Devices and brands using the 192.168.100.1 router IP
Many routers set 192.168.100.1 as the IP address used to log in to the router's admin page. This IP is commonly used by Motorola, Zyxel, Arris, Netgear (especially cable modems), TP‑Link, Huawei, among others, as the default admin gateway. It’s particularly prevalent in modem-router combo units.
From the admin page for these routers, you can change passwords, change access or users, and more, including LAN, WAN, WLAN settings; security settings; DNS settings; and the WiFi SSID, which is the name of the WiFi network.
Understanding the 192.168.100.1 IP
Note that all octets in this IP are numerical; there are no letters or special characters in this IPv4 address. Do not add spaces like 192.168. 100.1 or 192.168 100.1, or characters, like 192.168.100.1/.
The login URL is http://192.168.100.1, not htlp://192.168.100.1 or http //192.168.I.100.1. Notice the 'l' where a 't' should be for http to work. Entering htlp://192.168.100.1 will not take you to the correct location.
Do not remove any dots that separate the octets, like 192.168.1001, 102 168 100 1, and 1921681001. This makes it an incomplete IP address, which could result in a no-response message.
What is the 192.168.100.1 username and password?
admin/admin is the most common router login and router password. However, that depends on the type of router. Other popular username and password combinations are admin/Admin, admin/password, and admin/1234. These router default logins and passwords are case sensitive. You can check out the list of common router logins if you aren't sure what your login might be.
If you have forgotten or can't find the login or password for your router, perform a factory reset on the router. Locate the reset button on the back of the router and press it for a few seconds until the lights on your router blink. Once your router has rebooted, the factory default username and password will be in place again.
Note that resetting the router using the reset button will erase any custom configuration and put the router back to factory settings. If you had previously setup port forwarding for security cameras or other devices you wanted access to while connecting to your router remotely, these router settings will need to be reapplied.
Changing default username and password
The first thing you should do once you’re on the admin page is change your default router password to a new, secure password as most default passwords are the same. Leaving the default router or WiFi password makes your router, modem, and home network vulnerable to hackers.
Changing the 192.168.100.1 SSID
Access the router and from the settings page, you can change the SSID, which is the WiFi network name. It’s a good idea to change the name to something easily recognizable that will stand out from other networks. This is especially helpful if your neighbors have the same ISP default network names.
Furthermore, if you frequently have guests at your house, it’s a good idea to set up a separate guest SSID. This keeps guests on a different WiFi network in your home, preventing the spread of malware or other technical issues to your devices on your network. It also protects your WiFi password.
