192.168.100.45 router login

To open the admin panel, type 192.168.100.45 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.

192.168.100.45 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 is recorded for 192.168.100.45. Given that the address usually belongs to a client device rather than a router, there may be no administrative login behind it in the first place.

When a login prompt does appear, identify the hardware before trying anything. The shipped account is normally printed on a label attached to the device, listed in its manual, or set during first-run setup in a companion app. Modems and gateways supplied by an internet provider often have credentials documented in the subscriber account rather than on the case.

How to log in to your router

  1. Type 192.168.100.45 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 192.168.100.45, 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

Work out what holds the address first. Resetting a client device clears its own configuration — saved networks, linked accounts, stored media or recordings — without affecting the router. Resetting the router because a client is unreachable is a much larger cost: wireless names and keys, port forwarding, reservations and provider settings all revert.

Gentler remedies usually work here. Renew or release the DHCP lease, power-cycle the device, or check the router's client table to see whether the lease simply moved to a different address before considering any factory restore.

192.168.100.45 comes from 192.168.0.0/16, the private range consumers meet most. Its 255.255.0.0 netmask covers 65,536 addresses, and it earned that familiarity because home routers, mobile hotspots and small office access points nearly all ship default gateways inside it. As private space it is unallocated and endlessly reusable, so the number reveals nothing about a provider, an owner or a country.

The subnet in question is 192.168.100.0/24, with usable addresses from 192.168.100.1 to 192.168.100.254 and 192.168.100.255 as broadcast. At position 45 this address sits inside the region a DHCP server typically hands out, not at the .1 or .254 ends where gateways are conventionally placed. Devices found here are usually clients: computers, phones, smart displays, media boxes or IP cameras that were assigned a lease, or occasionally something pinned to a fixed address within the pool.

The 192.168.100.0/24 range has a second life as the management segment used by many cable and DSL modems in bridge mode, which is why it is looked up more often than its neighbours. Every one of the other 254 addresses in this /24 is documented here, making it one of the more thoroughly mapped segments on the site.

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.
