TP-Link Archer TX20E Troubleshooting Guide

Adapter is not detected

Turn off the computer and reseat the card. Try another compatible PCIe slot, then check Device Manager for an unknown network controller. Install the correct driver for the exact hardware revision and restart Windows.

Wi-Fi works but Bluetooth does not

Check that the internal four-pin Bluetooth cable is connected to both the adapter and a compatible motherboard USB header. In Device Manager, look for Bluetooth devices or an unknown USB device, then reinstall the Bluetooth driver if necessary.

Connection is slow or unstable

Move the antennas away from metal obstructions, place them upright, and test both frequency bands. The 5 GHz band generally provides higher throughput at shorter range, while 2.4 GHz may travel farther but can experience more interference. Restart the router and update its firmware when appropriate.

Unable to join a wireless network

Confirm the network password, temporarily remove and re-add the saved network, and verify that the router is using a supported security mode. Updating the adapter driver can also resolve compatibility problems.

Preventive measures and support

Keep the driver and Windows installation current, maintain clear antenna placement, and avoid placing the desktop beside sources of strong electrical interference. If problems continue, record the adapter hardware revision, Windows version, motherboard model, and any Device Manager error message before contacting TP-Link customer support through the official support and download section. Error codes can vary by Windows version, so use the displayed code when requesting assistance.
