@Solla-topee Hello, 
I am having same issue for 1-2 months now. It is incredibly annoying the fact that despite this device being sold as we speak, the driver for it is not working ok with the latest version on Windows. To be honest, I think the issue started a few months ago after some new windows 10 updates.

I have the same network connection drops as all the mentioned issues by others. I can tell by running ping continuously and checking this. Sometimes it drops and get 1-2 consecutive timeouts consequently and sometimes I get a lot of them, with VPN dropping, "no internet" messages, etc. 

 

T3U Driver version: 1030.41.514.2020 (I tried all of them from this forum, even the beta one)
Windows 10 Pro

Version: 21H1

OS build: 19043.1110
Experience: Windows Feature Experience Pack 120.2212.3530.0

 

I can tell you 99% sure that this is because of your wireless adaptor, more specifically because of stupid Realtek chipsets (in this case, RTL8812BU).

Here are the reasons:

1. I also tried a different adapter from D-Link (DWA-181), which turned out used the same chipset and of course, the problem was the same. 

2. I tested with 2 routers and one mobile hotspot and the issue is the same (so it's not a router issue)

3. I tested these WLAN USB adapters on another laptop and the issue is the same
4. I tested with freshly installed windows and the issue is still there

5. The other laptop on which I tested has a WLAN integrated card from Intel and it works absolutely great! No timeout at all! 

 

Here is a short description of how to try and reproduce the issue:

- run continuous pings to the router (ping -t 192.168.1.10 in my case)

- wireless network has to be private and the pc should be discoverable on the network

- open the "Network" window either from desktop or from "This PC" (where you shoud see other devices in your network). Run ctrl+f5 a few times to refresh the list. 

- also try and close/open the "Network" window and again ctrl+f5 to reload. Do these steps a few times

This will at least trigger some huge time reponse to pings, like over 2000-3000ms, and even timeouts. Don't know exactly what is so intensive about this, but it was the only way I could reproduce this on current windows, on a fresh installed windows and also on another laptop.

 

Besides these steps to reproduce the issue, the connection drops randomly during different activity like: connect monitor, connect power cable, connect bluetooth headsets, even browsing files. Sometimes I get lots of timeouts during 1-2 hours, sometimes I have only a few or even 0 timeouts. 

 

FYI, my laptop WLAN chipset is also Realtek (8821AE) and I also have those timeouts when using the integrated WLAN.

However, I bought the laptop a few years ago, but you are still selling those adapters with those chipsets. 

I don't really know who should be responsible for fixing this (Realtek, Windows guys, etc), but I know that I purchased this adapter from TP-LINK and I need it to work. 

Please test this, find a way to reproduce and address this issue to the appropiate people for urgent fix. It's a general issue that affects a lot of customers using Realtek chipsets for WLAN cards or adapters.

 

Regards,

Nick
