What is a self-assigned ip address

I am unable to get a wi-fi signal when I go into system preferences/network  it says self-assigned ip ? Does any know what this is and how do I get a wifi signal.

Hold down the option key and select the Wi-Fi menu in the menu bar. What values are shown for the following?
PHY Mode
Channel
Security
RSSI

  • What doesWi-Fi has the self-assigned IP address 169.254.76.213 and will not be able to connect to the Internet

    This is what i get when i try to connect with wi fi at my local liberary: Since i updated to MOUNTAIN LION!!!
    Wi-Fi has the self-assigned IP address 169.254.76.213 and will not be able to connect to the Internet
    Although i can use Snow Leopard at the same Library via a external hard drive and when the same mbp was running Lion it also didn't have any issues connecting at the same library.
    Anyone can help out?????

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

  • "self-assigned' IP address.

    Firstly to be semantic. Part of my frustration at this problem is the fact that Apple call this a "self-assigned" IP address. In no way have I assigned this IP address myself. My Macbook Pro assigned it for me.
    I have had this problem intermittently since I bought my Macbook Pro years ago. The first time I found a solution by renewing my DHCP lease and sometimes that would work, sometimes not.
    Second fix is a reboot, third fix is to make airport inactive and then re activate it again, fourth fix is to add new location from system preferences and then start from fix number one again
    I have also tried various commands suggested for terminal and tried deleting folders that have been suggested as the cause.
    But now returning from a trip overseas I get the "self [apple] - assigned IP address" message and none of the fixes that I have wasted my time applying in the past are working.
    It's almost comical because just a week ago I was saying to somone how I was thinking of moving to PC as I had had enough of trying to fix problems with my Mac.
    Hours of trawling the internet for a simple walk through of the problem suggests anything beyond what I  have already tried. I can't believe I have put up with this issue for so many years, just accepting that it's a small problem that occaisionally interupts the massive benefits of using a Mac.
    So if anyone has a final suggestion of where to go to fix the problem [on line] I would be so releived of my frustrations. If not then I am heading out to buy a PC tomorrow and I will take great pleasure in destroying my Macbook Pro.

    I have a little Macbook that connects to my wifi connection automatically without any problems and always has.
    I have a much more expensive, much more powerful 2010 Mac Pro Quad Core which is totally incapable of jumping on to the same Wifi Connection. Even if both devices are right next to one another.
    Of course, I have the usual 'Self Assigned IP' problem, and like you, I have trawled the internet endlessly following all sorts of guides, all sorts of DHCP Renewal methods and all sorts of manual methods and all sorts of Firewall settings etc etc etc.
    In the end up, none of it ever works. Except for the very rare occasionally day I'll turn the Mac Pro on and it will have randomly decided to connect to the WIFI connection and work fine.
    I gave up trying to figure it out. I can no longer connect to the internet so my Mac Pro has to live with no important updates etc. Not very future proof at all and extremely frustrating.
    I run a busy recording studio so its solely the fault of this problem that I struggle to be as competitive as my rival studios as I can not preform the simple Audio software updates everyone else can. Brilliant.
    INFURIATING.

  • Self Assigned IP Address redux

    I am getting the "Self Assigned IP Address" in my Airport connection and I can't troubleshoot the problem.
    Here's my setup and what I have been looking to accomplish..
    I have an iMac G5 with a built-in Airport Extreme card running Leopard 10.5.3. I have created a network to provide my AppleTV and my work laptop with access to the internet. I've turned Internet sharing on, and have security set to a the WEP 128 key..
    Recently I had to exchange my AppleTV for a new one, and during the 2 weeks I was without AppleTV - something has changed (and as I think through the issue, I'm not certain about when the last time I played youtube or purchased content - maybe the new appleTV doesn't have anything to do with it, and it was a software upgrade), as I am no longer able to access YouTube content or the iTunes Music store to authorize my purchased content or to purchase new music/movies. However, I am able to watch movie trailers, and preview songs. It connects to the network fine, shows a strong signal, but something isn't quite right.
    I've performed about every known solution to the AppleTV problem, and have an open post over in the AppleTV area, but in tracking down my issue, I see that my Airport connection is showing that it has a "self-assigned IP Address" and my not be able to connect to the internet. My thoughs are that if i get the self-assigned IP address problem solved, I'll solve the ITMS/YouTube issue on the AppleTV.
    My internet connection is via Verizon DSL, with a DSL modem, connected directly to my iMac with an ethernet cable. (no external router/firewall)
    I find it interesting that I can watch trailers, preview music from ITMS with the 'Self-assigned IP' but not access ITMS for purchases, etc.
    I do not have any expertise in networking and for the most part am just following what posts I've seen out there suggest to try - trashing the com.apple.airport.pref's - restarting in 'Safe' mode, etc. Rebuilding the network connections from scratch, etc. Repairing Keychain access, disabling the built in firewall, etc. Just can't get by this issue.
    Anyone with any thoughts?

    hey guys...I found the problem...it helped me very much just try to change the wireless mode from 11bgn mixed to 11bg mixed...do this from router settings . . .I guess this will help you

  • Self assigned IP Address, wireless doesn't work

    After upgrading to Leopard I keep getting "AirPort has a self-assigned IP address and may not be able to connect to the Internet." when I try to connect to the wireless network. Thus, wifi does not work at all. I've researched it best I can and it seems to be a problem with the router assigning an IP address to the mac, but why didn't this happen in Tiger? However if I play around with it for awhile it will randomly start working, but the same method doesn't fix it everytime. It also works fine in bootcamp. If I physically plug into the router, it works fine. This problem didn't exist in Tiger at all.

    Follow-up:
    On the two laptops, I finally managed to get on line by switching to a different wireless access point, on a different modem. I surmise that the communication between the Macbook DHCP client and the modem/router's DHCP server is less than 100% effective. Looking at the modem/router, I could see that all of the Macs had active connections. But, instead of showing the names of the Macs, the page showed a star (*) for each Mac. I had to compare Mac addresses to verify the connections. The MAC address, of course, is hard-wired into the computer's network interface. It appears that either the DHCP client didn't know what question to ask when it broadcast for an IP address, or it couldn't interpret the answer. Except in the case of the iMac, which worked perfectly.
    I upgraded the MacPro last, since it is my primary machine. Same story--connection with self-assigned address, which is useless. However, this time, having nothing left to lose, I restarted the modem/router, which presumably dumped any inactive connections and issued new DHCP leases.
    However, I do have a few words for the Apple GENIUSES! The Leopard network preferences page puts me in mind of a maintenance free battery. A few of the older folks will remember when you bought a car battery that had to be filled with distilled water to reconstitute the electrolyte. Then, periodically, you check the level of the liquid in the battery, and added distilled water when required. Adding water was required on occasion because some of the water would boil off under certain conditions. Then, we got the maintenance free battery, which is virtually identical to the older battery design, except that you don't have to perform the maintenance of replenishing the water. It turns out, however, that maintenance free batteries do vent on occasion, and should have water added. But, you can't add water because the battery is sealed. So, the difference between conventional and maintenance free is not that the maintenance free battery doesn't need maintenance, it is that you can't perform the maintenance without voiding the warranty.
    The Leopard network preference page won't let you set the parameters that could restore a connection. If the DHCP client doesn't work automatically, you're stuck.

  • CAN'T CONNECT-self-assigned IP address

    I haven't been able to connect to any networks for days. I keep getting this message in my network control panel under "status":
    airport is connected to the network ABC. airport has a self-assigned IP address and may not be able to connect to the internet.
    When I start getting this message, it happens to several different networks at once and on 2 different computers. What does this message even mean? That I'm out of reach or that I'm being intentionally blocked?

    Ok, I have the fix!! After several frustrating days it finally just works.
    The process:
    Upgrade your Macs to 10.6 (Snow Leopard)
    Powercycle your modem AND time capsule / airport TWICE
    Reset your time capsule with a pin or paperclip on the back
    Follow the prompts to setup your time capsule / airport access
    -- On your Macs
    Go to System Preferences > Network > Airport > Advanced > TCP/IP
    Click "Renew DHCP Lease" then click "Ok"
    Click Apply
    Turn off Airport
    Turn Airport on
    IT WORKS!!!
    One of the magical people at tech support walked me through it earlier today. The whole process took about 1.5 hrs because Show Leopard takes about an hour to install on one machine.
    Hope this helps-

  • "Self-assigned IP address" won't connect to Internet

    I have two Macs connected to my DSL modem: a MacBook Pro (10.5.2) and a PowerBook G3 'Pismo' (10.3.9). Yesterday both were working fine, but just now when I started up the PowerBook it told me "Built-in Ethernet has a self-assigned IP address and may not be able to connect to the Internet." Indeed, though the cable is connected just like yesterday, there's no Internet (though the MBP is connected just fine).
    Anyone have any idea why this happens, and what to do about it? I've tried disconnecting/reconnecting the cable, and restarting the PowerBook, to no avail.

    Your router uses a system called DHCP to allocate an IP number to any computer connected to it. So when a computer is booted, the router recognizes its presence and allocates it a number. If the computer is running 24/7 the number's 'lease' is usually renewed every few days.
    Sometimes the process falls over and the computer fails to get an IP number from the router: when this happens it allocates itself an emergency number with the results you describe. As you found, rebooting the router usually clears the problem.
    It may be possible to reprogram the router and the computer to use a fixed IP number, it depends on the router. Very possibly this would prevent the problem occurring since both ends would 'know' what the number should be from the off.

  • 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.

  • Self Assigned IP address, can't connect

    In a few instances, I will join a network, be shown as linked to the network. Then when I look at the network status page, it reads "you are connected to the internet, however the provider has a self-assigned IP address & you may not be able to link up". Can anyone explain what to do in this situation.
    Much love & thanks,

    Is the network not working at this point? What method of IP address assignement is currently selected?

  • Self assigned IP address problem?

    There are times when my Mac Pro (Lion) won't connect to my home internet and comes up with a message about a self assigned IP address. I have no idea how to solve this.

  • Self assigned ip address-Could someone help me?

    There are two Powerbooks in my house which connects wirelessly to the internet and an airport express that joins the existing wireless connection.
    When I'am using mine, I can connect without any problem, but when my girlfriend uses her mac we both get the self-assigned ip address. The only way to connect after that is by reseting the router.
    This is what i did in both computers after I read some posts here (BUT THE PROBLEM CONTINUES) and I don't know what else to do:
    "....1. Reset Open Firmware. As you turn on the machine, press & hold CmdOption+OF until you get a screen that says "Welcome to Open Firmware". At the prompt, enter "reset-nvram" (without the quotes). Press return. Enter "reset-all". Press return and the machine will restart.
    2. Open network preferences. In airport, go to advanced. Check the box that says disconnect the wireless network when logging out. (It seems incredible that it would work, but apparently it sometimes does.)
    3. Restart in "Safe" mode (hold down "Shift" while restarting). Once in Safe mode simply restart again in regular mode. http://docs.info.apple.com/article.html?artnum=306879
    4. Go into your keychain and find the password key for your network. If you connect to a WAP it will be the name of that WAP. Then in the key click on the access control tab. It probably shows selected applications. Change this to "Allow all applications to access this item"........"
    Thanks.

    My wife's PB G4 was doing the same thing. Worked fine at the Apple Store but had issues on my all Apple network at home. After resetting the routers, recreating the network etc I finally disabled the firewall and all seems to be working.

  • Self-assigned IP address problems

    I'm having a problem with my wireless router connection (my Airport card shows the network, but the "fan" is greyed out, and if I choose the network it still doesn't connect - When I check network status I get "AirPort connected to network, but has self-assigned IP address and may not be able to connect...)
    I can temporarily fix the problem by going into System Preferences to Network to Airport to Preferred Networks to Assist Me and THEN it will go to my network and turn on the path.
    I'm running Tiger 10.4.11 on a G5 iMac with the original AirPort Extreme card, and routing through a Linksys WRT54G attached to a cable modem.
    There are a lot of networks in my area, according to my wireless "fan".
    If changing channels on my router might fix this, I'd like to give it a try, but I don't know how, AND I don't want to ruin the signal to the other computers in the house, which, by the way, work just fine when the iMac loses the signal.
    If there's another way to tell the router to ignore the self-assigned IP address, or to get the AirPort to stop providing this ...
    The problem is obviously the self-assigned IP address. The question is what is causing this?
    Is it the AirPort Extreme Card?
    Is it the Linksys Wireless router?
    How do I test to see which it is, without losing the signal from the router to the other computers in the house?
    With so many people having the same problem, there must be an answer somewhere.
    Can some kind soul please point out the correct path? My tech support (teenager) will be home from college this week, and if I can prove to him that it won't ruin everything I think he'll be up to the challenge.

    Hi,
    Thank you Linc & dwb, I've had no issues with the router in the 14 months its been installed.  But tonight I've turned off the NAS and since then no drop off for wifi/ or assigning itself an IP address. 
    I will switch on the NAS once again and see what happens, would it be best to assign a static IP to the NAS?  One thing I have found when checking the homehub connection details, the mac air connects at the 5Gz Wireless as does the Kindle, which has also suffered from losing the wifi connection, where as my macbook pro only connects at 2.4Gz and like I said has not had any issue.  Not sure if this anything to do with the problem or not? 
    All I do know is that since the NAS was introduced then the problems began, so again not sure if its the NAS impacting on the router or a router setting? 
    thanks

  • Self Assigned IP Address, wher the heck did that come from?????

    Getting flipping well annoyed with this 10.4 software release! Come on Apple say something find the fix. The problem started with 10.4.4 EVERYTHING was working fine prior to installing, Wifes imac on airport, me on my G5 chatting happily away, the reason I purchased the .mac accounts and the iSights. After 10.4.4 came the problem of the iMac getting an IP address of 10.0.1.x from the airport and no longer able to connect to the internet. So I powered off the airport and connected the ethernet from the Zoom ADSL router direct, and the iMac claims there is a "self assigned IP address" on the Ethernet, which is not true, the machine uses DHCP, rebooted so many times (Windows funnily enough never needed as many reboots as OSX Tiger! and now seems like a better choice if truth be told) and everytime this self assigned IP address appears. Now if I connect my PB to the same cable I get 10.0.0.x and no problem with the internet connection. Settings are IDENTICAL, I even cloned my PB and booted the iMac from the clone and STILL we get "Self Assigned IP Address" on the iMac!
    Does anyone have any idea how to stop the self assigned ip address problem?
    Jed "Really not very happy at all" Stone

    Powered off the Zoom DSL modem for an hour or so, and
    now it all works fine, got this Gem of info from ther
    Macosxhints website, a mighty fine site it is as
    well. Regards Kev
    Does not solve the problem for me. I'm sitting in a motel with a wireless net. I can connect to the Red Carpet network, with a strong signal, but Safari says I'm not connected to the internet. Network status gives me the same dumb "self-assigned" error. TCP/IP is set for DHCP. Since it's not my base station, I can't just go and recycle it. It did work once, but I haven't been able to reconnect. I've tweaked the connection multiple ways, rebooted multiple times, etc. etc. etc.

  • Self assigned Ip address 169.254.233.194 and will not be able to connect to the internet

    self assigned IP address  and will not be able to connect to the internet. How do I fix this?

    Sorry we have no info.. so description of the problem..
    Are you using wireless? If so on what? Do you have a TC?
    Is this a new TC and failed to setup correctly? Or you have TC or some other wireless router that has been working fine and now failed?
    Plug in by ethernet? Does it now work?
    Reboot the TC.. Does it now work?
    Reboot the whole network.. restart in order.. modem.. router.. TC.. whatever other network equipment.. clients.
    Do some clients work and others fail?
    Press and hold reset on the TC. Redo the setup.. change the TC setup to fixed channels and SMB names.
    We cannot give specific answers to such vague faults.

  • Self-assigned IP address problem - My solution

    I am new to this board and created an ID just to write this post. When I searched for this self-assigned IP problem, I found almost 1 million results on Google so obviously I am not alone.
    I have this problem off and on on the wireless network at home with a Netgear router. It has never happened at my office with a D-Link router. Never happened at Starbucks or McDonalds (yes, they all offer WiFi here). But it happened at one Pizza Hut and it also at Christchurch airport about a week ago.
    Deleting one of the plist files worked once at home many months ago but this week nothing worked. My Mac usually goes back to normal by itself after I "****" it out at other WiFi networks but not this time. As a last resort, I asked my brother (our family's I.T. guy) to change the router as I had not tried that fix. He didn't do it but a day later, he gave me to oddest solution that worked in a blink of an eye.
    The solution? Key in a wrong password!!!
    1) Go to Keychain Access, delete the keychain for the problematic network.
    2) Connect back to the network
    3) Enter a WRONG password that is similar to the right one. For example, if your password is Apple123, try APPLE123. You should still connect to the network and get a self-assigned IP.
    4) Repeat Step 1. To be safe, you might want to re-boot now. I did but probably didn't have to!
    5) Repeat Step 2
    6) Enter the right password
    I'm not all that techie so all I understood from what he said was:
    1) It's probably a non-Apple router bug
    2) It's a hex key problem. The password wasn't being encoded/decoded properly so the router wasn't assigning the computer an IP address. Wasn't even reading the password which is why I could connect with a wrong one.
    He deduced that from reading a post from a guy in Spain who thought he had carelessly entered the wrong password and was wasting the community's time with his posting. I had read that post a couple of days ago too! But obviously I thought the Spaniard had just entered the wrong password and there was no fix for me to try out. My brother is a genius!
    I guess it then makes sense why fixes like:
    1) Disabling the firewall
    2) Deleting preference lists
    3) Deleting keychains
    4) Changing the router
    5) Renewing DHCP lease
    6) Resetting the router
    ...have worked for many people and not others. None of them actually fix the cause of the problem. Having searched for 3 days, I could not find the REAL reason why this happened. Personally from all I have read, I think it must be a hex key problem with Netgear and Linksys routers. I see those 2 names mentioned a **** of a lot. Maybe it's another one of those gadgets built more for PCs that don't work perfectly with Macs all the time. We used to have an Apple Airport Extreme base station but that got fried by lightning. It was not cheap.... So technically, it really isn't Apple's problem. I think if we used an Apple router, we wouldn't have a self-assigned IP address. Maybe that's why they haven't "fixed" the problem after so many years.
    Anyway, let me know if my brother's fix worked for you.
    This is my good deed for the weekend! Goodnight....!
