Hey there,
my wifi crashes after sometime, however if i turn fligthmode on and off it works again for a few minutes. So i thought, it maybe that wifi is going into powersafe but not starting again properly. I have tried deleting all the old kernels, reinstalling the rtl8822be (wificard) drivers and using tlp to disable wifi-powersafe. Still didnt manage to fix it.
If someone can help, it would be much appreciated.
All the best
Jakob
