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.

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.
-
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.
-
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.
-
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
-
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.

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.

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.

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.
