�.so I was thinking of upgrading to Sky Q Hub....
I would not upgrade to a Sky Q router at this time as the wifi on the present Sky Q Router is poor.
if you want to use a Sky Branded Router then it may be worth waiting for a few month when, (as I understand it from discussions with Sky), a new Sky Q "HUB 2" Router should be available and since part of the reason for bringing out a new version of the Sky Q Router was the poor wifi the new sky Q "Hub 2" Router may have better wifi.
If you do not want to wait; I personally use the TP-Link AC2800 Router which I find has quite good wifi and it is easy to set up with Sky Fibre.
