Disable DHCP

This topic describes how to disable DHCP to prevent the router from automatically assigning IP addresses to devices that connect to the RMH network.

Disabling DHCP (Dynamic Host Configuration Protocol) prevents the router from automatically assigning IP addresses to devices that connect to the network. Disabling DHCP secures the network by preventing merchants or unknown third parties from plugging unauthorized computers or devices into the network.

Disabling DHCP will disconnect all store computers and peripheral devices from the network. You will need to assign static IP addresses to these computer or device to reconnect them to the network.

The exact procedure for disabling DHCP will vary depending on the type of router you have installed in the store. Follow the configuration instructions provided by the manufacturer of the router that you are using.

The HighSpeed.Tips (https://highspeed.tips/) web site provides links to demo web clients (emulators) for a variety of modems and network routers. You can use the emulators to familiarize yourself with the web client configuration options for devices from a range of hardware manufacturers.

The procedure below is provided as an example. It is based on Netgear's Genie router.

1. On the Advanced tab, expand Setup.

2. Click LAN Setup.

3. Clear the check mark beside Use Router as DHCP Server.

1. Click Apply.
