content: It took me 5 minutes to set up the unit on my XP Pro machine. Everything worked fine if WEP was not considered. However, security is a big thing these days - at least to me.After spending almost 4 hours - resetting my SMC router, network settings, etc. It simply would not work with WEP enabled.The unit itself is good. But if you want WEP on XP, you might want to try something else. That's what I am going to do.
