Full marks to PN's staff for sorting out a problem with download speed - and especially for doing so in a way that never once brought me face-to-face with my almost total ignorance of how broadband works!
Thanks for the great feedback. Glad to hear that everything is working for you as it should be and that it was resolved to your satisfaction. If there's anything else then feel free to give me a shout and I'll be happy to help. Chris
