This is a hardware specific issue with Ubuntu 18.04 and kernel 4.15.0-20-generic. The driver for the Intel AC 9560 wireless chip causes the problem. Driver location: https://www.intel.com/content/www/us/en/support/articles/000005511/network-and-i-o/wireless-networking.html

The wifi connection is very slow (1MB instead of 100MB possible) and is also very unreliable.

When installing the 4.16 kernel from mainline kernel http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.16/ the described problem is solved.
