william, what was your original sync speed when you signed up?
also, can you put either your telephone number, or address in here and let me see what it says the max for your line is, i think the address checker is the best.

for your sync to drop there are a few variables, 1 is that your line could be faulty, 2 there could be interference from either an internal or external source which causes drop outs and 3 crosstalk.
crosstalk means that due to new customers signing up in your area, it drops your max sync as more bandwidth is taken up.
generally if its crosstalk, you will not see a latency increase, if its either of the other two, you certainly will.
can you also please open up cmd and ping bbc.co.uk and share the results, this way i can tell if youre interleaved or not, thanks.
