AX 201 not connecting after update

[Vieken]

Hello,

We have several new laptops (Dell Latitudes) with an INTEL WI-FI 6 AX201 wireless network card.

After the driver updated to version 22.10.0.7 we lost the connection to our wireless network. I can see the ssid but I can't get any connection.

I only get a connection when I change driver properties. When I change '802.11/n/ac/ax Wireless mode' to disable I have the connection again. The other options are not working, altough I have connection with my own laptop (Lenovo) with 802.11ac.

I also tried the 22.20 driver but I have the same problem. Any ideas?

Dear Sebastian,

Thank you for your answer. I'll try to provide you everything. Right now I'm working from home and we only have the problem with our AP's at work. I'm not sure if the first test has to be at work or not. I can redo it again later.

1. See txt in atachment

2. Yes, but in the older driver it was not a problem. See screenshot.

3. We have about 20 devices like this. Some are still working because they driver hasn't updated yet.

4. It worked with version 21.110.2.1 of the driver

5. Our AP's : Aruba Instant 105 - Aruba Instant 135

I have exactly the same issue, the older driver worked with the Aruba Instant 135, but the new driver fails to negotiate the link, but does see the access point.

Hi,

I had to contact Aruba Support because I couldn't find the latest firmware. 

They did everything for me with a remote access because in our case it wasn't that easy.

Now everything works great again.

[drb0]

Do you know what firmware version they installed?

[Vieken]

We have version 6.4.4.8-4.2.4.17_75903 now.

Hello Vieken,  

Thank you for your reply. 

Please check the following: 

1. Can you confirm if the driver version22.10.0.7 you are using was downloaded from the Intel or the system manufacturer (OEM) website? Otherwise, do both versions work regardless of where you download them from?  

2. I will recommend you to try a clean install of the wireless drivers provided by the OEM: 

• Clean install steps: https://www.intel.com/content/www/us/en/support/articles/000022173/network-and-io/wireless.html  
• Download link: https://www.dell.com/support/home/en-us/product-support/product/latitude-13-5310-laptop/drivers  

3. Also, you may check with the AP manufacturer to see if your AP has the latest firmware installed and for additional configuration settings, as this problem only happens in your work environment.

Hello Sebastian,

I just updated our AP's yesterday. It wasn't that easy because they're getting old and we realised we have to invest in new ones.

Anyhow, the update resolved our problems with the AX201 cards. We could connect them without any problems. So, thanks a lot for you help!!! We really appreciate it.
