hehe dude it gave me the same problem, what you do is:
1> switch on your AP(plug it in to power) nothing else
2> then on another computer scan for wireless networks, you should see a network called D-LINK or Dlink something of the sort, connect to it
3>the default ip for the system is 192.168.0.1, after connecting, go to your browser and type in the default ip and click go
4> it should give you a loging page
5> the default setting are user name:admin
and your in, you can now play around with it and stuff, be imaginative...
