My particular case was weird, it was fine for over 8 months - constantly 18-20mb every night, then one weekend it suddenly droped to 5mb & pings of about 200.

Then I rang lots of times over the following month as the speed never went above 5mb after 6pm (was always just under 5mb). I was told they'd only added 3 more people and the UBR only had 80 people on it so was not over subscribed.
The following 3 months it drops to 0.2 to 2mb every night after 6pm & im told its an over subscription issue. - hence why they refunded my £30+ last month.

All my neighbours suffer exactly the same.

The weird thing to me was when it intially started droping to 5mb every single night after 6pm, id of thought the speed would of gradually droped over a matter of weeks as more people got added... but no it droped straight from 20mb to 5mb on a friday night & carried on doing that every night that month.. then the following month its the dredded 0.2 - 2mb after 6pm (for the past 3 months).

Reseg hopefully next wedneday/thursday so fingers crossed if it is an oversubscription issue - it gets fixed finally.
