Model: Archer T4U
Hardware Version: V3
Firmware Version: Archer T4U(US)_V3_181023_Win

OS: Windows 10 2004.

 

Simple... Most times the adapter will keep disconnecting (making sounds of USB connected/disconnected) if I select a 5GHz Network... From other search I've discovered that one of the problems is because this driver (on TP-LINK's website) is too "old" and windows keep trying to use a "newer" one. If I try to update the driver to the correct one (downloaded from TP-Link), sometimes the adapter will freeze, or keep restarting, or switch back to the default driver. So I have to unplug, replug, update driver again until it finally works.

The other problem is that sometimes I'll suspend or leave my PC unattended for some time, and then the connection is lost and I have to try my luck again with the cycle described above. I can't believe there's been 2 years since last driver update, because it's pretty obvious these won't work for 5GHz at all (various reports)... It doesn't even work properly for 2.4GHz because the connection is spotty (stuttering) if using the default driver.

@Rehv 

Good day.

Thank you very much for your time and patience.

May I know how long have you had the adapter and when did the issue start?

Have you tried to update the following driver;(ForT3U/T4U)

https://static.tp-link.com/2019/201911/20191128/Archer T3U_beta_U2_U3_5G unstable issue_1030.22.0202.2018.zip

 

(how to update the driverhttps://www.tp-link.com/support/faq/920/ )

and what is the model number of your home router?

Could you please help me check the system info and driver info on the computer, such as https://www.tp-link.com/support/faq/2722/ ;

 

Thank you very much.

Hi, thanks for replying!

 

I tried the driver you mentioned, it acts the same as the one provided with windows.

 

 

I've attached the image above hoping that the issue is made clearer.

The driver 1) is what is installed when I download the software from TP-LINK's website. It works, but I need to try installing it 3 to 10 times before it's finally stable... sometimes the adapter will turn off completely and I have to replug it. When windows is restarted/turn off it goes back to the driver from Microsoft (because it's newer). I guess if you just updated the date on this driver and republish it, most of my issues with the adapter would be gone.

 

One of drivers 2) or 3) is the one provided by my windows installation. The other one was added after I installed the driver you linked here. Both behave the same, like the device is being plugged/unplugged continuously. They'll only connect if I had a 2G network previously selected, and the connection is spotty (stuttering in games, for example). Once I try a 5G network, it'll go turning on/off repeatedly and not connecting at all.

 

I've had the adapter for almost 6 months now, and it showed this issue from the first day. I never contacted support because I found the "workaround" of installing the "TP-Link Wireless MU-MIMO USB Adapter" driver, and I thought I could live with it. It's just that last week the connection was lost several times when the computer was idle and not reconnecting even after 20 or so reinstalls/replugs of the driver/adapter.

 

About the system information:

Driver version of the driver that WORKS on 5G:

 

Driver version of the one provided by windows:

 

Driver version of the one you provided on this thread:

 

I've noticed that the one installed from the website is the same version you provided here, albeit with a different name. Unfortunately, it doesn't work when trying to connect using the one you linked. I've tried several times and the only one that I can connect to a 5G network is the first driver.

 

I've attached the msinfo32 file you required, but I had to zip it because the .txt file was over 10mb.

 

Thanks again in advance.

How did you manage to fix the problem? I think there Is an issue with the Windows 10 provided driver.
