Hi. 

I am using the AX210 wifi module.
When operating the AX210 in AP mode(802.11n), the following problems occur.
-. The modem resets when more than 7 station devices are connected.

The environment I'm currently working on is as follows.

-. kernel : 5.14

-. OS : debian

-. AX210 Firmware Version : firmware version 59.601f3a66.0 ty-a0-gf-a0-59.ucode

-. AP Program : hostapd

     - hostapd.conf

Hello sykang-with,

Thank you for posting on the Intel️® communities.  

You should know that the Hotspot setting totally depends on the Operating System and not the wireless adapter. My recommendation is to contact your Operating System fur further support.

I have an AC9260 and an AX210.

In the same system and the same option, there is no problem with AC9260,
It only happens on AX210.

I suspect there is a problem with the module or firmware.

Hello sykang-with,

I appreciate your response.

I would assume that when you mentioned having two wireless adapters (AC9260 and an AX210), I would duce that you did a wireless integration on one of them. You should know that the Intel software and drivers only support a single Intel wireless adapter installed on one computer. If you install more than one, you will face system crashes.e

If the AX210 is not the original adapter, you should know that System Manufactures (OEM) do some customizations to meet country regulatory requirements. Since you may have already performed the integration, it is also important to understand that it may not work due to hardware or software compatibility issues or dependencies. You must contact the system manufacturer to determine if the Intel® Wireless Adapters you plan to install are compatible with your system. They may also provide proper integration steps.

Also, as I mentioned in my previous post, the hotspot setting is not dependent on the wireless adapter; it relies on the operating system. I recommend contacting your Operating System fur further support.

So, what does the message below mean?

-. system log

     kernel: [58758.657548] iwlwifi 0000:01:00.0: Microcode SW error detected. Restarting 0x0.

Why does restarting occur for microcode SW as above?
