Hi

I have a trio of Deco M5 networks in "Router" modem, where the "main" Deco unit is connected by Ethernet to my (Virgin Media Hub) in "Modem mode".

I am experiencing intermittent drop-outs during a given day, but this is MOST noticeable with my Google Nest Thermostat (+ Google Nest Heatlink) devices, where they CONTINUALLY drop connection to the network (up to 10 times a day). I have to manually select "Check again" on the Google Nest Thermostat device for it to reconnect.

Similarly, I cannot control my heating from my phone anymore.

It WAS working perfectly up until 2 weeks ago, where I had a power cut and had to do a factory reset of my "Modem" (router/modem).

Briefly, my settings are as follows:

UPnP is enabled via the Deco app

IPv4 is set to "Dynamic IP" via the Deco app

IPv6 is set to "Disabled" via the Deco app

Fast Roaming is set to "Disabled" via the Deco app

This is REALLY frustrating so I'd be grateful to anyone who can help out :).

Thanks,

Nick
