RTL8811AU 802.11a/b/g/n/ac WLAN Adapter There is no mainline or staging kernel module for it, so i get it from: https://github.com/aircrack-ng/rtl8812au I stick to using the 5.3.4 branch. The main issue is random system freezes that lead to reboots. In the journal there is not indication of what its wrong, i even set up kdump since the freeze lasts around 90 sec before the reboot, but no dumps are created when it happens. It also happens with the vanilla kernel. This led me to believe is a faulty hardware. So i got a new one. The new device, same chip, has the same issue so i tested it in another system where i get the same results. No issues on windows 7 or 10, neither on KDE Neon. I noticed the problem occurred when i was doing some heavy? use of the network, streaming videos, torrenting stuff. Shooting in the dark since i have little knowledge on how to debug this kind of problems i ran: iwconfig DEV frag 768 After that i did notice the freezes and reboots are less common and i managed to get some info (see attachment) on what it may be going on. -- You are receiving this mail because: You are on the CC list for the bug.
