AX200 on Ubuntu 20.04 not connect to WPA2 secured WIFIs

[mirkop]

Hi,

I'm not able to connect to a WPA protected WIFI from my laptop.

Output of lspci is

03:00.0 Network controller: Intel Corporation Wi-Fi 6 AX200 (rev 1a)

I'm using Ubuntu 20.04 kernel 5.6.0-1042-oem

output of command dmesg | grep iwlwifi is
[ 3.187470] iwlwifi 0000:03:00.0: enabling device (0000 -> 0002)

Currently I'm able to view the availables WIFI and to connect to a WIFI without security.

If I try to connect to a WPA2 secured WIFI, connection doesn't go OK and the OS continues to show me the password panel after a while

I need some help

Thank you

Mirko

Hello mirkop,  

Thank you for posting on the Intel® communities.    

In order to better assist you, please provide the following:  

1. The brand and model number of your system. You can also provide the Intel® System Support Utility for the Linux* Operating System for more details: https://downloadcenter.intel.com/download/26735/Intel-System-Support-Utility-for-the-Linux-Operating... 

2. Is this the original adapter that came pre-installed on your computer or did you change/install the adapter to this one?   

3. Run the following commands and send us the outcome:  

• modinfo iwlwifi > If there is no output, then the module isn’t installed this is the distribution installation issue.  
• lsmod | grep iwlwifi > If the result is empty, the driver hasn't been loaded. Most likely to be a distribution issue.  
• dmesg | grep “no suitable firmware found!” > If the result is not empty, it means you don't have a suitable FW (api mentioned in the dmesg).  
• Please visit here: h ttps://wireless.wiki.kernel.org/en/users/drivers/iwlwifi  for supported FW, or here https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/ for the latest versions.  

4. If the above steps don't work, collect the debug data:  

Type: dmesg | grep ASSERT    

If the output is empty, please follow this wiki: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi/debugging  to extract dmesg and trace-cmd.  

If the output has value, please collect from the wiki FW dump too.
