Suddenly gaming has become inconsistent

[#1]

Hi Guys,
I just wanted to come back with an update, since Saturday night it's all been working fine. I'm not sure if any changes were made (or even changes between ISPs), but it's been solid since then and I'm not getting any TCP Retransmission messages on my wireshark captures.
Many thanks for all your support,
Graham

Howdo
Only thing that springs to mind is that the kids have started to go back to school, so from Sat/Sunday onwards people will have been putting them back into a more 'normal' sleep pattern, and parents probably just discovered they had 3489730984 pieces of homework to do 
Hopefully someone prodded something though
