Just did 2 speed tests using wireless broadband.
One gave 48.5mbps download & 18.4mbps upload & the other (Which?) gave 51.1 & 18.8.
Don"t know if those figures are any good for you but the performance seems fine to me.
I think that my BT superfast fibre optic broadband advertises speeds of up to 76mbps but that is obviously dependant on certain factors.
Yes I watch a few of the entertainment plus package channels.
