If it's not too late, what i changed it using static setting ( as it was giving 2 options - 1. DHCP without
DNS updation form 2. Static IP option with static IP as well as DNS form). You can get existing IPv6,gateway from status page and enter same in static option. In DNS setting i used
google's DNS.
My reason for changing DNS - While network scan in
router i was getting warnings that some domains have been hijacked and DNS might be vulnerable. Default setting was to use Jio's DNS server.
