If Windows does not detect the adapter, install or reinstall the driver before changing advanced network settings.

Troubleshooting Guide

Adapter is not detected

Try another USB port, restart Windows, and check Device Manager for an unknown network device. Remove older wireless-adapter drivers if they conflict, then install the current Archer TBE400UH driver for the correct hardware revision.

Wireless networks are missing

Move closer to the router, confirm that the router is broadcasting the required band, and check whether the computer supports the selected 6 GHz configuration. Some 6 GHz networks may not appear when regional, security, or router compatibility requirements are not met.

Connection is slow or unstable

Use the 5 GHz or 6 GHz band when nearby, reposition the adapter in an open area, update the router firmware, and reduce interference from crowded 2.4 GHz devices. Test with another USB port and compare performance using a local network transfer rather than an internet speed test alone.

Frequent disconnections

Disable USB selective suspend temporarily, update Windows and the adapter driver, and check the router’s channel and security settings. Avoid using a damaged hub or an underpowered USB extension.

Support options

For unresolved issues, consult the Archer TBE400UH user guide, driver-download page, hardware-version information, and TP-Link regional support center. Have the adapter model, hardware revision, Windows version, router model, and troubleshooting results available when contacting TP-Link support. Warranty coverage and service procedures vary by region.
