Airtel Xtreme Broadband (wont log in 192.168.1.1)

Hi,
I have been using the Airtel Xtreme Broadband for few months. I have been trying to login to the router (192.168.1.1 - User: admin; Pass: admin) on my Windows PC(Chrome, Edge, & Firefox) - Somehow the router interface won't show up on any of the browsers and just displays the screen as below.

It just shows "GPON Home Gateway" on one side & "Logout" on the other side - And displays nothing. I am pretty sure, it has got something to do with the browser(s) - but strangely it won't work on any PC browser - Any quick soln?
P.S - The same (192.168.1.1 - User: admin; Pass: admin) works like charm on my Android Mobile Chrome Browser though 😛 - Check below.

Pretty strange not to see any interface on my PC browsers (Edge, Chrome & Firefox).

Kindly Help 🙂

Have you tried resetting it?

used to face this issue in bsnl adsl. turned off ad blockers / ad blocking and it was back to normal.

Hi! I'm having this same issue, whenever I put password admin it shows bad password and won't let me login
