There are many factors that may cause "no Internet". First you need to check if you are still able to Ping the router LAN IP. If you can get reply from the router, it's not your local network problem.

 

Then check the WAN IP and try to ping a public DNS address like 8.8.8.8

If you can get reply from public DNS server, then all you need to do is just changing the DNS on the router DHCP settings;

If no reply from the 8.8.8.8 you will need to contact the ISP

Thanks for the reply back but whenever my i loose the internet its load balancer is available and i am able to access it. will try to ping the public DNS next time. the concern here is i have two internet connections it will be highly unlikely that both are in-accessible

  @Somnus So after 2 days the problem is at again... i had added DNS setting to my two different WAN connections. 

 

Attached are the CMD screen shot

From the ping test you can still go to 8.8.8.8, that means the connection should be working.

 

Try go to router DHCP settings, and change the DNS for the DHCP server. Then reboot the router to make it take effect.
