My wi-fi stopped working. I used to have this problem from time to time and
service network-manager restart was always enough to fix it, but after system update the wi-fi doesn't work at all even after reboot.
The network manager doesn't see any posible wi-fi connections.
I tried this to repair it: How can I fix Networking, Wi-Fi and Ethernet, not being available after update? but it didn't help. I assume it is similar problem, but the solution is for older versions. Can you pleas help me to repair my wi-fi again? The internet connection via ethernet works fine.
