GL-A1300 Slate Plus - CTRL-EVENT-SCAN-STARTED and CTRL-EVENT-SCAN-RESULTS every 9 seconds

Hi all

I purchased a GL-A1300 Slate Plus router a few months ago. I’m using it in repeater mode on my home network to give me a separate subnet. Initially it was working fine but after a couple of months I noticed that the blue light on the front started flashing all the time and I had lots of dropped pings in the log. I eventually fixed it by switching off IPv6 on my main router (Asus RT-AC68U) which I had recently switched on. I’m not too bothered as I don’t really need IPv6 at the moment, but I am curious as to why that caused problems. IPv6 is not enabled on the Slate Plus. Anyone have any ideas?

Also - since that issue was fixed I am now seeing the following messages every 9 seconds in the log:

Fri Jun 2 10:35:26 2023 daemon.info repeater: (/usr/sbin/repeater:470) <3>CTRL-EVENT-SCAN-STARTED
Fri Jun 2 10:35:26 2023 daemon.info repeater: (/usr/sbin/repeater:470) <3>CTRL-EVENT-SCAN-RESULTS

Fri Jun 2 10:35:53 2023 daemon.info repeater: (/usr/sbin/repeater:470) <3>CTRL-EVENT-SCAN-RESULTS

I haven’t noticed any performance degradation but I’m wondering if it’s normal to see these messages in the log so often? Is there any way I can get rid of them?

Edit: I’m running firmware version 4.2.1.
Edit: I’m connecting to my main router on the 2.4Ghz band and have only enabled the 5Ghz band for clients connecting to the Slate Plus.

Many thanks for any help

Further update - I changed it around so that the Slate Plus connects to my main router on the 5Ghz band and the clients connect to the State Plus on 2.4Ghz. That seems to have stopped all those messages appearing in the log. Client speeds aren’t as fast as they were the other way around but it’s good enough.

I still don’t understand what the messages mean and whether they impact performance.
