Network manager error

Since last night my internet connection has been disconnecting randomly. Sometines it is up for a couple of hours, sometimes it disconnects after being online only for 5 minutes.

Here is my journalctl:

I have no clue how to begin solving this problem. Any ideas?

Re: Network manager error

To be honest, I have no idea what the problem could be, but if I were you, I would first try to narrow down the problem. Could it be hardware related, e.g. network card, router, cable? If possible, connect wired and see if the problem persists. Did you install software updates? If yes, try to find out if there was something related to the network among the updates.
