Airport card in PB G4 has "self assigned IP address"

I've been using a PB G4 with my Linksys router for quite some time, and now it won't connect to the internet. I shows the signal strength, and that's it's connected to the router but no internet. I've run all the utilities, and diagnostics, but nothing has been fixed. The only thing I see is that the Airport has a "self assigned IP address and may not be able to connect to the internet." This message is in the network preferences.
I'm not sure if this is in the correct forum, but if anyone can help that would be awesome.
Thanks in advance for your help.

When I came back to it, the battery was completely dead and the clock had reset to 1969.
It sounds like you need to replace the PRAM battery on your PB. I would suggest doing so before attempting any additional troubleshooting of the AirPort Card.
Please check out the following iFixit link to see if your PB has a PRAM battery and what it would take to replace it.

Wi-Fi has self-assigned IP address 169.254.9.151 and will not be able to connect to the Internet

In trying to setup my AirPort Extreme, it connects to the Internet on ethernetcables to computer but says it is not on WI-FI. I have configured it with all that I casn think of and yet I get, "Wi-Fi has self-assigned IP address 169.254.9.151 and will not be able to connect to the Internet." Can anyone tell me what is wrong?
I did both a soft reset and a hard reset to no avail. PLEASE someone help!!
Thanks!

I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
Power-up your computer(s).
If the above steps do not solve the problem, start over with step 1 above, but then perform the next steps between steps 1 & 2. above.
Disconnect the AirPort base station from the Internet broadband modem.
While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
Continue with step 2 in the first set of steps.
In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.

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?

Ethernet has self assigned IP Address,will not connect to internet?

Ethernet has a self assigned IP Address and will not connect to the internet.
I am on - Mac os X - 10.7.5
Using a BT Broadband Router, my power mac is connected to the network via TP-Link Plug POWERLINE. This has worked great for ever!
A week ago, my web connection dropped, network settings say "Ethernet 1 is active and has a self assigned IP Address and will not connect to the internet"
This seems to be a popular thread and I have followed all the answers I can find and the problem remains.
I also run a Powerbook on the wireless internet and other appliances such as, iPads, iPhones, and the wireless is fine.
My sky box and Xbox 360 (both ethernet via TP-Link) also have NO connection.
When I turn my laptops wireless off and try the ethernet cable (tried a new one too) instead, there is the same SELF-ASSIGNED IP ADDRESS issue.
This point me to the router or TP-Link network. I have replaced the router, same errors.
On my Powermac I have -
Deleted 'system configuration from the system folder - as advised by apple.
Tried swapping from DCHP, DCHP Manual and renewing lease etc.
Could anyone help at all? I am lost now as how to solve the problems.
All my TP-Link power line extenders show the correct lights, i.e., all on and yellow.
I am not experienced in networks, this is driving me mad now!
Any help would be appreciated
Thanks

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

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!

Airport has self-assigned IP address, authentication step fails

I am a computing consultant at a Pennsylvania university and am trying to configure the airport service on a 15" MacBook Pro (pre-unibody style ~2007) running 10.6.5.
We are trying to connect to a WPA2 Enterprise wireless network that requires username and password authentication before assigning an IP address. We configure Macs all the time here and they all work very well, in fact my own personal Macs haven't ever given me trouble. But the machine I'm working on at the moment just cannot obtain a correct IP address. We know for sure this is not a network or user account credential problem. It must be on the client computer side.
I have tried removing all old user profiles and certificates from the Keychain (our network grants a certificate automatically for new connections), I deleted preference files from the /Library/Preferences/SystemConfiguration folder, I have removed the Airport service from Network Connections, rebooted the machine and performed 3 PRAM resets just for good measure, re-added the Airport service and tried a fresh configuration. I also created and entirely different user account and tried configuring. The only thing I have not tried is reinstalling the OS which I'm really trying to avoid because I'd like to learn what is actually causing this problem. None of the above attempts have been successful.
Has anyone encountered this before in an enterprise environment? Does anyone have any ideas that I should try?
Thanks in advance!

Something like one year ago or so, i had to reinstall the OS cuz i wasn't able to make the iPhone recognized over usb for the tethering conenction...
only AFTER i found out it was related to the OS booting in 64 bits, not just 32 and using the 64 capability for those programs who required it.
I had to deal with self assigned ip too, while sharing internet conenction from airport through ethernet to another mac, but i dunno if that should help you.

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

Airport does not have IP address and Self assigned IP address

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

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.

"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 has "self assigned ip", no connection to internet but network ok

This is weird... the internet connection was working OK on my G5 desktop yesterday, today it doesn't... my work computer I brought home connected fine a few days ago but now it doesn't, the MacBook Pro I am writing this question with is working fine (hope it holds on to the connection!), our 2 iPhones are connected too. In the network settings for airport it says "self assigned ip address". Thanks in advance for any tips to correct this issue. Is this a glitch in the latest system update?

I solved my problem by reinstalling 10.5.5 and not doing the updates to 10.5.7. I don't know for sure if it is the update to 10.5.7 or the airport updates that caused my problem.
I out my old drive back in my Macbook and I had wireless again. So I out my new drive in and did the reinstall and now it works. There is a conflict with either the 10.5.7 update or the Airport update.
APPLE REALLY NEES TO FIX THESE ISSUES. you can read about them all over the internet. Many have just updated to 5.7 and then they have a problem.
So archiving and reinstalling 5.5 solved my problem. My old drive has 5.6 and it works. If had a copy of 5.6 I would have used that.
I will try doing another update to 5.7 and see if it still works. If that works I will update the airport.

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.

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.
