[SOLVED] Lost network icon & internet access
« on: April 25, 2019, 05:23:11 pm »
After a 4.18 kernel upgrade yesterday I lost the network icon as well as internet access, WiFi is gone.
When I connect the ethernet cable it does not get detected either. I had installed GParted but funnily enough it does not launch anymore.
I have Mint 19.1 XFCE is dual boot with Windows. Before the problem I could see all the Windows files (NTFS), now I can't anymore; a USB stick is not detected.
Some other things that have disappeared and that I am discovering bit by bit:
* Synaptic
* Rubbish bin

I tried
Code: [Select]
sudo service network-manager stop
rm /var/lib/NetworkManager/NetworkManager.state
service network-manager restart

No result.
I cannot believe I have to do a fresh reinstallation. The computer is working fine in that I have access to my files and can use them. When I use the live USB stick the network is visible & works fine, Wifi included.
Any suggestions?

Here is a print-out of inxi -Fxz:

Have you tried booting the earlier kernel ?

Yes, it did not work. I reinstalled Mint.
