Fix APIPA 169.254.x.x IP Address (DHCP Failure)

Problem overview

Your computer cannot access the network. When you check your IP address, it starts with 169.254. This indicates a failure to communicate with your router’s DHCP server, forcing the OS to assign itself a fallback address.

Common causes

• The router is frozen or its DHCP service crashed
• MAC address filtering is blocking your device on the router
• IP address pool exhaustion on the router
• Network driver or Winsock corruption

Solution 1: Restart your router

1. Unplug the power cable from your router and modem.
2. Wait 30 seconds.
3. Plug them back in and wait for the lights to indicate a stable connection.
4. Restart your computer and check if you receive a valid IP address (usually starting with 192.168 or 10.0).

Solution 2: Release and renew IP via command line

1. Open Command Prompt as administrator.
2. Run the following commands in order:

   ipconfig /release
   ipconfig /flushdns
   ipconfig /renew

3. If /renew hangs and then returns an error, your computer is physically unable to reach the router.

Solution 3: Assign a static IP as a workaround

1. Find the IP scheme of your network from another working device (e.g., if another phone has 192.168.1.15, your scheme is 192.168.1.x).
2. Press Windows Key + R, type ncpa.cpl, and press Enter.
3. Right-click your adapter -> Properties -> Internet Protocol Version 4 (TCP/IPv4) -> Properties.
4. Choose Use the following IP address.
5. Set the IP address to a high number in the subnet to avoid conflicts (e.g., 192.168.1.200).
6. Set the Subnet mask to 255.255.255.0.
7. Set the Default gateway to your router’s IP (e.g., 192.168.1.1).
8. Click OK. If internet works, the issue is strictly DHCP related on the router.

Solution 4: Disable MAC address filtering

1. Log into your router’s admin interface using a device that has a working connection.
2. Navigate to the Wireless, Security, or Access Control section.
3. Look for MAC Address Filtering or Access Control List.
4. If it is enabled, either turn it off or manually add your computer’s MAC address to the allowlist.
5. Save settings and restart the router.
