Eeeh. Just click remember password? –  Melon Mar 3 '13 at 18:28
Yeah its saved and will stay connected for a little while but ask for password again. –  24hrEnErGy Mar 3 '13 at 19:29
Hm. Do you use torrent? I had similar thing. My WiFi router got down any time I downloaded torrents. Maybe it's the same thing here? –  Melon Mar 3 '13 at 21:46
No trorrent, pretty much just the default install package. Anyone know where all controls the wifi by default and where logs are kept. –  24hrEnErGy Mar 3 '13 at 23:18

Seems to be a duplicate of Network manager asks for wireless password continually

You might find it useful to set the connection as "available to all users", or remove duplicate connection configs for the same wifi

also, it's probably related to this known bug

This usually fixing that issue with your device it changes the encryption from hardware to software.

Run the commands one line at a time, just copy and paste for accuracy.

echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9k.conf

sudo modprobe -rfv ath9k

sudo modprobe -v ath9k

Not tried this, but do you have any reference for this? thanks –  dashesy Dec 5 '13 at 19:29

I know it sounds strange but I have the experience that in a case like this it might help to reboot your router.

Also check if the packet "wpasupplicant" is installed.
