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).

  • "ethernet has a self assigned IP address and will not connect to the internet" - how do i fix this?

    A message saying "ethernet has a self assigned IP address and will not connect to the internet" comes up whenever I plug the cable in. Everyone's computers work except for mine work in the house and I have tried different cords and connecting sites.
    Please help

    Open System Preferences/Network
    Select the Location you use at home
    You may need to click the Padlock bottom left at this point if it's locked, enter the admin password to unlock
    In the left hand column drag the Ethernet connection to the top of the list and remove any you don't use
    Click the Advanced button bottom right
    Click the TCP/IP Tab
    Set Configure IPv4 to Using DHCP
    Click OK bottom right and you should see the Router IP number appear and a unique but similar one for your Mac
    Click Ok then click Apply and close the Panel

  • 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.

  • I getting airport has a self-assigned ip address and may not be able to connect to the internet

    I getting airport has a self-assigned ip address and may not be able to connect to the internet

    I have got exactly the same message after we re-configured our router. I was connecting using my iMac wirelessly before hand, but now cannot. Our other PCs can connect wirelessly to the router so it's not the router. I have also tried the firewall solution but that doesn't work either.
    I did call Apple Support who said that a full troubleshoot would cost £35 as my computer is older than 90 days (well yes it's been working fine that's why it's over 90 days old, it's only now that it isn't!). He said a trouble shoot didn't guarantee success so I declined his offer to charge me an extortionate amount of money for nothing! He did say that the router needs to be giving the Airport an IP address, but it isn't doing it now. His only suggestion was to turn off the router and turn it back on or power down the iMac. Neither of which help.
    Anyone else had any success?

  • Ethernet has a self-assigned IP address and will not be able to connect to the internet

    Ethernet has a self-assigned IP address and will not be able to connect to the internet
    The problem appears to have been a connection error as well as the system preferences which have reset with a 'valid' IP address after a system preferences 'reboot'.

    Power off your internet router. Disconnect completely from its mains power by pulling the plug out of the mains socket. Disconnect all ethernet leads and cables to the router. Wait a minute or so and then reconnect all cables and turn on the power. See if your internet starts.

  • Ethernet has a self-assigned IP address and will not be able to connect

    Other computers with same hardware and software (MacBook + 10.6) can get online using the same DHCP cable normally but mine can not. The self-assigned IP address refuses to go away no matter what I do. However, if I connect via wireless, everything is normal.
    My 10.6 was upgraded a few weeks ago based on 10.5. Things were normal and Ethernet DHCP did work. This network problem suddenly appeared when the computer was functioning completely normal under a DHCP protocol using a cable.
    Does anyone observe similar problems? Anyone has any clue about what's going on?
    Thanks much!

    try this. i had the same problem. found this on another forum:
    1. Go to Mac/Library/Preferences/SystemConfiguration
    2. Delete the following:
    a. Com.apple.airport.prefrences.plist
    b. NetworkInterfaces.plist
    c. Preferences.plist
    3.Shut down computer
    4.reset PRAM (hold commandoption+PR keys down before gray screen when booting up)

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device. 
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

  • 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. 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?

  • Connectivity Issue: "Airport has a self-assigned ip address..."

    I've been using the same wireless network via AT&T with their own wireless modem/router that they provided for the past six months. Never had an issue EVER. Now....suddenly, it says "Airport has a self-assigned ip address and may not be able to connect to the internet."
    OK. I jumped on my girlfriends IBM, it and all the other PC computers in our house work FINE. I can also directly connect to the router via an ethernet cable and connect FINE.
    So I open up the router settings in my browser and notice that the IP address the router says my computer has is 192.168.1.100. This is not the IP address my network settings displays when I get a DHCP lease. So... I select "manually" instead of "automatically via DHCP" and type in the IP address the router seems to think my computer is. Now in the "show network status window" it says that "Airport is connected to the network" but I still can't connect to the internet.
    This is driving me completely bat **** crazy. Nothing has been changed in the wireless settings on my computer, any other computer in the house, or the router itself. This seems to have happened randomly, after searching all over the internet I can't find any solution that works for me. anyone know what's up?

    As you may have gathered, this message appears when the computer has failed to obtain an IP number from the router using DHCP, so it self-assigns a fallback number which, since the router doesn't know it, prevents connection to the internet.
    The obvious first step is to turn everything off, and then boot the router and each of the computers, one at a time, so that each should get a new DHCP lease. All the IP numbers should be issued and obtained automatically.
    This thread offers some solutions, some of which have worked for some posters:

  • "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...

    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.

  • 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.

  • Cannot connect to internet as Airport "has a self assigned IP address"?

    I suddenly cannot connet to wireless internet as the Airport has a "self assigned IP address" whatever that is. I have tried removing other wireless connectons but it makes no difference. I'm trying to use the wireless connection at the hotel I'm stying in..its working fine on this computer. Any suggestions ...PLEASE?
    Thanks

    Hmmm... well, not what I was hoping to find b/c that is not really a helpful answer, l.b, but thanks for joining in on the discussion. I too just experienced the same problem. Yesterday I was connected just fine, a little slow, but connecting just the same. I was able to do my banking, browsing & what have ya. Today I get up and have no internet connection and my computer says it Airport has self-assigned an ip address and I cannot connect to the Internet. I haven't done anything different and as I can tell, they haven't done anything different either. My iMAC will not connect, but this piece of poop del mini will as will my iphone4 and all three of my kids' ipod touches. Soooo.... anyone else have a solution b/c I am totally at a loss here. I really need my iMac to connect. Got things to do that I can't do on here.

  • Wi-Fi self-assigned IP address and won't connect to internet?

    Hi guys,
    Hoping someone can figure this one out for us as we're all starting to suffer from Wi-Fi withdrawal symptoms!!!!
    We are using iMac OS X 10.7.5. We have an ethernet connection coming directly into the iMac from the vessel's server (working on a cable laying ship) and can still gain access to the internet on the desktop itself.
    Up until this afternoon everything was working as per usual (iPhones sharing internet through network created on iMac, this needed reset roughly every 15-30 minutes in order for it to allow devices to access internet). But then all of a sudden nothing can connect to the Wi-Fi network. There are very short periods (5-10 seconds every 20-30 mins) where connections are made then drops out again. Have tried several different methods (renew DHCP Lease, create new location, etc) but nothing seems to work.
    Then I noticed that our Wi-Fi had a Self-Assigned IP address (attached a screenshot below):
    If anyone has any suggestions or ideas on how to remedy this problem it would be much appreciated, cheers .

    Can your MacBook connect to any other Wi-Fi network or just not the one provided by your AirPort base station?
    Was it able to connect before or has it never been able to connect to your network?

  • MacBook has self assigned ip address and cannot connect to the internet.

    Is there an Apple recomended fix for this problem that works? I've looked on this board and have found several similar suggestions but as yet nothing that results with consistent connection every time I restart.

    Since there is no exacting way to tell what of several suggestions offered in
    these discussion boards, you may have tried, I will offer an Apple Support
    article name and web address link; it may be you have tried this:
    • Mac OS: How to release and renew a DHCP lease
    http://support.apple.com/kb/TS1920
    And you can get a similar self-assigned IP address via a wireless network
    or a wired local network - with a theoretical connection to the internet. If
    the actual connection in software is not set correctly, the default will likely
    be something very familiar since the same one appears then.
    If the Network system preference panel is set and you have chosen the
    mode of connecting to the internet or other connected network, then
    you can set the configuration of that choice in a secondary screen. In
    order to have a choice to connect via AirPort, for example, you have to
    check box the item and also drag it into a position of priority (first.) Or,
    if you have to connect via Ethernet to a cable/DSL modem (if not USB)
    you can choose to place Ethernet in a position of priority above others.
    Then, further the Network configuration's next step to set it up correctly.
    The above link does cover the basics adequately, including a reset of
    the cable or DSL modem. If there is a cable modem and also a wireless
    base station, you may also have to reset each of them in a specific way
    in order to get them to start up and work. This may be all it takes.
    Good luck & happy computing!
