Changing Default LAN IP Address in Vigor2860/Vigor2925
Posted by Roy Panetta on 23 October 2014 11:45 AM

This guide will show you how to change the default LAN IP address for a LAN if the new IP address conflicts with an existing IP address for another LAN in the router. The router will have pre-configured default LAN settings.


This document that shows the steps required to change LAN1 subnet to 192.168.2.1.
By default LAN2 uses 192.168.2.1 so we need to change LAN2 settings first before we can change LAN1.
In the process we need to enable VLANS. Make the changes and then disable VLANs when finished.

Step 1: Enable VLAN setting

 

Go to LAN>>VLAN Configuration menu

 

Assign all the LAN ports and Wi-Fi LANS to a VLAN and save settings

 

Note: you will need to assign all LAN ports and SSID’s to a VLAN or the configuration cannot be saved.
