Just tested mine and it's as good as it was this morning, giving me my full speed (on my wireless I get 20 down and 8.8 up, which I know will translate to 37 down on wired - always does!)
Kids are home, so there's many more on the net.
Have you tried stopping and starting the homehub (not the modem), to see if that's any better? Worth a try, if nothing else?
But, I suppose it's possible there's a duff joint somewhere which is responding to the change of temperature. But, finding that is going to be nigh on impossible.
Best log the speed changes over the day (and temps), and remember that BT will only accept WIRED tests to their speedtester as valid speed indication info.
