If you just want extend the range of your wifi network with a secondary router, forget about bridge mode.

Now, your secondary router may have an inbuilt Access Point mode. If this is the case, connect ethernet cable from LAN1(depends on which port airtel is giving gigabit connectivity; usually LAN1&2 should have it; could be none of them do) port on your Airtel router to WAN port of your secondary router(be sure to put in access point mode).

If you don't have access point mode in your secondary router, connect ethernet cable from LAN1 on Airtel router to LAN1 of secondary router. Then turn off DHCP server of your secondary router.

You can also give your secondary router's mac address a reserved dhcp entry on your Airtel router. This should help you in logging into your secondary router. Login into your Airtel router and go to dhcp settings. There you can reserve an address like 192.168.1.3 for your secondary router using its mac address.
