Mistakenly partially posted an answer above, apologies.

Since linux automatically updates the BIOS version, I believe 1.07.06TMB to be the latest version for my hardware. I would have to verify it with a USB on the weekend.

2.2.c) Changing these settings did not help (similar connection). As I've said above, other electronics including laptops and phones worked well with the previous router settings. So there should be no issue with this and I will revert back to its defaults.

2.2.d) It is "WPA & WPA2 Personal" with password protection. The same as my other laptop that works perfectly fine. They both use Automatic settings with IPv4 and IPv6 Methods (Automatic (DHCP) on IPv4 and Automatic on IPv6 for both computers).

2.2.e) The attached compressed file contains both dmesg.log and shortest trace.dat I could generate.

My questions would be:

1) Is 50.3e391d3e.0 the latest driver version for AX 201? Would the issue be related to that?

2) Latest firmware from this link had the following files:

However "modinfo iwlwifi" does not display above firmware with the ucode extensions. Could that be the reason?

3) If possible, how would I get the Intel driver mentioned above use the Intel firmware I've downloaded from this link: https://www.intel.com/content/www/us/en/support/articles/000005511/network-and-io/wireless.html

Because it seems newly downloaded firmware is not being used.

I do appreciate your and others' help on this.
