192.168.100.25 router login

http://192.168.100.25 ↗

To open the admin panel, type 192.168.100.25 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.

192.168.100.25 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.

The credential record for 192.168.100.25 is empty, so no username and password will be stated. The correct defaults come from the device holding the address, and they differ from product to product even within a single manufacturer's range. Look for a printed label on the underside, rear or inside panel of the unit, which normally carries the administrative account and its initial password. Where that has been removed, the printed setup guide, the model's official manual, or your internet provider's documentation for equipment they installed are the places to check.

How to log in to your router

  1. Type 192.168.100.25 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 192.168.100.25, 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

Since addresses in a 192.168.100.0/24 segment frequently belong to something sitting between your router and the wider network, be careful about resetting blindly; you may take down connectivity for everything behind it. A factory reset clears all configuration, including the addressing that placed the device in this subnet, wireless settings, forwarding and firewall rules and any provisioning applied after installation, and the device will return on its manufacturer's default address. The usual mechanism is a recessed button held for approximately ten to thirty seconds with power connected.

192.168.100.25 sits inside 192.168.0.0/16, the RFC 1918 block of 65,536 private addresses carried under the mask 255.255.0.0. This is the consumer block, the one nearly every home router, hotspot and small office access point uses for its default gateway, and the one most people therefore encounter. Addresses in it are private in the strict sense: they are not routed on the public internet and can be reused freely on any number of unconnected networks.

The relevant subnet is 192.168.100.0/24, usable from 192.168.100.1 to 192.168.100.254 with 192.168.100.255 reserved for broadcast. A third octet of 100 is a common choice for a secondary or separated network, for example a management segment, a guest network, or a modem's own interface kept apart from the router's LAN, so the subnet often shows up alongside a different range rather than on its own. Position 25 is a host slot rather than a gateway slot.

People arriving here are typically trying to reach a device on a secondary segment, or working out why an address in this subnet appeared on a network they thought used a different range.

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.
