I'll continue this message to have this logged.

Same errors as mentioned in https://community.tp-link.com/en/business/forum/topic/236538?page=2

Sun Nov 13 08:24:18 2022 daemon.err nrd[11503]: estimatorDot11kIterateCB: Timeout waiting

And status shows that the Deco isn't connected to the internet. Rebooted already multiple times as well as the main router (FritzBox 7590) with no success yet.

This morning it started with all deco's having a red light. Finally it's green but noticing these errors. I can connect to the internet because of the other wifinetwork and lancable connected to the Fritzbox.

When typing this I did another check and noticed that the DNS-server which is being used by the Deco's wasn't available (seemed that my pihole-docker-container wasn't started anymore). Need to enter a secondary DNS, but unfortunately it won't let me do it, so when connected to the Fritzbox it gives the DNS configured to use the pihole, but can't add a secondary dns there.

Note: the errormessages don't disappear though:
