I'm able to connect again as well, though I did try what AussieMacbook tried too before reading what wifiguru posted. I uninstalled the current drivers with device manager, and then reinstalled bootcamp 5.0.5033 drivers. It only seemed to work after 3 restarts in my case. I didnt actually get a chance to try unplugging and having it in a shut down state for 5 minutes, as the problem seemed to have been solved before then. I should also note that the exact same strange symptom of the computer hanging/freezing occurred to me as well, and after a couple more restarts past that point with the device driver reinstall, my issue was solved. Weird that we both had that frozen symptom...
So for anyone else having this issue, try what wifiguru said first:
Shut down, wait 5 minutes, then reboot.
If that doesn't help, then try:
Uninstalling the Broadcom wireless AC drivers in Device Manager, restart the mac, install bootcamp drivers again (and it will repair the wireless ones), and then try restarting a couple times.
Cheers!
