Today my Deco P7 drops wifi connection. I cant connect via wifi from any device, but when I open Deco app on Cellular data i get connection with deco. There are still some devices connected to deco (9 out of 34) and can access them via cellular data. All other devices drops connection. All I get is weak security warning on my phone, nothing else happened. I tried to create Guest network with no password but no luck on connecting to it.
My settings: only 2,4ghz, ipv6 off, fast roaming off, sipalg on, upnp on, beamforming on
