How do I set up a DHCP Server in my Orbi RBR40 router?

The Dynamic Host configuration Protocol Reservation, also known as the DHCP reservation feature, allows the user to reserve an IP address for a specific device on your network. It ensures the router does not assign the same IP address to other devices in the network. The DHCP feature allows multiple devices to be managed by your Wi-Fi router. When you set up a DHCP server with your Orbi RBR40 router, you can manage multiple devices, such as a printer, servers, web cameras, network printers, and other gaming consoles.

Important Note: Ensure that the IP address that you are going to assign to the Orbi login RBR40 device is within the DHCP Reservation range. You cannot set an IP address outside the DHCP range after configuration.

A quick tip: It is better to enable the DHCP Server because disabling it will convert your Orbi setup RBR40 router as a switch. It means you can allow internet access to only one computer. If you assign the IP address to disable the DHCP server range, it will be the network address translation. NAT helps to translate these IP addresses of the modem and the router.

If you have set up the DHCP server in your router by default, the router will assign IP, DNS servers, and the default Netgear password, gateway addresses to all devices associated with the LAN port. The gateway IP address is the default LAN address for the Orbi admin login process in your RBR40 router.

You can either use a different device on your network as the DHCP server or specify the Orbi Netgear login network settings of all your devices connected to the LAN port.
