Please check the following and let me know:
1. Hope you have connected the ethernet cable to the correct slot in the
router. Let me know how you have connected the entire setup.

Yes. It was my mistake.
Finally I reset the router settings using reset button (on the back side of the router.).
Didn't do anything in the router basic settings - "http://routerlogin.net".
Just opened the "wireless settings" from the Left side menu, and filled the "Wireless Network" options.
Thats it. After clicking "Apply" button, opened the tikona login page - 1.254.254.254, entered the userid/password. Got the connection.
Then I removed all the existing wireless connections from "Network and Sharing Center -> Manage Wireless Networks", clicked on the network icon in the
windows taskbar and selected my wireless network - provided password - opened tikona login page. Got the connection
@maverick29 thanks a lot for spending time for me.
