quick cable modem question

modena · 01-26-2005, 07:55 PM

I have cable internet and a cable modem on the first floor of my house, would it be possible to connect a second cable modem upstairs to get internet while having the first cable modem continue to get internet? Or are they going to have to activate a second account and charge me for it?

All you need is a router. It will allow for 2+ connections the internet from the same modem. I just got one from Best Buy for $39, you can get them online for less than $20.

i know i can get a router, that is not the option i want, as i have interference in between the two points, i just specifically need to know is if i can have a second modem set up and get internet as I stated in the original post. thanks though

You will get charged for the second modem. It won't be as much of a charge as the first one but it will be a significant amount - I don't recommend you doing that.

You may want to try a switch instead of a router.

My friend just purchased an adapter that sends a signal through your power outlets in your house... dont ask me how it works but it is supposed to work pretty well.

cool thanks, if you hear anything else about that, let me know!

It's antiquated technology but it's called HomeRF. I believe it was supported by Intel and 3com. If you do a search for HomeRF or powerline networking you should be able to find stuff on it.

Could just use a coaxial cable splitter from Radio Shack- should be only a couple of bucks, but like was said earlier, if you have a second modem you will have to pay more. Router is probably the best way to go.

If you're worried about interferance, either change the wireless channel on the router you're using or buy a different standard. If you're using 802.11B or G you can switch to A which uses a diffferent frequency spectrum. I'd also suggest looking at bridging two routers. The Dell home routers can do this out of the box. It is when you have to separate routers that talk to each other to extend the network.

you can buy another cable modem on ebay or somthing i had 3 at one point + they all worked, or just go to the store and buy another one with your hard earned money and not try anything that could get you in trouble.

I don't know how you're cable company works, but mine goes by the MAC address of the cablemodem. If they see a new cablemodem on the network, it has to be registered with them within 9 days or they disable it. So your suggestion won't work if going around the cable company is your intent.

Joshua is right. Most likely your cable company will not allow another modem to communicate without charging you for it.

Your best bet would be to get a wireless router (g is best) and a g-type PCI or USB 2.0 reciever.

cool, i changed the channel, i was having interference on channel 11, and i put it on 3, works perfect now, by the way, are 1 and 11 close channel wise, or are they the furthest apart?

AlpineJay · 01-28-2005, 02:19 PM

1 and 11 are the furthest apart. 1, 6, and 11 also happen to be the most frequently used bands by cordless phones and wireless APs.
