Vodafone is congested between the hours of 7:30pm and 10pm and dropping packets with the result of very slow speeds.
Complained at this time and Vodafone says everything is normal. Forcing me to do Google speed test which shows at best 71Mb/s at around 9:pm but single thread test on TB shows 1.7Mb/s.

it could be local congestion(local pon), which would then require remedial work or its network wide. Ether case, log it for a week or two and then log a fault. You should not be seeing a near 10% packet loss at any time, even at peak 7-10pm. if you have a neighbour on fttp and you two are friends it may be worth doing a contrast and compare.
