My Yoga stopped connecting to the WiFi network.
I did everything as described in this answer by rubo77: Ubuntu on Lenovo Yoga 2 Pro
sudo rmmod ideapad_laptop
sudo service network-manager restart
It worked like a charm for a couple of weeks. Then yesterday I suddenly was not able to connect to the wifi (although the network manager shows all the available networks).
I tried restarting the network-manager. The ideapad_laptop mod is not active.
Where to look now to resolve this issue?
