Dear all. I am facing a bit of a strange issue:
Wifi is sometimes not working when using a Manjaro notebook plugged-in an external screen (via USB-C/Thunderbolt3 that serves as well for supplying power).
For now I am unable to determine when exactly the issue is appearing, it often happens often when connecting a running notebook computer but disconnects as well after it has been connected for several hours. Once the computer is disconnected from the screen, it captures again Wifi signal.
Often (but not always) when the connection is cut Wifi indicator turns into a question mark.
MY system is an up-to-date Manjaro Gnome. My notebook computer is a Lenovo T480s, the screen is a Dell p2720dc. But the problem already appeared on the predecessor model (T470s) with the same screen. All firmware is up to date. The issue is not related to unavailable internet.
I am facing this issue already for several months. It took me some time to figure out that is not related to a bad internet connection at all. For the moment it is really a big annoyment.
May this be a driver issue?
Is there anyone out there with a guess or even a pathway for a solution?
Thanks in advance.
