My wifi connection is not working, LAN connection works normally. The Wifi GUI offers me Bluetooth settings, which I believe is a remainder of previously shared bluetooth internet connection (via my phone).

My laptop is Thinkpad E595 running Ubuntu 22.04.

Is there a way to try to reinstall wifi drivers? Does this seem to be a HW problem?

EDIT:

Wifi HW information:
Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTL8822BE 802.11a/b/g/n/ac WiFi adapter
    Subsystem: Lenovo ThinkPad E595
    Physical Slot: 0

I have tried to install several drivers, so some should be removed?

I think that the main problem now is the unassigned class of the wifi HW? I have not found any way to repair that so far.

first solution is to backup your system and do a fresh install. do not touch the driver files unless needing an update.

the 2nd solution is go Software & Updates > Additional Drivers > then your wifi driver.

you should use an ethernet connection to download the drivers.
