Hi TP-Link Community.

Searching the web I found this thread which describe exactly my problem. Unfortunately, the thread is closed with no answer. I copied hereunder parts of the text from the original thread. I'm leaving in Belgium (native language: french).

===============

I recently discovered that when the WAN / DSL / Internet connection on my main router drops, the Deco mesh stops working (led orange). Deco M5 in AP, Smart DHCP disabled (DHCP managed by the router).

I didn't think the Deco would be dependent on the WAN side of the router working and I'm struggling to understand the rationale.

================

My problem is that I have many smart devices connected to my wifi and I cannot access them anymore when Internet is lost: boiler, heater, ...

Thanks.
