AR9485 - Kubuntu (Ubuntu 14.04.1 LTS) wireless not connecting anymore

Question

I'm running Kubuntu 14.04.1 LTS on a Asus PU301LA RO039G. Wireless and wired connection worked fine until yesterday, when the "I don't know what" happened. Symptom is the unability to connect to my home WPA2 password protected wireless network (ASUS RT-N14U router wireless n300). Network is detected but, clicking to connect, it remains stucked to "Waiting for authorization" stage, prompting a password request continuously. The other wireless devices just connect fine. The wired connection works fine. I tried to disable kwallet, to remove kwallet and network manager configuration files, without improvement. I tried both network-manager and wicd with same result (like the password was incorrect). I noticed in dmesg some "country code" messing up between authentication and deauthentication time.

The driver in use is:

I don't know what other system information outputs to post, but if someone can help I will grab any further useful informations later.

Thanks in advance.

Please run the script and post the file from the router you are having trouble connecting too. Please add all script information to your question and delete it as an answer. Thanks — Wild Man, Aug 16 '14 at 02:22
Hi, some recent updating: some days ago suddenly the laptop started to connect also to home router, after kwallet password request and a period of time in which the wireless card seems to grab no wifi signals. So, for now, the problem is solved by itself (although the behavior is barely weird). So, let me know if I have to delete the whole question or add script information anyway. Thanks! — riotste, Aug 24 '14 at 11:59

Do:

sudo ifconfig wlan0 down
sudo modprobe -rv ath9k
sudo modprobe -v ath9k nohwcrypt=1
sudo ifconfig wlan0 up

the settings will be lost after you reboot, so if it helps we will need to make it permanent.

Thanks for your answer Wild Man, but the procedure had no effect. I also tried to reset the modem and the router, but nothing changed. – riotste Aug 03 '14 at 21:22
Please run the script that is in the accepted answer in the link below so we may see the information needed to help diagnose the issue. http://askubuntu.com/questions/425155/my-wireless-wifi-connection-does-not-work-what-can-i-do – Wild Man Aug 03 '14 at 22:29
Hi, sorry for the delay in the answer but I've been in Italy for a while. I noticed no problem with the wireless network at my parents home, connection was just automatic and always fine (router TP-LINK, I don't remember the model but if you think it is useful I can ask). I also noticed no problem with the wireless router in my workplace (Serbia, where I am now). Moreover, yesterday I tried to reset the home cable modem to which the wifi router is attached and after setting back up wifi infos, the laptop connected. I will post wireless_script output from here and, if you need, also from home. – riotste Aug 14 '14 at 10:46
