Just some quick tips which may have not been fully covered.
Firstly - do not turn it off (this has been covered but I will reiterate that point, these things make adjustments in the middle of the night, they are expected to be always on. I believe the Sky Hub even comes with a sticker saying to keep it always on).
All line adjustments, line management etc will happen overnight. If routers off you'll mess it up. Also it is recommended to keep the Sky TV box connected for upgrades also carried out overnight.
Secondly you need to be using that master phone socket

It has a slit in the middle as highlighted.
You do not want to be using one of these sockets

Also ensure that every single socket has a filter before anything else.

Notice in the image it goes phone socket - filter - phone connected
This has to be applied to every socket
This kind of setup is terrible

No phone socket should have a device connected without a filter
IE Sky box plugged directly into phone socket = terrible
Landline plugged directly into phone socket = terrible
It should be phone socket - filter - sky box
phone socket - filter - landline
Using these kinds of extensions is a big no-no (they will screw your speed up)

So to clarify you need
Master socket - Filter - Sky Hub
Any extensions - filter - device in use (sky box, landline, fax machine all need to be filtered)
No cheap flat telephone extension cabling for the broadband.
Cheap extension RJ11 cables like these are a big no-no

Extend the network with Ethernet if you must (or just a very high quality cable) - Ethernet is preferred.
EDIT: WiFi using the default kit is unlikely to deliver close to the 80Mbps speeds. So you are aware.
