Used to be with BT, who managed to get 1.7 meg to me along their ancient copper wire, at phenomenal cost to me. Damned thing used to drop out a couple of times a day, and if I wanted to watch iPlayer clips or anything else even slightly demanding, it would throw a sulk and I'd have to restart the modem.
Moved to O2 several months ago and I now get 4 - 5 meg - a little less speedy at weekends when the locals start their big pron-viewing marathons, or whatever it is they get up to - and it costs me around seven quid a month.
BT is a marketing company of dubious merit that just happens to have a small interest in telephony and something they call the Internets. The sooner these jokers are put out of business, the sooner we can join the rest of the world in having half-decent web access.
The IT? icon cos there isn't one that says 'BT?'
