Title:
10ec:818b [Lenovo ThinkPad T440] WiFi does not reconnect after
resuming from sleep in Ubuntu 14.10
Status in linux package in Ubuntu:
Incomplete
Bug description:
After resuming from suspend via closing the lid, my wireless doesn't
work. It finds the wireless network and tries to reconnect but fails.
The only I can solve it now is by restarting. This happens with both
my home and university AP. I do not have any other problem with these
APs with my other laptop.
I tried to re-initialize the kernel module but it doesn't work as per dmesg:
modprobe -r r8192ee && modprobe r8192ee
