This page shows how to change the LAN IP Address on the Dlink DGL-3420 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 Dlink DGL-3420 LAN page you need to login to your router. If you are already logged in you can skip this step.
To login to the Dlink DGL-3420, follow our Dlink DGL-3420 Login Guide.
If you followed our login guide above then you should see this screen.
When you have finished logging into the Dlink DGL-3420 you begin on the Device Info page. When changing your IP Address, the address you can see while inside your network, click the tab at the top in orange labeled Basic. Then, on the left click LAN.
On this new page, find the box marked IP Address and enter the new address you have chosen for your Dlink Router. We highly recommend using the address of 192.168.1.1
Don't change the Default Subnet Mask. It should always remain at 255.255.255.0
Finally, save your changes, before exiting.
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.
