Self-assigned IP address for AirPort

If you're having this problem, go into Security and allow all incoming connections. Then turn airport off then back on. This should fix your problem. You can go back to your original setting if you choose. Let me know if this works for everyone.

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.

  • 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.

  • Solving self-assigned ip address for Mountain Lion

    Like every thread I've ran into, so far, I'm also having iissues resoloving the self-assigned ip address "nightmare" on my 2009 MBP after ugrading to Mountain Lion.  I've tried everything the threads have suggested, ranging from creating new locations to deleting network preferences.  Does ANYONE have a solution that worked?

    Do this the stuff you find at the bottom of this thread:

  • Rebuilding aMacBook 1.83 GHz Intel Core Duo, hard drive failure so rebuilding system.  Aircard will not stop self-assigning IP address.  Any ideas how to resolve successfully?

    Had hard drive failure on MacBook 1.83 GHz Intel Core Duo, so had to rebuild the OS on new drive. Was on Lion 10.7.5 prior to failure, but had to reinstall Snow Leopard 10.6.3 since that was most recent OS on media I had.  After finally getting ethernet connection to router working, was able to get to internet and download / upgrade to 10.6.8.  I assume I can probably buy the upgrade to Mountain Lion 10.8 from there.
    Problem is this, Airport will not stop self-assigning IP address for my wireless connection, and unless I can get wireless back on this laptop, doesn't make a lot of sense to continue the rebuild and reinstall of all the software that was on it prior to HD failure.  Only way to my home network and router is ethernet now.  Everything else on my network (Apple MacBook Pro laptops, iPhones, desktops, and non-Apple printers and laptops) is hooking up to router wirelessly fine.
    Any ideas how to resolve successfully so that the airport will stop self-assigning and allow the router to assign the IP address?

  • 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.

  • 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,

    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 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.

  • Airport extreme 4th generation - self-assigned IP address

    2 Airport extreme 4th generation with latest firmware. extented network in bridge mode.
    After switching providers, I reset both my airports and set them up new accordingto manual.
    Only some devices (less than 50!) at times can't get an IP address.
    Error msg: Airport has a self-assigned IP address .......... and will not be able to connect to the internet.
    My new provider told me it is an internal probem. Quote: This is an internal issue between your devices and your internal routers. we only gives an address to your router and it is your router that gives your devices an address.
    My question is, which part of the manual settings in Airport Utility affect the distribution of internal IP addresses?
    or how to change my set-up to avoid the problem I'm experiencing?
    thanks a lot.

    When in brigde mode your provider has to supply at least one IP address for each devices you want to connect.
    Alt. turn bridge mode off in Airport Utilities and let your Base station distribute IP addresses. For that you have to enter two DNS addresses.
    HTH.

  • One SOLUTION for "self assigned IP address"

    Hello there, dealing with the nasty issue of "self assigned IP address" has been my latest two days nightmare, I tried lots and lots of solutions I read in forums here and there without getting to a point.
    I started this post because I want to post here a solution that really worked for me and I haven't seen it posted over the web.
    I don't remember where but I saw the comment that WEP encryption by the router is not very mac compatible as opposed to WPA. So a while ago when I entered my router home screen (Thomson TG585 v7) I saw the option to enable WPA-PSK encryption and went for it, I can tell you it inmediatelly got me online and till now my airport wireless conection is working perfectly.
    I'm not any mac/web guru and maybe I'm stepping some technical details but I want to share this tip with all of you because I know it can be a really nasty problem that one of the gat dam "self assigned IP address" and this may help somebody else. ;-)
    Best regards

    Great tip Luis, thanks!

  • 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.

  • 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.
