I had some issues with WiFi with my Lenovo y580, I could connect my home WiFi but it would disonnect me after few minutes and I wasn't able to reconnect I have Ubuntu 12.04 and I believe my network card is "AR8161 Gigabit Ethernet"
Changes I have been doing before it stopped working at all:
191 lspci -vv | grep Atheros
192 sudo apt-get install build-essential linux-headers-generic linux-headers-`uname -r`
193 wget -O- http://linuxwireless.org/download/compat-wireless-2.6/compat-wireless-2012-07-03-pc.tar.bz2 | tar -xj
194 cd compat-wireless-2012-07-03-pc
195 ./scripts/driver-select alx
196 make
197 sudo make install
198 sudo modprobe alx
It would be great if I could revert this change so ubuntu would use the previous standard driver.
Then I could at least connect to some WiFi and maybe this problem was router's issue and not my network driver one
Thanks for any help
