I hoping someone can help, I have a very frustrating problem I can't resolve.
I've searched this forum along with other resources to no avail.
My problem is no wireless device is available after suspend.
The driver is rtl8723au and I'm using a Lenovo Yoga 11s
This problem did not exist with 14.04
Using syetemd to bounce network-manager does nothing, nor does nmcli - there is no device at all???
NB** To get wireless to work after a fresh install (not rolling upgrade) I have had to add the following to /etc/rc.local
Code:
rmmod rtl8xxxu && sudo modprobe rtl8xxxu
Attached is the output of the wireless-info script (whilst wireless is operational)
wireless-info.txt
Inline also in case the attachment doesn't work
Help would be greatly appreciated.
Code:
