Thanks very much for that info! It does not crash when using the older router. I'll check about what I can do to the new router to tell it to allow b connections--right now I don't have the new router because I had given up on it, but I'll now get it back again and try that.
look in device manager for the name of the device and then look that up on google, should tell you everything you need to know.
have you set your router to allow b connections? it may default to only allowing g connections.
does it still crash when using the older router?
