I have Dell Precision M6400 with an Intel Wireless WiFi Link 5100. Under F11 the wireless worked flawlessly with Network Manager, but now under F12 is giving me problems. F12 recognizes the card and when I first boot, the NetworkManager Applet sees the wireless network I'm trying to connect to as available, but when I try to connect to it I get the message on the wpa_supplicant.log below, and then that wireless network does not show up again as available until I reboot the computer.
Failed to initiate AP scan.
Trying to associate with 00:14:f2:70:d8:b0 (SSID='bgsu' freq=2412 MHz)
CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys
Authentication with 00:00:00:00:00:00 timed out.
Any help figuring out this problem would be greatly appreciated.
