Cable Modem Frequently Asked Questions

What is a cable modem and how does it work?
A cable modem is an external device that has two connections, one to the cable wall outlet and the other to your computer and allows high-speed access to the Internet using cable TV (CATV) wires instead of telephone lines. Cable modems translate radio frequency (RF) signals to and from the cable plant into Internet Protocol (IP), the communications protocol spoken by all computers connected to the Internet. A cable modem allows consumers to access the Internet in a fraction of time it takes using a regular dial-up modem. Downloads can be up to 100 times faster allowing consumers to watch smooth streaming video, listen to CD quality audio, and trek from web page to web page in lightning speed.

Since I am using a cable line, can I watch TV and surf the net at the same time?
Yes. Cable modems send and receive data from your computer using cable frequencies that aren't used by television signals. Someone in your household will be able to watch their favorite TV show, while someone else can be online.

Does my computer have to be next to my television set?
No. Multiple TVs and computers can be served off of the same cable line. Just like telephone jacks or cable television outlets, different wires can be run to almost anywhere in a house.

I heard that cable modems are "always on." Is that really true?
Yes. With cable modems, you are automatically connected to the Internet. If your computer is on, so is the Internet. It is not necessary to log on or log off, or to dial a phone number to get a connection.

I have an AOL account, will it still work or will it become useless?
It will most definitely work. You will still be able to access AOL through your cable modem connection.

Is a cable modem compatible with PC and Macintosh? What are the requirements?
Cable modems will work with PCs and Macs. You will have to check with your cable provider to for the minimum system requirements.

How do I install a cable modem?
Your cable provider will come out to install your modem service just like they come install your cable service. You can also check and many of the cable providers or their retail partners have self-installation kits. Either way—it is real simple!

I thought DSL and cable modems were the same. Is there any difference?
Although both cable modems and DSL (Digital Subscriber Line) are broadband technologies, there are many differences. DSL is a telephone modem technology that runs though traditional copper wiring. It uses the telephone line to carry digital data to and from you computer to the Internet, but in order for the DSL signal to work, the copper wire must be less than 18,000 feet away from the Telephone Company's central office. Also, finding out if DSL technology is out there can be complex, because even if an area is DSL ready, your house or phone line may not. And, since DSL only provides your connection, to get to the Internet, you have to find, and pay for, an ISP.
