I am using it Archer T4U V3 USB adapter for one month. it worked good. Sometimes wifi got disconnected.

Today when I woke up I found out that the adapter is not detecting 5GHz WiFi hotspot.
I have checked & done everything possible.
Other WiFi adapters are detecting 5GHz hotspot.


So the conclusion is the 5GHz band of Archer T4U is dead.

Currently using 2.4GHz band for connecting to WiFi hotspot.

When did the V3 come out? You sure it's a v3? Lol anyways, all TP-Link Archer T-models I know of use the RTL8812AU chip, and you can get my repacked unofficial driver here: http://forum.tp-link.com/showthread.php?101991-Archer-T4UH-V1-T4UH-V2-T9UH-Driver-Unofficial-Version-171121-Windows-32-and-64-bit

Good luck! :D
