No sign of an engineer today. Rang CS and they said that if the problem was at the exchange they may not necessarily come to the house.
There does not seem to be any change in the speed of my connection. Connected at 20MB but should be closer to 37 and the upload is 657KB as opposed to nearly 10MB.
Do i have to wait for it to retrain after all the problems?
There is absolutely no substitute for a genuine lack of preparation
