While trying to find out yourself, have you found and followed these hints here?

You did not give much info or context - not even on the affected wlan adapter.

Holding off on calling it a solution just yet. But, that link was perfect, it led me down another rabbit hole.

It looks like the error is not the kernel but rather the adapter and/or channel selection on the router.

I switched to using DFS channel 140

Edit: add network device information (Intel / Wi-Fi 6 AX201 160MHz)
Device-1: Intel Tiger Lake PCH CNVi WiFi driver: iwlwifi v: kernel
*It appears to affect many Intel adapters
