XPS 9350 Thunderbolt Display issue when connected to 802.11 2.4GHz
When I have my WiFi connected to a 2.4GHz wireless router my display (connected to Thunderbolt 3 StarTech HDMI connector) disconnects frequently. Both the monitor connected to the Thunderbolt 3 and the laptop monitor flash 2-3 times and then comes back and starts working again. And then it repeats again minutes later... and again... and again
If I change to a 5GHz wireless router... then everything works great.
