I've got a wireless 802.11b network at home. Everything in my house had "b" capability except I'm not sure of one laptop (inspiron 600m; maybe this has b/g capability??). Please correct me if I'm wrong here. Ok, so my question is... if I should by a Dell laptop (not sure which model but less than 0) which has an internal 802.11g card, what are my options to make it get on my home network? Can I swap it out with a "b" card? It would be a rather expensive upgrade to swap out all my computers at home (several plus the router) so I'd rather not do that unless I have another reason to and besides, if I do that maybe the "pre N" or eventually the "N" card would be wiser. What are my options here? thanks in advance all.
