Hello Friends
I need ur assistance with my router.
When I first bought it I configured it myself and it worked absolutely fine.
I connected it to my PC via LAN and used to access WLAN on my laptop & smart phone.
Recently, I had to reset it due to some unavoidable circumstances.

Now I can not access its configuration page with ip 192.168.0.1 or with tplinklogin.net
Since I misplaced CD, I downloaded easy setup from here

But I got this error




I then tried to use windows 7 network diagnosis and it reported this error




Though my Internet works fine if I plug the cable directly in my CPU LAN port.
However I get this warning




I dont know what to do. Please help.

Thank You
