RT-AX82U asuswrt-merlin.ng channel scan errors

[danielcolquitt]

I have recently flashed my RT-AX82U with the asuswrt-merlin.ng firmware. Everything seems to be working very well with no connectivity issues. However, upon checking the logs, I have notice that the below errors appear intermittently. The errors will repeat a couple of times within 15 minutes and then stop for several hours. The errors do not seem to coincide with any connectivity problems as far as I can tell.

From a brief Google, I suspect that these entries are associated with some kind of channel scan when the router is trying to determine the best channels to use (my wifi channels on 2.4GHz and 5GHz are both set to auto). However, I have not been able to find any concrete information about these errors.

My question is: do I need to be concerned about these log entries, or are they normal?

Edit: After further searching, this thread seems to be relevant, but the only proposed solution seems to be disabling 160MHz — is that correct? Or can the error be ignored?
