No one could figure out why this was, and so we all blamed Bigpond.
A few days later, I was messing with the connection settings, and guess what, I only needed to tick one box and the internet worked!
This one in fact:
I wont name any names, but I didn't uncheck the box.
It was User Error, but I wasn't the user.
That is all.
Skywalker out!
