A DHCP Server is a network server that automatically assigns client devices with IP addresses, default gateways, and other network parameters. It relies on the standard protocol known as Dynamic Host Configuration Protocol or DHCP to react to broadcast queries by clients. This protocol makes it possible for the system to use various UDP and TCP-based network services, such as DNS and NTP. The DHCP lookup failed error can be caused by an obsolete OS, damaged router firmware, invalid frequency, and a secret SSID
. DHCP lookup failed, which means Chromebook was not assigned the IP address. Networks can at times have queer issues. One such issue is the failure of the DHCP search. It appears primarily as a message. Knowing how to fix stuff like that can be pretty useful.

Decoding The DHCP Lookup Failed Obstacle
This includes a message to show that the DHCP is unable to allocate an IP. It blocks the site, therefore, from the network. The address pc/laptop have in that case is 220.127.116.11.0. It is the one reserved for failed mistakes and the likes of the DHCP quest.
How To Fix The DHCP Lookup Failed Error?
There are few things that we need to check and be sure of before going to advance troubleshooting. Often we can only need to stop a few items that may solve our problem or get rid of them.
- Ensuring to have an active internet connection.
- Try connecting to another WiFi network.
- It could be designed to operate on a certain network if you are using some Chromebook or any agency or business like it. You should contact the system administrator if that is the case.
- Tap on the Status field, then click the Slider button to pick WiFi Network, Disable and Activate WiFi.
To fix the DHCP lookup failed on Chromebook, we have to follow the methods mentioned below:
Restarting Chromebook and Router
Many times, we have found that the WiFi extender and repeater are the real culprits of a failed Chromebook error behind the DHCP quest. A temporary device or communication glitch could be the cause of the DHCP error. A simple restart of the router would not be sufficient. We need to perform a proper power reset procedure while restarting.
- Make your Chromebook Shut Down (not just sleep by closing the lid).
- Power up and unplug your modem/router from the power source.
- Until plugging everything back to the power source, wait 30 seconds.
- Wait until the lights in the modem/router are stabilized.
- Turn on the Chromebook now, and link your device to the WiFi network later to check if the error is obvious.
Change Router Settings
Router settings may also be one of the reasons why Chromebooks struggled to scan for DHCP. It may be that the WiFi router you are using is working with your other computers, but Chromebook doesn’t work, and you receive an error message.
- Open Settings of your Chromebook.
- Now click on the device and then hit Power.
- Next, open the dropdown of When Idle in which you’ll select Turn off Display but Stay Awake.
- Open the dropdown list of When Lid is Closed and choose to Stay Awake.
- Simply save your changes and exit the Settings.
- Lastly, restart your device and connect to the network to check if it is clear of the DHCP lookup failed error.
Using Google Name Servers
If the system cannot communicate between the server and the IP address, then the DNS server is the primary reason. The system fails to query a DNS server and shows the error in the DHCP lookup. This is why the best thing to do is to use Google Name servers.
- To open the update menu, click on the time icon in the taskbar’s lower right corner. Now, by clicking on the gear icon, open the Chrome settings.
- Under the Network section, select the WiFi option. Click the network’s right-click arrow, which faces an error when linking.
- Scroll down to the next age, click the drop-down menu next to the Name Servers option, and select Google Name Servers.
- Now, link to a WiFi network and verify whether or not the DHCP error has been fixed. If it doesn’t, then restart your computer and go to the network setup page that displays the mistake. Next to the Name Servers label, scroll down and press the drop-down menu and pick Automatic Name Servers.
- Connect and recheck if the DHCP error is clear. If not, go to Network Settings and automatically turn off the Configure IP Address option.
Expanding the range of DHCP addresses and adjusting WiFi’s frequency band
It is possible that the device doesn’t support the WiFi frequency that is used by your router, then the device frequency should be matched to the router’s frequency.
- Open your Chrome browser, visit your router’s web portal, and log-in to your account.
- Head over to the Wireless Settings tab and press the band option to adjust it. If it’s 2.4GHz by default or vice versa, pick 5GHz.
- Save your setup and exit now. Restart your Device.
- Check if the DHCP lookup failed to show up again.
Changing the Frequency of the WiFi-Band
Changing your WiFi network’s band frequency can often fix failed DHCP lookup issue.
- In the Chrome window, open your router’s Web portal and go to the DHCP tab settings.
- To increase the DHCP IP Range, type the DHCP IP Range option’s second box value.
- Save your configuration, exit your browser, and then try again to connect to the network and check that the error has been fixed.
