I want a new modulator-demodulator

**mcovey** · June 19th, 2004, 07:32 AM

Does anyone here know if you can use two modems in the same house? We need to hook up another computer that's too far from the router without installing wires, so can you use TWO modems? I am just worried that i'll spend $50 and then my modem wont work because you're only able to use one. if anyone here knows from experience or something, please do tell!

Thanks!

EDIT:
I almost forgot to mention that it's a cable modem.

One option would be to get a wireless router. That would cost a little more though; about $60-80 for a wireless router and $30+ for a wireless card for the system.

You mean you want to run two modems off one cable? That won't work, you'll need two cables to do that.

I'd take DampCold's advice and get a wireless router - they're pretty cheap now, especially 11Mbps 802.11b ones.

No, we have two cable plugs, one downstairs and one upstairs (and some other ones but they dont matter). the one upstairs has a cable modem on it and what I want to know is if I can use two modems on two seperate lines, but with one service (one monthly bill).

We have a wireless router but it doesnt go far enough, and we can't wire the house for ethernet.

So two cable plugs, two rooms, same house, same service that we're being billed for --- Possible?

If it's two seperate cable lines coming to your house, it'll be down to the policy of your cable supplier - many don't allow two internet lines unless you have a business account.

Don't forget that you'd have to have two seperate connections - so you couldn't 'share' your (for example) 1Mbps between the two - you'd have to have two internet subscriptions, although I guess it would be fine to have it on one bill.

Have you considered getting a wireless network bridge?

Buy two bluetooth USB adaptors and go wireless.

well my other option is to string the cat5 cable out the window, bury it and stick it into the basement window (my room is down in the basement) and put it in my room. It'd have to be a long cable, though. Looks like I'm gonna have to email adelphia and ask them.

CAT 5 cable (Im assuming youre using) can go for 100 meters before the signal deteriorates. You could just wire it through your house to your computer and connect it to the router (Unless you have a mansion, a 100 meters should be enough :)) It would be the cheapest way, but would take work.

Or you could just go wireless with everything. That will set you back a 100+ dollars.

**mcovey** · June 19th, 2004, 01:03 PM

That's my idea, siskabush, but my dad doesnt want me to do that for some reason.

I'm awaiting a response from adelphia tech support, but I'm fairly sure that there should be no problem with 2 modems.

If the wireless router won't reach both computers in it's current position, move it. Put the router in the exact middle, or as close to the middle as the nearest cable plug. Other option is to get a different router that has longer distance, I'm not sure what to reccomend here.

"Does anyone here know if you can use two modems in the same house?"

Cable modems run off of your cable tv line, which is seperate from your telephone line.
Regular modems run off your telephone line.

You could not network a modem to call your own house to connect it to the network.

There is a networking option that may be available to you.

There is a device that you can network your home using the electrical outlets of your home, and they plug right into the network card of your computer, and your power outlet.

Its called a power line ethernet bridge, one RJ45 (ethernet cable per plug).

Pretty nifty stuff.

Only drawback I see is they would have to be on the same circuit in your house and you probably have more than one...I would flip the circuit breakers in your house to see which ones you can connect where to get an idea of maximum distance you can plug these bad boys into.

Well, hope you get situated.

Make sure you read up on possible noise interference if you decide to do something like that. Maybe google it with reliability. I am not quite sure what frequency range Ethernet works on, but if it is far enough away from 60Hz I don't know if noise would still be too much of a problem.
