AX201 switches from AX to AC mode

Olexander — Thu, 15 Oct 2020 23:24:28 GMT

Hi,

With the default settings of the WiFI adapter, on the latest version of the driver (see log) - the adapter works in AC mode instead of AX mode. And only if you change "Wireless Mode" in the adapter settings to anything other than "4. 802.11ax" and connect to the access point and then back to "4. 802.11ax" - the adapter starts working in AX mode.

Why is this happening is it a bug?

Hello Olexander,

Thank you for posting on the Intel® communities.

To better assist you I would appreciate if you could confirm the following information:

For how long you’ve been experiencing this behavior? Was it work fine at a certain point?
What is your router model?
Do you remember if this issue happened after a new OS update or Wireless driver update?
Is this the original adapter that came pre-installed in your system or have you changed/installed a new adapter recently?
Have you checked if this issue happens on different networks?

Hi @Esteban_D_Intel

1. I don't know, I accidentally noticed that the network adapter is operating in AC mode. I can't determine when the problems began. The only thing is that once I bought and configured the new router (august this year), the network adapter worked in AX mode.
2. Asus RT-AX58U (Firmware Version:3.0.0.4.384_9505)
3. Unfortunately, I do not know. The only thing I did yesterday when I rolled back the old driver version (uninstalled a device with drivers) was that the old driver was also working incorrectly.
4. Pre-installed adapter in ROG Strix G512LI
5. This is a home laptop, one router, сan't check on another Wifi router.

Hello Olexander,

Thank you so much for the information provided.

When talking about laptops, it’s worth mentioning that Intel provides generic versions of software and drivers.

Your computer manufacturer may have altered the features, incorporated customizations, or made other changes.

I would recommend the installation of the drivers provided by the manufacturer to ensure top performance and then check results.

You can find the latest driver for your laptop in the following link.

As you can see, the validated driver version for your laptop is V21.90.3.2

Please try a clean installation of that driver and check the outcome with me.

Hi,

I installed the driver from the manufacturer's website. I did a clean installation with "old" driver uninstallation. This did not solve the problem. At first, the network adapter worked in AX mode, but after rebooting the laptop (updated the video driver), again started working in AC mode

Update:
Looks like it was fixed in the latest driver version. It will take a few days to check if all works fine because yesterday the router firmware was updated as well.
