Hi, thanks for the update.

It is suggested to test the driver here to see whether it helps:

Realtek Chipset Driver for Archer T2U(Nano/ Plus)/T3U(Nano/ Plus)/T4U(Plus)/T4UH/T9UH (Win7/Win10)

 

How about other mobile devices at home? How much of their 5GHz WiFi speed?

Could you please also refer to this link to help me check the current WiFi link speed:How to check the associated/link speed on a wireless client

 

You can also refer to this link to find more suggestions:How to improve the speed of TP-Link wireless adapters

 

Thank you very much.

Best regards.

Hi, is the 5GHz wifi also ~2mbps?

Have you tried to set the 5Ghz channel to channel 48 on the host router?

Please also test the driver here to see whether it helped:https://community.tp-link.com/en/home/forum/topic/509006

 

By the way, how long have you had the adapter?

Wait for your reply.

Best regards.
