How to restart and refresh the IP address of the optical splitter

Power Cycle Method
- Unplug the power cord from the optical splitter or ONT.
- Wait about 30 seconds to allow residual power to discharge.
- Plug the power cord back in and wait a few minutes for the device to fully boot and reconnect to your ISP's network .
Reset Button Method
- Locate the small reset button on the ONT (usually on the back or bottom).
- Press and hold the button for 10–15 seconds using a paper clip or pin.
- Release the button and wait for the ONT to restart. This restores default network settings and can resolve configuration conflicts .

Via Router or ONT DHCP
- Most ONTs receive IP addresses automatically from your ISP's DHCP server. Restarting the ONT or router often triggers a new IP assignment .
Using a Computer on the Network
- On Windows:
  - Open Command Prompt as Administrator.
  - Type ipconfig /release and press Enter to release the current IP.
  - Type ipconfig /renew and press Enter to request a new IP from the DHCP server.
  - Type ipconfig to verify the new IP address .
- On macOS or Linux, similar commands (sudo dhclient -r and sudo dhclient) can release and renew the IP.

Check Power and Connections: Ensure the ONT is receiving power and all fiber connections are secure .
ISP Support: If restarting and refreshing the IP does not restore connectivity, contact your ISP, as some optical splitters may require remote provisioning to assign a new public IP .
Backup Settings: If your ONT has custom configurations, note them before performing a reset to avoid losing network settings . By following these steps, you can effectively restart your optical splitter and refresh its IP address, resolving most connectivity issues and ensuring a stable network connection.
