I'm running Ubuntu 14.04 on lenovo yoga 13. Previously my wireless was working correctly, but only after running a script to fix the wireless:
cd /opt/rtl8723au-master make clean make sudo make install sudo modprobe 8723au
This no longer works though. I recently had an update for a new kernel version. After updating I can no longer use the above script to connect to wireless. The script now eventually returns:
Module 8723au not found
lo no wireless extensions
lspci -vvnn | grep Network:
Nothing is returned
Linux "computer-name" 3.13.0-43-generic #72-Ubuntu SMP Mon Dec 8 19:35:06 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
Also I would like to note this laptop does not have an ethernet port so I cannot connect to the internet at all.
If anyone has any suggestions that would be greatly appreciated, or if you need more info from me just let me know.
