'No DHCP server was found'

Hello,

I've had an issue recently pop up where my ethernet no longer works. When I go to troubleshoot is says "No DHCP server was found." I tried updating my computer and checking my network adapters for updates. I also tried the following Windows Support Q&A, but none of the suggestions worked: https://learn.microsoft.com/en-us/answers/questions/3848282/no-dhcp-server-was-found-the-dhcp-server-isnt-resp?page=1#answers

The problem: I have no internet connection over ethernet on Windows. Wifi works, every device that uses wifi works. My modem and router says they are fully functional. I have tried a reset and changing the cable, however I plan on trying both again.

Any ideas? I've never had an issue like this before and I would appreciate any insight into resolving this issue as I rely on ethernet to complete my work. Thanks!

    Hii,

    Your modem is connected to the router and, depending on your settings, there may be a conflict between them. Or it's a wired connection that's having problems and can't access DHCP. Have you tried the cable with another computer cable to see if it connects to the network?

    Do you know how to access your ISP modem or router through your browser?

    Check if you don't have any IP address set on your network adapter > Start menu > Settings > Network & Internet > Ethernet > IPv4 Address, next to it there will be an Edit option > change from manual to DHCP or Automatic.

    Give feedback if the information was useful or not.

    Thanks

    It sounds like you're experiencing a common issue with DHCP connectivity. Here are some troubleshooting steps you can take to resolve the "No DHCP server was found" error:

    1. Check the DHCP Client Service: Ensure that the DHCP Client service is running. You can check this by running the net start command in the command prompt and looking for DHCP Client.
    2. Network Adapter Settings: Verify that your network adapter is enabled and that the correct driver is installed and updated. You can do this through the Device Manager.
    3. Cables and Connections: Make sure that the Ethernet cable is securely connected and functioning. If possible, try using a different Ethernet cable or port on the router.
    4. Firewall Settings: Check if there is a firewall blocking UDP ports 67 and 68 on your computer. Ensure that these ports are open for DHCP communication.
    5. IP Configuration: You can try releasing and renewing your IP address by running the following commands in the command prompt:

    ipconfig /release ipconfig /renew

    1. Event Logs: Examine the event logs related to the DHCP Client service for any errors. You can find these logs under Applications and Services Logs in the Event Viewer.
    2. Network Trace: If the issue persists, consider using a network tracing tool like Wireshark to capture DHCP packets and analyze where the communication might be failing.

    If none of these steps resolve the issue, you may want to check if there are any static IP addresses on the network that could be conflicting with DHCP assignments or if the DHCP server itself is functioning correctly.
