Cant remember my network key for my Belkin

First connect your router to computer with ethernet cabled.
Then you can access it with default ip
http://192.168.15.1
then type user as "admin" and password as "admin" or blank "password"
Then go to wireless secirity.
thjnen add new WEP code key it is your new password to connect.
But if you are not able to access router configuration page then you have to reset it.
for that press RESET button it in backl panel of router press it for 10 seconds.
Let me know if you need further assistamce.
Thanks.
