forget the CD - - doesn't do squat for this issue.
1) access the router using your browsera) use only a wired connection'
the default address for Dlink is:
[B]http://192.168.0.1[/B]
the default user/pwd is:
admin/ <leave it blank>
2)once inside, set a new Admin Password and save it. This will restart the router and disconnect you from it - - just log back in
3) now go set the WiFi SSID and encryption as required
