Fix

git clone https://github.com/discipleartem/mediatek-mt7902-linux-wifi-bluetooth.git
cd mediatek-mt7902-linux-wifi-bluetooth
./tests/run-tests.sh
sudo apt install -y build-essential linux-headers-$(uname -r) git dkms
sudo ./mt7902.sh install-all && sudo reboot
./mt7902.sh verify

Installs mt7902e + btusb_mt7902, firmware, modules-load.d autoload, shutdown helpers, and mt7902-watchdog (reloads modules if Wi‑Fi/BT drop). Rollback: sudo ./mt7902.sh rollback.

Details: docs/installation.md · FAQ: docs/faq.md.

Known limitation

Bluetooth install blacklists btusb and btmtk. Built-in MT7902 BT works; a Realtek USB Bluetooth dongle via stock btusb will stop. See docs/faq.md.
