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?

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, 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, 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?

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 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" 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 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!

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.

Self Assigned IP Address with Airport Extreme

I just changed my router from an Asus to AIrport Extreme.   The Airport Extreme is connected to an ATT DSL modem. I know the modem works because I can connect to the internet when I connect it directly to my IMac. However, when I try to access the internet through the airport extreme it connects temporarily and then loses the connection. It tells me that I have a self assigned IP address and cannot connect to the network. This is the case through both Ethernet and WiFi. It is also the case when I try it with other devices (e.g. IPad, MacBook).
I know there are lots and lots of threads in this forum (and others) on this topic. I have been pouring over them for days and trying everything I could find including but not limited to--
Rebooting/power cycling
Keychain clearing and repairing
Renewing DHCP lease
Turning off firewall and virus barrier
deleting and recreating network
The modem is set up based on the ATT instructions for when it is to be connected to a non ATT router, thus it is in Bridge mode and the Airport Express is set to use PPPoE.   OS and all firmware is up to date.
There is another issue which may or may not be related. It is also an issue for which there are many existing threads (but apparently no definitive solution). My Imac keeps giving me a message that the name of my computer is already in use and has been changed to.....
http://https://discussions.apple.com/thread/4207056?start=0&tstart=0
I have tried several suggested solutions (e.g. energy savings pref, using only wifi or only ethernet to connect). So far no luck.
Both of these issues seem to have started when I switched routers.
Anyone know if the two issues are related? And whether there is a solution? Seems like both issues have been around a long time.......

Was using the wrong password option in UIXperts driver. Kept thinking it was a different protection mechanism than it was. Once the password was set, all was well. Referred back to the IOXperts installation guide (RTFM) for a clue.

Airport and a self-assigned IP address - can't access wireless net

I have a strange issue with Airport picking up a wireless network.
I'm not in my usual location using my MacBook Pro.
There is a wireless network here.
Airport sees it, and asks for the password (provided to me).
Airport looks connected, but, I see the message: "Airport has a self-assigned IP Address and may not be able to connect to the internet".
And in fact, it cannot. I've run through the diagnostics routine twice, and no go.
How do I get Airport to accept an IP address from this wireless configuration?

I am having a nearly identical problem. The solution provided did not work for me.
We have two MacBook laptops, one is mine and the other my wife's. My laptop still works fine. The AirPort communicates well with the wireless router. My wife's laptop just started having this problem about a week ago. The latest Airport software updates helped, but did not solve.
The problem is that I now have to go into network diagnostics everytime to connect my wife's laptop to the wireless router. I have to re-enter the password to the router each time. Once I enter the password, it finds the IP address and connects everything properly. I checked the keychain password and it is there, so I don't know why it keeps losing the IP address.
One thing that I did preceded this problem. I changed my router password to WEP. If anyone knows if this could cause the problem, let me know.

Why does my Airport Express say "self assigned IP address"? No IP address for the ethernet, and it is not connecting to my cable router any longer...

Why does my Airport Express say "self assigned IP address"? No IP address for the ethernet, and it is not connecting to my cable router any longer...

Some cable providers.....like mine, a well known company......seem to take anywhere from a few moments to sometimes up to 30 minutes to allow their equipment back at the cable company to fully reset and issue a new fresh connection.
So, it would not hurt to leave things powered down for 15-20 minutes or more when you perform the reset that John Galt suggests.

"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 does not have IP address and Self assigned IP address

Using a 2.66GHz Mac Pro with OS X.6.6 and a Netgear DNG200 wireless and installed Airport Extreme Card and WPA2 security.
In Network click on Airport and 'Turn on Airport' Up comes the message 'Airport dos not have IP address and is unable to connect to the internet'.
Go into advanced and double click 'Network Name'. Supply password even though remember is selected, and message changes to "Airport has Self Assigned IP address 169.254.etc.etc and will not be able to connect to the internet'.
After repeated back to Network Name and double clicking and supplying password eventually connects. Simple to reconnect by selecting Turn Airport On in Menu Bar so long as the machine is not turned off.
Any suggestions please?
