I'm connecting to a wireless network with "WPA & WPA2 Enterprise" security and "Protected EAP" authentication, and it requires a user id and password. When I first set up this connection (fresh, like I've never connected to it before), I can connect fine. However, after rebooting and attempting to connect again, I get the "Authentication Required by wireless network" dialog prompting for user id and password, which I enter, click Connect, but it fails and shows the same prompt. I can keep trying, but it will continue to fail until I "forget" that wireless network and re-add it. Once I do that, it connects fine.

Simply "disconnecting" (not rebooting) allows me to reconnect to the network without issues.

If anyone has any ideas, I would be very glad to hear them.
