Slow, Slow, slooooooowwww

My BT Business broadband has been so slow this week that you could make a cup of tea between screens (and drink it).

Anyway I’ve just disabled BT Openzone & BT Fusion which I gathered don’t usually affect the speed, and instantly it’s lightening quick.

Also my wireless signal strength is much better when working far away from the router.

Has anyone else found this?
