T3U Archer only connecting at USB 2.0 speed

Tags: #Windows 11

Model: Archer T4U Plus

Hardware Version: V1

Firmware Version:

I'm using a T3U ARcher wifi adapter on my Win11 pc but I am receiving a "Device can perform faster when connected to USB 3.0" warning in my Devices settings.

I know it's not an issue with the port (have tried all 3.0 ports on my PC and they work with other USB 3.0 devices correctly) and I have updated to the latest drivers. I have the wireless mode set to IEEE 802.11ac, however it still caps out at 400Mbps when connected.

Any guidance how I can get this to operate at full speed? Thanks

Hi, Could you please refer to this link to help me check the current link speed on Archer T3U:

How to check the associated/link speed on a wireless client

The maximum link speed for Archer T3U on 5ghz is 866m/s, 400m/s(about 46% of the link speed) via speed test is quite expected due to the distance and wifi interference.

Thank you very much.

Best regards.
