No stable connection with Intel WiFi 6 AX200 160MHz under Windows

Given: Fritzbox 6590 with latest lab version 7.51, 2 AVM repeaters, older desktop PC (HP Compaq Elite 8300 CMT) with current Windows 11 version (pro), WLAN card Intel Wi-Fi 6 AX200 160MHz. The problem persists even with the latest official FritzOS version.
Ran unobtrusively for years, but recently I have repeatedly for several hours the problem that the WLAN connection is snore slow. Often 6 MBit/s are displayed and then you can do almost nothing in the network. ping -t also shows a strange behavior: There is always an almost monotonous increase of the times until almost 100 ms, then a new cycle starts with 1 or 2 ms and the times run up again. Sometimes also up to the timeout. It doesn't matter if the connection is to the Fritzbox or to one of the repeaters. Mostly only time cures the problem eventually, neither reconnecting nor rebooting the Fritzbox nor rebooting Windows fixes the problem.
But when I then boot Linux, I immediately have a connection with 1-1.3 GBit/s and there always with the box, never with a repeater. Afterwards Windows: Slow again. So the hardware can WLAN very well, only the combination of driver and Win 11 fails from time to time.

Now I'm trying an older driver version: 21.0.0.5 from 2019-02-27. Looks fine. No problems until now.

Now I've tried all drivers on my computer (device manager -> change driver -> search on my machine -> choose from a list, translated from German). Only one driver works good as I mentioned in my last post. On my machine (and I think, not only on my machine!) these drivers are bad:

21.110.1.1 from 2020-07-01: Shows very fast connection, put ping an copies in my local net are very slow

22.0.1.5 from 2021-01-17: Same as above

22.150.0.3 from 2022-05-24: All values are very bad (connection speed: 6 MBit/s, ping, and copy speed in my local net)

22.200.0.6 from 2023-01-17: Same as above

22.200.2.1 from 2023-03-09: Same as above with a little bit better connection speed (about 165 MBit/s)

What's going on here with the drivers? I fond only one "golden" driver, 21.0.0.5. Is Intel no longer capable of programming good drivers?

Hello BuSchu,


Thank you for posting on the Intel® communities.


I am sorry you are having issues with your Intel® Wi-Fi 6 AX200, I will be glad to assist.


Was the AX200 adapter preinstalled, or was it added to your system?


Please try a clean installation of the latest wireless driver v22.200.2 (https://www.intel.com/content/www/us/en/download/19351/windows-10-and-windows-11-wi-fi-drivers-for-intel-wireless-adapters.html). Make sure to follow the clean installation instructions (https://www.intel.com/content/www/us/en/support/articles/000022173/wireless.html).


If the issue persists, please download the Intel® SSU https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows- 


Open the application and select "Everything", click on "Scan" to see the system and device information. By default, Intel® SSU will take you to the "Summary View". Click on the menu where it says "Summary" to change to "Detailed View". To save your scan, click on "Next", then "Save". Please attach the file to your reply.



Best regards,


Steven G.

The AX200 adapter wasn't preinstalled. It's an old HP system, HP Compaq Elite 8300 CMT, see the attached file.

 

After uninstalling the card in the device manager and rebooting, the current driver v22.200.2.1 was automatically installed. With the same bad result that I already knew well. I then went back to the driver 21.0.0.5 which was good for my system.

 

Thanks for your help!

 

Best regards

Burkhard Schultheis

Many thanks for your reply.


Before you install/change an Intel® Wireless Adapter in a system, you must contact the system manufacturer to determine if the adapter you plan to install is approved for use in your system and country. It is also important to understand that it may not work due to hardware or software compatibility issues or dependencies.


Feel free to read more information about Regulatory Information Regarding Wireless Hardware Installation or Upgrade (https://www.intel.com/content/www/us/en/support/articles/000005687/wireless.html).


I am going to keep working on this. As soon as I have an update, I will let you know.


Best regards,

Hello BuSchu,


Many thanks for your patience on this matter.


Based on the steps performed and the fact that the adapter was integrated to your system, our best recommendation is to contact your computer's manufacturer (HP) to check compatibility and for further support.


Please keep in mind that this thread will no longer be monitored by Intel.


Thank you for your understanding.  


Best regards,

Now I've tried the latest driver (22.220.0.4). It is much better than the previous one, but the performance of the older driver 21.0.0.5 is better (ping times are shorter). It is a step in the right direction, but not perfect.
