Some users find that disabling Wi-Fi on other devices helps. Updating your phone’s software and the adapter’s firmware can resolve many issues.
Maintaining Your Adapter These adapters are generally low maintenance. Keep the USB port clean and avoid pulling the cable. If the adapter gets hot, it may need ventilation.
