I purchased the MiFi so that my partner and I didn't have to fight over who would get to use the internet connection. I went out and bought two Belkin Wireless G USB devices so we could both connect. Well, connection is sketchy, sometimes it will, sometimes it won't. If one of us is connected and the other tries to connect, the person who was on is kicked off and can't connect again.
Both desktops are using Windows XP, one PRO-SP3, the other Home-SP2.
