@IntrovertSins Thanks for the reply. That's brilliant.

Is there anyway of keeping the parent controls on the Deco? I have a 16 year old son and the parent controls were a revelation.

I did see a post where someone was setting up a DMZ (not that I've figured out how to do that either).

Alternatively can I remove the sky router completely?

  @IntrovertSins Thanks for this. I'll give this a try. Do I still disable wifi on the Sky router?

For the devices that have time sensitive applications, e.g. video conferencing, voice gaming, would direct connection via the ethernet port on the Sky route negate the Double Nat issue?

Ethernet connection to the Sky router modem will be te best but in terms of wifi  You will just end up with two  networks close to each other causing interference.

Just try to run everything wifi  from the Decos and see how things go.

  @IntrovertSins Thanks for the reply, but if I've disabled the wifi of the Sky router, using the Deco for wifi and I'm just taking a direct ethernet connection from the Sky Router there would be just 1 Wifi network. Would that work better?

  @UrbanB 

That would make sense and should work fine.  

  @IntrovertSins Sorry one last question

If I'm running this in router mode would I have to create a DMZ on the Sky Router to my Deco M4? Apart from success fully logging into the sky router and going into the advanced TAB I have no clue how to do this. :)

Sorry have not done any DMZ stuff before, maybe you will get a reply later or research. I would try the setup suggested before trying anything else. What speeds are you getting on Sky , standard copper internet  speed 70-80mbps  or is that the proper fiber connection

The deco M4 is quite an older system spec wise and not sure what the Sky router wifi is ( if its supports wifi 6 which the deco m4 does not ) . Have you used the sky router wifi to check which is better.
