How to configure dlink wireless router DSL 2750U?

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 -

1. 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.
2. Turn on the router open a browser window and navigate to 192.168.1.1 (default username and password are both "˜admin')
3. 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.
4. 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.
