NWA90AX | Massive issues with Intel AX201

Good evening,

I have recently replaced my Fritzbox with a NWA90AX. Since then, I have massive problems with a notebook using an Intel AX201 Wifi 6 card. I never had similar problems with the Fritzbox and I'm currently quite desperate. I have two SSIDs and ca. 10 clients, most of them supporting 5G, but also some devices which uses 2.4 only, so I cannot disable it in order to solve the problem. I don't see the problem on other notebooks, which are on the same desk as the affected notebook, but I also never had the problem before the NWA90AX, so I hope there is something what can be tweaked to make this problem disappear. 

From the event logs, when the problem starts it looks like a flapping between 2.4 and 5Ghz band. Once I try to reconfigure something to make the problem go away (lower the 2.4 power, etc.) it will run stable for a short time, then the problem starts to happen again. The log is full with entries regarding "disconnected by STA", "deauthenticated by key handshake fail", "blocked by key handshake fail", etc.

Log example:

Currently the 2.4G max power is at 12db, the 5G max power is at 30, and the problem is still happening. Once I have disabled the 6Ghz band (experimenting) for the SSID, the connection with the notebook is established with 802.1a. 
To be clear, I have no problem with using the 2.4Ghz band with this notebook (even though I would prefer 5Ghz with worse signal strength then the crowded 2.4Ghz band with a better signal), but it's not stable on any band. Constant disconnects/reconnects are making the notebook unusable. I would disable the 2.4Ghz band on the SSID, but I don't know if this would solve the issue, and I have other clients which require 2.4Ghz. 

I would really appreciate some help on this. 

Thank you and best regards

    Could you help us update the latest firmware 6.29 version?
    About the “key handshake fail” issue, we have adjusted some settings about it in 6.29 version.

    You can upgrade firmware at Organization-wide>Configure>Firmware management,
    Click the NWA90AX, and click the “Upgrade now”

    If you still have the issue after you upgrade the firmware, please PM us your org/site name. And active the Zyxel Support as an administrator at Help Center > Support Request. We will have the privilege to observe your setting and AP log.

    Thanks

    Hi Jay,

    thank you for the quick response. The AP is already at v6.29. I have activated the Zyxel Support as administrator.

    Thanks a lot!

    I have the exact same problem with NWA90AX. I will request support through the Nebula console.

    Hi @pseudin

     

    Because we have checked the Intel Official website, and Intel has fixed a lot of issues with the device disconnection. Please help us upgrade the laptop network adapter driver to the latest version.

    Then, please help us connect the SSID “media” again, and check if it still has the issue.

     

     

    If it still has the problem, please help us collect the WLAN report from the laptop.

    If your laptop is Windows OS. you can collect the WLAN report at Search cmd > netsh wlan show wlanreport. Please send the HTML file to us.

    And we want to capture the packet between the laptop and AP., we want to create a 5 G-only SSID and let your laptop keep connecting to it. Could you help us keep the laptop connected to it?

     

    Thanks

    Jay

    Hello, We have the same clients' connection problems in a new 8x NWA90AX wifi network setup, all with the last firmware V6.29(ACCV.1), it happens in both bands, 2,4GHz and 5GHz... this is maddening...
