How to change DHCP settings on your modem

Dynamic Host Configuration Protocol (DHCP) settings allow you to set the parameters for how your modem assigns IP addresses to devices on your network.

Proceed with caution! CenturyLink recommends that you keep the default settings for the LAN IP address. Changes to this feature will reset other settings on your modem as well. Proceed only if you understand the technical impacts of this feature.

If you need to restore the default CenturyLink IP addressing values, they are:

DHCP Server: Enable
Modem IP Address: 192.168.0.1
Beginning DHCP Server Address: 192.168.0.2
Ending DHCP Server Address: 192.168.0.254
Subnet mask: 255.255.255.0

NOTE: This article applies to newer CenturyLink modems. Depending on your particular model, you may see slight differences in the features or layout of your modem's user interface.

1. Connect a device, such as a computer or tablet, to the internet through WiFi or using an Ethernet cable connected to your modem.

2. Open a web browser and type http://192.168.0.1 into the web address field.

Enter the URL for the modem user interface

3. Log in to the modem's settings interface (Modem GUI) using your Admin Username and Admin Password. Note that these are different from your wireless network name (SSID) and WiFi password (security key).

Find the Admin Username & Password on the modem sticker

Log into the modem interface with the Administrator Username and Password

4. Select the Advanced Setup icon in the main menu.

5. Select "DHCP Settings" in the left sidebar. This menu option may appear in the LAN Settings section or in the IP Addressing section, depending on your model.
