Hi,

I've set up my own Pi-hole DNS server in raspberry pi & connect it to a slave Deco unit with a wired connection. I've added the IP of the raspberry pi in Deco DHCP settings so that all the DNS query forwarded to the raspberry pi. Everything working fine but every time when I open the Deco app I saw my raspberry pi disconnect and reconnect every 2/3 minutes. So I've enabled the IFTTT applets which log every time an individual device disconnects from my network where I can see my raspberry pi reconnecting every 2-3 minutes. But I've never faced any DNS failed issue, even when I ping my raspberry pi from my laptop it never dropped any packet at all. Ping is also very stable. For recheck, I've connected my raspberry pi to the main Deco unit & the problem is fixed !! I've to connect my PC to the main Deco unit so there is no port left where I can connect my raspberry pi. I've to connect it to the slave unit. I've already reset the slave unit once but the problem still exists. So why this is happening & how to fix it ?
