How to Fix DHCP Not Working in Windows 11

If your Windows 11 device isn’t obtaining an IP address automatically through DHCP, it can disrupt your internet connection, preventing browsing, streaming, or online work. Fixing DHCP issues ensures your network settings are correctly configured, restoring stable internet access. Before starting, make sure your device is connected to your network and you have administrator privileges on your Windows 11 PC. Having a stable wired or wireless connection is essential, as some troubleshooting steps require internet access or local network access.

What You’ll Need

• Administrator access to your Windows 11 device
• Basic understanding of network settings
• Optional: another device to verify your network connection

Step-by-Step

1. Check Network Connection: Ensure your device is properly connected to your Wi-Fi or Ethernet network. Restart your router if necessary to refresh network settings.
2. Restart Your Computer: Sometimes, a simple reboot can resolve temporary glitches affecting DHCP.
3. Disable and Enable Network Adapter:
   • Right-click the Start button and select Device Manager.
   • Expand Network adapters.
   • Right-click your network adapter and choose Disable device.

   Enable device.

4. Release and Renew IP Address:
   • Press Windows key + R to open Run, type cmd, and press Enter.
   • In the Command Prompt, type ipconfig /release and press Enter.
   • Next, type ipconfig /renew and press Enter.
   • Check if your IP address has been assigned correctly by typing ipconfig and pressing Enter. Look for an IPv4 address.
5. Set Network Adapter to Obtain IP and DNS Automatically:
   • Open Settings (Windows key + I).
   • Navigate to Network & internet > Advanced network settings.
   • Select More network adapter options.
   • Right-click your network connection and choose Properties.
   • Double-click on Internet Protocol Version 4 (TCP/IPv4).
   • Select Obtain an IP address automatically and Obtain DNS server address automatically.
   • Click OK to save changes.
6. Reset TCP/IP Stack:
   • Open Command Prompt as administrator: search for cmd, right-click, and select Run as administrator.
   • Type netsh int ip reset and press Enter.
   • Restart your computer to apply the changes.
7. Update Network Drivers:
   • Open Device Manager again.
   • Right-click your network adapter, select Update driver.
   • Choose Search automatically for updated driver software.
   • Follow prompts to install any available updates, then restart your PC.
8. Disable Firewall or Antivirus Temporarily: Sometimes, security software interferes with DHCP. Disable them temporarily and check your connection.
9. Check for Windows Updates: Ensure your Windows 11 is up to date, as updates often fix network bugs. Go to Settings > Windows Update.
10. Reset Network Settings: As a last resort, reset all network configurations.
    • Go to Settings > Network & internet > Advanced network settings.
    • Select Network reset.
    • Click Reset now and restart your PC.

Common Mistakes

• Not running Command Prompt as administrator when resetting TCP/IP.
• Disabling the wrong network adapter or not enabling it back.
• Forgetting to restart the PC after making network configuration changes.
• Manually configuring static IP addresses without proper knowledge, which can conflict with DHCP.
• Ignoring driver updates, which may be causing network issues.

Tips

• Always back up your current network settings before making major changes.
• Use the Windows Network Troubleshooter by right-clicking the network icon in the taskbar and selecting Diagnose.
• Keep your network drivers updated regularly to prevent compatibility issues.
• Check your router’s DHCP settings to ensure DHCP is enabled and functioning correctly.
• If on a corporate or managed network, contact your IT department before making advanced changes.

Troubleshooting

If the above steps do not resolve your DHCP issues, consider the following troubleshooting tips:

• Verify Router DHCP Settings: Log into your router’s admin panel and ensure DHCP is enabled. Sometimes, DHCP can be disabled accidentally or due to firmware issues.
• Test with a Different Device: Connect another device to your network to see if it also experiences DHCP issues. If yes, the problem likely lies with the router or network configuration.
• Use a Static IP Temporarily: Assign a static IP address within your network range to determine if the issue is DHCP-specific or network-wide.
• Check for Interference or Hardware Faults: Faulty network cables, damaged routers, or interference can cause network issues. Replace cables and test hardware components.
• Reset Router to Factory Settings: If DHCP problems persist, resetting your router to factory defaults might resolve configuration issues.
• Consult Your ISP or Network Admin: Sometimes, ISP outages or network restrictions cause DHCP failures. Contact your provider for support.

Frequently Asked Questions

1. Why is my Windows 11 device not obtaining an IP address automatically?

This can happen due to misconfigured network settings, outdated drivers, router issues, or DHCP server problems. Following the troubleshooting steps can usually resolve it.

2. How do I know if my DHCP server is working?

You can verify if your router’s DHCP server is active by logging into your router’s admin panel and checking DHCP settings. Also, testing other devices can help determine if the issue is local or network-wide.

3. Can I fix DHCP issues without resetting my router?

Yes, often resetting your network adapter, renewing IP configuration, or updating drivers can fix DHCP problems without needing to reset the router.

4. What should I do if renewing IP address doesn’t work?

Try resetting TCP/IP stack, updating network drivers, or manually configuring IP settings. If issues persist, check your router and network hardware.

5. How often should I update my network drivers?

Update your network drivers whenever new updates are available, especially after Windows updates or if you experience network issues. Regular updates help maintain stability.

6. Is resetting network settings safe?

Yes, but it will remove all custom network configurations, including saved Wi-Fi networks and VPN settings. Back up important settings before proceeding.
