Question

How do I change the Gateway IP Address on my G34/G36?

Answer

The G34/G36 gateway's default IP address 192.168.0.1 is used for accessing the Web Manager, and the DHCP server assigns private IP addresses (192.168.0.2 - 192.168.0.254) to client devices in the home network. The gateway's IP address can be customized to match the previous IP address scheme of the home network. When the gateway IP address is changed, the DHCP server assigns the new private IP addresses to the client devices in the home network.
