My work laptop at my office constantly does this. Like at this very moment I am receiving 'excellent' signal strength according to my wireless utility, but I can not connect to the wireless network. I have talked to my systems department but they have no answer as to why I can not connect. According to them all my settings are correct for our office network.
Maybe I'm off base here, but if I can see it, shouldn't I be able to connect to it?
