Self Assigned IP address - NO internet - but only at home.

I have a White 2010 Macbook running Snow Leopard and I keep getting a message about a self assigned IP address and can not connect. But, I can connect to my neighbors internet with no problem.....it's only mine that does this. It was fine 2 days ago. I've tried inputting the IP address manually, I tried deleting the network, deleting the airport, and each time I reboot it gives me the same message. Not sure if the issue is my computer or the router. On my mothers computer she can connect with no problem (not a macbook). Any ideas? I search prior to posting and tried many of the recommendations with no luck.

I think the Wi-Fi chip of your router is spoiled, to check if this is true try connecting your MacBook with a ethernet cable and if you are able to surf the web then the Wifi of your router is spoiled.........

Airport self-assigned IP address, no internet

We got a new router from Verizon and my Mac will not connect. Network Status gave this message: 'Airport is connected to the network xxxxxx. Airport has a self-assigned IP address and may not be able to connect to the Internet.
How do I fix this an get connected to the internet?
Thanks in advance,
Mike from Baltimore

I have also encountered this problem and I have been researching it all over the internet all evening and trying everything I could find a suggestion for. Here's what I have: Two G4 Powerbooks, one is a 550MHz 15" Powerbook, the other is a 1.5 GHz 17" Powerbook, they are both running 10.4.11 with all the updates that Software Update has to offer, the 17" is connecting via built in Airport Extreme card, the 15" is connecting via Sonnets Aria Extreme PC card. I have AT&T DSL and I'm using the 2Wire modem/router they provided me with. Neither of the Powerbooks can connect wirelessly to the internet. Furthermore, they cannot even ping the wireless router. 4 days ago, both were connecting without any trouble (and had been able to reliably every day since the beginning of August when I hooked everything up). I have made no changes to my router's settings over the weekend. Nor had I made any changes to the Powerbooks' settings during that time. It just stopped working. If I wire one or both of them to the router with ethernet cables, connection works fine. My Desktop G4 which is normally wired into the router via ethernet, connects fine so I know my internet service is available.
So far, I've restarted both machines numerous times, restarted the router numerous times. Reset the WEP password. Changed the wireless security to WPA. Changed it back to WEP. Trashed the airport plist. deleted every wireless network entry in Keychain. Disabled DHCP and assigned IP numbers manually. Changed the wireless channel (I've tried 1, 6, and 11 with and without interference robustness).
I've been reading posts about this issue on half a dozen web forums (dating back to as early as June 2004). It appears to affect a variety of routers (2Wire, Netgear, Linksys), a variety of machines (Powerbooks, iBooks, MacBookPros, iMacs) a variety of OSes (10.3, 10.4, 10.5).
This thing is really getting me down. Anybody have any other ideas?

MBP Self Assigning IP Address on one router only

This seems to be a common problem and seems to have been occuring for quite some time now. I am very disappointed that Apple have not come up with a simple fix for it.
Here is my version of events: I recently upgraded to OS X Mavericks and ever since I did that my MBP will not connect to one of the routers in my office - all my other devices and all the other MBPs manage fine. I have tried the following:
- Resetting the router
- Deleting the network from Keychain Access
- Resetting the firewall
- Restarting / rebooting my MBP
- and varying combinations of the above
I fail to believe that a permanent fix has been discovered, sometimes one of the above 'fixes' will work temporarily, other times not at all. Sometimes I am able to connect to the wifi for a full day, other times for 5 minutes. Nothing should be this sporadic.
I am also disappointed that I have to trawl through forums to find answers.
Stop making me sad Apple.

If your computer connects fine to other networks/routers then it would seem logical that there is a router issue with the router that can not be connected to. Why would you assume it is an Apple problem? Make sure the router has its most current firmware and that all settings are correct. Do any other devices have issues connecting to the suspect router?

Self-assigned ip address starting with 169

Trying to connect to free wifi in paris but my gf's computer won't connect, instead it gives me a self-assigned IP address starting with 169, any thoughts on how I fix this?
Free wifi is a very big network in Paris, you only need a username and a password to sign in and can get connection almost everywhere in the city.
It works on my computer, but not on my gf's. It also works on my iphone, it's only her computer that doesn't connect. It worked on her computer aswell until yesterday evening.

Self-assigned IP Addresses 169.254.xxx.yyy are the ones your computer gives itself so that it has a name while it broadcasts a request for a better IP address. A self-assigned IP address usually persists for only a second until your Router responds with a good address. Finding yourself still stuck with a self-assigned address means you cannot reach the Router.
You should look for really fundamental problems. Is the connection method you prefer the top one in the System Preferences > Networks box? Are you too far away for a good connection? If all seems OK, use the ( Assist Me ) button in that panel and follow the Setup Assistent [not the Network diagnostics] branch to establish a good connection.

Wifi works for everyone but me - I get a "self-assigned IP address" and no Internet connection

I have the most confounding Wifi problem. I just got Verizon Fios, and it works perfectly on my roommate's laptop, his iPad, and on my iPhone. But it doesn't work on my Macbook Pro (running Lion). My Macbook has no problem connecting to other Wifi signals - in fact, there's another connection in my building that I can connect to just fine from my room.
When I try connecting to our own Verizon signal though, the Macbook hunts around for a few seconds, then connects - but says there's no Internet connection. I get an ominous exclamation mark over the Wifi icon. My computer gives me a "self-assigned IP address" and says it can't connect to the Internet.
I've tried everything I can think of: Restarting the computer, turning Wifi off and on, deleting and then re-accessing the signal, turning the firewall on and off, renewing the DHCP lease, restarting the router, switching channels on the router, and more. At this point, I'm out of ideas. Any suggestions?

Please try each of the steps that follow, in order, until resolved:
STEP 1 - Create a New User Account
System Preferences > Accounts
Click "+" to add a new account.
Log off, and then, log back on with the new user account.
Try connecting to a Wi-Fi network with your Mac's AirPort.
If this resolves the problem, there may be something amiss with your current profile and will require further troubleshooting.
If this does not resolve the problem, go ahead and log back into your normal account and go on to the next step.
STEP 2 - Preferred Networks
Delete Preferred Network(s)
System Preferences > Network > Select AirPort > Advanced > AirPort tab
Under Preferred Network, use the minus button to delete the network(s) you regularly use from the list.
Delete AirPort Keychain Entries (Note: This only applies if you connect to AirPort/Time Capsule routers)
Launch the Keychain Access application located in the \Applications\Utilities folder
Click on the "Kind" filter at the top, and look for any "AirPort network password" entries, and then, delete them.
Restart, or log out, then back in.
Add Preferred Network(s)
System Preferences > Network > Select AirPort > Advanced > AirPort tab
Under Preferred Network, click on the "+" button to add any preferred network(s).
Restart, or log out, then back in.
STEP 3 - Move System Configuration Files
Note: You will have to reestablish your network connection settings.
In Finder, go to the Macintosh HD/Library/Preferences folder.
Move (not copy) the SystemConfiguration folder to the OS X desktop.
Restart your Mac. (Note: OS X will automatically rebuild this folder and the associated files contained within.)
If this doesn't resolve the issue, you can move the folder (now on the Desktop) back to its original location.

My ipad recognizes my home network but will not connect to the internet. When I click on AirPort/preferences at the top of the imac screen it says..."AirPort has a self-assigned ip address and may not connect to the internet".How can I change ip address?

My ipad recognizes my home network but will not connect to the internet. When I click on AirPort/preferences at the top of the imac screen it says..."AirPort has a self-assigned ip address and may not connect to the internet". If this is the root of the problem,how can I change ip address?
Ipad will connect no problem to other networks.

First thing you need I think is to get your iMac connected to the Internet.
Shut down your iMac and you iPad. Then power off your router. Wait 30 seconds and power up the router.
After the router indicates that it is connected to the Internet then start up your iMac and see if it connects. If the iMac connects to the Internet then your iPad should too.
If this power up sequence doesn't work you'll have to dig into the router setup to make sure it is working properly.

Airport Connects but has Self-Assigned IP address and no internet

All right Apple this is some Bull#@$% I own 3 Apple units One is a MacBook Pro, one is a Macbook and the other is a G5 Dual processor tower. The MacBook and Tower are using OS X 10.5.5 and the MacBook Pro has OS X 10.4.11. Ok here is my problem all of a sudden all 3 units that had been connecting to the same wireless router for the past year started saying (AirPort has a self-assigned IP address and may not be able to connect to the internet) Apple Care suggested replacing the router well I did that and hello I have the same message. Its connecting but not going to the internet. Under network status I have green lights for Airport and Airport settings a yellow light for network settings and red lights for ISP, Internet and Server. I have this problem with both MacBooks both at the library, my friends house and my neighbors house thats 4 different wireless networks that do the same dang thing. I need help!!

All of a sudden I started getting "Self-assigned IP address ... Can't connect to internet" message when I attempt to connect to wi-fi at home. I tried solutions posted on the net but to no avail.

It once worked when I removed it from Network preferences and attempted a relogin - but the problem resurfaced again and is not going away. I tried the "key chain access" solution - but my Wi-Fi doesn't show up in "Sytems" at all. Any help will be appreciated. It's OS 10.6.9 MacBook Air.

The wifi icon shows no connection with the network -- the "!" mark.
However the computer sees the network, i.e. when I search in Network Preferences the network is listed.
So: 1) the computer sees the network but 2) will not connect to the network. The reason given for refusal to connect is "self-assigned IP address".
Not to be repetitive but two other Mac laptops are connected to the same network and working perfectly. The network preferences, as shown in the "advanced" section, are the same for all machines, i.e. DHCP is selected and IPv6 is Automatic.

HT4628 My Mac Air OSX10.8.5 won't connect to the internet as it says it has a self assigned IP address and thus cannot connect to the internet. I can only connect to a network by manually typing in the configuration specs. Please help.

My mac air OSX10.8.5 won't connect to the internet. It says it has a 'self assigned IP address and therefore cannot connect to the internet'. Network diagnostics is unable to the solve the problem. It happened suddenly for no reason and now I cannot connect except by typing in the configuration settings manually. Please help me!

Use the Airport Utility or log into your wireless device via http and ensure the DHCP/NAT service is enabled. If accessing via HTTP, you will need to manually set an ip within your local subnet (eg: 192.168.0.x).

Can't connect to internet..self assigned ip address problem with DSL Modem

I've run into this before, without resolution, and now again on a friend's iMac. Time to ask around...
Basically, everything appears to be assigned and configured perfectly, but the network status always shows, "...you have a self assigned IP address and may not be able to connect to the internet". Sure can't connect to the net when it says that.
I've gone thru the procedure advise before that details the sequence of events needed to insure the modem resets and recognizes the Mac and it's incoming DSL (sbcglobal) signal. The order of network priority is set properly by dragging built in ethernet to the top of the list. Modem was powered down, plugged in, and then connected to the Mac, but no solution. Any ideas? thanks

This continues to be a mystery. I've had my powerbook on several networks, and connection has, most of the time, been an automatic process. Additionally, I've installed new systems for people with the same isp, and all has been well. So easy is the process, it's never been an issue. However, following explicit procedural instructions (including powering the Mac down), has proven unsuccessful on 2 different occasions.
There is little help with the isp support in India, which is where the call routes too.
The only thing I have not done is to swap out the cable at one of the locations, but the other location, which has the same issue, works fine on the iMac there. Only when I connect my Powerbook to the modem, does the "...self assigned ip address...not be able to connect to the internet" appear.
I just keep thinking there has got to be a small detail that is being overlooked.

Airport: Self-assigned ip address, can't connect (public routers only)

this has been talkeda bout before, but is extremely frustrating, because i don't have the problem with a PC.
1/2 of the public routers i connect to have some kind of login page, most the time they just say "youre getting free internet, click here" ... but sometimes that login page never comes up, and the network card says "airport has a self-assigned ip address and may not be able to connect to the internet"
this only happens on pulic routers for me, and only ones that have login pages.
its very odd because for example, starbucks has all the same routers, all are "attwifi" now .. i go to one, i get hte login screen, go to a different one, i don't get it...and can't connect
with a PC, i get it every time.
this is undoubtably a leopard problem, that needs to be fixed. please!

Self Assigned IP address may not be able to connect to internet

I have been using my Mac laptop for several years now an connect to the internet via both the ethernet cable and wirelessly and never had any problems but today I logged on and couldnt get connected to the internet wirelessly it said Self assigned IP address may not be able to connect to the internet. I can connect via the ethernet but not wirelessly. We have two other computers in the house, one mac and one PC and they arent having any problems but my laptop is, can anyone help me, I have tried resetting PRAM if that makes sense but I can't find anything to help me or sort it out. Can anyone be of assistance, I am not technologically minded at all and usually find the mac very easy to get my head around but this has thrown me completely - if anyone can give any direction I would be greatly appreciated

You might try resetting your connection settings using the steps listed in this message:

They're not guaranteed to solve the problem, but they'll only take you a minute or so to try.

"Airport has a self assigned IP address & cannot connect to internet"

Hi, I'd appreciate any insight at all on this...
Apologies in advance for this vast post...!
(but I guess I may as well mention everything I've already tried...)
BACKGROUND:
I was recently trying to add an Airport Express Base Station to an existing ethernet and wireless network, which has been working flawlessly for 3 years.
(Network consists of an ethernet-connected G4 Dual 1.42 desktop running OS X.3.3, and two wireless-connected iBooks- one a 12" running OS X.3.5, the other a 14" on OS X.4.2).
For various reasons, I've now given up with the Airport Express, but ...
PROBLEM:
On the wireless 12" iBook- "Safari can't open the page "xxx" because it can't find the server "xxx"- ie, the internet connection is now wonky.(The problem is the same in Firefox, IE, and Camino too).
The fault must be with configuration on this laptop, as the other two machines on this network are still running and connecting normally with no problems at all.
What is the cause of this problem? (IP addresses? DNS server?)
WHAT I'VE TRIED SO FAR:
1. First looked at System Preferences --> Network --> Network Status, where I see this;
"Airport is connected to the network "Fritz!Box SL WLAN". Airport has a self-assigned IP address and may not be able to connect to the Internet."
Alongside it an amber button (which is usually green).
Then according to JohnHuber1's suggestion in Discussions on May 3rd 2006;
"Go to System Preferences --> Network and double click on Airport to open its preferences. Click on theTCP/IP tab and select Configure IvP4: "Using DHCP" and click on Apply Changes to save it."
I tried toggling this (it was already set this way), and then Restarted, but it hasn't helped.
I also tried clicking the 'Renew DHCP lease' button. Also hasn't helped.
2. Repaired permissions. It hasn't helped.
3. Read Apple KB article No:106798- 'Troubleshooting "Server could not be found" messages'.
From this article, it seems that
a) The problem cannot be caused by "an actual loss of internet connection", as the other 2 machines are still connecting fine.
b) Typing http://17.254.0.91 instead of http://www.apple.com makes no difference, therefore it doesn't APPEAR to be a DNS server problem. (?)
4. Tried to reconfigure the Airport settings using Network SetUp Assistant.
This allows me to select Airport as my connection method, select the network from the list; but once I've entered the network password and pressed 'continue', it then gives me a dialogue box, saying
"Unable to establish a network connection. Your computer could not connect to the internet. Click OK to go back and change your network settings and try again".
Returning to Network Prefs, I now see a box saying "Your Network Settings have been changed by another application".
I can't seem to get out of that vicious circle.
5. Opened a fresh Test Account, behaviour is the same here as in the regular user account.
6. Opened Network Utility, tried to 'Ping' on 17.254.0.91 (Apple site). Then tried to Ping my network router (192.168.178.1), and then also the other 2 computers on the network. Result in each case was "10 packets transmitted, 0 packets received, 100% packet loss".
What can I do to fix this problem? I suspect it's some small configuration checkbox in Network preferences which I've inadvertently altered.
But have I got any idea what I've done...?
Sorry for the epic post. But you get the idea...!
Thanks for your thoughts...
G4 Dual 1.42, FW800, 2GB RAM, (OSX.3.3), iBook G4 (1.2ghz, 1GB RAM, OSX.3.5) Mac OS X (10.3.3) 3 int.HDs, 3 Lacie ext.HDs, Logic Pro 6.4, RME Fireface 800.

Hi Grant, thanks for jumping in...
Have you removed the troublesome Airport Express?
Certainly have, that was Step 1 several days ago!
Are you using encryption?
Yes, I have to enter a password every time I've tried to use Network Set Up Assistant. I'm pretty sure I've got it right- it won't accept anything else.
Have you limited your network to only certain M.A.C. Addresses?
Not as far as I'm aware. Could I have done it inadvertently?
Is the Wireless Router set to allow the connection of slower 802.11b devices like the iBook?
Guess it must be... it worked fine before, and is still ok with the other 14" iBook.
Are you connecting to a Wireless Router and not to another Macintosh computer?
Hmm... I ASSUMED I was connecting to the WLAN router. The G4 desktop has no wireless capability itself, could I still be connecting to that regardless?
Internet access has never been affected in the past by that machine being on or off...
You will not be able to get anywhere until you have an IP address in the same subnet as your Router
(generally high octets the same, last octet different). Can you think of any reason why your Router
should not give you an IP address in this range?
Err... now I'm lost, sorry! What's an octet?
I really appreciate you taking the time to help me out Grant... sorry I'm not really up to speed!
Cheers, Andy.

Unable to connect to internet as Self assigned IP address Since Aple repair

Right this is currently winding me up a treat and i am posting this via windows under bootcamp on my iMac as it is the only way i can connect to the internet.
Picked my iMac up from the Apple store in Bristol UK (i dont know if this is related or not) but the problem has only happened since the repair!
I cannot connect to the internet or any services that use internet access, and under network settings, under ethernet it says connected (light in green) but you may be unable to access internet and it is self assigning IP address. If i go into advanced and renew DHCP nothing changes, its still has an IP address beginning 16 not 192. as normal.
I have repaired permissions, reset the Pram restarted and nothing makes any difference! The router settings have not changed and are not at fault. i can access the internet from my Mac via bootcamp, or 2 other windows computers in the house and my iphone via wifi.
Note my Mac wont connect via wireless either as it also self assigns IP address.
I dont know what to try now and am getting fed up with this, as i never have problems that dont make sense with Macs i have been an avid user for 10 years, and am well clued up with them (normally).
Can anyone shed anylight? Its a 2007 2.4Ghz Intel Core2Gb Ram 320Gb HDD 265Mb Radion HD Pro. Running OS 10.5.7 (not updated to 10.5.8 as came out when it was in for repair and i havent been able to access since)
Thanks to anyone that can help!

Right i have just rebooted after reading another post and under Security>Firewall>Allow all incoming connections this seems to allow me access (well currently so anyway)
But surely this isnt right? IF i then go back to Set specific access its now ok, but i imagine it wont be if i rebooted with it like it was before.
Also i notice i now have the follwing under allow access (which werent there before it went to the Apple store for repair)
ntpd
nmblookup
krb5kdc
I dont know what they are? Could it be this?
Thanks
