192.168.100.4 router login

To open the admin panel, type 192.168.100.4 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.

192.168.100.4 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.

No default username and password pair is documented for 192.168.100.4, and no specific vendor is known to ship this address, so there is no credential set that can honestly be quoted for it. A private address is only a position on a network; the login belongs to whichever device happens to hold it.

Look for the device's own defaults on the label printed on its underside, back or a pull-out card, where they are commonly shown beside the serial number and default network name. Otherwise check the quick-start guide, the support page for that exact model, or, for provider-supplied equipment, the documentation from the internet provider. Many current devices require you to set your own password during first setup, in which case no factory pair exists at all.

How to log in to your router

  1. Type 192.168.100.4 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 192.168.100.4, 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

If the login is refused, work through the softer options first: credentials saved in a browser or password manager, anyone else who administers the network, and any configuration backup exported earlier. A factory reset is a last resort because it is not free. It clears the Wi-Fi name and password, port forwarding, DHCP reservations — including whatever pinned a device at 192.168.100.4 — firewall rules and any provider or PPPoE credentials, and the device may reappear on a different address afterwards.

Since no specific vendor is known for this address, follow the reset procedure in the manual for the model in front of you. Commonly it is a recessed button held with a pin for roughly ten to thirty seconds while the unit is powered.

192.168.100.4 is a private IPv4 address inside 192.168.0.0/16, the RFC 1918 range that carries the netmask 255.255.0.0 and holds 65,536 addresses. It is the block most people encounter, because nearly every home router, mobile hotspot and small office access point ships a default gateway somewhere inside it. Addresses here are never routed across the public internet, and the same numbers are in use on millions of separate networks at once, so the address by itself indicates no location, no internet provider and no owner. It has meaning only on the network you are currently attached to.

Within that block the address falls in the subnet 192.168.100.0/24, whose usable range runs from 192.168.100.1 to 192.168.100.254, with 192.168.100.255 reserved as the broadcast address. 192.168.100.4 is the fourth usable position, not one of the slots a gateway commonly occupies; routers are far more often found at .1 or .254. A low fixed address like this more typically belongs to equipment sitting behind the gateway, such as a modem management interface, an access point, a printer, a camera or a storage device.

Most people looking this address up are trying to open a web interface at http://192.168.100.4 after seeing the number on a device label, in a router's client list or in their own network settings, and want to know what answers there and how to sign in.

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.
