How to open 192.168.100.1
If your cable modem exposes a local page at 192.168.100.1, the access path is usually simple.
- Stay connected to your home network or to the modem as your vendor recommends.
- Open your browser.
- Type http://192.168.100.1 in the address bar.
- Press Enter.
- If a login page appears, enter the modem credentials. If a status page appears, you can review the available information.
http://192.168.100.1This page may behave differently from a router login. Some modems show status information first; others ask for credentials.
What to do if 192.168.100.1 does not load
Not every network setup exposes this local modem page in the same way. If the browser cannot open it, start with the simplest causes:
- Your modem model does not use 192.168.100.1 for local access.
- Your router is not passing access through to the modem local page.
- You typed the IP into search instead of the browser address bar.
- Your browser is forcing HTTPS while the address only answers on http://.
- You are actually looking for the router admin page, not the modem page.
- Try again with http://192.168.100.1.
- Check your router gateway from your device.
- Try 192.168.1.1, 192.168.0.1, or 192.168.1.254 if you are looking for the router.
- Check the modem label or documentation to confirm the correct local address.
Best clue: if you want to change Wi-Fi settings, you usually need your router gateway. If you want modem status, 192.168.100.1 may be the right page.
How to know if you are on the modem or router page
A modem page usually focuses on the connection between your home and the provider network. A router page usually focuses on your local network, Wi-Fi name, Wi-Fi password, DHCP, guest network, and connected devices.
It looks like a modem page
You see signal levels, cable status, downstream, upstream, modem logs, or provider connection details.
It looks like a router page
You see Wi-Fi settings, DHCP, local devices, port forwarding, guest network, or router administration options.
Before resetting the modem
A page that does not load does not automatically mean you should reset the equipment. A reset can remove useful settings. Before doing that, check that you are using the right address, that you are on the right network, and that you are looking for the modem page rather than the router page.
Simple rule: if Internet works but 192.168.100.1 does not open, the issue may simply be the address, the model, or the network path to the modem.
Modem username and password
There is no universal login for 192.168.100.1. The credentials depend on the modem brand and model. Some vendor examples are:
| Example | Username | Password |
|---|---|---|
| Some Motorola cable modems | admin | motorola |
| Some NETGEAR cable modems | admin | password |
Treat those as model-specific examples, not as universal credentials. Check your modem label or the manufacturer documentation for your exact device.
Security note: if your modem allows changing admin credentials, avoid keeping factory defaults.
