Wifi Stopped Working - Mint 17.1

[mattcuk]

Hi,

I recently performed a clean installation of Mint 17. After installation the Wifi did work but it wasn't 100% (would drop now and then) but always could connect.

I installed network-manager-openvpn http://community.linuxmint.com/software ... er-openvpn and shortly after my Wifi disconnected and from that point on I haven't been able to reconnect. I've since removed network-manager-openvpn and that hasn't fixed it. I'm not sure how to best go about diagnosing the problem.

If I try to connect to a network and hover over the spinning network symbol it says " Configuring Wi-Fi network connection 'my network' " then the spinning stops and I get a disconnected notification pop up. The Ethernet connection still works absolutely fine.

I ran mintWifi.py as recommended:

I'm using a Sony Vaio Laptop (VPCEB4E4E) Dual Core i5. If I could have advice as to how to fix this issue and get my Wifi working again that would be great!

Thanks in Advance,

Same story . but look like nobody knows what to do...

Recommended settings for wireless would be to have IPv6 set to ignore in Network Manager and router encryption set to WPA2-AES only, no WEP or TKIP
Not a lot of parameter options but one that could be tried is

Code: Select all

sudo modprobe -r ath9k

Code: Select all

sudo modprobe ath9k nowcrypt=1
