192.168.100.123 router login

To open the admin panel, type 192.168.100.123 into your browser's address bar. If the page does not load, this is probably not the gateway address on your network — see the checks below.

192.168.100.123 router passwords

Where to find them:

  • The label on the underside or back of the router — most manufacturers print the default admin username, password and Wi-Fi key there.
  • The quick-start card or manual that came in the box.
  • Your ISP's account portal, if the device was supplied by them — many set a unique password per line rather than a shared default.

There is no recorded default username and password combination for anything answering on 192.168.100.123, so no pair can honestly be offered. Read the credentials off the printed label on the underside or rear of the hardware, from the quick-start sheet, or from documentation your internet provider supplied if the equipment came from them. Many units force a password change during first setup.

How to log in to your router

  1. Type 192.168.100.123 into your browser's address bar and press Enter. Type it by hand rather than accepting an autocomplete suggestion, which often fills in a different address you visited before.

  2. If the browser reports that it cannot reach 192.168.100.123, this is not the gateway address on your network. On Windows run ipconfig /all and read the Default Gateway line; on macOS open System Settings, Network, Details, TCP/IP; on Linux run ip route and read the address after "default via".

  3. If the login page loads but rejects your credentials, and you have never changed them, use the defaults printed on the device's label. If they have been changed and nobody knows the new password, a factory reset is the only way back in.

If you do not know the password

Before resetting, confirm the device really is the one you need to reach, since a middle-of-range lease can move between devices. If the password is genuinely lost, holding the reset pinhole restores factory defaults, which means losing port forwards, DHCP reservations, parental controls and guest networks, and seeing the Wi-Fi name and key revert to whatever the label shows.

This address is part of 192.168.0.0/16, the private range consumer networking gear leans on most heavily. The block spans 65,536 addresses behind a 255.255.0.0 mask, and its familiarity comes from the sheer number of home routers, hotspots and small office access points that default into it.

192.168.100.0/24 is the local segment here: usable hosts run from 192.168.100.1 to 192.168.100.254, and 192.168.100.255 is the broadcast address. Position 123 falls squarely in the middle of the range, the sort of number a DHCP server issues in sequence as devices join, which makes a dynamic lease more likely than a fixed gateway. People usually look this address up after it appeared in a client list or a management interface and they cannot place which device it is.

The full 254 host addresses of this /24 are documented separately.

Comment: These addresses are in use by many millions of independently operated networks, which might be as small as a single computer connected to a home gateway, and are automatically configured in hundreds of millions of devices. They are only intended for use within a private context and traffic that needs to cross the Internet will need to use a different, unique address.
