I bought two of these for two different computers. One is a straight windows XP OS and the other one is XP media edition. In a nutshell, the adapters fail several times a week and you must go through the whole install process again to get them up. Repeated calls to Linksys have been no help. I will never, never buy another adapter from them. 20 years of computing and these adapters have been the worse products I have ever bought for any of my computers. Please note, we are talking not just one adapter and computer but two. I gave up on one machine and just ran CAT 5 but the other is yet to be resolved. Oh and stupid me has been putting up with this for over a year now. So, sorry but I cannot recommend for anyone to buy these adapters.
