No IP assigned or self assigned IP
For over a year I have been able to connect to my Linksys WRT54G router with no problem using the Airport card in my Powerbook. I took my laptop to the families place for the holidays and connected to their wireless network. Well ever since then, I have not been able to get an IP address from my network at home. Absolutely nothing was changed on my network so I know it is a problem with my Powerbook. What can I do to make my Powerbook obtain an IP address and not self assign the generic 169.254.. IP when it does get an IP. It makes no sense that my families network would have done something to make it so I can't connect but apparently it did something to my Airport card because I can connect to the network but don't get an IP which makes it impossible to connect to the internet. Any help would be greatly appreciated. Thanks
Try the following...
Delete Preferred Network(s)
- System Preferences > Network > AirPort > Configure
- In the "By default, join:" pull-down menu, select "Preferred networks"
- Delete the network(s) you regularly use from the list
Delete AirPort Keychain Entries
- Launch the "Keychain Access" application located in Applications/Utilties.
- Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.
- Restart, or log out then back in.
Add Preferred Network(s)
- System Preferences > Network > AirPort > Configure
- In the "By default, join:" pull-down menu, select "Preferred networks"
- Add the preferred network(s) using the "+" button.
- Restart or log out then back in.

Self Assigned IP address – can't figure this out. Frustrated.
This is a long post but bear with me. It proposes a challenge for the mac connoisseur. Who knows? Might be fun?
OK, here goes:
Please help. I have been trying to fix this for about 7 months. I first noticed this issue when I started traveling around the country, from hotel to hotel. While others (PC's and Mac's) had no trouble connecting to the free wifi at these hotels, I did. I kept getting "self-assigned i.p."
This was extremely frustrating. I often had to call up the i.t. guys and ask them to help me manually put in ip address, subnet mask, router (gateway), and dns. This worked much of the time but not always.
Let me also say that, sometimes it worked perfectly! I'd say about 25% of the time (at these hotels) my internet worked perfectly – just connected immediately. The other 75... "self-assigned i.p."
I just spoke to the mac "geniuses" and they told me it's not an issue with my computer at all (either hardware or software). Are you kidding me?!?! How can they explain everyone else's internet working except mine. And I'm talking like 100 or more different hotels in a 4 month period. They were trying to tell me that it was just a coincidence every time! "You'd be surprised" one guy said. Hahaha. They said that the routers aren't accepting my computer's whatever. OK, well WHY?! The router works for everyone but me. It's something wrong with my computer right?! Well no one acknowledged this.
More background info:Just had my airport card and logic board replaced. Computer came back and the sheet said "passed all hardware tests." BUT, none of my issues (I had other ones too involving battery life and not being able to access certain websites) were fixed.
I went to an apple store. They told me to do an erase and reinstall or whatever. So I did that (by dragging and dropping everything I'd saved on an external hard drive using disk utility). By the way, I also upgraded from leopard to snow leopard. So now, if I have the same issues after this I'll know both leopard and snow leopard are screwed up.... right?
OK, so I followed their instructions on deleting and reinstalling to a tee and guess what?! Everything worked! Or so it seemed. Battery fine. Websites now accessible. I figured the airport issue was fixed too. But now that I'm not touring anymore and the airport works in my house, I never encountered any issues. Until now. At my work.
I got a new job and it's one in which I HAVE to have a computer that connects to the internet. So of course, the same issue with self assigned i.p. presents itself. Everyone else in the office has no problem. Including a Mac person that used to work there.
I've been reading some other threads that are just completely confusing me. One of them might be the solution but I thought I'd detail my troubles so that some smart computer person out there can diagnose my specific problem and give me a specific fix.
I noticed that many people believe there was a bug in one of the 10.5 updates. I am pretty quick to install updates (maybe I shouldn't be because I hear that the first updates are often buggy and maybe you should wait for a while). But this problem has continued now with Snow Leopard too so... I don't know. I don't know anything anymore. I have tried everything. And Apple is telling me it's not a problem with my computer. Give me a break.
One more interesting quirk: before doing the erase and reinstall my computer could not find the Apple Store's network. After the erase and reinstall it works. That's why I assumed everything was fine! But no. And now the Mac people are saying there's no problem because they can't see it.
BTW, I have tried all the obvious things. It's not an obvious thing. But I mean, if you think it is... then tell me I guess. But I've been in the advanced tab thousands of times. I feel like I've exhausted everything in there.
Thank you thank you thank you in advance if someone is actually able to solve my issue.continuation of console log:

Self assigned IP : still no bug fix ?
I have a problem for a long time with my Time Capsule. I use an ADSL modem and router (from Free French ADSL Provider) and my TC is plugged on it and set to "Bridge" mode.
I have many devices wired and wireless on the TC. But I have a big problem, sometimes (not all the time), my MacBook is getting a "169.254.x.x" IP address, a self assigned IP.
That's weird because sometimes it works well from 6 AM to 7 PM for example, then at 7 PM it doesn't work anymore. There is no reason why, because I haven't touch anything in my network.
It's pretty annoying. Is Apple aware of this problem ? Can we hope a fix soon ? I had many problems with the WIFI on my Mac (before, it was the "wake up" WIFI problem but it seems to be fixed in the last Lion update).
I've tried everything, reset all (TC, Macbook etc.), sometimes it works a day, the other day it's not
Thanks7pm sounds too specific to me.. get a wifi analysing software, kismet on the mac but inssider on a pc is a better utility. Locate all the wireless around you and what channels are used. I would say you are being swamped by higher intensity wireless than the TC can produce.
Go into the wireless setup and change over to manual settings.. set to N wireless.. and set to manual channels.
In 2.4ghz try 1, 6, 11.. but pick whatever is the lowest usage from your survey of wireless usage.
Also try and use 5ghz as it has less interference. When you are bridged, the IP address is derived from the modem and not the TC so the issue can be there.. try setting dhcp to fixed for the MAC address of each wireless. and set the lease to very short.. 30min or even try 10min.
There certainly are issues with Lion networking.. exactly what is hard to figure out.. but you can also try the TC with earlier firmware.. go back to 7.5.2 which was much more reliable than later ones.
You can also try it in router mode putting the modem in bridge if the ISP supports PPPoE.. or use DMZ with the modem still doing routing. The TC will kick up a double NAT error but just select to ignore it. Sometimes it will work better in router mode. -
Self-assigned or Manually Assigned IP Doesn't Work.
I've got a network of four Macs in my house, using a wireless router from Verizon. This network has been working fine for at least a year. For the last week, though, my MBP can't access the internet or see other computers. My router recognizes the MBP and the MBP shows full bars for the wireless signal, but other than that, nada. This is true whether it's a self-assigned IP or I manually create the IP (using the IP address that the router recognizes as the MBP).
The MBP hasn't left the house. The entire network set up has not changed.
I have tried:
- Manually setting the IP - worked briefly last night, but now doesn't work again.
- Resetting nvram - didn't work at all
- Power cycling computers and router in all possible permutations
- I may have tried other things that I'm not thinking of now
Any fixes or info on why this kind of thing happens would be greatly appreciated.cmoorhead wrote:

You might try resetting your connection settings using the steps listed in this message:

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 can't connect to my school's free wifi. i was able to do it before but not anymore i get the self assign ip addrees message .it has no password only a pop up window before you connect to agree to school terms for wifi use. i don't get that window anymore. i tried everything I can think of.

I need help please i have been searching all over the web for help and i see people has been having this same problem for years now.. oh yeah and i know it is not the internet cuz there are other macs connecting to it without a single problem so i think it is an isolated problem plase help....i have follow many advises such as delete the internet from your prefered netwoks. restar your commputer etc etc.
Be sure Safari does not have the Block Pop-Up Windows preference set.
Where I work now there are several unencrypted VLANs that require authentication, and Safari promptly pops up a window for me to register every time. -
DHCP & self-assigned IP problem-Airport doesn't work
I'm not really a technical type, but I'm pretty quick to pick things up and several weeks of trying to deal with this issue has made me pretty knowledgeable about things related to it specifically.
Background:
I have a month-old Macbook Pro that runs Snow Leopard and is up to date on all its software stuff. On our home network we have another pretty new Macbook Pro running 10.5.9 and a fairly old Macbook also running 10.5.9.
We have a Linksys WRT54G wireless router. Our network uses a 40-bit Hex WEP password.
Problem(s):
When I try to connect to our wireless network, Network preferences tells me that it cannot connect because of a self-assigned IP address. Sure enough, the IP address DHCP comes up with is of the 64.XX.XX.XX variety. Google's revealed that this is a common problem for all recent versions of OSX, back to at least Tiger.
The "subnet mask" it comes up with is 255.255.0.0, which is different from the settings on our other (working) computers, which is 255.255.255.0. I'm not sure what this means, or whether it's significant. Renewing the DHCP lease either comes up with the same 64.XX.XX.XX type or, sometimes, it comes up with no IP settings at all. The most frustrating thing about this is that if I chose "DHCP with manual address" and type in any in our set that I've confirmed isn't in use and hit "apply", as soon as I go back to the panel it has reverted to the 64.XX.XX.XX type.
I've also tried manually entering the router/subnet mask/IP data, as well as the DNS numbers, and that leads to the Network Settings connectivity dot thing being green, but the internet still doesn't work. In those cases, diagnostics claims that everything is fine up to and including the ISP, but that it's unable to connect to the server and internet.
Of note: some people with a similar problem have talked about networks with this problem working intermittently, but mine seems to be consistently broken.
Initially I was able to avoid fixing the problem by using our neighbors' unsecured wireless network, which is sort of awful, I know, but at least it kept me from having to deal with this for a while. Today it started to do the same thing to that network. Both networks continue to work on our Macbook and other Macbook Pro, which is why I don't think that it's a router problem.
I've been able to connect to our other computers through computer-to-computer networks—going through our main shared network (and thus the wireless router) doesn't seem to work—which I think shows that the Airport card/hardware itself is intact (?). I did try connecting to the internet through the "internet sharing" option on our Macbook, but that had the exact same problems.
Another thing that may or may not be relevant, but is equally infuriating:
I've also noticed that my Macbook Pro has more trouble staying connected to a network than our Macbook—even when it was working, it disconnected/timed out extremely often, which is something our Macbook never does, even from the same location. When I try to connect to a network it spends a very long time displaying the "searching for network" animation in the menu bar icon, sometimes after the Network Preferences pane believes that it's connected, and sometimes even after I hit the button to turn Airport off. It's also started refusing to connect to any networks at all, on occasion, which is especially evident in the process of the diagnostics box thingy, because there it actually tells me it's unable to connect rather than just playing the searching animation for ages.
Here are some other things that I've tried:
setting up a new 'location'
restarting the computer
deleting the airport preferences file
restarting in safe mode
restarting open firmware
confirming that the firewall allows all incoming thingies
resetting the router
making sure the keychain password allows all applications to access it
connecting to the internet through a computer-to-computer network from another machine
Because the situation has deteriorated over time, I'd also like to know whether people think that it's two problems (the type of router then later the airport hardware(?)/software(?) itself, perhaps) or just one. Since I've tried basically everything besides switching out our router, I'm kind of inclined to blame it on that, especially because one of the more plausible explanations for this problem that I've heard is a time-out error due to Airport expecting a faster response than it's able to get from older routers; however, the fact that other networks haven't been working means that it's not likely to be just the router. If it's just one problem, which is the simpler explanation, then I guess there's something properly wrong with my computer's software, in which case I guess I'll take it to the Apple Store. :/
I'm in love with my computer otherwise, and I'll admit that I spent a good twenty minutes sobbing out of frustration over this. Any help would be immensely appreciated.HI and Welcome to Apple Discussions...
Try Changing the Airport Channel
Open AirPort Utility, located in the Utilities folder in the Applications folder on a computer using Mac OS X.
Select the device you’re setting up, and then click Manual Setup. Enter the base station password if necessary
Click AirPort in the toolbar, and then click Wireless.
Choose a new channel from the Channel pop-up menu.

Self assigned ip and can't connect wirelessly on any apple device
Man oh man... this issue has been festering for almost an entire year now and I have not found a solution. Last August (2009) my macbook stopped wirelessly connecting to my ATT 2WIRE dsl modem saying it had a self assigned ip address. I bought the computer in July and could connect with no issues for about a month. Ever since then, I've been connected via ethernet with slow connection. At the same time, the 2 iPhones in our household also could not connect wirelessly. One G5 could connect wirelessly but was extremely weak and often dropped the signal.
I did tons of research and found zillions of other people with this issue and no resolution. I've tried every solution on macrumors, and apple discussions with no results... I've disabled firewall, renewed DHCP, tried DHCP manual (which then changes the status to say I'm connected, but nothing works in my browser), restarted, etc. At work, I can connect to our Linksys router wirelessly with no issues. When my friends come over, their macbooks and iPhones don't work either!
Originally I thought the issue was my modem so I ordered another one. Same issue. Just this week I was at my wits end and cancelled my service with ATT and switched to Clear. I acquired a Linksys router to connect to the Clear Modem and I'm STILL having this issue. The difference is now that my iPhone can connect wirelessly but my macbook still cannot. The router is a Linksys WRT51ab. My macbook pro is on version 10.5.8. I can only assume that some kind of update to airport is causing the problem. As of now, my IPv4 address is: 169.254.111.225
Please someone help me! I promise some kind of reward if you can help me fix this.Based on the model number, your Linksys router is OLD.
I'd actually suspect that your router has been the problem.
You can download the full user manual here --> http://homedownloads.cisco.com/downloads/wrt51ab_ug.pdf
I don't know if you ever secured your wireless router or renamed it from the factory defaults.
If it your Linksys wireless router is not password secured, it's possible that someone else changed settings about the time things stopped connecting.
Regardless, you can completely reset the Linksys to the factory defaults by holding down the Reset button on the Linksys for more than 10 seconds.
Do that first.
Then see if things 'magically' start connecting again. I'm guessing the phones will connect, but the Mac still won't, because of the IP address in the current configuration.
If not, here's how to configure your Mac network settings.
On your Mac, in System Preferences, Internet and Network, Network,
Click on Location, Edit Location
Click the + sign to create a new location called '_test'
(The underscore before the name will put it at the top of your Locations list where it's easy to find)
Select Ethernet (wired)
First, we'll let DHCP try to set the address.
Click Apply.
Move the selection back to Ethernet, and watch the Status.
If it shows Connected and IP address appears after a few moments, at least the WIRED configuration is working.
Now IF the Wired configuration works, lets move on to the wireless configuration...
(If the Wired configuration is still not working, post back and we'll work through it.)
Still in System Preferences, Internet and Network, Network, with the _test location you just created...
Select the AirPort interface in the left column.
Turn AirPort On.
If no Network Name appears, click on the up/down button and select Join Other Network and select your Linksys router name.
Click 'Apply'.
Leave DHCP settings alone and watch the Status to see if it connects.

Lost wireless and repeated self assigned IP address
After I updated to OSX 10.5.6 my powerbook started dropping my wireless/internet connection, and adopted a self-assigned IP address. This happened whether I connected to the router via wireless or cable.
I was eventually able to change the system configuration files as suggested in previous posts, and reset my PRMU. This has worked for a wee while, but sometimes on starting up my laptop, the machine self assigns again.
I know the internet is available as I can access it from my iphone.
Then 20min ago, whilst surfing, the internet went down AGAIN, and self-assigned its favourite IP address.
I recently updated to 10.5.7, but the problem remains.
Is this a new problem or has it been going on for a while?
Also, is it a hardware or a software problem?
Any ideas?
CharlieIf you are able to connect initially and then it drops out I would look towards possible sources of interference. While most modern devices avoid this issue fairly well, it is a possibility. Devices such as cordless phones used to cause problems.
If it is dropping out while you are physically connected, I would perhaps check the settings on your router. Most models have a reset function which will allow you to reset it to factory defaults. Then you could reconfigure it and see if the problem persists.
The other possibility is that there is a software service on your macbook that is starting up and causing the network loss. If possible, I would attempt to initialize and reinstall all the software on your macbook. Note that this will wipe everything off, so make sure you make appropriate backups before reinstalling from scratch.
Once you have reinstalled the OS, you can upgrade it to the most recent version and see if the problem persists before installing any other software that may interfere with it.
You really need to go through a process of elimination to find out whether the problem lies with the macbook or the router. However considering your iphone works fine, I would look towards the macbook first. -

MacBook Pro can't actually connect to Wi-Fi with Self-Assigned IP
Hi there
I have a 15 inch MacBook Pro and it can connect to Wi-Fi but have no actual data coming in. And it says self-assigned IP.
This only happens to my home Wi-Fi, however, I can connect and use Wi-fi at school or anywhere else perfectly. In the mean time, my Android phone and my flatmates' Windows have no problem using the Wi-Fi. The problem has been going on and off for a month, sometimes it works again and sometimes it goes wrong like this again.
During this time I mostly use my other MacBook Pro 13 inch Retina. Until today, this problem happens on my 13 Retina mac for the first time, and the 15 Pro again as well. A few days ago, my 15 Pro started working again, and today they just gone wrong together at the same time.
I just found out that my 15 pro can still work if connected to ethernet, but I can't just work in the living room, where the router is. And as you know Retina doesn't support Ethernet.
I've check on the Internet and found many people have the same problem as I do. I also tried lots of ways to fix it with the information I found online. And nothing works. I even suspect that it's actually my flatmate blocks me out with some setting on the router (Is it possible?)
Anyways, can someone please help me fix it thoroughly... Please and thanks.Each country regulates wireless networking differently. Wi-Fi devices are restricted to certain frequencies and power levels. The client devices try to find out where they are and configure themselves accordingly. Since a wireless access point (WAP) usually does not move across national boundaries, the Wi-Fi regulatory domain (country code) is set by querying the first one to respond when the client initializes itself. You don't have any direct control over it on the client. If your device is picking up the wrong country code, and is therefore locked out of using some Wi-Fi channels or operating at full power, the only lasting solution is to fix or remove the misconfigured WAP.
To find out which WAP's are broadcasting a wrong country code, do as follows.
Triple-click anywhere in the line below on this page to select it:
/S*/*/P*/*/*/*/*/airport -s | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window by pressing command-V.
The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign ($) to appear.
A TextEdit window will open with the output of the command. The first line should look like this:
SSID BSSID RSSI CHANNEL HT CC SECURITY (auth/unicast/group)
Each line below that one represents a WAP within range. Compare the two-letter code in the column headed "CC" with the ISO code for your country. The code "X0" means that the country couldn't be determined. If a WAP with a wrong code is not under your control, try restarting the computer as close as possible to your own router. -
My macbook air will not connect to the internet due to a self assigned IP address. I have tried trawling the support forums for hours, but either I can't understand the suggestions, or they don't work. Please explain to me in simplest terms how I can fix this. Many thanks!

hey, for some reason i turned on my macbook pro 2012 and it says i have no internet access. I then found out that it also says that my self assigned ip address will not connect to the internet. How is this and how can i fix it?

?? New AExtremeBS- MInis self assign an IP instead of picking up DHCP addy
Hello and help! I have a new Airport Extreme Base Station that I'm deploying in our warehouse that will host 3 minis and 3 MacBooks. It's set up to serve a DHCP range out of our LAN's subnet - .126 through .150. I'm using WPA Personal with a 13 character password. It's in "automatic" mode for channel and speed.
The clients are setup with the network in the "preferred" pane of network preferences, password added to the keychain, and set to "automatic"
The Macbooks quite happily join the network, get a dhcp addy, and surf on out to the internet and internally to other LAN computers and servers.
The minis, however, APPEAR to join up (the airport signal bars go to full power) - however, when going to browse the local net or the internet, there is no connection. Looking at the network pref pane gives the message that "airport has a self assigned IP address and may not be able to connect to the internet". No duh! When I look at the TCP/IP pane, I see that they have indeed given themselves a rendezvous addy and subnet.
Now, I assumed that - perhaps - they had timed out in trying to get the DHCP addy and had fallen back on rendevous. However, I moved the base station _directly on top_ of one of the minis, same problem.
I then set one to an addy within the DHCP range (.149), gave it the correct subnet and gateway, Locked the network pane, and still got no love.
Even stranger, after rebooting (with a locked network pane) still no love, and STRANGER still, when checking the network pane, it was unlocked. ???
The minis in question are: one core solo circa April of last year, and two new Core 2 Duos just recently purchased (this March).
I've updated ALL to the latest firmware and 10.4.9 updates that are available to this date (5/2/07). I tried to apply the .n updater to the later models, but the CD doesn't show it as available for install - and I know it's on the disk, as I've applied the update to my Mac Pro, so I'm led to believe that the Core 2 duo minis shipped with the enabler live.
I'm getting ready to punt these frickin machines. Any ideas before I put my spikes on?
Thanks all!
mini core 2 duos and a core solo Mac OS X (10.4.9)Hello,
Think I'm having the same problem. Got a iMacG5 and old PB. Both working fine till 4 days ago. I connect to a wireless network shared between 3 flats. Don't remember changing anything on settings tec.. but now the iMac looses internet connection every 10minutes or so and the PB can't connect at all. Both have full bars on the wireless signal indicator.However the PB Airport info in Network settings show's "Airport connected to 'wireless network' but has a self-assigned ISP and may not be able to connect to the internet". The iMac doesn't seem to have anything odd. The other 2 flats (with PC's) have no server problems and are working fine.
Any ideas anyone? -
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?When see the beachball cursor, note the exact time: hour, minute, second.
