My mate, richard24, says that he has somehow managed to get his internet connection working again but has little idea which of the many settings he played with that made the difference.
I recommended that he try the IT wizards that frequent this forum to get his answer. So a very big thanks from me that you leant your support and helped him.
He'll probably post his experience to try and point the others in search of an answer in the right direction.
Cheers
