Tenda Adsl2 Router W150D connection Problem

I bought a new Tenda Adsl2 Router
when I connect it to My pc or laptop it shows error
"Limited or no Connectivity"
I repair it by windows but still same problem.
I can't access 192.168.1.1
please help me to connect
 
Is that a wired connection? Try this before attempting WiFi . . .
