@786-RAHUL 

Thank you very much for your prompt support. I have one more question to ask. My broadband service provider failed to configure this router. Can't it be connected to fiber net ? If yes, please mention the process.
Big thanks in advance.

@Nightingale 

By fibrenet i am assuming you are taking about broadband connection with optical fibre

Yes you can use it.

On the other hand i am also a customer and i have never had any fibrenet connection in my life.

But before connection inquire the service provider if internet service is available on your particular.

One more thing  

in the 1st pic see if the router is on that configuration

in 2nd pic try to change some settings based on your isp provider.

May be it could work try again.

@Sunshine I have same problem 

@786-RAHUL New firmware version has come so please download it and update your firmware.

next after updating firmware create profile with these settings.
