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 didnāt 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 canāt 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.
and post some more information so we can see whatās really going on. Now we know the symptom of the disease, but we need some more probing to know where the origin liesā¦
An inxi --admin --verbosity=7 --filter --no-host and an rfkill list would be the minimum required informationā¦ (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)
P.S. If you enter a bit more details in your profile, we can also see which Desktop Environment youāre using, which CPU/GPU you have, ā¦
Thanks for the response. At the moment I fixed my problems by reinstalling Manjaro and I am using 5.4 LTS kernel currently and that seems to be working correctly currently. If the Bluetooth disappears again I will be back for help
