Before the upgrade, everything was working perfectly. After upgrading to firmware v1.10, the ONT no longer initializes the LAN port correctly after every reboot.

Network Setup

• Airtel Fibre connection
• XC220-G3v used as ONT
• A router is connected to one of the LAN ports of the XC220-G3v

Problem

Whenever the XC220-G3v reboots:

• The router connected to the LAN port shows the WAN connection as disconnected.
• The LAN port appears to be inactive or not properly initialized.
• Internet connectivity is not restored automatically.

Temporary Workaround

To restore connectivity, I have to:

1. Log in to the XC220-G3v web interface.
2. Go to Advanced → Network → Internet.
3. Click Modify on the current Internet connection.
4. Toggle the LAN port assignment (Check & Uncheck)
5. Save the settings.

Immediately after doing this, the LAN port becomes active and the router regains Internet connectivity.

Troubleshooting Performed

• Multiple reboots tested.
• Factory reset performed.
• Ethernet cable replaced, also tried different LAN ports
