Hello everyone,
I have a problem with a conflict between a 4G connection and an ethernet connection.
When I use only the 4G connection, everything is fine, but as soon as I active the ethernet link, my 4G connection keeps disconnecting/reconnecting until it does not reconnect anymore.
I have been on that subject for days, so any help/idea would be very much appreciated.
Here is my log from journalctl (that sequence is repeated about every minute) :For information, here is what I get with ip route :And my configurations nmcli for my 2 connections :
