This is my first post on the forum so please be patient with me.
I've just had BT Infinity installed aroung 1 week but I am only receiving around 18-20Mb download when the BT checker stated that I could get 40Mb. I know distance from the cabinet will make a difference but I am not for away from it. What sort of things can I check or test before I contact BT. When the engineer connected the equipment I don't recall him using any equipment to check the sync speed from the master socket. Any help or advice is appreciated.
