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:


with contents:

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?

even if this folder doesn't exist, you may create it.
