cable modem question...

[Chloraseptic]

i had a friend over a few months ago and instead of using sharing hardware or software to share the connection, i just had him plug his cable modem (we both have the service, he just came over) into my television connection. it seemed to work fine and i was wondering if there was a difference between the two.

thanks.

So in other words you both were using seperate cable modems at one location to access the internet?

Is there a difference between the two modems?

There are a few cable modems out on the market.

If you are going threw the same ISP as long as both modems are provisioned in there system it will work in any location that has cable service. Some companys do not allow Static IP address to work on certain modems. I.E. We use ComPort propiertary that will work with static IP's. But if you were to hook up a DOCSIS modem and tried using the same static IP it will crap out on you.

Pretty much DOCSIS is the standar for cable modems now, so as long as you have the same ISP and the modems are provisioned it will work fine. If you were to purchase a cable modem, the actual ISP will have to provision the MAC Address of the modem first before it will work so DHCP will recognize it.

i think i phrased the question poorly.
what i meant was, what is the difference between the line my tv is plugged into and the line my cable modem is plugged into, and can i switch between the two. IE, could i move my room around so that my computer plugged into my now tv line and my tv into my now cable modem line.

thanks again!

No difference between the TV and the Internet connections.

You could even put a splitter on (for example) the cable modem line and have both running from the same leg (like to feed a TV tuner card in your PC).

The usual cautions apply: everytime you put in a splitter, you are cutting the signal to each leg by more than half (there are some losses in the process). If you use a three or four-way splitter, you're down to less than a quarter of the signal on all legs.

The moral of the story: if you only need two conenctions, only use a two-way splitter (and so forth).

Good Luck

They are the same exact lines, however, only one outlet will be activated for the cable modem.

For example, your cable modem is currently on an outlet in a bedroom, if you hook it up on an outlet in the Living Room it will not work.
