Mobile internet via cellular network mostly not working

[Anna]

A recent update seems to have brought an additional problem that prevents mobile Internet connections.

This can, however, apparently be fixed fairly easily; two solutions are described in the thread DNS Problems with Mobile Data .

What worked for me was the solution by Zebulon Walton as summarised by arno_nuehm:

Code:

sudo apt install resolvconf

sudo nano /etc/resolvconf/resolv.conf.d/head

In that Document add the line

Code:

nameserver 9.9.9.9

(or "nameserver 1.1.1.1" or whichever DNS server you like) at the bottom of the text. Then save, close and go:

Code:

sudo systemctl restart resolvconf.service

sudo systemctl restart systemd-resolved.service

That's all.

Any sustainable solutions to the other problems are still welcome.
