I'm a subscriber to the xnet fusion plan. I recently have been in the middle of moving houses, so I got the connection set up at the new address while still being active at the old address. One day the internet at the old address stopped working (I rang up and found they had disconnected it), so I promptly moved into the new address.
The modem doesn't connect at the new address. It's a D-Link DSL-G604T. When the connection was cancelled at the old address, the status page was just stuck on "Waiting for a reply", but now it doesn't connect at all. I've tried another, quite old adsl modem and that had the same problem. I've tried different line filters, no filters at all, and every jack I could find in the house(including one that took the ADSL jack natively which I found kind of weird).
My issue at the moment is this: I could ask xnet to book in someone to check it, but if there's no fault it would obviously cost me a ridiculous amount. Are there any other diagnostic tests I can do? Apparently the old people at the house messed around with the wiring a bit, should I start opening up boxes and poking around?
Any help would be hugely appreciated! Living without internet is the sux0rs.
 I should probably mention that neither place has a phone service running, and the new address hasn't had any service attempted since the old people moved out(about 4 years ago)[/edit]
