Looking to go wireless on my Desktop, its XP service pac 2, Im running a 655 router as well. My question is it worth buying a 552 desktop adaptor or better to use a 556 or should I just go with the 160 USB? I would hate to buy the 552 or any of these if all Im gonna have is problems. I have read alot in the 552 and 556 product forums but I see people seem to have alot of problems, or so it seems. Just want to go the best route the first time if possible. Any input Id greatly appreciate.
