Thank you for explanation, but problem is that is spamming dns server every 5-15 seconds. It's doing this when the main internet connection is up and i have working wifi on my devices. This happens...

@TP-Link_Deco Sorry for the late response, but i didnt have log from that time. Now deco is acting up again. Log atached as file.

Why Deco in access point mode keeps contacting sites like: amazon.com netflix.com youtube.com linkedin.com google.com DNS querys for this sites are spaming my dns server every 5-10 seconds. WTH????
