Hi! I just built a linux system but the wifi is so unstable it disconnects every couple minutes. Ubuntu is the only OS on my computer. I need to switch wifi on and off to reestablish connection. I tried to refer to this thread on the forum and installed newest firmware (iwlwifi-Qu-*-59) but the issue persists.
I am using the onboard intel AX201on ROG H470i mobo. Kernel is 5.8.0

Hello kiraliu7,
Thank you for posting on the Intel® communities.
In order to better assist you, please provide the following:
1. Run 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...
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.
- To verify, please type: dmesg | grep iwlwifi > If the result is empty, the driver wasn’t initialized and this is a distribution issue. If there is a result populated, proceed with the next step.
- 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 it from the wiki FW dump too.

Hello kiraliu7,
Thank you for patiently waiting, please follow these steps:
1) Your dmesg log indicates the Wi-Fi fails to load the matching firmware 56 for kernel 5.8.
Please try to load the FW 56 successfully and check if the issue still occurs.
Line 957: [ 3.250465] iwlwifi 0000:00:14.3: Direct firmware load for iwlwifi-QuZ-a0-hr-b0-56.ucode failed with error -2
2) Does the slow speed issue occur when connecting to the Wi-Fi router at 2.4 GHz band?
If so, please try to connect to the router at the 5 GHz band and see if the issue improves
3). According to the post https://askubuntu.com/questions/1230525/ubuntu-20-04-network-performance-extremely-slow?newreg=89f454f5c3714071a14949ed391721f9 , please have customer check if this issue can be fixed by:
Option 1:
editing /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf and then change the value wifi.powersave from 3 to 2, save the changes and reboot the system.
Option 2:
Remove the backport-iwlwifi-dkms package, type: $ sudo apt remove backport-iwlwifi-dkms

Hello kiraliu7,
Thank you for patiently waiting.
It seems the iwlwifi-QuZ-a0-hr-b0-56.ucode is no longer available at git tree (https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/), which makes your current firmware 'QuZ-a0-hr-b0-55.ucode' the Max version available for his Kernel 5.8.
In this way, please try the 2) and 3), and let us know if the AX201 works better.
i.e.
2) Does the slow speed issue occur when connecting to the Wi-Fi router at 2.4 GHz band?
If so, please try to connect to the router at the 5 GHz band and see if the issue improves
3). According to the post https://askubuntu.com/questions/1230525/ubuntu-20-04-network-performance-extremely-slow?newreg=89f454f5c3714071a14949ed391721f9 , please have customer check if this issue can be fixed by:
