hello all, i have a revision A iMac G5, and i'm in the market for a wireless card. i've looked at the airport extreme, but its only 54 mbps. is there any other wireless card that i should get? i'm at college, so i don't need a router. should i look into getting a USB dongle? i've heard good and bad things about these. any recommended wireless cards would be greatly appreciated. if you could also state why you recommend it (personal experience, etc.) that would be extremely helpful in making my decision. thanks!
