192.168.100.109 router login
To open the admin panel, type 192.168.100.109 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.
192.168.100.109 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.
Nothing in the way of default credentials is documented for 192.168.100.109, and no product is known to claim it, so any published pair would be invention. Where the address does front a manageable device, its own defaults are printed on the case label or bundled paperwork; ISP-supplied hardware often carries a per-unit password rather than a shared one.
How to log in to your router
Type 192.168.100.109 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.
If the browser reports that it cannot reach 192.168.100.109, 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".
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
When the password is lost, a factory reset is the last resort rather than the first move. It clears every change made since installation, including SSID changes, firewall rules, VLAN settings and reservations, and drops the administrator password back to whatever the label states. Wi-Fi credentials return to the printed defaults too, so plan to reconnect each device afterwards.
This address belongs to 192.168.0.0/16, a private range of 65,536 addresses under the 255.255.0.0 netmask. Because RFC 1918 space is reusable by anyone, 192.168.100.109 carries no registrant, owner or geography; it is meaningful only inside whichever local network you happen to be on. The block is the consumer one, the range home routers, hotspots and small office access points draw their default gateways from.
The surrounding /24 is 192.168.100.0/24, hosts 192.168.100.1 through 192.168.100.254, broadcast 192.168.100.255. The third octet of 100 is a common choice for a segment kept separate from a main LAN, and .109 is host number 109 in it, a position DHCP pools reach easily. Visitors typically arrive after spotting the address in a device list, a log line or a printer's network settings, and want to establish whether it is a gateway worth logging into or simply another client.

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.
Comment:
Comment: These addresses can be used by anyone without any need to coordinate with IANA or an Internet registry. The traffic from these addresses does not come from ICANN or IANA.
