Which "error"?

Most are not an issue, it's just the LEVEL assigned to the message.

Are you experiencing a problem with something?

Not really sure the only thing I notice over Wi-Fi speed is low on both channel 2.4G/5.0G where as on ethernet getting full speed.

On Wi-Fi 2.4 :-
Download speed is varying from 70-110Mbps out of 100Mbps
Upload speed is 100-125 Mbps out of 100Mbps

ISP Wi-Fi
2.4Ghz-0

DIR-2660-A1
2.4Ghz-1

On Wi-Fi 5.0 :-
Download speed is varying from 30-80Mbps out of 100Mbps
Upload speed is 100-125 Mbps out of 100Mbps

ISP Wi-Fi
5.0Ghz-0

DIR-2660-A1
5.0Ghz-1

Ethernet Download/Upload both near 100Mbps+ out of 100Mbps
LAN

Note:- There are almost 15-25+ SSID broadcasting in both 2.4G/5.0 channel.

Every time on boot log filled with this warn/err not sure if it cause some issue.
