Problems connecting Airport - self assigned IP addresses

Greetings,
I upgraded to a powerbook a few months back, and everything seemed to be working well enough until today. My internet connection (using airport on my powerbook) wasn't working. Usually I just unplug my modem, reconnect, and all works fine.
Today, to my horror, airport does not reconnect as usual and I see the note
AirPort has the self-assigned IP address xxx.xxx.xx.x and will not be able to connect to the Internet.
I've tried using snow leopard cache cleaner, I've tried restarting, I've turned off my iPhone, and disconnected my old mac connected by ethernet.
My iPhone works, using the same wifi, and there are other wifi users nearby.
Not sure what else to mention, any ideas?

try to do it manual:
decide a ipv4 close to your iphone (if iphone has xxx.xxx.x.7) like x.8
next, net-mask must be 255.255.255.0 (if there is something other it's wrong)
router is seen when you open network in iphone, take this.
could be like: 192.168.1.1, if your ip starts with 192 ...
all this in network/more options

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!

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.

Airport self-assigned IP address not able to connect to the internet

I installed airport into my eMac and have been using for over a month with no problems. Today I crashed using iWeb and had to restart with the startup button. Upon restart I couldn't get onto the internet via airport. The computer gets on via ethernet and my MacBook can still access the internet via airport. When I am trying to connect with airport I am told I am connected to my wireless network but the System Preferences>Network with Location set to Automatic, Shows Network Status as "Airport has a self-assigned IP address and may not be able to connect to the internet." I cannot for the life of me figure out how to make it not self-assign an IP address. I hope someone out there can.

Ouch I was hoping someone would have replied after I went to bed last night.
So I looked at some other posts and tried running applejack to no avail. I also removed the network from my prefered selection and reselected it to see if the WEP was the porblem, it wasn't. Then I switched to manual selection of IP and typed in 192.168.0.1 with subnet mask 255.255.255.0. This got rid of the self-assigned IP note but when I tried to use Safari it still said I wasn't connected to the internet. Ugh. Could removing and replacing my airport card fix this problem?

Airport - Self Assigned IP Address Problems

I moved into a new place recently and having problems with my Airport connection on my MacBook Pro. I get the error
"Airport the self-assigned IP Address 169.254.23.207 and will not be able to connect to the internet" (obviously the IP varies)
It's only happened ever since I moved into this new place. Comcast is our ISP and we're using a Netgear Router my step brother bought a while back. I logged into the Router and all settings seem to be normal as far as I can tell. It only happens if the computer goes to sleep or is shut off, any situation where Airport is disabled. I usually have to keep turning Airport On and Off until it comes back. I logged into the router, none of the settings seem wrong. The ISP setting is set to Dynamic IP. It's using WPA and doesn't seem to have a problem with the key.
Here's a screenie: http://img217.imageshack.us/img217/9797/screenshot20100924at502.jpg
What could be causing this problem. It's extremely frustrating.

Of course a search for "macbook and connection dropouts" results in numerous pleas for help. That is what you searched for. Did you expect your search to find the millions of users who are not having "macbook and dropout" issues?
FWIW there are many reasons why a wifi connection will "fail or dropout", one of which may be a hardware issue. But more likely is interference, configuration, firmware, router, setup, security, not reading the manual, etc.
What would lead you to believe "Apple technicians apparently are mystified."?
I doubt very much that Apple is involved in a conspiracy of silence "Given all the macs with this problem, why is Apple silent on a fix? Is this actually a hardware problem that would require the replacement of every motherboard in every mac notebook with a faulty broadcom wifi chipset? " But then I don't subscribe to many conspiracy theories.
There are many more Macs without the problem you and others here in this help forum describe than there are with the problem.

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?

Airport " Self Assigned Ip Address" Issue SOLVED

Hi Guys,
I finally solved my problem and i just wanted to share for those who are in the same predictament. Well, for starters i have an iMac OS X Desktop. I recently just started having problems with my airport connection. I would get the following message. " Airport has a self-assigned IP address and may not be able to connect to the internet"
Now, this post is specifically for those who have tried other solutions and had no luck such as my self. Also, for those who are trying to share connection from the ethernet to airport. I have tried the "New Location" Method, The turn airport off and on method etc
So, i had to investigate myself and i have found a quite simple solution.
1. Go To > System Preferences > Network ( You should be on the exact image above )
2.Highlight Ethernet > Copy or write down The IP Address > Press the left arrow at the top left of the page, In other words go back.
3.Now Highlight Airport such as the image above > Click On " Advanced" at the bottom right of the screen.
4. You should be at the screen SIMILIAR to the one above ( depending on your computer) > Where it states " Configure IPv4" Select " Using DHCP with manual address " from the the drop down menu.
5. Where it states " IP Address" Enter your "Ethernet" IP address that you copied in step 2.
6. Click on " Apply Now" at the bottom right of the screen > A second message should now pop up confirming whether to " Apply Now " " Don't Apply" or whatever it says on your computer, just continue on clicking "Apply Now" or " Continue" , " Okay" or whatever the exact word is on your computer.
7. Go back to the original network screen, such as the one shown in the first image. ( System Prefrences >Network) , & Airport should now say connected.
So, that's what worked for me. Hopefully it will work for you too. If you need help with anything feel free to comment and i will reply soon as possible. I know how annoying this problem was for me so i am willing to help.

I'm glad it worked for you. Okay, if I understand you correctly, You are asking what password do you need when connecting to wifi on the other device ? If so, it depends on how you have your network setup. For starters, I would need to know your network specifics before I can answer. Is it an unsecured network ? Such as, your cable provider "optimumwifi" or "xfinitywifi"? Or did you create the network yourself ? If you are connecting using the Internet your cable provider provides from the modem, you do not need a password. If it asks you for an password, try using the password you used on your cable providers website. If you are using a created network. There are a few steps to retrieve the password. Also, it depends, What type of device are you trying to connect too ?

How do I get rid of airport self-assigned IP address????

I am trying to connect to a cisco router by going wireless. It is setup as a DHCP server, however, when I use the DHCP setting under network, airport settings I can not connect to the internet and the message on the network status says the the airport has a self-assigned IP address. How do i correct this situation. I have no problems connecting with ethernet connection using DHCP server. The problem is only when I try to go wireless.

The AirPort is self-assigning itself an IP address, because it either can't "see" the DHCP server or it can't recognize it.
Which Cisco router model do you have? Is it setup for standard 802.11g or b? Are you running wireless encryption: WEP or WPA?
Double-check your AirPort settings:
To setup AirPort for High-Speed Cable Internet connectivity:
System Preferences > Network > Show > Network Port Configurations
- Verify that an AirPort option exists. If it does not, click "New" to create one. - Verify that AirPort is "On" (checked)
- Verify that AirPort is at the top of the list. If it isn't, you can drag it to the top.
Systems Preferences > Network > Show > AirPort
AirPort tab
- By default, join: Automatic
TCP/IP tab
- Configure IPv4: Using DHCP
- Configure IPv6: Automatically or Off
Proxies tab
- Configure Proxies: Manually
- Select a proxy server to configure: <All proxies should be unchecked unless you specifically require a proxy for Internet access.>
- Exclude simple hostnames (unchecked)
- Bypass proxy settings for these Hosts & Domains: <leave blank>
- Use Passive FTP Mode (PASV) (checked)

Airport self assigned ip address

My desktop is having difficulty with connectivity. If connected directly with ethernet cable from modem, no problem, but if I try to use the built-in aiport, i receive a message "a self-assigned ip address has been assigned. No network connectivity". I am beyond frustrated as this knocks out my wireless routers because I have to use the one ethernet cable I have to run directly to the desktop. Anyone with knowledge and a heart?
Aloha

Just in case you are still having the problem. From the different posts in different forums looks to me that the main reason could be related to a bug in the security configuration ... I had the problem even using no security at all.
So this is what I did: among other things I compared the keychain access file with that from another macbook that was working ok, and I noticed that although my wifi network is unprotected there was an entry for it in the keychain access list (maybe from the time that I had the network protected with the deafult config from the router). So I went to network preferences on the computer that had the problem, went to advanced and selected the name of my network (configured without security), and changed it to WAP personnal security, and entered the previous access code from my router --- the same configured in the other mac keychain file ---. This created an entry for my network in the keychain access file, just as it showed in the other macbook. I then went back to network preference and change the configuration of my network back without security. AND NOW it is working, NO MORE SELF ASSIGNED IP ADDRESS. (remember that I actually I never really changed the configuration of my wifi router to make the network secured ... actually I didn't touch it at all .... well I did before some days ago trying to follow some of the suggested solutions, doing things like power cycle, reset to factory default etc, etc, which never worked)

Airport Self-Assigned IP Address Issue

Hello. I recently started having issues with my MacBook Pro's Airport connecting to my home wi-fi. The Airport icon shows I'm fully connected to the internet, however, when I click and open up Network Settings I'm being told that my Airport is self-assigning an IP address instead of getting one from the router. My roommate also has a MacBook Pro an their computer is having no issues with connecting to our wi-fi. My iPhone 4 is also not connecting to our wi-fi. I have read that you can manually assign the IP address which is how I'm connecting to my home's wi-fi now, but I feel that there has to be another way for this issue to be resolved so I don't have to spend 5 minutes trying to find an unused IP address every time I want to connect to the internet. If this has been covered in another thread, please let me know. Thanks in advance!

Self-assigned ip address -- can't connect to Airport

I have a 2006 MacBook Pro which recently started exhibiting the exact same behaviour as reported by another poster in 2011:
For some reason the computer has started self-asigning its IP address and Network Preferences says that, because of the self-assigned IP, i cannot connect to the network.
I have two other Macs connecting to the same Air Port with no issues and I've tried to duplicate those settings on the MacBook Pro but still get the "self-assigned ip" message
Tried re-setting SMC and PRAM, no change.
The only change to my wireless setup was the change from a Verizon-owned modem to an owned Motorola unit (but the MacBook Pro connected successfully, many times, after the change).
I didn't knowingly change anything on the MacBook Pro -- from one day to the next it just stopped connecting.
I'm really at a loss to understand what's going on and, of course, not happy that the MacBook Pro can't connect to my network anymore! Help!

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.

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.

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 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.

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!!

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.

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).

This thing is really getting me down. Anybody have any other ideas?

AirPort Express won't connect because of self-assigned IP address

For years, my old AirPort Express worked just fine. Then it quit (no little lights, no action), so I bought a new one.
Now I am running into the dreaded "apple self-assigned ip address 169.254.29.74" error, which is apparently a chronic Apple thing. There's discussion all over the internet about it, and nothing seems to help.
First, the equipment:
AirPort Express
OS X 10.6.8 (Please don't tell me to upgrade because my old hardware won't support the newer OS)
Processor 2 GHz Intel Core 2 Duo. (I don't have money for a new computer and this one is working fine except for this glitch)
Memory 1 GB 667 MHz DDR2 SDRAM
Actions taken so far:
Ran the AirPort setup utility (at least ten times)
Reset the AirPort to factory specs (at least ten times)
Deleted all the old Keychain references to the old network
Deleted all the old preference files, including one for a firewall
Reset the cable modem (five or six times)
Powered down the cable modem and turned it back on (only two or three times)
Physically typed in the IP address that works for Ethernet, but got the error message that it's being used by another device (This is insane because all the other devices that could connect are physically powered down. There's only one live computer trying to connect.)
Results:
I can get a new network to show up on the AirPort icon.
The Network part of System Preferences tells me that the problem is an apple self-assigned ip address 169.254.29.74 that won't connect. ("I made this and it's useless. Aren't you proud of me?)
Questions:
The documentation says this equipment will work with Snow Leopard. Is the documentation wrong? Should I try to find a simpler wireless router that doesn't demand as much from the computer?
Perhaps the AirPort is simply broken and I should return it for a new one?
Is there some secret work-around to defeat that self-assigned IP address glitch?

I am pretty sure the Express is running in the wrong mode..
The idea to plug the computer in is to check the setup.. not to need it permanently like that.. you can use either wireless or ethernet on the new express.. the old one you could only use wireless.
Please give me a screenshot of the setup of the express.
It must be in router mode.. ie when you open the airport utility and click edit.
Then go to the network tab.. it must show DHCP and NAT.. the DHCP range does not much matter..
But I also need to see that the wan port is getting an IP correctly.
