EDIT
The problem also exists on my other laptop, which has a different ethernet card. I assume the problem isn't Ubuntu per se.
Noteworthy though is that internet with Ubuntu works at my other home. And internet here works on both laptops booting Windows.
This problem becomes more complicated each time I come closer to a solution. Anybody has an idea what could be causing this strange behavior?
Problem
Wireless: I am connected to my home network, everything works fine for 30 seconds but shortly after the connection drops with the following error in chrome:
server DNS address could not be found.
Try:
Checking the proxy, firewall, and DNS configuration
DNS_PROBE_FINISHED_BAD_CONFIG
When I re-connect it works again for about 30 seconds, this is an infinite cycle.
LAN: At first my wired connection wasn't working at all. After a lot of googling I got it to work with this code from the following thread: LAN not working on 17.04
sudo touch /etc/NetworkManager/conf.d/10-globally-managed-devices.conf
sudo service network-manager restart
However the wired connection now has the same issue as wireless. It also stops working after a short time with the same error in chrome. However, with the wired connection I can still visit, and browse through all pages of websites I've loaded in the same session. This leads me to the conclusion that new DNS'es simply stop working after a given time.
