Well, 9.32am. The Ntl Engineer has been and gone and I now have a nice new shiny Samsung Set Top Box. Internet Resumes and downloads/uploads a little faster than before.
Only time will tell now if problem was with the STB (which I suspect) or not.
I will post back and keep this thread updated.
P.S.
A special thank you to
JustAnotherN00b for all his help last night. Much appreciated Amigo.
Adios for now.
