High Pings and lag in games.

Question

The problem I have is with gaming early in a morning and towards lunch time are usually fine and late a night into the early hours are usually ok aswell but as soon as peak times roll in my online play is impossible due to high pings and very bad lag, any idea what could be causing my problem please?
Steps I have taken to date, contact BT and was passed onto tier 2 tech support who then ran a noise check which last 24 hours on my line, which seems to have left my line with a higher noise value than before.
Tried a different ethernet cable, different micro filter, unplugged everything from the socket except for my Homehub 2, turned off my firewall and virus checker, reset my computer, closed all unused programs. Tried a friends Homehub 2, tried a laptop, all have the same result with high pings and lag in games.
Also BT quote my line speed should be an estimated 17MB.
