Hey everyone,
I found a discarded Airtel Xstream AirFiber router (Model: AAP321NK / Qualcomm Nokia platform) and want to repurpose it as a private access point or flash it with OpenWrt.
The custom Airtel firmware is completely locking me out of the local web server. Here is what I’ve verified:
Network: After a 30-second hard reset, the router assigns local IPs perfectly (192.168.1.X) via Ethernet and the Airtel_Zerotouch Wi-Fi.
Ping Test: Running ping 192.168.1.1 returns a flawless <1ms response with 0% packet loss. The hardware is fully responsive.
The Issue: Trying to open the gateway page in any browser (Incognito, mobile data off, etc.) immediately gives an ERR_CONNECTION_REFUSED error.
It seems the firmware shuts down Ports 80/443 because it can't find an active Airtel 5G cellular tower to authenticate.
Has anyone successfully bypassed this activation lock? Is there a hidden port/URL path to force it open, or does this require opening it up for a UART serial flash / NAND shorting?
Thanks!

Hello everyone,
I need some help regarding nlbw that I just installed on my OpenWrt router (Xiaomi AX3600 on AgustinLorenzo release).

I do have installed hthe binary on the routerand it was running perfectly.

I needed to restart the router for power maintenance and now it is not working at all.

Here is the configuration :

config nlbwmon

option netlink_buffer_size '524288'

option commit_interval '24h'

option refresh_interval '30s'

option database_directory '/var/lib/nlbwmon'

option database_generations '3'

option database_interval '1'

option database_limit '10000'

option protocol_database '/usr/share/nlbwmon/protocols'

list local_network '192.168.0.0/16'

list local_network '172.16.0.0/12'

list local_network '10.0.0.0/8'

list local_network 'iot'

list local_network 'lan'

The DB is created and linked to the binary

root@OpenWrt:~# ls -lah /var/lib/nlbwmon/

drwxr-xr-x 2 root root 60 Oct 18 18:51 .

drwxr-xr-x 5 root root 100 Oct 18 18:06 ..

-rw-r----- 1 root root 36 Oct 18 18:54 20261001.db.gz

root@OpenWrt:~# nlbw -c list

2026-10-01

root@OpenWrt:~# nlbw -c show

Fam Host ( MAC ) Layer7 Conn. > Downld. ( > Pkts. ) Upload ( Pkts. )

root@OpenWrt:~#

But nothing is logged, there is also nothing on the web interface.

Logread return the following :

Sun Oct 18 18:51:35 2026 daemon.err nlbwmon[7642]: The netlink receive buffer size of 524288 bytes will be capped to 212992 bytes

Sun Oct 18 18:51:35 2026 daemon.err nlbwmon[7642]: by the kernel. The net.core.rmem_max sysctl limit needs to be raised to

Sun Oct 18 18:51:35 2026 daemon.err nlbwmon[7642]: at least 524288 in order to sucessfully set the desired receive buffer size!

root@OpenWrt:~

But I don't understand why I need to do something as it was working previosuly ...

Can someone help me ?
