4. Operating the Adapter

6. Troubleshooting
6.1 Adapter Not Detected or Not Working
- Check USB Port: Ensure the adapter is securely plugged into a functioning USB port, preferably a USB 3.0 port. Try a different USB port.
- Driver Installation: Verify that the correct drivers for your operating system are installed. If you used the CD, consider downloading the latest drivers from the TP-Link website.
- Restart Computer: A simple restart can often resolve detection issues.
- Device Manager (Windows): Check Device Manager to see if the adapter is listed and if there are any error indicators (e.g., yellow exclamation mark). Reinstall drivers if necessary.
6.2 Slow Connection Speeds
- USB 3.0 Port: Ensure the adapter is connected to a USB 3.0 port. USB 2.0 ports will limit performance.

- Interference: Reduce interference by moving the adapter away from other electronic devices (e.g., microwaves, cordless phones) or physical obstructions.
- Router Placement: Ensure your wireless router is centrally located and not obstructed.
6.3 Frequent Disconnections
- Signal Strength: Check your Wi-Fi signal strength. Weak signals can lead to disconnections.
- Driver Stability: Ensure you have the latest stable drivers installed.
