"Self Assigned IP Address" - connected, no internet access

I have a Netgear WGT624 v2 wireless router that is hard wired to one iMac while other laptops have wireless access to it. This set-up has been working fine for awhile - but now the laptops are saying that they are connected via the router, but they've created "self assigned IP addresses."
I called Netgear tech support and they had no answers, all they would do was make sure that the laptops were able to find the router, which they can, they just can't connect. Why are they creating their own IP addresses?
Is there a solution to this problem? What causes it?

Check your setup in the router for wireless clients. Log on to it and make sure that DHCP is enabled if you use it and you are in infrastructure mode ( wired/wireless combo ). Also, if the clients are B or G mode, make sure the router is set correctly to that mode or mixed. If the IP addresses are 169.254.xxx.xxx then they aren't really getting an address ( this may only happen in Windows, don't remember). If you don't use MAC address filtering for security, a blank list could have been turned on........ anyways, go through all your router configurations for wireless and make sure they are the same or close to the settings for the wired Mac that works. Probably just a checkmark somewhere that isn't supposed to be. Has anyone been in there messing with it? Good luck.

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.

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?

Self-Assigned IP via router - no internet access - HELP!

Hi all,
I have 10.5.7 leopard installed on my C2D Macbook.
In the past, I never had any issues connecting to wireless routers with internet connection.
As of late, I am currently getting 'Self assigned IP address' which does not allow me to connect to the internet. It is connected to the router, but just no internet access. I can see the other Shared computers (Windows PC and mate's macbook pros) but just no web access. And they do not have a problem connecting to the internet.
I have attempted the following:
1) Turned on & off Airport.
2) Deleted network connections and re-created them, rebooted in safe & PRAM modes.
3) Deleted router Key chain permissions & changed permissions to 'access all'.
4) Deleted plist files from /Library/Preferences/SystemConfiguration/
5) Off Firewall & verified against the logs to ensure it is disabled.
6) Re-installed 10.5.7 combo updates.
7) Rebooted router, changed router channel, etc. Router is on the latest Netgear firmware.
8) Assigned IP address and entered the DNS, router values manually in Leopard.
9) Clicked on renew DHCP lease several thousands to no avail..
Occasionally, DHCP will work. But once I reboot & awake the mac the internet connection drops and 'Self Assigned IP' happens.
Does anyone else have any ideas? My only conclusion is that the bug is in Leopard 10.5.7.

Make sure your router has the latest firmware. If you are out of range of the WiFI or in a marginal area, this error simply indicates that your computer is not able to access an internet router/server and simply assigns the default IP address which is of the form 169.254.xxx.xxx. Basically it's a flag that lets you know you are not connected to a DHCP server.

Airport self-assigned IP not connected to internet

Hi, Could someone please help with my problem - I have been hacking away at this for 2 nights with no success. I have 3 computers trying to connect to the internet using an Airport Extreme.
-AirPort Extreme is set up and not reporting any problems
-my MacBook Pro (10.6.6) is wirelessly connecting fine
-my MacBook (10.5.8) used to wirelessly connect fine, but since a reboot of the AirPort Extreme on the weekend it has not connected. AirPort is On with message "AirPort has a self-assigned IP address and may not be able to connect to the internet". There is an IP address of 169.254.122.47
-my G5 (10.5.?) is also showing a self-assigned IP when connecting wirelessly
I have rebooted modem and AirPort Extreme, changed passwords on the wireless network, updated AirPort Utility, connected via ethernet (works fine)
Getting desperate - any help much appreciated

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.

Self-Assigned IP error and no Internet thru cable, but fine via Airport crd

I am having a vert weird problem. Airport base station hooked to a LAN router, new Mac Pro (10.5.1) hooked via cable to Airport base station. I get the self-assigned IP address and no internet. This happens also if I hook Mac Pro directly to router via cable. Oddly enough, during all of this, my iBook connects fine to the Internet, thru the base station using its Airport card. What gives, I may throw in the towel and go out and by an Airport card for my Mac Pro to get Internet connectivity, even though it sits only 6 inches from the base station. Also not, my Power Mac G4 was hooked via cable to the Airport and worked just fine...
If someone discovers a fix, please feel free to email.
Thanks,
Bob A.

Funny you should mention that. This weekend I noticed that I can get an IP address and internet connection, either via the Ethernet cable from my AEBS or wirelessly from the AEBS on my laptop, but only one at a time and it depends which computer (iBook or Mac Pro) is on when the AEBS is toggled on/off. The only exception is my iPod touch, which can get an internet connection no matter which is the Internet connected machine(how's that for bizzare ?).
So, it appears the Linksys router that is hooked to our building's LAN is not distributing IP addresses (disconnecting the router and connecting the AEBS directly to the LAN produces the identical single IP address situation). Since using my Mac Pro with Leopard, I can only set up the AEBS in bridge mode, putting it in the DHCP mode causes the AEBS to be undetecable by the Mac Pro (haven't checked if the iBook sees it).
So I guess the questions are now:
- Shouldn't my router be assigning IP addresses from the LAN, isn't that it's job? Should I try buying a new one since I can't get AEBS to DHCP?
- Why would my iPod touch me immune from the single IP address situation?
- Any idea how to get Leopard to allow my AEBS to use DHCP?
Now I say I can't use DHCP, I mean that if I reset the AEBS, start from scratch and use assisted setup with Airport Admin Utility, and select DHCP at the place where you select Bridge or DHCP mode (or whatever the DHCP mode is called, I forget)the AEBS disappears. If I set bridge mode and then dicker around with DHCP manually, it doesn't disappear, but then it just won't give an IP address to any computer til re-rest and put back in old plain Bridge mode.
I would prefer to run the LAN right into AEBS and have it act as router and all that. I would also be fine with having a router and letting AEBS just bridge, just as long as I can connect to the Internet on more than one computer at a time.
I think I have a basic knowledge of what's going on, although my use of proper terminology is lacking, so feel free to follow up with any questions, I'd be happy to clarify.
This Leopard Mac Pro replaced a PowerMac G4 with Tiger and this all worked fine with it. When I traded computers and didn't get Internet I reset and re-setup the base station, so this might all be a Leopard problem
Of course, it brings me back to shouldn't the router hooked to my building's LAN be distributing IP addresses?
Thank you in advance for your help on this isssue.

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?

Reset your modem.

Self-assigned IP address which is not able to connect to the internet.

Okay, so my whole issue started around six or more months ago. I have a white MacBook which I have never particularly had any connectivity problems with, at least that where caused by my laptop. I constantly am on the internet at home and have never had issues with wireless connection here. I am a full time student which means I am also constantly on campus with my laptop and needing access to the internet. Even so, there I have never had any issues with connectivity.
My issue is when I go to another university campus I am unable to connect to the internet. My airport finds the network I want and connects to it but usually within a few seconds the radial bars go a light gray and have an exclamation point through them . When looking under the Airport drop down list it simply says, "Airport has a self-assigned IP address and may not be able to connect to the internet." This particular IP that is not allowing me to access the internet starts off with 169.**.*.**. I would provide the entire IP but as I am not on that campus at the moment, I can't and don't remember it fully.
I have tried SO many different things in order to find a solution but have come up empty handed every time. I've tried turning off my firewall and all of the steps that resolution includes and have also tried to resolve the issue through the creation of a new location, new network, and the use of network assistant on Airport.
I know it is not an issue of the universities wireless network because I can easily connect to the internet through my Ipod Touch without a password simply by finding the network, connecting, stating I'm a guest, and then agreeing to the terms of use. Same goes for my local campus wireless network on both my Ipod Touch and MacBook.
I am in extreme need of a resolution and would GREATLY appreciate any kind of feedback anyone can give me. If there is any other information you may need to help me out a little more accurately just let me know, I'll be happy to give you whatever I can so that I may figure this annoyance out!

By the way, totally didn't mean to categorize this under Airport for Windows. This is my first post and OBVIOUSLY a figured out a way to mess it up. My bad. :S
But again I'd appreciate any help! :]

"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.

Unable to connect to internet as Self assigned IP address Since Aple repair

Right this is currently winding me up a treat and i am posting this via windows under bootcamp on my iMac as it is the only way i can connect to the internet.
Picked my iMac up from the Apple store in Bristol UK (i dont know if this is related or not) but the problem has only happened since the repair!
I cannot connect to the internet or any services that use internet access, and under network settings, under ethernet it says connected (light in green) but you may be unable to access internet and it is self assigning IP address. If i go into advanced and renew DHCP nothing changes, its still has an IP address beginning 16 not 192. as normal.
I have repaired permissions, reset the Pram restarted and nothing makes any difference! The router settings have not changed and are not at fault. i can access the internet from my Mac via bootcamp, or 2 other windows computers in the house and my iphone via wifi.
Note my Mac wont connect via wireless either as it also self assigns IP address.
I dont know what to try now and am getting fed up with this, as i never have problems that dont make sense with Macs i have been an avid user for 10 years, and am well clued up with them (normally).
Can anyone shed anylight? Its a 2007 2.4Ghz Intel Core2Gb Ram 320Gb HDD 265Mb Radion HD Pro. Running OS 10.5.7 (not updated to 10.5.8 as came out when it was in for repair and i havent been able to access since)
Thanks to anyone that can help!

Right i have just rebooted after reading another post and under Security>Firewall>Allow all incoming connections this seems to allow me access (well currently so anyway)
But surely this isnt right? IF i then go back to Set specific access its now ok, but i imagine it wont be if i rebooted with it like it was before.
Also i notice i now have the follwing under allow access (which werent there before it went to the Apple store for repair)
ntpd
nmblookup
krb5kdc
I dont know what they are? Could it be this?
Thanks

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).

Airport self-assigned IP address not able to connect to the internet

I installed airport into my eMac and have been using for over a month with no problems. Today I crashed using iWeb and had to restart with the startup button. Upon restart I couldn't get onto the internet via airport. The computer gets on via ethernet and my MacBook can still access the internet via airport. When I am trying to connect with airport I am told I am connected to my wireless network but the System Preferences>Network with Location set to Automatic, Shows Network Status as "Airport has a self-assigned IP address and may not be able to connect to the internet." I cannot for the life of me figure out how to make it not self-assign an IP address. I hope someone out there can.

Ouch I was hoping someone would have replied after I went to bed last night.
So I looked at some other posts and tried running applejack to no avail. I also removed the network from my prefered selection and reselected it to see if the WEP was the porblem, it wasn't. Then I switched to manual selection of IP and typed in 192.168.0.1 with subnet mask 255.255.255.0. This got rid of the self-assigned IP note but when I tried to use Safari it still said I wasn't connected to the internet. Ugh. Could removing and replacing my airport card fix this problem?

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?

HT3466 Airport has self assigned IP address 169.254.153.51 and will not be able to connect to the Internet

Cannot connect to internet wirelessly because I get the message "AirPort has the self-assigned IP address 169.254.153.51 and will not be able to connect to the Internet."

I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
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.
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).
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.
