How to Fix Self Assigned IP Address Error on Mac

How to Fix Self-Assigned IP Address Error on MacHave you ever encountered a self-assigned IP address error on your Mac? This error can be frustrating and prevent you from accessing the internet, but fortunately, there are ways to fix it. In this article, we'll explain what a self-assigned IP address is, why it can be an issue, and provide troubleshooting steps to resolve the error.

Understanding the Self-Assigned IP Address Error

A self-assigned IP address error occurs when a Mac is unable to obtain an IP address from its network's DHCP server. Instead, the Mac assigns itself an IP address in the 169.254.x.x range, which prevents it from connecting to the internet.

Some common scenarios where the self-assigned IP address error may occur include:

• Moving your Mac to a new network
• Changing your network's hardware or settings
• Poor WiFi signal strength
• Network congestion

Troubleshooting Steps for Self-Assigned IP Address Error on Mac

To fix the self-assigned IP address error on your Mac, follow these troubleshooting steps:

• Step 1: Restart your Mac and your router

Sometimes, the simplest solution is the most effective. Try restarting both your Mac and your router to see if that resolves the issue.

• Step 2: Release and renew your DHCP lease

If restarting your devices doesn't work, try releasing and renewing your DHCP lease. To do this, go to System Preferences > Network > Advanced > TCP/IP. Click "Renew DHCP Lease" and wait for the process to complete.

• Step 3: Create a new network location

Creating a new network location can often resolve network-related issues. To do this, go to System Preferences > Network and click on the Location dropdown menu. Select "Edit Locations" and click the "+" button to create a new location. Name the location and click "Done". Then, try connecting to the internet again.

• Step 4: Manually configure your network settings

If the previous steps didn't work, try manually configuring your network settings. Go to System Preferences > Network > Advanced > TCP/IP and select "Configure IPv4: Manually". Enter your network's IP address, subnet mask, and router address. Click "OK" and try connecting to the internet.

• Step 5: Update your Mac's network settings

Outdated network settings can also cause the self-assigned IP address error. To update your settings, go to System Preferences > Network > Assist Me > Diagnostics. Follow the prompts to diagnose and repair any network issues.

• Step 6: Check for hardware issues

If the previous steps didn't work, there may be a hardware issue causing the error. Try connecting your Mac to a different network or using a different router to see if that resolves the issue. If not, contact Apple Support for further assistance.
