Post-Reinstall Setup for Wi-Fi & Bluetooth ASUS PCE-AX3000 (Intel AX200 chipset)

1. Enable Wi-Fi Support

  • Make sure your kernel is version 5.1+: 
    uname -r

    If older, consider upgrading via backports or using a newer Debian release.

  • Install the Intel Wi-Fi firmware: 
    sudo apt update
sudo apt install firmware-iwlwifi
  • Reboot or reload the driver: 
    sudo modprobe -r iwlwifi
sudo modprobe iwlwifi

🔗 2. Get Bluetooth Working

The AX200’s Bluetooth runs over a USB header cable, so make sure that little cable is plugged into your motherboard!

  • Install Bluetooth-related packages: 
    sudo apt install bluetooth bluez bluez-firmware
  • Optional but helpful: Prevent USB autosuspend (can cause issues) 
    echo 'options btusb enable_autosuspend=0' | sudo tee /etc/modprobe.d/btusb.conf
  • Reboot to apply everything.

🔧 3. Troubleshooting Bluetooth (Only If Needed)

If bluetoothctl still says No default controller available, try:

  • Reinstall firmware: 
    sudo apt install firmware-intel-sound
  • Manually reload Bluetooth module: 
    sudo modprobe -r btusb
sudo modprobe btusb
  • Check logs for firmware loading: 
    dmesg | grep -iE 'firmware|btusb|hci'
