About these network details

Your browser automatically queries ipdata for public IP, network and approximate location, and ip-api for the observed DNS resolver. Local IP and device count cannot be reliably detected. Results may be cached for 10 minutes.

Defaults vary by model and firmware. A dash is a database value, not a guarantee of an empty password. Check your device label first. Historical directory entries have not been individually confirmed against model manuals.

The complete 169.254.100.100 guide

169.254.100.100 is an IPv4 link-local address recorded for equipment in our device directory. Use it only after confirming the exact model and the local connection required by its documentation.

What to check at 169.254.100.100

This is an IPv4 link-local address, not an RFC 1918 private gateway address. Link-local communication stays on the local link and is not forwarded by routers. A computer displaying its own 169.254 address may have failed to obtain a DHCP lease; that alone does not mean a device exists at 169.254.100.100. Follow the exact model's local-management instructions.

Devices listed with this address

Our directory associates 169.254.100.100 with NETGEAR. Example model records include NETGEAR FSM7226RS, NETGEAR FSM7250RS, NETGEAR FSM726, NETGEAR FSM726E. These are recorded defaults, not a live scan of your network or a guarantee for every hardware revision. Compare the complete label and the current configuration before selecting a credential.

Connect to the correct network

Use the same local link as the target device, following the model-specific instructions for cabling and addressing. Your normal Internet gateway cannot route traffic to this link-local destination. Do not confuse a computer assigning itself a 169.254 address with discovery of the target device.

If normal Internet connectivity has also stopped, check the Ethernet link, Wi-Fi association and DHCP service separately. Recovering the normal connection and opening a documented link-local management interface are different tasks.

Open the management page

  1. Enter http://169.254.100.100 in the browser address bar. Do not enter it in a search box or add extra dots.
  2. If the model documentation specifies HTTPS or a particular management port, use that exact documented URL instead.
  3. Check the product identity on the sign-in page before entering credentials. A certificate warning requires checking the device and certificate; do not automatically ignore it.
  4. Use your saved administrator password or the model-specific setup instructions. The administrator password and the Wi-Fi password serve different purposes.

If 169.254.100.100 does not open

A timeout happens before authentication and does not prove that your password is incorrect. Confirm the current address from the device label, saved configuration or the upstream router’s client list. The default gateway is useful for a primary router, but it may point to another unit when the target is an access point, bridge or modem.

Try a direct Ethernet connection where supported. Check whether a VPN route, guest isolation or management access rule prevents local access. On a managed network, ask the administrator to confirm the permitted path. Internet access working elsewhere does not guarantee that this particular management service is enabled.

Credentials and configuration changes

Use the matching brand page above to locate your exact model and revision. Directory values describe initial or recorded defaults; they do not recover a password that someone changed. A dash or an empty field means the record is incomplete, not that a blank login was tested.

Once signed in, back up the configuration if the device supports it and make one change at a time. Keep the original LAN address and provider connection details available. A LAN-address change can close the current session; a Wi-Fi change can disconnect wireless clients. Reconnect using the new settings.

When to consider a reset

Restarting preserves configuration; a factory reset normally removes customized settings. Use a reset only after checking the exact model procedure and confirming that you can restore the Internet connection and administrator access. Contact the provider or configuration owner first for managed equipment.
