I think it actually is as jobeard pointed out.
Its quite common for ISP's to lock down the access on the computers MAC adress.
Specially if you only want your costumers to be able to use one computer and pay more to connect more computers.
Its easy to test, there are ways to change the MAC on you machine with programs like http://www.codeproject.com/KB/applications/MacIdChanger.aspx
If you change you MAC, connect to the net, and it works
you just have to buy a router, set it up with a cloned MAC
(the mac adress that workes) and your fine.
Dont forget to reset the mac of you computer back to the original.
