Wifi keeps getting interrupted every few seconds with AX200 (rev 1a) on Linux 5.16.5-200

Problem Statement

My Wifi connection is dropping every 2-5 seconds, making the connection almost unusable.

 

This happens when using Wifi + Bluetooth at the same time as well as when only using Wifi and disabling Bluetooth.

 

The following driver options did not help either:

options iwlwifi power_save=0
options iwlmvm power_scheme=1
options iwlwifi bt_coex_active=0

 

The problems have gotten worse since the last kernel update but where present as long as I have the card installed ~3 months.

For now I have to use other machines to get work done.

Here is the info from my setup, please let me know if there is more I can provide to get this fixed.

Hello b-m-f, 


Please type the following commands and provide the output via the command to the terminal:


  1. $ hostnamectl.
  2. #lspci​  
  3. # modinfo iwlwifi
  4. # lsmod | grep iwlwifi​   
  5. # dmesg | grep iwlwifi​   
  6. # dmesg | grep “no suitable firmware found!”​


Also, please 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 it from the wiki FW dump too.

Hello Josue,

 

I have tried using an M2 card on the motherboard directly and it resolved the issue.

 

 

It seems that this was a hardware issue on either the mainboard USB connection or the PCI based card.

 

Thank you for your assistance

Hello b-m-f, 


Thank you for the information provided.


It is also worth mentioning that when integration is made, it is important to check for compatibility with the motherboard manufacturer as there could be certain cards that will not work with the system or that may not work as expected. Also, for your case, please check with the manufacturer for any hardware issues as that can also be causing problems. 


Hope this information is useful, if you need any additional information, please submit a new question as this thread will no longer be monitored.
