firstly mediatek is one of those vendors having odd hardware support on linux over the years, but its getting better since recently.
- support for mediatek wireless cards were supposedly finalized in kernel 5.18. make sure you are atleast running kernel 5.18 or later best is to run the latest LTS; 6.1
- if BT is listed as soft-blocked under
rfkillthen you should be able to enable it with;
$ sudo rfkill unblock bluetooth
- wanting wireless devices enabled (not enabled by default), can be done by explicitly setting TLP settings in
/etc/tlp.conf. locate
#DEVICES_TO_ENABLE_ON_STARTUP="wifi"
and change it to
DEVICES_TO_ENABLE_ON_STARTUP="wifi bluetooth"
Restart TLP and the bluetooth service.
- what you didnt mention was that this is possibly a laptop having internal wireless card and you are having issues with a USB wireless card. in such cases detection, device firmware might need additional time to wake and standby for connections. cant you connect to the inbuilt bluetooth, seems to be readily available
