I have this reproducible issue on an XPS 7590(using a Killer 1650) that when I do somehting GPU heavy, e.g. gaming, the Wifi connection will get super flaky and then stop completley. DMESG is flooded with error messages regarding wifi. I only realized this, that the Steam client has a little notification which would tell you that you went offline. I started to experiment and it works for me if I disable the 11n standard. The driver has an option to do so (modprobe -r iwlwifi && modprobe iwlwifi 11n_disable=1). Only then I can play games and have an internet connection... I am pretty sure that if this would happen on Windows, all the users would have gone balastic.
