  • Try another USB port (avoid USB 3.0 hubs – this chip is USB 2.0 only)
  • Check power – some dongles need more current → use powered USB hub
  • Test on old OS (Win7 or Ubuntu 18.04) to confirm hardware works
  • Replace hardware – CTWN4320Z is ~$2. A modern RTL8812AU (ac1200) dongle costs $10 and has official drivers
