable wire in your installation.

You can invest in a coaxial RF cable tester, an inexpensive gadget (around $50) that can test a wide range of coax cables and identify wiring faults by LED lights. A coaxial RF cable tester can test up to 4 different cables at one end. While it can't detect problems in cable connectors or help you correctly install coaxial cable connector, it can avert trouble. Before you start your coaxial cable installation, buy a coaxial cable RF tester.

Different Types of Coaxial Cable Connectors

The most common type of connector used in coaxial cable installation is the Bayone-Neill-Concelman (BNC) connector. Different types of adapters are available for BNC cable connectors, including:
• T-connector,
• barrel connector
• terminator
When you install coaxial cable connector, always use the BNC connectors that crimp, rather than screw, onto the coaxial cable. Cable coaxial installing goes more smoothly with the right coaxial cable connector.

Common Cable Coaxial Installing Error 

Installing coaxial cable advice: The most common cable coaxial installing error happens when you install coaxial cable connector. Crimp-on connectors, the preferred standard cable connectors for coaxial cable installation, are for stranded (twisted) coaxial cable.

Examine the cable connectors closely and you will see a row of “teeth” on the underside of the exposed connector pins. These teeth pierce the cable insulation to make electrical contact with the copper wire. Using a crimp-on connector designed for a solid cable on a stranded cable, and vice versa, causes an unreliable connection. If you have terminated the cable connection incorrectly, the connector will become separated from the cable. Uninstall the connectors from the cable ends and reinstall the crimp-on connector on another coaxial cable, stranded or solid depending on which type of connector you have.

It's important to use the correct tools for coaxial cable installation. One recommended tool is the Thomas & Betts Snap'n Seal ® Tool that creates a more secure bond between the cable connectors and the cable. Thomas & Betts also manufactures a Snap'n Seal ® male connector that protects drops from harsh environments such as cable connections in winter climates.

Different Types of Coaxial Cable Connectors 

More installing coaxial cable advice:

Cable coaxial installing is fairly simple if you remember the basic steps:

1) Install coaxial cable connector to the cable TV and cable modem cable connectors.
2) Install cable adapter (also called a splitter) to split the signals between the cable TV and cable Internet.
3) OR install 3-foot coaxial cable to go from cable outlet to splitter and 25-foor coaxial cable to go from splitter to cable modem
4) Use nail-in cable clips to secure cables to the wall

Cutting Coaxial Cables 

When trimming the coax center conductor to 3/16” length for proper coaxial cable installation into dual crimp coaxial cable connectors, use the same care as with cutting other types of wire or with other cutting tools. Cable coaxial installing shouldn't result in a hand injury. Always safely store your coax cable cutters.

Remember to double-check your trimming; otherwise you'll have difficulty when you install your dual crimp coaxial cable connectors.

Always use the best coaxial cable cutters. You can find good quality coaxial cable cutters at your local electronics store

 

Uncapping Cable Modem

ISP Caps on cable modems 

ISPs frown on bandwidth hogs, and hackers who uncap cable modem limits with a cable modem un capper or an uncapping machine.

Cable Internet providers and ISPs don't limit bandwidth to make your life miserable (that's what dial-up is for.) They do it to prevent people from running huge bandwidth-hogging Web servers on their cable Internet connections.

In addition, ISPs have a whole network of customers to distribute bandwidth among. It's the same principle as parents giving every kid the same allowance – it's just fair to everyone.

Uncapping and Docsis 

One tutorial on the Internet gives you an uncap cable modem tutorial that includes instructions on how to change Docsis specifications. We won't post the instructions here. Altering Docsis is like backing up in an area with warning signs saying, “Do not back up, severe tire damage.” Uncapping machine, cable modem uncapper, the tool doesn't matter. Your ISP/cable Internet provider monitors Docsis specifications and can look for red flags. Besides, the speed increase will be negligible.

Uncapping=Increase in Bandwidth? 

Stealing bandwidth is illegal. The chances that you'll gain insane amounts of bandwidth by using a cable modem uncapper or uncapping machine are negligible, and not worth getting banned from your ISP for life plus jail time. Most high-end servers can only handle 8 Mbps. Hackers on the net may be saying, in ungrammatical posts, “Uncap cable modem, u know u want too,” but you can't enjoy the bandwidth boom from the county jail.

Uncapping Alternatives 

More uncapping cable modem tips:
There are many terrific cable modem speed tweaks out there. You can increase your speed and bandwidth without ever needing:

• An uncap cable modem tutorial
• A cable modem uncapper
• An uncapping machine
• A hacker

There are excellent speed optimizer programs for purchase and available as freeware or shareware. Alternately, you can change your computer's settings yourself without needing to do anything to your cable modem.

OneStep Cable Modem Uncap 

OneStep is supposed to be the Arnold Schwarzenegger of cable modem uncapper programs, a lean mean uncapping machine.

The brainchild of shadowy criminals calling themselves “DerEngel” and “Byter,” OneStep sends disgruntled cable Internet subscribers into frenzied anticipation. But Netizens content with 3 Mbps and unwilling to face exile in the form of dialup advise against buying into the uncap cable modem program, although DerEngel reportedly insists OneStep is legit. DerEngel also plans to provide disclaimers and warning statements for those who want the mammoth 30 megabyte program.

OneStep is supposed to make uncapping safe, but many Netizens say to steer clear.

ISP Monitoring of Cable Modem Uncapping 

Your ISP and/or cable company monitors the network. If your neighbors hold an “uncap cable modem” party, the ISP can detect that your neighbors' bandwidth is above specified limits. The ISP can query the network to find your MAC address (not to be confused with Macintosh) and identify you as the source of the uncapping. In addition, many ISPs have modified the config file sent to the modem to detect when the cap is exceeded, at which point the modem shuts down. No matter how clever the uncapping machine or cable modem uncapper, the ISP can still catch you.

Legally Uncap Cable Modems? 

If you're thinking about uncapping your cable modem, especially if the modem cable with a cable Internet service provider, be warned. Your service agreement prohibits uncapping, removing software blocks that limit or “cap” bandwidth.

Uncap your cable modem and you will at the very least be banned from your ISP for life. In the case of subscribers who uncapped cable modems provided by Buckeye Cable of Ohio, the FBI seized the offenders' computer equipment, although reports suggest this may have been excessive punishment.

Some critics argue that the laws about cable modem uncapping are not clearly defined. But most of us would probably do well to avoid an uncapping machine or a cable modem uncapper.

Cable Modem Uncapper 

Uncapping cable modem tips:
A cable modem uncapper is a program floating around the Internet that uncaps the bandwidth limits either included in your cable modem or programmed in by your cable Internet provider. It's available in a Zip file, but be advised that using this program to uncap cable modem equipment will at the very least get your ISP service terminated. Thanks to Docsis and to the cable company monitoring users' modems for bandwidth hogging, using the cable modem uncapper program is in the category of “use at your own risk,” much like an uncapping machine.

There are also other uncapping programs users have offered in internet forums, including links to sites devoted to cable modem hacks. Again, this is murky territory.

Uncapping Doesn't Work 

Several uncap cable modem proponents will tell you that they've been able to coax ten times the bandwidth out of their cable modems since they've run a cable modem uncapper or used and uncapping machine.

However, most tech experts agree that uncapping doesn't work, except on older modems. Also, experts say the bandwidth limit is enforced at the head end, and there's no way around this design. In the event you do increase the cap, you have to reboot the cable modem to make the change permanent, but once you do, the modem will contact the head end computer and download the latest settings, including the speed limits, which are most likely the ones you just tried to bypass through uncapping.

Uncapping Tutorials 

Like specs on how to create viruses or how to start your own MLM business, tutorials on “how to uncap cable modem” are abundant on the Internet.” They feed the perpetual motion uncapping machine started by a few hackers and cable subscribers dissatisfied with their cable Internet service.

Like cable modem uncapper programs, cable modem uncapping tutorials are questionable at best, illegal at worst. If you do some research online, you'll find that cable modem uncapping tutorials are usually posted by poor spellers in tech forums. Most cable modem users treat them with about the same credibility as junk e-mail advertising.
