About this tool
Scored checklist to lock down an Airtel Xstream Fibre ONT — admin login, Wi-Fi encryption, WPS, UPnP, remote management and guest SSID.
A scored, sixteen-step hardening pass for the Nokia, ZTE, Syrotech or Tenda ONT that Airtel supplies with an Xstream Fibre connection. It covers the admin login at 192.168.1.1, the factory Wi-Fi key on the label, WPA2-AES versus WPA3, WPS, UPnP, WAN-side management, TR-069 provisioning on TCP 7547, stale port forwards and the guest SSID — each weighted by severity, so the score stays capped while any critical item is unfinished. Every item names the exact menu to open and a way to confirm the change took effect.

Admin password, Wi-Fi key, WPA2, WPS and WAN management carry the most points, so the dangerous gaps surface first.
Each step names the actual ONT menu and explains what Airtel controls through TR-069 that you cannot switch off.
Every item includes a check — reconnect a device, scan the public IP, confirm the old key fails — so you know it actually applied.
Airtel-supplied ONTs normally answer at http://192.168.1.1, and the default admin password is printed on the label underneath the unit rather than being a single value across all models. Change it on first login, because that label has been seen by the installer and by anyone who has picked the box up.
Usually not, and you should not try. TR-069 (CWMP, conventionally TCP 7547) is how Airtel provisions and updates the unit, and cutting it off can leave the ONT unmanaged or unable to reconnect after a reset. The practical control is making sure nothing else is listening on the WAN side beside it — a 2016 Mirai variant abused exposed CWMP to take roughly 900,000 Deutsche Telekom routers offline.
Because the eight-digit WPS PIN is validated in two halves, which collapses a brute force from 100 million combinations to about 11,000 — a flaw published by Stefan Viehbock in 2011 and tracked as US-CERT VU 723755. Disable WPS on both the 2.4 GHz and 5 GHz radios and join devices with the passphrase instead.
No. A hidden SSID is still broadcast by every client that looks for it, so it is trivially discoverable, and it causes connection problems on some phones and IoT devices. Rename the network to something that does not identify your ISP, model or household, keep the broadcast on, and put the effort into a long WPA2 or WPA3 passphrase instead.
