[USER=91333]@zoozoo[/USER] I personally prefer a basic ONT without wifi and other bells/whistles, and use my own router + AP as needed. Coming to the ONT, I've personally used Huawei HG8120C and Digisol DG-GR6011. The Digisol is basically a VSOL rebrand, so you can find the same unit from other brands as well. There is TP-Link ONT as well, but the success rate with their currently available variant/model isn't that great. The HG8120C, you can find on IndiaMart. All these are in the ~ Rs 1000 range.
Once you have the ONT, you just need to clone the GPON serial, you will get this from the back of the Airtel ONT/Router or the management UI. On the target ONT, some will allow you to do this from the UI (example Huawei), others from telnet.
Once the serial is cloned, the the new ONT should come online with a stable PON light.
Please ensure you match the colour of the fiber connectors, Airtel normally uses the green connector (SC/APC) so if the ONT uses blue (SC/UPC), then you would also need to get green to blue cable. If the connectors are not matched, there would be signal loss.
After this you should be able to use the ONT in bridge mode and use your own primary router.
