Hello @vore ,

Thanks for contacting our community.

For your case, here are some suggestions that may help you:

1. Test your network stability: Connect another device to the same Wi-Fi network. If that device also has an unstable connection, the issue may be with your router. In this case, please contact your router manufacturer for further assistance.
2. Disable your computer's built-in Wi-Fi adapter: If your computer has a built-in Wi-Fi adapter, disable it to prevent interference with your TP-Link adapter.
3. Improve signal strength: Move your adapter closer to your router (ideally within 10-15 feet) to ensure a stronger signal.
4. Check power-saving settings: Power-saving mode can cause disconnections. Make sure it is disabled in Device Manager.
5. Update your driver: Download and install the latest driver for your adapter.

For detailed instructions, please refer to Case 2 on this FAQ: What should I do if the TP-Link network adapter is not working properly in my computer?
