How to Fix Windows 10 Unable to Get DHCP Address Error: Step-by-Step Solutions

Encountering the “Unable to Get DHCP Address” error on Windows 10 can be frustrating. This issue prevents your computer from obtaining an IP address automatically, disrupting your internet connection.

In this article, we will guide you through simple and effective steps to resolve this error. Each step is explained clearly, so even beginners can follow along easily.

By following these solutions, you should be able to restore your network connection quickly. Let’s get started with some quick checks before diving into the fixes.

Understanding why this error occurs helps in solving it efficiently. Most often, it relates to network settings or hardware communication problems.

Quick Note: Prerequisites and Initial Checks

Before you begin troubleshooting, make sure to do the following quick checks:

  • Restart Your Router and PC: Sometimes, a simple reboot of your router and computer can fix temporary network glitches.
  • Check Physical Connections: If you’re using an Ethernet cable, ensure it’s properly plugged in and not damaged.
  • Confirm Network Availability: Make sure your internet service is active and other devices can connect to the network.
  • Disable VPN or Proxy: VPNs or proxies can interfere with DHCP communication, so turn them off temporarily.

Step 1: Restart the DHCP Client Service

The DHCP Client service in Windows handles the process of getting an IP address. Restarting this service can often fix minor issues.

  1. Press Windows + R to open the Run dialog box.
  2. Type services.msc and press Enter.
  3. In the Services window, scroll down and find DHCP Client.
  4. Right-click on DHCP Client and select Restart.
  5. Close the window and check if the error is resolved.

Why this helps: Restarting the service refreshes the DHCP process, which may have stalled or encountered an error.

Step 2: Release and Renew Your IP Address

Manually releasing and renewing your IP address forces your computer to request a new IP from the router.

  1. Press Windows + X and select Windows PowerShell (Admin) or Command Prompt (Admin).
  2. Type the following commands, pressing Enter after each one:
    3. ipconfig /release
ipconfig /renew
  3. Wait for the process to complete and then check your network connection.

Why this helps: It clears the old IP configuration and requests a fresh one, which can solve IP conflicts or lease issues.

Step 3: Reset TCP/IP Stack

The TCP/IP stack is a set of network protocols used by Windows. Resetting it restores network settings to default, fixing corrupted configurations.

  1. Open Windows PowerShell (Admin) or Command Prompt (Admin) as before.
  2. Type the following command and press Enter:
    3. netsh int ip reset
  3. Restart your computer once the command completes.

Why this helps: It clears any broken or incorrect network protocol settings that might be blocking DHCP.

Step 4: Update or Roll Back Network Adapter Drivers

Outdated or faulty drivers can cause network issues including DHCP errors.

  1. Press Windows + X and choose Device Manager.
  2. Expand Network adapters and right-click your network device.
  3. Select Update driver and choose Search automatically for updated driver software.
  4. If an update is not found or the problem started after an update, select Properties > Driver tab > Roll Back Driver.
  5. Restart your PC after updating or rolling back.

Why this helps: Incorrect drivers can prevent proper communication with your router, blocking IP assignment.

Step 5: Check Network Adapter Settings

Ensure your network adapter is set to obtain IP addresses automatically from the DHCP server.

  1. Press Windows + R, type ncpa.cpl, and press Enter.
  2. Right-click your active network connection and select Properties.
  3. Find and select Internet Protocol Version 4 (TCP/IPv4) and click Properties.
  4. Make sure both Obtain an IP address automatically and Obtain DNS server address automatically are checked.
  5. Click OK and close all windows.

Why this helps: If these settings are incorrect, your computer won’t request an IP address from the DHCP server.

Step 6: Temporarily Disable Firewall and Antivirus

Sometimes, security software blocks DHCP traffic. Disable your firewall or antivirus temporarily to check if they are causing the issue.

  • Open your antivirus or firewall program.
  • Find the option to disable protection temporarily (usually found in settings or system tray icon).
  • Turn off the protection and try connecting again.
  • If the connection works, adjust the software settings to allow DHCP or network access.

Note: Be sure to re-enable your security software after testing.

Alternative Method: Use a Static IP Address

If DHCP issues persist, setting a static IP address can be a temporary workaround.

  1. Open your network adapter’s TCP/IPv4 properties as described in Step 5.
  2. Select Use the following IP address.
  3. Enter an IP address that matches your network range (for example, if your router IP is 192.168.1.1, use 192.168.1.x where x is between 2 and 254).
  4. Enter the Subnet mask (usually 255.255.255.0) and Default gateway (your router’s IP address).
  5. Enter DNS server addresses or use public DNS like Google’s (8.8.8.8 and 8.8.4.4).
  6. Click OK to save and test your connection.

Why this helps: It bypasses the DHCP process, allowing you to connect directly with a fixed IP address.
