Model: TL-WN821N  
Hardware Version: V6
Firmware Version:

Hello,

 

my WN821N Adapter for the most part works fine (especially if i reinstall the driver, I have no problems until the next reboot). But sometimes, it freezes Windows completely, and sometimes it drops randomly the connection and the Windows Taskbar Item for Network stops working (if i click on it, it doesn't open).

 

I tried:

  • reinstalling the newest driver
  • installing an older driver
  • rebooting (obviously)
  • 3 different USB Ports

 

I found 2 notable Errors/Warnings in Event Viewer:

@dohrli Good day, 

 

Thank you for your detailed post!

 

Here is a chipset driver for TL-WN821N V5/ V6, please give it a try and see it help with the issue: 

https://static.tp-link.com/2019/201911/20191129/Driver_RTL_8192EU_TL-WN821N_V5.zip

 

It is also recommended to Windows version to a newer version as the Error is related to WLAN extension module. 

If the issue persists, can you help confirm the motherboard information of your computer and the driver date as below:

Do you mean wireless stops working every time you reboot the computer,at that time is there any Error, and how the connection recover? 

When did you buy this adapter and when did the problem start? Thanks in advanced for helping with troubleshooting.

Hello, thanks for answering.

 

I managed to resolve the issue at least temporarily by unchecking "automatically connect to network" in Windows.

 

I am installing the provided chipset driver right now and will update in a few minutes if it did change anything.

The Driver date in the Windows Settings look off. I'm a 100% sure I have the newest drivers from the TP-Link website installed.

 

 

This is my hardware:

No, the chipset driver did not resolve my issue.

 

Also, I'm already on the newest Windows Version.

 

The problem arises nearly every time I start the computer, yes. (when connect automatically is checked). There is no error message, I just don't have an internet connection and the Windows Wifi Applet doesn't open when I click on it.

I bought the Adapter about 2 years ago and used it without any problems on Linux (Debian Stable) until about 2 months ago. The bugs started when I switched to Windows.
