Can someone run me through the steps required to set up a cable modem in dos? I am running 6.22 with a lan client set to work as a server. Can I use my cable modem??? I have a ip. What else do i need?

Modem is a device which MOdulates and DEModulates the signals. Cable modems can be part modem, part tuner, part encryption/decryption device, part bridge, part router, part network interface card, part SNMP agent, and part Ethernet hub. Typically, a cable modem sends and receives data in two slightly different fashions. In the downstream direction, the digital data is modulated and then placed on a typical 6 MHz television channel, somewhere between 50 MHz and 750 MHz. Currently, 64 QAM is the preferred downstream modulation technique, offering up to 27 Mbps per 6 MHz channel. This signal can be placed in a 6 MHz channel adjacent to TV signals on either side without disturbing the cable television video signals. Typically, in a two-way activated cable network, the upstream (also known as the reverse path) is transmitted between 5 and 42 MHz. This tends to be a noisy environment, with RF interference and impulse noise. Additionally, interference is easily introduced in the home, due to loose connectors or poor cabling. Since cable networks are tree and branch networks, all this noise gets added together as the signals travel upstream, combining and increasing. Due to this problem, most manufacturers use QPSK or a similar modulation scheme in the upstream direction, because QPSK is more robust scheme than higher order modulation techniques in a noisy environment. The drawback is that QPSK is "slower" than QAM.

Wow... Thanks - Now i understand how it works. So how do i set it up in dos???

dos is simpler than windows(it dont have plug n play), just plug it in the computer. Its up to the application that will use the modem to configure it all.

That seems like a simple enough answer but it does not seem to work. I have a packet driver for my ethernet card. And it works. And i get an IP. But i can not ping out, and web browsers dont work.

Sorry to sound patronising, but have you tried the simple things, is it attached to the phone line? You mention an ethernet card? is this the modem? have you got a dos web browser? The web browser should detect the modem installed and do the rest for you.

We are talking CABLE MODEM - Not PHONE LINE.
