Following a routine update to Ubuntu 12.04, my wireless no longer works - it is constantly seeking a connection but not accepting my password.
This has been documented elsewhere, with a fix involving file creation:
options ath9k nohwcrypt=1
followed by reboot.
However, I have tried this fix with no success, and I can't find any other solutions.
This using 12.04.1 32-bit on an Acer D270-26Dkk.
Can anyone help?
