- restart Bluetooth and the device you are pairing
- remove the device from Settings and pair it again
- check Device Manager for a disabled or warning-marked adapter
- install the newest Bluetooth driver from the PC maker if the problem started after an update
- use the stronger reset, reinstall, or cache rebuild steps only for the exact failing feature
