A lot of these steps are probably recyclable for other routers more so for other D-Link products that use a similar interface.
Basic setup -
- Connect the power adapter to an outlet the RJ45 cable to a computer (Windows Mac or Linux) & a LAN port and the RJ11 cable to the WAN port and your splitter's ADSL out port.
- Turn on the router open a browser window and navigate to 192.168.1.1 (default username and password are both "˜admin')
- Navigate to Advanced Setup > Layer2 Interface. Add a new DSL ATM interface (mine is shown below). Enter the VPI/VCI values given by your ISP. Unless you're sure of what you're doing do not edit the more advanced options. They ought to work in most cases.
- Next navigate to Advanced Setup > WAN Service. Add a new WAN service and point it to the DSL ATM service you've just created. At this point you'll need the username and password provided by your ISP. I copied most of the values I needed for steps 3 and 4 from the preconfigured modem (given by my ISP) that I was using earlier.
