My computer was just able to connect a minute ago but after I restarted it can find WiFi signals and knows the password but won't connect. It's within range of the WiFi signal, but simply refuses to connect. Let me know of any additional info you might need. Thanks for any help.

My WiFi just connected right after I entered these commands. Can you tell whether or not my connectivity will still be unstable?

lspci | grep network gives me no output

Please, edit your post and add the following output: lspci | grep network, iwconfig and nm-tool. – Braiam Aug 6 '13 at 2:14

Run the commands one line at a time, just copy and paste for accuracy, it usually gets this driver to connect better. You only have one network with a strong enough signal to connect too, and it is barely strong enough, it is myqwest0382 so I hope that is the network you are trying to connect too.

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

sudo modprobe -rfv ath9k

sudo modprobe -v ath9k

The signal I'm trying to connect to is "exiga"which shows a higher strength than the one you said, if the higher the strength value shown is the stronger the strength of the signal. It just doesn't make sense why the signal would start to get screwy on me now. – Paul Ronquillo Aug 6 '13 at 7:45
I see that now that code blocks have been added. Did the commands help? If not were there any errors? Also it is usually best to have the routers encryption set to just wpa/2 if you have that option. – Wild Man Aug 6 '13 at 14:00
