Upgrading Sky Router

[GFletch]

I currently have a Sky Broadband Hub.
I'm looking to improve the coverage of my router by upgrading to a third party router, as we live in a large house. 
The price of the router would not be an issue, we just want to purchase the best one for us, to increase speed and coverage, more than 4 ethernet ports would be nice as well but not necessary.
What would you recommend upgrading to and how?

Here are the current Sky router stats if needed:

Just to add, around 20 devices use the internet and up to 4, normally 2/3 use for gaming at a time, mostly via ethernet.

Unfortunately I'd observe that the best router in existence isn't going to help that much with less than 40Mbs arriving at the address.  However, having something which can do bandwidth priority might at least get more to the gaming devices at the expense of the other hardware.
