My home router is a 2Wire g-b, and my new Pearl can't find it--no networks found

Again 4 laptops connect flawlessly (and usually find 3 other networks besides) ... WEP--I know the code by heart I've tried so many times. I'm bummed about this, as I paid extra to get the 8120 instead of an 8110 or 8100.
I will try what the user above said, and see how that works ... and let everyone know. Seems that people have either no problem connecting ... or no luck. I've read somewhere that the broadcast channel may make a difference too ... any thoughts on that?
