Ubuntu – Wifi networks are not showing in Ubuntu 16.04

networkingwireless

Very recently I have made up my mind to use Ubuntu. Firstly installed the 14.10 version and that didn't go well. On that particular version the wireless network option was not visible. I couldn't turn on the wireless connections. After that I re-installed the 16.04 version, in which the option is showing that wireless network is there but no network is showing up. Any suggestion how to solve this problem?

Best Answer

This helped solve the problem for me.

sudo systemctl restart network-manager

or 

sudo service network-manager restart

I am still looking for a permanent solution, but this solves the issue till restart.

Update

Suffered from similar symptoms again. I had a stable 16.04 running smoothly for months and then suddenly yesterday the WiFi just stopped working. No networks would show on the nm applet. Tried quite a few suggestions (including my own) and none worked.

Finally realized that my last upgrade didn't go too well and had crashed in between. Removed the dkpg locks and ran sudo apt-get upgrade. A reboot later, all was back to normal.

sudo rm /var/lib/apt/lists/lock
sudo rm /var/cache/apt/archives/lock
sudo rm /var/lib/dpkg/lock

Ubuntu network manager seems quite fragile!
