Public bug reported:
I've found a quite easy-to-reproduce bug (provided you have a Ralink
RT2860 wireless card). On a fresh boot, I am unable to connect to an
encrypted wireless connection (WPA2), if I'm on battery power. Attached
in the dmesg is things I don't quite understand, but they're probably
helpful to somebody. If there is other information I can provide, let
me know.
Steps to reproduce:
1) Remove power plug from netbook (run it on battery)
2) Boot laptop, log in,
3) Attempt to connect to WPA2 encrypted wireless
4) Provide correct credentials to nm-applet dialog box asking for encryption key
5) Wait about 30 seconds
6) Repeat steps 4-6 until you give up and plug in, reboot.
I did try this while connecting to open wireless (no security) while
doing the same steps as above, and was able to connect fine.
