So just to give you a bit of a update. I'm in a standard 3 bedroom house, on virgin 3.0hub at 350mbs. I have 14 connected devices and I believe 9-11 of them are WiFi devices, so it's not overhauled at all. 

To me so far out of all the other mesh systems, this is by far the one that has worked the best for me. It does what is meant to, deliveries speed, strength and no dips in service!

Although I have noticed the 'offline' devices will normally hold two of my Ring products there, that being the Ring Doorbell 3 Plus and a stick up battery camera. Now on the Ring dashboard the other two devices will update straight away, as there power is always on, one is hardwired in and the other one is PoE. Sometimes the battery ones will update but this is like 2/10 times, is there anyway I can change this with the app/mesh system? Would it be best if I connected these to the chime pro as that does appear to always be connected. 
 

Also to note I have made the two devices priority devices on the Deco app

Also I turned on IPv6 is this a requirement to be on in general? Not overly sure what it is to be honest. 
 

Any help would be much appreciated!
