Title:
Qualcomm Atheros QCA6174 [168c:003e] subsystem: Killer 1535
[1a56:1535] WIFI stops working and system breaks
Status in linux package in Ubuntu:
Incomplete
Bug description:
I have a dell XPS 15 9570 laptop. I have been using Ubuntu (18, 19 and
20) for the last two years. Everything work fine except for the wifi,
which randomly stops working. Sometimes I can just turn off and on the
wifi and it comes to work until next random crash. However, other
times, when it happens, I cannot turn off wifi, it seems like the
system breaks, I have to hard shutdown the laptop and after boot it
works again.
