goes from pc to connection Marked GIG E 4 marked on the hub if that Makes sense?
The Bt chap also wired up a 2nd box, Dont know why tho?
so ive got The infinity box, Which looks Massive on Tv, (its only small thing with 3 lights on PWR /Broadband/wireless)
And this white Thing with Open Reach wrote on it, looks like its been bought from the Quid shop, Thats connected Via lan 1 so as guess that Goes to the Main connection box, phone line /adsl box,.
was thinking of taking the White box off see if the strength picks up,
The white Box is also running hot

I've never seen the home product (it's not available on my exchange, and nobody I know has it).
We just had a business product installed for a new office we're taking over in Cornwall; they called it BT Infinity for Business (or alternatively, BT Total Business Broadband Fibre). Apparently it's exactly the same damned thing as the home product, but with certain perks for business users.
What they installed was a small, unmarked, white box - this is the "terminating box". This is where the fibre comes in to from outside the building. This connects into a larger white box with Openreach on it - this is the "optical terminator", and it acts as a media converter between fibre-optic cabling and RJ45 Ethernet. Then you connect your router - either the supplied BT Hub product, or your own router (i.e. Cisco, NetGear, etc) into the RJ45 Ethernet port on the optical terminator box using a normal network patch lead. We were told that the terminating box and the optical terminator are absolutely essential, leave them alone, but that we were free to use whatever equipment we wanted connected to the optical terminator. So we used a Cisco 891 VPN security router (these are great, but a good bit more expensive than your average home broadband router product).
I don't know exactly what they install for home users.
I am told that it can take a while for the Infinity line to "train up", meaning it could take a few days for you to get the full speed your connection can offer.
Infinity is also sold in three different options:
Option 1 provides up to 38 Mbit/sec downstream and up to 9.5 Mbit/sec upstream.
Option 2 provides up to 76 Mbit/sec downstream and up to 19 Mbit/sec upstream.
Option 3 (not widely available yet) gives you up to 100 Mbit/sec downstream and up to 15 Mbit/sec upstream.
The business packages give higher speeds - their premium package promises more than 300 Mbit/sec downstream, which is just silly.
If you're on Infinity Option 1 then that Speedtest.net result isn't bad - check it every few days or so and see if it improves. And hell, I would never call that slow - I get just a bit less than 9 Mbit/sec downstream on my ADSL broadband, and about 768 Kbit/sec upstream. That's positively glacial in comparison.
If you think that your line is slow, you could have other issues - packet loss, for example; if you're getting packet loss, then TCP/IP will need to retransmit the dropped packets, causing a perceptible slow-down in the connection. That's just one example though. If it's really terribly slow, I'd call the BT Infinity service desk and see if they can work out what's wrong.
