Wireless AX211 issue

Latenzkönig · ‎06-21-2023

Hi,

i have on several different Systems a very strange issue.

They absolutely random loose connection and reconnection is also absolutely random.

They might reconnect in some minutes or it takes up to days.

After some further searching and several Driver Updates(Version is 22.230.0 now), it

did not improve.

What i noticed after further search:

All Systems geht their adress via DHCP,

but it seems they do not use the provided IP, you only see the custom DNS entries, but no IPv4-Adress.(Packages arrive, but Client seems to fully ignore the IP-Proposal, doesn't even send a NACK, checked that via Wireshark)

I tested it with several AP's (Ruckus, Asus, Siemens and some AVM Fritz Devices) all showed

the same behavior.

How can that be?

I rember having a similar Issue with the older AX201..... in that earlier case the system did not accept anything from dhcp for a random amount of time, and then all of a sudden it did.

That was indeed some time ago ,but a solution or explanation has not been found.

would be nice to get some Ideas how to get rid of that issue, because i don't think it is wanted that you buy a tp-link-dongle(which is far more cheap AND still runs 24/7) if you have a wlan-device onbard.

(Yes i am a bit angry about this, because of the time i wasted searching already)

thank you

Hello, @Latenzkönig

Thank you for posting on the Intel® communities. I will gladly assist you here.

Please, answer these questions to have a better perspective of this issue:

Is it a desktop or a laptop?
Is the Intel® Wi-Fi 6E AX211 the pre-installed Wi-Fi card in your motherboard or is it an integration (upgrade/ not the original card)?
Was it working before?
How many devices are affected?
Does this issue happen in another network?
Did you make sure your router's firmware is up to date?
What is the model of your router?
Have you tried a Clean Installation of Wireless Drivers, using the latest wireless driver?

Note: Make sure to check you have all the Windows updates before doing the driver installation. Also, make sure to do this step disconnected from the internet (wi-fi or wired connection) when you are uninstalling the driver software since Microsoft updates drivers automatically and prevents doing the clean installation successfully.

Hello Jocelyn,

these are Desktop Systems, the chip is onboard of the MSI PRO Z790-P WIFI DDR4, WiFi mainboards.

If it was working before? Well sometimes it works, but absolutely random, there is no reliable reference that you can count on to predict when it is well and when it will stay disconnected.

It was also impossible to provoke the fault to occur. We got 5 Desktops that have that Mainboard, all of those show that behavior.

That issue happened on EVERY Network i connected those Desktops to.

This is a bigger environment, that means these Desktops are mainly connected to Ruckus R650 AccessPoints, the distance to their next AP is below 5 meters. I also tried using Fritz Box 6660 and some other i found. (Firmware was always latest)

As i Updated to Version 22.230.0 i made a clean install.

This is not the first time i had to go against that kind of Problem, so there's some experience i've made so far.

(That means you can bet, every piece of Software, Firmware or so is absolutely Up to Date)

We had that issue also with Thinkpad Notebooks that had the AX201 chip, the only difference was that those did not take anything DHCP had proposed, and in that Case it were around 400 thinkpads that showed that fault.

Because we did not find any solution or help with that, we told these offices to use wired connection as primary when they are in the office, that made it much better, but did not solve the problem.

We discovered it as we used Wireshark to find out if DCHP Pakets arrive.

That experience was the reason why we found out that the AX211 does nearly the same, expcept taking proposed DNS-Entries.

The type of abort seems to be the same, after Proposal is received, nothing happens, no ACK or NACK that clients do not answer or even ask for repeating.
