in my window 7 when i type 192.168.1.1 it ask me user name and password as i was looking for wifi password...i tried my netgear router password but it's not accepting as i'm not able to connect my wifi devices although able to use internet.

I'm sorry, but no one here will know what password you set in your router to access its config pages. If you don't remember it your only option is to perform a hard reset of your router and reenter all the settings from scratch.

Also you can contact the router manufacturer for further help.
