This page shows how to change the LAN IP Address on the Buffalo WHR-HP-G54-Tomato router.
The LAN IP Address of a router is also known as its internal IP address. It is also the IP address that you connect to when you want to configure your router. It is only useful from inside your network and has no use from the Internet side.
Routers have 2 IP addresses: an internal ip address and an external ip address. The external IP address is assigned to you by your Internet Service Provider, or ISP, and is generally not something that you can change. The internal IP address is set to a default value at the factory but can be changed if you want.
Common internal IP addresses for routers are:
It is generally a good idea to make the last number of your router's internal IP address a '1', as in 192.168.0.1 or 10.0.0.1. This is not necessary, but many people do it and it makes it a bit easier to remember which IP address is assigned to your router. If you want to change the internal IP address of your router, this guide shows you how.
To get started configuring the Buffalo WHR-HP-G54-Tomato LAN page you need to login to your router. If you are already logged in you can skip this step.
To login to the Buffalo WHR-HP-G54-Tomato, follow our Buffalo WHR-HP-G54-Tomato Login Guide.
If you followed our login guide above then you should see this screen.
Once you have logged into the Buffalo WHR-HP-G54 Tomato you begin on the Status page. To change your IP Address, the address you see from inside your network, click the choice on the left labeled Basic. This opens up more options below, choose the one labeled Network.
Scroll down this new page until you come to the LAN section. Click the box labeled Router IP Address and enter the new address you have chosen here. We would like to recommend using the address of 192.168.1.1
Do not change the Subnet Mask which should remain at 255.255.255.0 or the DHCP Server which should remain on.
Click Save at the bottom of the page for these changes to take effect.
When you change your LAN IP Address you are making a fundamental change to how your network functions and all computers on your network will be affected. You will lose your Internet connection when you apply these changes. Your router may reboot and require a couple of minutes to start responding again.
Also note that some computers may need to be rebooted after you make this change before they can talk to the router or on the Internet again.
