well, a couple of questions.
you say you are using a wifi card right? what kind of modem are you using? cable ? DSL?
what type/brand modem and router are you using?
And just for information, is your setup connected like this:?
Internet source (DSL jack/Cable) --> into Modem -->into router (wireless i'm assuming)
Which should connect or at least display the new card you installed in your computer.
Also, did you use any of the software that came with the actual card? sometimes you have to use the wizard or control program specific to that card. (Utilities)
also, and this is just one of those "simple things making things work like crap" kind of deals, but check to make sure ALL your wired connections are in fact connected securely.
Hope this helps!
