@TheRedBull, good you figured it out! I have been using a USB dongle for my internet (capped at 100Mbit though, my Ethernet is 240Mbit) ever since. I did a new try yesterday and I still couldn't install the network drivers. The network interface is populated but I don't get a IP address over DHCP. Adding the IP address manually doesn't work either. I just gave up. The USB dongle is working fine.
