I've been using macs since 2000 or so, but my brother just bought a dell and he was planning on just *cough* borrowing the neighbors network (which i'm on right now). i tried setting up his linksys notebook adapter, but i can't seem to get it to work. anyone know how do this stuff on the PC? probably not the right crowd, but don't know where to turn. in the bottom right it shows there is a signal, but the computer deal has an X and won't connect. first off, should i be using adhoc mode or infrastructure mode? any ideas on how to get this going? thanks in advance for any help.
