MacBook 169.254 IP address fix

I had an issue connecting to a College network using a MacBook. The Airport would recognize the Cisco Aironet, but I was only assigned a 169.254 IP address. To fix this I turned on Apple Talk.
I found the solution here:

I tried multiple solutions including "reserving" an ip address for a specific MAC address on the actual router (which is acting as the DHCP server). even this did not work.
Then I checked the "Make AppleTalk Active" and had the "Configure" option set to "Automatically". its the only thing that worked. Hope this helps.

I have the same problems with my Mac mini bought June 22. Until yesterday there is no any problems, today I found it couldn't connect Internet and the ip is 169.254.12.3, I updated DHCP, reboot, and set ip to 192.168.1.3, and so on, but all to get the same result.
At last, I tried cable to connect it, I found the ip is also 169.254.12.3, I have no way, can you help me, too?
By the way, there are 5 others device connecting to my LAN with cable or wireless, including iPad, all of them are no any problems.

Can't connect to internet, always get (169.254) ip address

Mac Mini with OS X 10.5.8
Internet connection worked for years up til now.
I know the Comcast modem is working because my other computer accesses service fine.
I only connect directly from the Comcast modem to a single computer at any one time (to prevent conflicts).
I have disconnected the battery from the Comcast modem and rebooted the modem and my computer.
I have called Comcast and had them troubleshoot the line and reset the modem. All looks fine from their end.
I have trashed all plist files that have to do with the network (and let the computer regenerate new ones). I then reconfigured the network and the settings in Network seem exactly the same.
Any ideas? Could a bad internal battery be enough to cause this? Should I zap PRAM? Any suggestions will be entertained. Thanks, Peter
(Also, in Proxies dialog, I tried removing the info (*,local, 169.254/16) in the "Bypass Proxy Settings for These Hosts and Domains" and it would cause the "Configure Proxies" selection to default to "Always Use PAC File". Had to go back and retrash all the plist files to have Proxies go back to "Configure Proxies-Manually".
Here are my settings:

In my G5 (OS X 4.11) the Network area for Proxies has "Configure Proxies" set to "Manually", same as Mac Mini (OS X 5.8); that's why I can't understand the ability of one to work and not the other. (I'm fairly clueless about all the jargon in the Network configuring process, so asking me about proxies, etc will garner few informed response.)
Yes, I did use the "Insert Image" command. Don't know why it would be messed up. I will try again here.
And I'll try powering down the Modem for a longer period. Thanks.

IPad Wi-Fi has the self-assigned IP address 169.254.210.251 and will not be able to connect to the Internet. How to fix?

Mini connects to internet via cable modem fine.
Want to have ipad connect also but mini Wi-Fi has the self-assigned IP address 169.254.210.251 and will not be able to connect to the Internet. How to fix?

Hello:
I am a long way from a wi-fi expert, but.....
You need, I think, either a router with wi-fi or an airport (express or extreme). The iPad needs to connect to to a network. In my case, I use an airport express and both my iMac and iPad 2 connect to the Internet through the airport device.

My Macbook Pro says Wi-Fi has the self-assigned IP address 169.254.74.157 and will not be able to connect to the internet.

I just got my new Macbook Pro today. When I tried to connect it to my Wi-Fi at home it won't connect. I put in my WEP key correct every time and it keeps saying "Wi-Fi has the self-assigned IP address 169.254.74.157 and will not be able to connect to the internet" . I connect my iPod touch to this same Wi-Fi all the time plus my other laptop and my phone and it works fine. Please help !! I use Verizon Fios modem/router.

Hi, it could be that the Router will not allow you onto the network..Reboot, Modem,Router & computer..
Find out the native IP address for your Router & reset the network configs''
Use Keychain Access to Delete all Internet/Router Passwords etc.. Then Roboot..

IP address 169.254....

Hello,
A few weeks ago, both my ethernet and my airport were working fine in my dormitory and anywhere I went. Then in my dormitory, the ethernet suddenly stopped working as I was using it. I didn't change any settings, I was not messing arround with anything. It just suddenly stopped! I tried asking for help to the people in the dormitory, but being in a place where no one (in the dormitories and IT technicians) really speaks my language and I don't really speak theirs, doesn't help very much. Plus the fact that they don't really seem to be able to use and fix mac problems. My ethernet cable connection works excllent with any other computer that is connected to it BUT with mine.
Anyways, everything is on automatic the way it should be, but it shows that the self assigned IP address is of 169.254. etc, and it cannot connect to the internet. It happens with both ethernet and airport. With the airport I used to connect perfectly, but now, a few places where I used to connect perfectly won't work anymore, and it shows this same IP address of 169.254.blah.blah. It has been driving me crazy not being able to connect to the internet propperly since it is the only way I can communicate with my family. Could anyone PLEASE help me? I am really desperate here T^T Thank You!!
Regards,
Omar.

Try removing all the RAM and putting in new RAM. We had a PowerMac G5 at work that couldn't connect to the Ethernet no matter what we did. I was convinced it was the motherboard/Ethernet connection failure. But after running a couple of hardware tests, it came up with bad RAM. Put in all new RAM, and lo and behold, we have Internet!!
This would explain why multiple computers can connect to an internet connection, but one computer doesn't.
I'm having this problem with my MacBook Pro right now, and will attempt to take out the RAM when I get home to see if it fixes it. I had it at work, and was in the middle of surfing on our Ethernet network, when it suddenly stopped. I just put new RAM in a few weeks ago, so one might have failed.

Why does my WRT54g sometimes give me a 169.254 address???

I have a WRT54G with firmware v1.01.0, Sep. 14, 2006. I've got an Apple G5 attached to it through one of the hardwired ethernet ports, connecting via DHCP. Once in a while, I'll get an address like 169.254.236.186 and can't connect. I have another Mac attached through a linksys wireless to ethernet bridge, and that one gets this kind of address all the time, needing to "renew DHCP lease" every couple of hours, to get a normal 192.168 address back. Can someone tell me how to fix this? Why does it give out such weird addresses? Mike Levin

When the computer fails or face the problem to get the IP from router automatically, then it will assign 169.254.x.x IP. Check the DHCP setting on wireless router and ensure you assigned big enough DHCP IP range. Also you can take a look on this wireless router configuration help..

My Airpot/Time capsule will not will not connect. It states " AirPort has the self addressed IP address 169.254.231.99 and will not connect to the internet??????l

Cant' get my AirPort to sync up with internet. I get the message "AirPort has the self addressed IP address 169.254.231.99 and will not connect to the internet. How do I fix? Thanks.

What broadband router do you have?
What model Time Capsule do you have?
If you changed the system over from another router.. have you rebooted the entire network.. particularly a cable modem.. did you power off for at least 20min..
Tell us some info and we can help.

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router (Auto is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

DHCP Address changes to 169.254.x.x after starting to download image in PE

Our network requires the user to register their computer on the network to obtain network access. This really isn't for security, but for tracking reasons. This registration is done via the web on a temporary private network they get sent to if the dhcp server doesn't recognize the machine. Once registered they can either reboot and renew their IP or just wait till the IP times out which is 2 minutes to gain access to the network with a real IP. The tempoary network runs 2 minute lease times because of the limited number of IPs and the large turnaround we have on this network during peak times. The real network runs 4 hour lease times mainly just because of the large turnaround of computers some buildings have been reduced to 1 hour because at 4 hours we would run out of IPs for the building. We have a class B subnet for real IPs that all clients get with IPv4 we have to play a delicate balancing act to keep from running out. We have in the process of implementing IPv6 which could solve some of these problems.
Back to my problem. When a bare metal computer comes in the tech needs to load the machine. At this point it is on the tempoary network. The tech boots the computer into pe either cd or pxe. Then they register the computer with configmgr and start up the correct task sequence. Even with the 2 minute lease time the client maintains constant connectivity no matter how long the user takes to register the client. You can wait days if you like. Once the task sequence is chosen and it starts to apply the image it will fail. If you push F8 and do an ipconfig it shows a 169.254.x.x ip address. If you try to renew the IP you get An error occurred while renewing interface Local Area Connection : The requested address is not valid in its context. You can release and renew and get a new IP, but at this point the task sequence has failed with error 0x80070035. This is a problem with all model computers even in vmware.
Has anyone experienced this problem? I've seen other post before and the solution was always to bump up the lease time which the network guys won't and probably can't do. It is like the IP will not auto renew while downloading an image. This happens whether you do download as needed by task sequence or access content directly. We are in native mode, but had the same problem in mixed.

We need to be able to image bare metal computers from anywhere on the network so using a dedicated vlan is difficult. The requirement for network registration during the setup process has been a problem for years, but with little resolution between the techs and the network guys.
We are using public ips for clients because many years ago the routing hardware couldn't handle the NAT translations for the large number of clients. The network guys don't have dynamic vlans configured although I think they are working on it right now they just piggyback subnets on interfaces. Also the separate vlan for loading computers would be partially difficults since this has to work any all buildings, but because of potential routing problems they don't put a vlan in more than one building. Each building right now has at least 1 dedicated vlan with a corresponding subnet and router. Most of our core is 10Gb with at least 2Gb-10Gb to each building so bandwith usually isn't a problem. The DHCP server is old, but handleing the work load just fine.
Our environment doesn't 100% match the typical corporation that runs configmgr. We have a primary central support area and then many sub support areas that all do their own thing with special image requirements. There is a need to keep these areas separate, but centralliy manages with minimal administrative overhead. So to handle this we use unknown computer support just to make booting with pxe into PE. I then use tsconfig.ini to call a modified version of the unknownsystem.hta from the configmgr sdk. The tech doing the imaging logs into this screen and selects an image collection (the available list is based on the users rights to the collections), ad ou, custom variable settings, and machine name to add the computer to the system and recieve the appropriate os advertisements without having to add the system manually through the configmgr console.
We are still working on ways to avoid the network registration step or register the computer on behalf of the client, but would still like to figure out this problem.
Thanks,
Sam

How do I get rid of second 169.254.x.x IPv4 address on Windows Server 2008 SP2 x86?

I'm sure this is an obvious one but can't figure it out.
I have a Winserver 2008 Sp2 (x86) DC with a static IP address allocated to its only NIC. It seems to have acquired a second 169.254.x.x address automatically which I can't get rid of and which intermittently causes DNS problems (and possibly other)
problems.

Any ideas as to how this might have happened and how I get rid of it (a simple re-boot doesn't do the job).

OK, I followed Syed's instructions. I noticed that under the registry entry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\ there were two AdaptorGUIDs, but only one of them had any parameters.
I created the IPAutoConfigurationEnabled parameter for both these AdaptorGUIDs with a value of 0 as instructed and re-booted.
Here are the registry entries for the two AdaptorGUIDs:
After re-booting I did another ipconfig /all, and the APIPA address is still there! Here's the ipconfig output:

[it's a different APIPA address this time, but I guess it is randomly allocated].

ACS 4.2.0 AAA-server-IP-address changing to 169.254.x.x

Hello,
I have ACS 4.2.0.124.15 installed on a windows server 2008.
In the configuration menu : network config > AAA server , the AAA-server-IP-address change to 169.254.x.x each time I disconnect the ethernet interface of the server.
Allthough, the ip adresse in my network connection of the windows-Lan-connection is set to static.
Whe I reconnect the ethernet interface of the server, it stays in 169.154.x.x. And I need to reconfigure the real static adresse each time.
Do you knows this problem. Is it a way to avoid it ?

IP address 169.254 or no IP Address

I have a Linksys WRK54G (model with one antenna). I have problem with IP address.
If I enter with DHCP on the adapter, it receives an IP address like 169.254, which is not accepted by the Linksys. If I enter with static IP address the connection is very instable, some times I have to disconnect the USB adapter and connect again, or even disconnect the power of the router, to get an access to Internet. That means the IP address on the adapter is either wrong or empty. The Firmware Version is 1.55.02, May 21 2004, and I believed that there is not update.
The Radio signal appears as excellent, no surprise because the distance between adapter and router is 5 meters and there is only one conventional wall.
I have tried all of the above:
- uninstall and install the router configuration
- enter with WEP with open authentication, and work also without WEP
- change the channel to 11, the beacon interval, RTS, etc.
I did not try to disable the APIPA.I believe the newtork shoud work properly with this as usually (Am I wrong?).
The problem affects not only desktop PCs with wifi adapter but also LapTop with integrated wifi.
I see that many users have the same problem with different Routers of Linksys.
I would appreciate any assistance anyone may offer. Thank you in advance for your time.

only your wirless computer with the adapter cannot get an ip address?or all of the wireless computers?
if your router has a working computer wired then it must connect wirelessly as well.is your wireless adapter linksys as well?
try to update the drivers for your adapter and try to check if other wireless computers also can't grab an ip from your router.. then if not there is really something wrong with the wireless settings of the router

Why Windows 8 and Windows 8.1 (Even Windows 7) detects ip network address 169.254.201.217/16 on my computer???
I keep getting that most of the time.

TS3798 How do I stop my ethernet connection assigning itself a 169.254. ... address?

How do I stop my ethernet connection assigning itself a 169.254. ... address? My iMac is connected to a wired network. The DCHP server is set to allocate the iMac the address 192.168.1.2 but the iMac seems to over-ride this and allocate a 169.254 address. How do I stop this please?

Shouldn't be a need to use manual.
First try renewing the DHCP lease. In Network preferences, ensure the location in the top drop-down is set to Automatic, then click on advanced -
Then click on 'renew DHCP lease'. It may help to turn of IPv6, too, as some routers can't handle it yet.
