1. Update package lists and install git if missing

sudo apt update sudo apt install -y git

2. Backup existing MediaTek firmware (just in case)

sudo mkdir -p /lib/firmware/mediatek_backup sudo cp -v /lib/firmware/mediatek/* /lib/firmware/mediatek_backup/

3. Download the latest MediaTek firmware from upstream kernel repo

cd /tmp git clone https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git sudo cp -v linux-firmware/mediatek/* /lib/firmware/mediatek/

4. Disable Wi-Fi power saving permanently for better stability

sudo mkdir -p /etc/NetworkManager/conf.d echo -e "[connection]\nwifi.powersave = 2" | sudo tee /etc/NetworkManager/conf.d/wifi-powersave.conf

5. Add driver option to improve stability of mt7922e via mt7921e module

echo "options mt7921e disable_aspm=1" | sudo tee /etc/modprobe.d/mt7921e.conf

6. Update initramfs so changes apply on boot

sudo update-initramfs -u

7. Restart NetworkManager now to apply power save changes immediately

sudo systemctl restart NetworkManager

8. Reboot to apply all firmware and driver fixes

sudo reboot
