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, one of these points may explain it:
- Your modem model does not use 192.168.100.1 for local access.
- Your router or network setup is not allowing the page to be reached in the expected way.
- You typed the IP into search instead of the browser address bar.
- You are actually looking for the router admin page, not the modem page.
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.
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.
