BSNL wifi passkey not matching

hello people!
i have been reading this forum since long as its like top rated by bsnl and always helped me a lot!
now i am in such trouble that i cant manage to get rid of it by google!
i just formatted my laptop and reinstalled win 7 ultimate, now wifi connection asks for passkey as usual as i have secured connection. But according to it, its not correct passkey i am giving in, i even checked from 192.168.1.1 the pass key is perfect!
i tried resetting the modem and doing it all once again but no luck yet!
any help would be greatly appreciated!

Try without a a security key . Feedback.
Key used wep wpa etc ?
Mention modem/router model/make/number.
If possible post scree shot as Annexure here, the wifi settings page with the Passkey.
( you are allowed to use Annexure mode )
