I have had lods of speed probs with bt
i live 100meters from the exchange but was getting a speed of 0.23
yes - 0.23
after testing it and complaining it has gone up to 2.35
a great improvement but not good really
i have new lap tops and computer and a good wi fi box
here is a number they gave me - direct to save jumping through options and buttons
0800 012 1335
