First, log into the router's admin panel and disable the DHCP server feature.
- Connect a computer to your Orbi network (wired connection is best).
- Launch a browser and go to orbilogin.com.
- Log in with admin credentials (username: admin).
- Go to ADVANCED > Setup > LAN Setup.
- Clear the checkbox for Use Router as DHCP Server.
- Click Apply.
If that doesn't work:
- Ensure your alternative DHCP server is properly configured and active on the network before disabling the Orbi's server.
- If you disable this and have no other DHCP server, you must manually set static IP addresses on all devices to access the router.
