Model: Archer T4U  
Hardware Version: V1
Firmware Version:

@Kevin_Z @Kathy_Z  Please help me provide a driver for my old t4u v1. I got problem when connected to my Archer C6 (EU) 5ghz. It will auto disconnect every a few minute but not 2.4ghz. I use windows 10 64 bit OS. My driver for this adapter which is windows auto install is (refer screenshot), and 1 more thing I don't have any disconnection on other devices such as my phone and my desktop pci-e card (Intel ax200). Maybe this device a bit old, but I think its driver issue.

Hi, it seems you are already running the latest public driver for the T4U adapter.

 

When did this issue happen? Have you ever updated the Windows 10 system? BTW, please check the Windows 10 version: https://www.tp-link.com/support/faq/2722/.

Have you tried to change the router’s 5G channel, like channel 36/44/48, channel width to 40MHz?

When the connection dropped, were you still connected but no internet or the Wi-Fi has been disconnected already?

Moreover, would there be any error message when the connection dropped?

@Kevin_Z yeah I got latest windows 10.

I changed the channel and width still same, when the connection dropped, my Wi-Fi has been disconnected completely and take about 20-30 seconds to reconnect successfully. It's annoying because this happen only on 5ghz, while 2.4ghz is fine (on this adapter).  I think its not my router problem because other devices and my ax200 pci-e card not having any disconnection on 5ghz. Btw, my driver already latest? Coz it directly from Microsoft (auto install), can you provide link for latest driver from Tp-Link so I can manually install it because on TP-Link site https://www.tp-link.com/en/support/download/archer-t4u/v1/#Driver the driver so old.

Yes, here is the latest public driver:

https://static.tp-link.com/2020/202006/20200601/00015960-RTLWlanU_WindowsDriver_1030.38.0712.2019_Drv_3.00.0032.L.zip

 

Please check on the network adapters and see how many drivers have you installed for this adapter, if there are different drivers, remove all of them and install it from the Windows. Then install the driver manually:
