192.168.100.77 router login
To open the admin panel, type 192.168.100.77 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.
192.168.100.77 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 username or password is documented for 192.168.100.77, and none should be inferred from other addresses in the same subnet. If a login prompt appears, its defaults belong to the specific hardware: the label on the case is the first place to check, followed by the printed or online manual and any credentials set by the provider that supplied the unit.
How to log in to your router
Type 192.168.100.77 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 192.168.100.77, 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
Without the password, look for a documented recovery option before anything drastic, since some devices allow a local reset only within minutes of power-up. A full factory reset does work but resets everything: custom configuration is discarded, and wireless settings return to the network name and password shown on the label, so each client will need to be reconnected manually.
192.168.100.77 is a private address from 192.168.0.0/16, the range with a 255.255.0.0 mask and 65,536 addresses that consumer routers, hotspots and small office access points draw on almost universally. It falls in 192.168.100.0/24, where valid host addresses run 192.168.100.1 through 192.168.100.254 and 192.168.100.255 is the broadcast address. A further 254 addresses in the subnet are documented here.
Host 77 sits in the middle of the range, the part usually filled by DHCP rather than reserved for infrastructure, so it typically belongs to an ordinary client or a small appliance. Searches for it tend to come from someone reading a router's attached-devices screen, tracing traffic in a log, or configuring an application that was told to talk to this address and wanting to confirm what it points at.

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.
