- Ensure the adapter is properly inserted into a USB port. Check if the WiFi signal light is on. Verify that your computer's Wi-Fi is enabled in network settings. Try plugging the adapter into a different USB port.
- Slow connection speed:
- Ensure you are connected to the 5GHz band for higher speeds, if available. Check for interference from other devices. Ensure your router supports WiFi 6 and is configured correctly. Move closer to your Wi-Fi router to improve signal strength.
- Adapter not recognized (no driver installation):
- Although driver-free, ensure your Windows 10/11 operating system is up to date. Try restarting your computer after inserting the adapter. If issues persist, manually check Device Manager for unrecognized devices and attempt to update drivers through Windows Update.
- Intermittent connection:
- Check for physical obstructions or sources of interference. Ensure the adapter is not overheating. Update your router's firmware if possible.
