If the LED on your TP-Link Archer T3U AC1300 Mini Wireless MU-MIMO USB Adapter is off, you can follow these troubleshooting tips to check if the adapter is recognized and enabled on your computer:

1. **Check Connection:** Ensure that the adapter is securely connected to a USB port on your computer. Try using a different USB port on the computer to rule out any port-related issues.

2. **System Requirements:** Make sure your computer meets the minimum system requirements for the adapter as specified in the product documentation. Also, ensure that your computer has the latest Windows updates installed.

3. **Driver Installation:** Verify that you have installed the latest driver for your specific adapter. You can download the driver from the TP-Link website at https://www.tp-link.com/download-cent...

4. **Device Manager Check:**

- Right-click on the Computer icon on your desktop and select "Manage."

- In the Computer Management window, navigate to Device Manager.

- Look for the TP-Link adapter under the Network Adapters section. If you see the adapter listed without any warning symbols, it indicates that the device is recognized and enabled.

5. **Antivirus and Firewall:** Temporarily disable your antivirus software and firewall, as they might be blocking the adapter's functionality. After disabling them, reconnect the adapter and check if the LED turns on.

6. **Restart Computer:** Try restarting your computer after performing the above steps to see if the adapter is recognized and enabled upon reboot.

If you have followed these steps and the LED on the adapter is still off, consider reaching out to TP-Link Technical Support for further assistance.
