Windows 11 DHCP Not Working? How to Properly Enable
- DHCP is the technology that assigns dynamic IP addresses to computers and devices.
- Dynamic IP addresses are used because they're much easier to assign, but they require a connection to a DHCP server.
- To start this process, you will need to first activate DHCP from the Control Panel, and then follow the next steps mentioned in the guide.
DHCP, or Dynamic Host Configuration Protocol, is a protocol that is used to automatically assign IP addresses to your computer. It can also be used to configure other aspects as well such as the subnet mask, default gateway, and DNS server information.
A computer or device must connect to a DHCP server to get a unique IP address and configure its other network information. The majority of the time, a network router serves as the DHCP server, but a computer can do this job as well.
It’s not just computers that use DHCP, but also switches, video game consoles, and smartphones. The process starts as the device requests an IP address from the DHCP server which then assigns an IP address so that the device can communicate with the network.
What is DHCP used for?
Internet service providers (ISP) use DHCP to provide IP addresses to their customers and there are multiple reasons for which they do this. Dynamic IP addresses are more flexible than static addresses and are easier to set up and administer.
A dynamic IP address will change after a set period, usually a few months. If static addresses were the norm, you would have to sign in every time to use a network rather than just automatically connecting.
And if they were assigned manually, ISPs would have to manually give out the address to a new device and other devices in that network must then change over to the new one.
This would make connecting a device to a router very time-consuming and having to manually change everything would increase the likelihood of errors occurring.

Some PC issues are hard to tackle, especially when it comes to missing or corrupted system files and repositories of your Windows.
Be sure to use a dedicated tool, such as Fortect, which will scan and replace your broken files with their fresh versions from its repository.
With that said, this guide will show you how to multiple ways connect to a DHCP server. The guide will also show how to disable DHCP if you wish to create a static IP address instead.
How can I connect my computer to a DHCP server?
1. Enable DHCP using the Control Panel
- Click on the magnifying glasses icon on the bottom bar to bring up the Search bar.
- In the Search bar, type in Control Panel.

- From here, you can type in your own IP address, subnet mask, and default gateway for your network.
- Below that you can connect to your preferred DNS server.
- After you’re done, click the Ok button at the bottom to save.
3. Enable via the Settings menu
- Open the Start menu by either clicking on the Microsoft logo on the bottom of the screen or hit the Windows key on your keyboard.

What if I want to use a static IP?
As the name suggests, a static IP address does not change. It consistently stays that way. Once a computer has a specific address tied to it, a DHCP server can be set up to forward inbound requests to that computer.
These types of IP addresses are useful if you host a website from home, have a file server on your network, and many other situations.
Outside of these situations, it’s recommended that you stick to a dynamic IP address and DHCP. A static IP can be difficult to use because there is a lot of upkeep that goes along with it and a lot of things could go wrong if you’re not an expert.
An IP address is something incredibly important to protect and hide. If a bad actor somehow gets access to yours, that could spell a lot of trouble for you and your devices. Using a VPN is a great way to protect your IP address while you surf the internet.
It’s also recommended that you hide your IP address while on a LAN. There are multiple ways of doing like a VPN as mentioned or you could use a proxy server instead.
