Wi-Fi has Self-Assigned IP Address

my macbook pro cannot connect to the internet via Wi-Fi. It always say "Wi-Fi has self-assigned IP address 169.xxx.xxx.xxx and not be able to connect to Internet." or sometimes "Wi-Fi has no IP address". What can I do?

MacBook Pro, Mac OS X (10.7.1)

I had the same problem IT told me to switch my wifi incryption from WEP to WPA. Called my internet provider and had them switch it, in two seconds. Now my MBP connects just fine.

Jan 10, 2012 10:00 AM in response to OffSunset

I have the same problem. Why can my macbook and ipod get on the same network using WEP?

Jan 10, 2012 10:25 AM in response to samyuwel

Well found the answer. Under network settings in System Pref., click the "assist me" button on the bottom of the screen. It takes you through similar steps as in "Netowrk diagnostics" but this actually WORKS! I can only assume it configures it to WPA instead of WEP.

Mar 7, 2012 9:44 PM in response to samyuwel

I have the same issue. it is not the fact that you use WEP or whatever. it is something with the computer or OS. this happens to me almost everyplace i go: home, work, airport, starbucks. It always says no IP address or that i self assigned it and it can't connect.

The only fix i've found is to restart the computer. sometimes this works, sometimes it doesn't.

If you ask the question on these boards people will tell you over and over to check your router or password or change to WEP. None of those are the issue.

Apr 29, 2012 10:49 AM in response to samyuwel

I've had this issue more often lately too, maybe only on WEP, which is what most locations use. My pet solution has been to create a new Network Location, then guess the wifi network range and configure everything Manually under the Advanced options of Network Preferences. Usually the network router is at 192.168.1.1, so I set my MacBook's IP Address to something high like 192.168.1.222. Occasionally this still doesn't work because no DNS can be found. Adding a DNS entry with 192.168.1.1 (same address as the wifi router) has done the trick in most cases. If the router won't do DNS by itself, there's always Open DNS, whose IP Addresses are 208.67.222.222 and 208.67.220.220.

The most common addresses for wifi routers are 192.168.1.1, 192.168.2.1, 10.0.1.1, and 10.0.2.1.

Dec 7, 2012 12:38 AM in response to samyuwel

None of the options above have enabled my MBP to connect to the internet.

Anyone with additional ideas to try?

Apple support have been completely silent on the matter.

Dec 7, 2012 1:02 AM in response to BigPhil71

You need to start a new thread of your own and let us know exactly what you have tried.

Feb 28, 2013 11:31 PM in response to samyuwel

I've been told that when the "self-assigned IP address" message is presented, the 169. at the beginning is an indication of the problem, thought I would throw that in there incase someone could elaborate or discredit this theory...

Mar 1, 2013 8:04 AM in response to henry95

169.x.x.x address is a self-issued address by the TCP/IP stack on a client when it cannot contact a DHCP server to get one. Generally, it was designed this way so that it would help facilitate easier networking for people who don't know how to properly set up an IP network. Technicallly speaking, you could connect two Macs together with a crossover ethernet cable and wait until they both finally self-assign themselves 169.x.x.x addresses. Once this happens, IP network connectivity will allow for both Macs to talk to each other accross that single ethernet link.

When dealing with a WIFI network, an address of 169.x.x.x usually indicates one of a few things.

1) You somehow manually misconfigured the security type and password for the WIFI network you're tying to connect to.

2) The WIFI network you're on does not have a DHCP server to issue an address.

3) The WIFI network you're on has MAC (no, not the computer Mac, lol) address blocking turned on and doesn't recognize your network card's MAC as a valid client to allow connections.

The gotcha here is that 1 and 3 usually only happens on systems that aren't smart enough check and see if the WIFI connection has accepted the password and OK'd it. On some systems and with some older encryption like WEP, as long as the passcode matched the length of the password required, it would let you connect (or rather it would show you connected but with limited connectivity). This is the state that tends to trick people into thinking they have a good WIFI connection to the network, but something else is wrong, when in fact, they DO NOT have a working connection to the network even at the base security layer (before the TCP stack even begins binding). In situations like this, you must delete the WIFI network and (on a Mac), also clear out the Keychain entries for that WIFI network because that's where the security key is stored. Once this is done, you reconnect to the network and make sure that you're tying in the (usually case sensitive) password as it's given to you. If that still doesn't work, then test with another device. If that device works, then you're still making a clarical mistake on the password on your previous device or that device has other network issues. If the second device doesn't work either, then you've either been given incorrect info for the WIFI network, the WIFI network is misconfigured to not give out DHCP IPs, the WIFI network is doing MAC blocking, the WIFI network router is locked up and not allowing new client connections (power cycle it to fix this), or you're still somehow making a clarical mistake inputting the info for it. Pretty much all these will require you to probably talk to whomever manages that WIFI network if you still want to connect to it.

Apr 14, 2013 1:10 PM in response to SwankPeRFection

This worked for me, similar problem. It's most helpful to know that the "self-assigned IP" error is misleading.

Key piece of info here was suggesting a clerical mistake in entering the password. I didn't type it in, but copied and pasted - that was the cause of my problem. Typing it in carefully solved everything. Thanks!

Apr 14, 2013 1:16 PM in response to galaxyglue

You're welcome. You'd be surprised how many times people have asked me to fix their issue with not being able to connect to a WIFI network in the office or somewhere else and 99.99% of the time it's a clerical mistake when they typed their password in. People always deny that until I type it in from their info they provide and it works fine. They go "What did you do?" Nothing, I typed it in correctly... you weren't. :rolleyes:

How to Fix a 169 IP Address Error

Having trouble reaching your DCHP servers? There are ways around that

• Shoreline Community College

• The Wireless Connection
• Routers & Firewalls
• Network Hubs
• Installing & Upgrading
• Wi-Fi & Wireless

When you can't connect to the internet , and your computer seems to have an IP address that starts with 169, there's a simple explanation. This type of error happens when a Windows computer requests an IP address and doesn't receive one. To fix this sort of 169 IP address error, your computer must be able to obtain a valid IP address from your network.

Causes of 169 IP Address Error

For a computer to access the internet through a network, it needs a valid IP address. The easiest way to make sure this happens seamlessly is through the Dynamic Host Configuration Protocol (DHCP), which is a setting that allows the router to automatically assign an IP address to each device on the network.

When a Windows computer isn't able to communicate with the DHCP server, something called Automatic Private IP Addressing (APIPA) kicks in. It assigns the computer an IP address that starts with 169.254. These IP addresses are only useful on local networks, not the internet.

Without communication between the computer and the DHCP server, and as long as the computer has a 169 IP address, it can't connect to the internet. That's why the fix for this problem involves making sure your computer and the DHCP server can communicate. When that happens, the problem basically fixes itself.

To fix an error where your computer has an invalid IP address that starts with 169, you need to make it so that the networking device in your computer is able to communicate with your network hardware .

Depending on the reason you experience this error, you may be able to accomplish this by resetting the network hardware, telling the networking device in the computer to request a new IP address, or changing some settings in the router .

Power cycle the network hardware . Turn off and unplug your modem and router, and then plug both devices back in. When the network hardware starts back up, and your computer attempts to reconnect to the network, it may be able to obtain a valid IP address.

Use the Windows networking troubleshooter . This automated process takes care of most networking problems, including ones that prevent a computer from obtaining a valid IP address.

Request a new IP address . This is a little more complicated because you need to open a command prompt and enter a series of commands. In most cases, this allows the computer to obtain a valid IP address.

Check the DHCP settings in the router . There are two ways that a router can assign IP addresses. Either the router dynamically assigns a unique IP address to each device, with no input from you, or you must assign a unique static IP address to each device manually.

DHCP is the setting that allows a router to assign IP addresses dynamically. If this setting is turned off, and you haven't set a static IP address for the computer, you won't be able to access the internet.

Disable the router . In some cases, you can fix this type of problem by disabling the networking device and then re-enabling it, or by uninstalling and reinstalling the driver. These are similar processes that both require you to access the Windows Device Manager .

An IP address , short for Internet Protocol address, is an identifying number for network hardware connected to a network. Having an IP address allows a device to communicate with other devices over an IP-based network like the internet.

DHCP using automatic IP address assignment means the same device may have different addresses over time, and there are some reasons you might not want this. To disable DHCP on a Windows computer, press the  Windows + x  keys and click  Settings > Network & Internet > Select a connection > Properties > Edit  to access DHCP settings.

A static IP address is an IP address that is manually configured for a device instead of one that is assigned by a DHCP server. It's called static since it doesn't change, unlike a a dynamic IP address that does change.

How to fix “self-assigned IP address” issue on Mac

Is your MacBook struggling to access the internet, though your Wi-Fi or Ethernet works fine? This can be due to the self-assigned IP error on your Mac. Worry not! In this guide, I’ll share how to fix the internet not working due to a self-assigned IP address error on your Mac to regain a stable network connection. 

But before we jump into the troubleshooting steps to resolve the issue, let’s understand what a self-assigned IP error is.

What does “self-assigned IP address” mean on Mac? 

The “self-assigned IP address” error on Mac refers to a situation where your device assigns an IP address and sets up an ad-hoc network instead of obtaining one from the network router or DHCP (Dynamic Host Configuration Protocol) server. This self-assigned IP address is not legitimate or acknowledged on the network.

That’s why your Mac cannot connect to the internet or other devices on the network, resulting in limited or no network connectivity. This issue occurs due to network configuration conflicts, DHCP server unavailability, or problems with Mac’s network or Firewall settings.

So, what to do when your Mac has a self-assigned IP address? Continue reading to get rid of the issue and restore standard network functionality on your Mac. 

• Check your connection
• Reboot your network devices
• Rejoin your Wi-Fi network
• Check your connection settings
• Reset your Network Preferences on Mac
• Renew DHCP Lease on macOS
• Create a new network location
• Reset the Firewall on your Mac
• Set Service Order from Mac’s network settings
• Change DNS Servers on macOS
• Check for conflicting IP address
• Disable VPN

1. Check your connection

Before diving into Mac-specific settings, ensure that your router is functioning correctly and located near your Mac to obtain a valid IP address. Besides, if you are using an Ethernet connection, plug in the cable snugly.  

I also check to validate that the cable has no fault and is in good condition. Moreover, If you are using an old Wi-Fi router, discard it and get a new one to obtain a smoother connection.

2. Reboot your network devices

Restarting both your modem and router can often resolve temporary network glitches. Power off the devices, unplug the cables and wait a few seconds. It will help them cool down, as excessive heat can cause malfunctions. After that, plug all cables, connect them to the power outlet, and turn them back on.   

In the meantime, restart your Mac once to iron out any bugs in macOS.   

• Click the Apple logo .

3. Rejoin your Wi-Fi network

Sometimes, simply forgetting and rejoining your Wi-Fi network can solve the self-assigned IP address error on your Mac.   

• Turn off Wi-Fi for a few seconds and toggle it on.

4. Check your connection settings

Verify that your Mac’s network settings are configured correctly. You must opt for the appropriate network settings to obtain IP addresses and DNS information automatically. 

• Go to your Wi-Fi Details .  I have shown the steps above.  
• Select TCP/IP from the left panel. 

You may also try turning off the IPv6, as some users reported it conflicted with the IP address assigning procedure.

• Click on the drop-down arrow beside Configure IPv6 . 

5. Reset your Network Preferences on Mac 

Resetting the network preferences can help eliminate IP address misconfiguration, causing the internet to not work. So, you must delete specific network connectivity-related files from your MacBook.

• Launch  Finder .

• Enter your Mac password to authenticate the deletion.
• Restart your Mac. It will automatically recreate the deleted files.
• Log in and connect to your Wi-Fi network.
• Go to the  TCP/IP  setting again and check the router files.

6. Renew DHCP Lease on macOS

This method is effective when the assigned IP address may have expired or encountered conflicts. When you renew the DHCP Lease, your Mac requests a new IP address from the DHCP server. It ensures a fresh and valid configuration and resolves connectivity issues.  

• Open the same TCP/IP tab window from Wi-Fi Details, as shown above. 

After renewing the lease, check if you can connect to your network. If that doesn’t help, try creating a New Network Location and renewing the lease.

7. Create a new network location

Creating a new network location lets your Mac start fresh with network settings and eliminate a self-assigned IP address.  

• Click the  Apple logo →  System Settings .

• Wait for a few seconds until your Mac connects to your Wi-Fi.

Repeat the steps of renewing the DHCP lease on your Mac, and then try connecting to your network.

When you try to perform configuration changes to the system, your Mac’s firewall experiences configuration issues. Let’s fix this problem by resetting the Firewall.

8. Reset the Firewall on your Mac

• In the menu bar, click  Go  → Go to   Folder .

• Restart your Mac.

After your system boots, it’ll ask you to allow access to numerous programs and services. You may choose to enable access depending upon your choice. Then, try connecting to your network and check if the self-assigned IP address error persists.

If you are unsure about deleting the Firewall files, you may temporarily disable it. Toggling off the Firewall on your Mac can help determine if it’s causing conflicts with network connectivity.

• Select  Network  from the left panel → Choose Firewall .

• Restart your Mac and turn it on again.

9. Set Service Order from Mac’s network settings 

Adjusting the service order can prioritize the network interface, ensuring your Mac connects to your preferred network. 

• Click the  Apple logo →  System Settings →  Network .

10. Change DNS Servers on macOS

Discarding existing DNS and switching to alternative DNS servers can resolve DNS-related issues that may contribute to the self-assigned IP address error.  

• Open System Settings → Wi-Fi → Click Details beside your Wi-Fi name.

• Add   these numbers: 8.8.8.8 8.8.4.4 1.1.1.1 9.9.9.9

11. Check for conflicting IP address 

Ensure that no other devices on your network use the same IP address as your Mac. Check your router’s DHCP client list and verify that all devices have unique IP addresses assigned.

12. Disable VPN 

If you have a VPN service enabled, disable it temporarily to see if it resolves the self-assigned IP address error. Open your Mac’s VPN settings and turn off the VPN connection. 

Bonus fixes 

You may need to attempt more complex fixes if the troubleshooting techniques outlined above do not fix the self-assigned IP address problem on your Mac:

• Update your Mac to the latest OS version.
• Verify your Mac is not infected with any malware or viruses. 
• Ensure your network devices are operating well and there are no hardware problems. 
• Reset NVRAM or PRAM on Mac to clear up the system settings memory. 

To use a static IP address, go to Apple logo → System Settings → Network → Wi-Fi → Details beside Wi-Fi name. Select TCP/IP → dropdown arrow next to Configure IPv4 . Choose Using DHCP with Manual Address and enter the static IP address. Click on OK to save.

Get back your smooth internet access!

Encountering a self-assigned IP address error on your Mac hampers your work, so you should address it ASAP. You can tackle the issue and restore a stable and reliable network connection using these troubleshooting techniques. If the problem isn’t resolved, contact Apple Support and seek assistance.

Currently reading My NAS went "self-assigned IP" on me. How to fix?

• 23. May 2023

My perfectly functional NAS went "self-assigned IP" on me (lost direct internet connection). I know how to assign an IP, but how to do this if I can not connect directly to the NAS using DSM? Synology Assistant doesn't see it and entering the new static IP 169.xxx address on my browser does not connect either. My connection is cable modem > primary mesh router > wifi > satellite mesh router >switch> DS923+ and Mac Studio. (all direct connections except wifi between the router and satellite router) This has been working perfectly for months. I have been having some internet connection issues lately (possibly VPN related). Normally when this happens, the NAS still keeps its 192xxx IP address and stays connected. This time the NAS went static IP and I can't recall how to fix this issue without DSM or Synology Assistant. Thanks for any help.

it looks like the wired connection to dhcp server is lost. you might try to connect it via ethernet cable to the router and see if you can connect. if not, a 3 seconds reset with paperclip will reset network settings and admin passord, picknit up with synology assistant.
