Most of the time, WiFi works very well. It’s fast, and it’s convenient. But sometimes, you might experience some issues with connecting to your WiFi network, like your WiFi connection dropping out for no apparent reason. In this article, we’re going to talk about how to fix a common WiFi issue — one that’s related to how your Mac assigns itself an IP address.
Most wireless internet connections require a unique IP address to allow users to access their network remotely. These are typically assigned by a router or other networking equipment via DHCP, a protocol that hands out IP addresses. Some users have reported errors with their network connections when this process is interrupted. These issues are usually easy to fix, but they can cause frustration if you don’t know how.
Apple laptops are known for their reliability, but that doesn’t mean they never have any problems. From common issues like wi-fi dropping out, to more serious problems such as hard drive failure, Apple is renowned for producing solid hardware that is generally quite reliable, and doesn’t break down as much as PCs.

Frequently Asked Questions
How do I fix self-assigned IP address on Mac WIFI?
So, you’ve changed your Wi-Fi network name or password, but can’t seem to connect your MacBook to the network. You’ve tried everything, but you get the dreaded message: “This computer has a self-assigned IP address.” The good news is that this is a fixable problem. If it’s not too late, you can get your MacBook online and start browsing the Web again. When you self-assign an IP address on your Mac, it means that there is a conflict with the existing IP address on your network. This is not an issue, but it can be if you want to connect to the internet. Here are some steps you can take to fix this issue.
Why does my Mac say self-assigned IP address?
The Wi-Fi icon on your Mac displays the IP address of the computer. The IP address can be assigned by a router or DHCP server. Your Mac’s IP address is self-assigned if your Mac has not communicated with a DHCP server or used the built-in DHCP server on your router. Mac users that have enabled the “Airport” feature on their Mac have a built-in DHCP server. While the self-assigning IP address is not an error, it can be problematic if you are not using a DHCP server. If your router or network does not have a DHCP server configured, the self-assigned address can prevent you from connecting to the Internet. The self-assigned IP address might appear when you are connecting your Mac to a network. The IP address comes from a private range of IP addresses, called an RFC1918 range. These addresses are not approved for Internet use, but are often used on local area networks. Self-assigned addresses indicate the computer is set up incorrectly and needs to be reconfigured so that it will use a publicly-reserved IP address.
What is self-assigned IP address for MacBook Pro?
This is a common problem with Macbook pro users. When you connect your Macbook Pro to a Wi-fi network, the IP address gets assigned to your Macbook by the router. But there are cases when the IP address assigned to your Macbook is ‘self assigned’ and that’s not a good thing. If you are a Mac User and you have set your Mac laptop to use a specific IP address then you can change it. However, if you don’t know what is self-assigned IP address and you want to know how to change it, then you are reading the right article.
