How to Login to 192.168.100.1

Managing Your Modem/Router: 192.168.100.1 often serves as the entry point to the configuration and diagnostic interface of cable modems, particularly popular Motorola (Arris) Surfboard models, as well as some routers from brands like Huawei.

Accessing this interface allows you to check connection status, view logs, and sometimes configure basic settings (though many settings might be controlled by your ISP on modems). Ensure your computer is connected directly to the modem/router, ideally via an Ethernet cable, especially when checking modem diagnostics.

A direct Ethernet connection bypasses any intermediate network devices and is recommended for accessing modem interfaces. Use a standard web browser like Chrome, Firefox, or Edge.

Note that for cable modems, the available configuration options might be limited compared to a full router.

  1. Connect your computer directly to the modem or router using an Ethernet cable.
  2. Open a web browser on the connected computer.
  3. Enter 'http://192.168.100.1' or 'http://192.168.100.1' in the address bar.
  4. Press Enter to load the login page.
  5. Provide the default username and password (e.g., 'admin'/'password', 'admin'/'motorola', check device label/manual).
  6. Click 'Login' or 'Submit' to access the interface.

Troubleshooting Issues with 192.168.100.1

If 192.168.100.1 isn't loading, review these points:

  • Direct Connection Required: Ensure you are connected *directly* to the modem/router associated with this IP, not through another router or switch.

  • IP Address Check: Verify your computer has obtained an IP address from the device (usually 192.168.100.x).
  • Typo Verification: Double-check the IP address entry for errors.
  • Power Cycle Modem/Router: Restart the device by unplugging it for a minute, then plugging it back in. Wait for it to fully boot up.
  • Browser Cache/Incognito: Clear your browser's cache or attempt access using an incognito/private window.
  • Firewall Block: Temporarily disable any software firewall on your computer.
  • Check Device Manual: Confirm 192.168.100.1 is indeed the correct default IP for your specific model. Some devices use different IPs.
  • Factory Reset (Caution): Resetting a modem might require reprovisioning by your ISP. Resetting a router will erase its settings. Use the reset button as a last resort.
