wireless help

[adams]

ok I have a wireless modem that came with my dsl and a wireless card in my computer. now someone around here has the same modem(different model) and for some reasaon my connection drops (my computer is about 4ft. away from the modem) and the wireless card connects to thier modem which leaves me without an internet connection.

Is there anyway I can tell it to only connect to my modem and not the other one?

It sounds like either yourself or your neighbor has an open connection, not good from a security standpoint!
The chances are that both of your computers are using the same channel for the wireless networks, you should be able to change that in the modem/router configuration and also on the wireless card settings in your PC. You may want to configure your network's security, i think the usual security is called WPA-SK, whatever it's called you should be able to limit the connections to and from your computer by requiring it to have a shared key (password you decide upon). This can also be set in the above locations.
Did you get a manual? i'm pretty new to wireless myself so i only have rudimentary knowledge, i'm not up to spec on all the types of router and modems out there. Whatt make/model of router is it? if i can download a PDF i might be able to help.

Make sure you don't have any cordless phone base near by, as those too cause problems with your signal strength reception.

ESPECIALLY 2.4 ghz cordless; 5.8 is not a problem, but the other ones are...

Not just phones, but xboxes in some cases, ps2, radios, etc. Well pretty much any electrical device. Even my monitor if too close can nock it out.

Dog got it pretty much right. For information on your router/modem see:
