How to Enable DHCP on Chromebook?

The Chromebook is Chrome’s answer to the standard laptop or MacBook. This new notebook or laptop PC type helps you do things easier and faster with the power of the Internet. They run on Chrome OS instead of Windows or macOS.

What’s the difference? It runs on cloud storage and offers multiple layers of security. Since everything you’ll be doing is cloud-based with Chromebook, it’s especially important to know how to enable DHCP on Chromebook.

How to Enable DHCP on Chromebook

The tricky part about enabling DHCP on Chromebook is that it uses Chrome OS, which has different menus and navigation in order to access DHCP and TCP/IP settings compared to Windows.

Open “Settings” on your Chromebook. Scroll down the page then open the dropdown menu for “Name Servers”. Now connect to the network. This should result in you connecting or enabling DHCP as well.

What Happens if Your DHCP Isn’t Enabled?

If your DHCP isn’t enabled, this means your WAP (Wireless Access Point) isn’t working as a DHCP server and it’s not giving an IP address. The most obvious indication of this is you being unable to access the Internet.

In most small or home-based companies, the router serves as the DHCP server. Enable DHCP in order to connect to the Internet and automate the process of configuring devices—your Chromebook included—on IP networks.

What is DHCP?

The Dynamic Host Configuration Protocol is a network management protocol. It’s used to configure network devices to allow streamlined communication on an IP network.

The DHCP client utilizes the DHCP protocol to retrieved configuration info from places like a default route, an IP address, and a single or more DNS server addresses from a DHCP server.

In other words, this network server automatically gives and assigns default gateways, IP addresses, and other network parameters to client devices. It depends on the DHCP protocol to respond to client-side broadcast queries.

How to Fix the DHCP Lookup Error on Chromebook

A simple way of fixing the DHCP lookup error is powering off everything or power-cycling them. First off, power off or shutdown your Chromebook. Now turn off your router or modem then unplug its power cord outright.

Wait about 10 seconds and then plug the power back on both devices. Wait for the router to fully start again—it takes about 5 minutes—then start your Chromebook and check if DHCP is enabled so you’re able to browse the Internet.

Advanced DHCP Lookup Error Troubleshooting

To fix DHCP lookup error for Wi-Fi on your Chromebook as well as change other TCP/IP settings, you should first open your browser to navigate to the router’s IP address. Find the DHCP settings under the Network tab or LAN.

Set the DHCP range from 192.168.x.10 to 192.168.x.253. Keep the x-spot number the same as it currently is. Save your settings attempt reconnection to your network. See if DHCP lookup is now working.

More some ways to fix DHCP lookup failed Chromebook

Any Chromebook user knows the frustration of dealing with a “DHCP lookup failed” error message. This error can be caused by a number of factors, ranging from a weak internet connection to a faulty router. Thankfully, there are a number of steps that you can take to fix this problem.

First, check your internet connection to make sure that it is strong enough to support your Chromebook. If necessary, restart your Chromebook and forget your wireless connection. You can also use Google Name Servers or change the sleep settings of your Chromebook.

In some cases, you may need to extend the DHCP range of your wireless router or update your Chromebook. If all else fails, you can disable your WiFi extender or run Google’s Network Diagnostic Tool. If none of these solutions work, you may need to reset your router.

By following these steps, you should be able to fix the “DHCP lookup failed” error on your Chromebook.


The DHCP Reservation feature enables your router to reserve an IP address lease for use of a specific device on a given network. This ensures the router doesn’t assign this specific address to other devices within the network.

Your mostly cloud-based Chromebook by Google and its unique Chrome OS will require an enabled DHCP in order to work optimally as a mostly online type of laptop when all is said and done.
