192.168.100.1

192.168.100.1 is a block C private IP address (like any 192.168.x.x addresses). This is another address used by router and modem manufacturers as a default gateway IP address. 192.168.100.1 is rarely used but there are still a few modem and router models with this address assigned to them as a default IP. This address can also be assigned to any device within a local area network (usually within a corporate network since home routers usually have a smaller amount of available IP addresses in their DHCP pool). 192.168.100.1 can be assigned to a device within a corporate network as a dynamic IP but it can also be assigned to some devices (like printers and data servers) as a static IP.

192.168.100.1 as a Default Gateway

The default gateway is an IP address (usually class C or Class A address) assigned to devices used for accessing the internet or for connecting to other devices within a smaller network (home or local area network). Modems and routers need this addresses in order to communicate with DNS servers and all the other devices within a network.

This is not the only function of a default gateway. This address is important for us (users) and we have to know it in order to change all kinds of network settings and to configure our modems and routers. Whether you want to change SSID and network password, router’s default username and password, allow or forbid access to some websites or users or even improve internet speed, you have to use this address.

How to Access Router Setup Page?

In order to open the setup page, you need to type in 192.168.100.1 in the address bar of your browser. When the login page opens, you have to enter router’s username and password (usually admin-admin for Motorola modems and routers, and root-admin for Huawei modems and routers). After entering the right words, the setup (configuration) page will open.

The setup page will look like this

Huawei modems and routers

Motorola (ARRIS) modems and routers

Note: Before changing anything be aware of what the specific change brings. Things you should definitely do during the initial setup are changing router’s and network’s name and password (in order to improve the security of your router and your network and prevent other people from using your internet connection).

You can find tutorials explaining every step of the process of changing passwords in one of our previous articles. The interface of the routers in that article is maybe different from the interface of these routers but the procedure is basically the same.

What if You Can’t Access the Setup Page?

This happens sometimes and there are a couple of reasons:

Reason 1 – 192.168.100.1 is not your router’s default IP address. There’s a way to check the default gateway (default IP) on every OS. You can read about that here.

Reason 2 – Incorrect router’s username or password. There’s s a few possible solutions (reading the instructions manual, looking for help online, trying some other common usernames and passwords, resetting the router). A detailed explanation can be found here.

Reason 3 – IP conflict. If there is some device with static IP assigned to it and if that static IP is the same as the default IP address of the router, the IP conflict will appear. This conflict will cause modem or router to stop working as intended. In order to solve the conflict, you have to assign a different IP address to the device with static IP. You can find the instructions on how to assign a static IP address to your computer here.

192.168.100.1 as a Host IP Address

As we have mentioned previously, 192.168.100.1 can be assigned to any device within a corporate network. This address can be static or dynamic (static is usually assigned to printers and data servers). The only thing you should pay attention to when assigning static IP to some device is your router’s default IP. You should avoid assigning router’s IP to your device in order to evade an IP conflict.
