There is some problem with your internet setting.
First decide whether you want to use tP-link as access point ( connected to jio via cable) or as a second router ( dual NAT in this case) or as a WiFi repeater.
Then accordingly set the options for internet page of your tP-link router. These options should be in basic/quick set-up section not in advanced.
