Many Thanks to everyone for their help, advice and explanations....
I see that the daughter is not alone in having Broadband problems caused not by the provider, but by the infrastructure....
And special thanks to Mixture for the pm....The daughter will contact BT directly using the address provided....
Meanwhile, still varying between 125kbps and 250 kbps this weekend.....It really pees us off that this is from the same company who advertise speeds up to 20mbps...I wonder who and how many people really do get 20mbps ?
