I have a E495 Lenovo that came with rtl8822be wifi/bt combo. The bt there stopped working randomly. I did upgrade manjaro firmware around the same time, but I am not sure that is the case. I tried a lot of things but nothing worked. inxi -n didn’t even show the card, but atleast lspci showed that i have the card and WiFi worked. Now i bought the AX200 and WiFi still works and inxi -n finally shows the card, but bluetooth is still dead. bluetoothctl can’t find any adapters. bluetooth.service is running happily and I am here just dead in the water. Any suggestions?
EDIT: I have a similar post here where i talk about RTL8822BE and what i tried to do.
