Cable Modems

How many times have you sat there starring at your computer screen,  twiddling your thumbs, just wishing you had even a little more speed? This particularly holds true for anyone that is still using a standard dial up server, which can be painfully slow. If you have found yourself wishing for more speed from time to time, then the good news is that it is now not so far out of reach.

Cable Modem Speed is Measured in Kilobits Per Second

A cable modem speed test is a test by which the speed that your computer operates on the Internet can be guaged. Internet speed is measured in kilobits-second and for most people this means how fast data files can be downloaded. However; the speed by which your system operates also has an effect on how fast data files are uploaded as well. Most people are only concerned with their download speed though, as this is what they find themselves doing most of the time that they are on their computer.

The Most Accurate Test Available

There are now online service that can not only test your computer services overall speed, but they can also assist you in implementing measures to increase your performance speed as well. The cable modem speed test is administered by the service sending your computer a data file of a measured size. This file is then downloaded by your computer end then uploaded back to the sender.

Achieve Maximum Speed Attainable

In this way, both your download speed and your upload speed are combined in to one figure that is your total result of the cable modem speed test. This is far better then testing only your download speed, which can be done by yourself by simply timing the speed of a file download with a stopwatch. Also, another benefit of using an online service is that they can automatically retest you as you are implements upgrades, until you have reached the maximum speed attainable.

How are Cat5E and Cat6 different?

The general difference between category 5e and category 6 is in the transmission performance, and extension of the allowed bandwidth from 100 MHz for category 5e to 200 MHz for category 6. This includes better insertion loss, near end crosstalk (NEXT), return loss, and equal level far end crosstalk (ELFEXT). Improvements, such as described, provide a higher signal-to-noise ratio, allowing greater reliability for current applications and higher data rates for future applications.

Category 6 will eventually supercede category 5e. Analyst predictions and
independent polls indicate that 85 to 95 percent of new installations will
be installed with category 6. The fact that category 6 link and channel requirements are backward compatible to category 5e makes it quite easy for customers to choose category 6 and supersede category 5e in their networks. Applications that worked over category 5e will still work over
category 6.

Because of its greater transmission performance and better immunity from
external noise, systems operating over 6 cabling will have fewer errors vs. category 5e for current applications. This means fewer re-transmissions of lost or corrupted data packets under certain conditions, which translates into higher reliability for category 6
networks compared to category 5e networks. Category 6 will be very effective in the residential market to support higher Internet access speeds while facilitating the more stringent Class B EMC requirements (see also the entire FCC Rules and Regulations, Title 47, Part 15). The better balance of category 6 will make it easier to meet the residential EMC requirements compared to category 5e cabling. Also, the growth of streaming media applications to the home will increase the need for higher data rates which are supported more easily and efficiently by category 6 cabling.

Applications:

-100 BASE-T; 1000 BASE-T; 10 BASE-T (IEEE 802.3)

-100 VG-Any LAN; 4/16 Mbps Token Ring (IEEE 802.5)

-55/155 Mbps ATM; 100 Mbps TP-PMD (ANSI X3T9.5)

-Voice

-Cat6 and Cat5e cable designed For: Network Adapters, Switches, Hubs, Routers, DSL/Cable Modems, Patch Panels and other twisted-pair applications

CAT5E cable definition:

Ethernet cable standard is defined by the Electronic Industries Association and Telecommunications Industry Association. CAT5 is the 5th generation of twisted pair Ethernet cabling and the most popular of all twisted pair cables in use today The Category 5e standard is now officially part of the 568A standard. Cat5e is recommended at a minimum for all new installations, and was designed for transmission speeds of up to 1 gigabit
per second (Gigabit Ethernet). Maximum length for CAT5e cable: 100m

CAT6 cable definition:

CAT6 is an Ethernet cable standard defined by the Electronic Industries Association and Telecommunications Industry Association (commonly known as EIA/TIA). CAT6 is the 6th generation of twisted pair Ethernet cabling. Cat6 contains four pairs of copper wire and unlike CAT5, utilizes all four pairs. CAT6 supports Gigabit (1000 Mbps) Ethernet and supports communications at more than twice the speed of CAT5e, the other popular standard for Gigabit Ethernet cabling.

Fake advert for cable modems.

When you want to access the Internet,you want to have the fastest Modem connection possible.And the dialup modem will do if you want just email basic surfing.

The faster cable or dsl are a must have for such internet downloads of large files,super faster web page access, and viewing videos online.

Installing your new modem, whether its dialup, dsl, or cable, it can be a breeze when you both make the installation an education experience as well as having fun in the process.

For this to happen, you must be prepared with the right equipment. High speed modems will need an ethernet card in most cases,for example.

Let’s take a deep down look at what it will take to get a new Internal or External modem up and running in your computer.

While we’re at it,we will see what it takes to install a cable or dsl modem as well. These modems are always external but will need a couple for parts in order to get that fast internet speed.

Connecting Modems To The Computer

When installing your Modem, first right down the serial number for use should you need to contact technical support.

External modems are connected to the computer with the RS232 cable. This cable is connected to the rear of the system at the serial port and the modem itself. Some modems will have this cable as a part of the modem.

Internal modems are inserted in an expansion slot on the motherboard,unless its integrated with the motherboard.

Provide power to the external modem with the use of the adapter that with the modem. Internal modems get their power from the expansion slot right on the motherboard.

After the modem has been installed,both the external and internal modem must be connected to the analog phone line. Plug one end of the phone cord to the jack labeled Line on the modem and the other into the phone jack.You can then connect your telephone to the phone jack on the modem.

Installing Moem Software

Now you can replace the system unit cover if you are installing an internal modem. And after all peripherals are re-connected to the computer, boot the computer.

With external modems,simply turn the computer and modem on.See if the power indicator is on.

If you have Windows 98 installed,insert the floppy disk or cdrom containing the device driver into the appropriate drive when the “add new hardware” screen appears. Follow the instructions on the disk to install the device driver.

Be sure to read the modem install manual carefully to be sure all installation procedures were followed. Click on finish once Windows find and install the device driver. Users of Windows XP have an updated list of device drivers which may be present. Its best to use the disk when installing the software.

Testing YOUR NEW MODEM

The device driver allow your modem to talk to your computer.To see if the modem is working,click on Start,Settings,Control Panel,and click the Modems icon.

Read the description of the modem to be sure it is the one you have.

Windows XP users should click on Start,Control Panel,and click the Phone and Modems icon.Then click Modem,Properties,and Diagnostics.Run a Query Modem check to verify your modem is up and running.

Installing The Cable Or DSL Modem

Cable Modems are external and are connected to the computer by a Cat5 Cable. This cables looks like a regular modem data cable but is larger.

One end of the Cat5 Cable is inserted into the rear of the cable modem while the other end is inserted into a Network Interface Card.

This NIC card must be installed in an empty adapter slot in the system unit and transfer data between the computer and modem.

With the Cat5 cable connecting the modem and PC together, you must provide the Internet signal to the modem by connecting a coaxial cable to the modem.

This cable provides high speed internet access and may use the same connection as your television. One end of the coaxial cable connects to the modem and the other is connected the cable TV connector.

If the connection is being used by the TV,a cable adapter will split the signals and you can use one connector for both your TV and the Internet.

DSL Modems also use the NIC card and Cat5 cable. Some DSL modem require device drivers and either a cdrom or diskette should come with the modem.

Once you connect to the Internet with a cable or dsl modem,you’ll most likely never go back to the slower dialup version.

On the other hand,you just may want to keep your dialup modem once you realize just how much more you’re going to invest when it comes to broadband Internet.

Since the choice is yours, learn all you can about all modems, how they work, and how they connect to the world wide web. Your internet experience will grow by leaps and bounds if you do.

I am getting a ps3 and need to find out how to get the internet working on it soon, and my dad won’t get wireless internet. SO Could I just wire a 50 foot ethernet cable through the house from my Cable Router up to my PS3?.. Sorry if this is a stupid question, I am just praying for a way to get internet on my PS3 without wireless…

zexx_xion3 asked:


So i have cable internet and i want wireless. i have a usb adapter but no router yet. what i want to know is if i get a router do i have to call my cable company to use the router or will i just have it?

doitmyself asked:


When weather is less than app. 80 degrees I have internet service. When it gets hot I lose service. The cable company installed it on the eave of the roof, but laid the 75 ohm cable across the roof. I moved the cable so that it no longer ran across the roof and gained another couple of hours during the day of connection time.

One of the contractors they sent said that if we could use the outdoor cabling the company uses we would probably be fine, but the company won’t allow them to use it indoors.

Since we have no crawl space to run wires. Do they make heat resistant 75 ohm cabling? Or can I increase the signal to the cable modem with an amplifier. The cable company hasn’t offered any options except drilling through the walls, which really won’t help. I have 3 TV’s and my cable modem. TV pictures are fine. Internet service works great when it is up and running.

Any ideas?
Internet service goes down when sun is shining and above 80 degrees. ISP has been out and says house need to be rewired with new RG6 cable. I rerouted their installation so that 50′ of app.350′ of outside cable was no longer laying on roof of house (took 50′ off roof and ran that through eave of house and now I get about 2 more hours of internet service each day - TV service is always fine). ISP has checked signal coming to house from pole and says it is sufficient. They last guy out said that heat was a factor. I asked about a signal booster and they said they didn’t like to do that, but I have a friend who said they installed one for him. I think the run from the pole to the house is too long and since it is in full sun all day much of the signal is lost before it gets to me. I need someone with technical expertise to explain what’s happening. Does anyone have any ideas? Do you know of a cable from high heat installations? What kind of booster can I get to install in the house?
We can’t drill through wall because there are 3 TV’s and internet service in different rooms to they have to go throughout the house. Drilling would only bring it into one room.
