the bt speedtester will not load at all.
Have you got Java installed on your computer, it will not load without it?
Its not installed by default on Windows, you have to install it yourself.
Also just to add, i totally lost internet access on friday night(blue light would appear for around 20 seconds then go back to orange), via my homehub. Changed to netgear router and my connection has never droped, just painfully slow.
I have used the router im currently using with this connection before and not experienced problems in the past.
