You are not going to believe this but your scenario is the exact copy of mine ! I am also on Onetel with 2Mb,same modem and firewall and my exchange is just 500 yards away and my speeds since upgrading two weeks ago are abysmal. I spent all last week emailing their tech help dept and completing speedtests, tracers and even more speedtests on sites nominated by them. All a waste of time. The tests all show that my speeds are between 30/50% down on what they should be but they couldn't care less. They say that have tested my line through BT and there isn't a fault and the speeds I am getting ( anywhere between 960--1250 Kbps. I should be getting 1850Kbps) are average for 2Mb. I am fed up with talking to a call centre in India and getting no help what so ever. I have spent hours on the phone and sent in excess of 12 emails to them asking for a better service and have got nowhere so today I have resulted to faxing them, as no one at the call centre had the authority, asking for someone to have the courtesy to ring me as I wish to cancel my connection. Needless to say. No call. I have been a customer of Onetel for over three years and I am fuming at there take it or leave it attitude.
