Realtek RTL8852BE intermittent issues

[Arrababiski]

When there are glitches with wifi connection, first try disabling powersave and Mac randomization.

RTL8822CE Instability even with newest kernel

You can try two workarounds. Turn off wifi power save first. Create .conf file: sudo nano /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf And copy these two lines inside it: [connection] wifi.powersave = 2 If the issue remains, turn off Mac Randomization. Create .conf file: sudo nano /etc/NetworkManager/conf.d/disable-random-mac.conf Copy these two lines inside: [device] wifi.scan-rand-mac-address=no Hope this can solve your problem.
