Well, I've spent most of the day on the phone with IT (work, not the local provider) having them tell me over and over it wasn't them.
It was them. :dozey:
Now, I've got a decent connection, but geez, can't work while I have it. Oh well. :D
I did have a look at my bill for ISP though and they were charging me for installing a wireless when they didn't do it. That came off pronto!
