Other factors like network congestion, firewall restrictions, or Wi-Fi channel conflicts can also cause this issue. In this article, we will discuss different ways to solve this error.
1. Restart Your Networking Equipment and Chrome
Turning your networking equipment and Chromebook off and on again can fix the “DHCP lookup failed” error by establishing a new connection and resolving IP address issues.
2. Change the Sleep Settings of Chromebook
Changing your Chromebook’s sleep settings stops it from disconnecting when idle, helping to avoid DHCP issues. This reduces IP conflicts and network problems after sleep, supporting a stable connection. Note: Do note that this will prevent your Chromebook from completely sleeping when you close the lid. Only the screen will turn off. This is a workaround, not a fix.
3. Reconnect to the Wi-Fi Network
Disconnecting and reconnecting to the Wi-Fi network makes the Chromebook request a new IP address from the DHCP server. This reset can fix temporary connectivity issues or conflicts that caused the DHCP lookup to fail.
4. Use Google Name Servers for the Network
Using Google’s name servers can help your Chromebook connect better by avoiding issues with your network’s settings. This change provides a faster, more stable connection, reducing “DHCP lookup failed” errors.
5. Extend the DHCP Range of Addresses of the Network
Increasing the DHCP range offers more IP addresses, helping all devices connect without running out. This reduces connectivity issues, ensuring each device gets a unique IP for a stable connection.
6. Change the Frequency Band of Your Wi-Fi Network
Changing your Wi-Fi network’s frequency band can improve connectivity on your Chromebook. The 2.4 GHz band is crowded and slower, while the 5 GHz band offers less interference and faster, more stable connections, which can help keep the network running smoothly.
7. Update Chrome OS of Your Chromebook
Sometimes, updating your Chromebook’s OS is all it takes to improve network stability, with important fixes and improvements for smoother connectivity. This simple step can resolve hidden issues and ensure a more reliable Wi-Fi experience.
8. Reset Your Router/Modem to Default Settings
This issue can be caused by wrong settings in your router or modem, stopping your Chromebook from getting an IP address. Resetting the device to default settings removes any problems, restoring stable configurations for a smoother DHCP process. You can also use the web portal of your device to perform the reset operation of your device
