What is the LAN IP Address of a 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:
- 192.168.0.1
- 192.168.1.1
- 10.0.0.1
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.

If you followed our login guide above then you should see this screen.
Now that you have finished logging into the Tecom AH4021 you see the Device Info page for this Router. To change your Router IP Address or the address you see from the inside of your network, click the choice on the left side bar labeled Advanced Setup. Under this heading more choices appear, click the one labeled LAN.
Configure the LAN section of your Tecom AH4021
You should now be on the Device Setup page of your Router. Place your cursor in the box labeled IP Address and enter the new address you have chosen for your Router. One good suggestion is the address of 192.168.0.1
Make sure that while you make this change, you do not change the Subnet Mask, this should remain as it is, 255.255.0.0
You need to also leave the DHCP Server enabled, this allows the Router to automatically choose from a group of addresses for you when needed.
When you have finished, click Next.
Possible Problems when Changing your LAN IP Address
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.
