how does your line speed work is it the amount of people on broadband in your area,i have heard a lot of people moaning they have slow speed and have to disconnect to get a faster pipe,i am only on 512 and my slowest speed yet was 476 but i only live in a small village has that something to do with it?.
I think you'll find that you are probably in the majority. The load balancing issue that has been apparent for the last few months has caused issues for some, but most people probably never noticed any problems, I can say this from personal experience as I'm one of them. Can't say I've ever disconnected and reconnected to get on a "faster pipe".
Others will disagree with me, as there are plenty who have had a problem, but this is one thing you can really only judge for yourself.
