Thanks. The Engineer told me that I am the first ever customer at the fibre cabinet (1 user so far) blimey. He told me that it will settle down in the next few days and advised me to leave it ON at all times.
Glad u got nice speed wolvesmad. I got BT HH5 but I haven't use it yet cos I am too scare that DLM might kick in and lower the speed if I swap it over. Best leave it alone.
