Sky broadband issues

[SinSin]

Anyone from the UK got Sky broadband with a Sagem router ? if so have you had problems with low connection speeds
Im supposed to have " up to 20 mb connection" but im only gettin 5mb and thats an improvement from the 0.8 I was gettin yesterday

They say they are sending an engineer round but I could be charged £150 if the problem is found to be anything other than thier products

Squeaky bum time!!
