its my sisters computer...
i don't like mac's and can't really use them (more of a *nix fan)... no 2.4ghz phones near the router, and i also assume that's not the problem because i have 2 other computers that connect fine, and 1 windows not connected not wirelessly. i do have (many) other cards, but i cant use them because my sister won't use non-mac stuff.(?) and i'm not going to try to install another airport card because i have many other cards. basically there's nothing else i can do correct?
