Please help...Wifi connected but without internet

Got bsnl fiber installed yesterday . Everything was working fine till today. But today after a 30 min power cut I am unable to connect to internet. All the led indicator on my net link PON router are green and stable. Wifi is connected but without internet. What to do ? I also plugged out the router from power source and connected after 5 min. But still no internet. Please help

What is the status of LOS light ?
And Check router admin portal for the status of connection

try 192.168.1.1 un & pass : admin admin. Or book a complaint BSNL CUSTOMER CARE .
