Sky Stream and BT extender disks

[Alfsdad]

I've recently moved to Sky Stream from Sky Q  and I'm veryhappy with it on the whole

However - it seems that, since I installed it, my BT whole home disks have started to lose connection - for instance, when I turn off the main stream puck, the extender lights go red. 

Nothing in the set-ip has changed apart from the switch from Q to Stream

Is this likely to be a coincidence, router bandwidth problem, or has anyone else noticed similar?

BTW, I'm on 900mbps broadband. 

Thanks in advance....

The Pucks are independent of each other but try changing your power settings so that the WiFi network stays enabled while the puck is in standby just in case it's causing part of the mesh network to fail.
