Any y'all had problems with Linksys? My roomate installed it on his pc so that we could use our laptops around the house. Problem is, his laptop can sometimes get online but not mine. He has Windows XP while mine is Vista. But here's another twist; this is a newer Linksys that replaced an older unit he had. Both of our laptops worked fine on the old Linksys and until finally neither one of us could connect online (thus prompting the newer purchase). If y'all know anything, please share.
