TP-Link Archer T4E Troubleshooting Guide

Wi-Fi adapter is not detected

Turn off the computer and reseat the card in the PCIe slot. Check that the slot is enabled in the motherboard firmware and inspect Device Manager for an unknown network device. Install the driver matching the exact hardware revision rather than relying on an incompatible package.

Slow wireless speed or unstable connection

Use the 5 GHz network when the computer is near the router and the 2.4 GHz network when greater range is needed. Move the antennas away from metal obstructions, reduce interference from nearby wireless equipment, and update both the adapter driver and router firmware. Remember that the AC1200 rating describes combined theoretical band rates, not a guaranteed internet speed.

Bluetooth is missing

Confirm that the supplied internal USB cable is connected at both ends. Check Windows Device Manager for a Bluetooth category, reinstall the Bluetooth driver, and restart the computer. Remove an old pairing before attempting to pair the accessory again.

Installation or driver error

If Windows reports that the driver cannot start, uninstall the failed device from Device Manager, restart the computer, and install the correct driver for the adapter revision. Avoid manually mixing Wi-Fi and Bluetooth drivers from different revisions.

Getting additional support

For manuals, driver downloads, compatibility information, replacement guidance, and warranty assistance, use the TP-Link Support website and select the Archer T4E hardware revision shown on the product label. Keep the model number, hardware version, operating-system version, and a description of the problem available when contacting TP-Link support.
