Self Assigned IP Address redux

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

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

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?

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.

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?

If 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.

My macbook air will not connect to the internet due to a self assigned IP address. I have tried trawling the support forums, but either I can't understand the suggestions, or they don't work. Please explain to me in simplest terms how to fix this. Thanks!

The warranty entitles you to complimentary phone support for the first 90 days of ownership.
If you bought the product in the U.S. directly from Apple (not from a reseller), you have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different. If you bought from a reseller, its return policy applies.

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?

Rebuilding aMacBook 1.83 GHz Intel Core Duo, hard drive failure so rebuilding system. Aircard will not stop self-assigning IP address. Any ideas how to resolve successfully?

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?

Self Assigned IP Address with Airport Extreme

I just changed my router from an Asus to AIrport Extreme.   The Airport Extreme is connected to an ATT DSL modem. I know the modem works because I can connect to the internet when I connect it directly to my IMac. However, when I try to access the internet through the airport extreme it connects temporarily and then loses the connection. It tells me that I have a self assigned IP address and cannot connect to the network. This is the case through both Ethernet and WiFi. It is also the case when I try it with other devices (e.g. IPad, MacBook).
I know there are lots and lots of threads in this forum (and others) on this topic. I have been pouring over them for days and trying everything I could find including but not limited to--
Rebooting/power cycling
Keychain clearing and repairing
Renewing DHCP lease
Turning off firewall and virus barrier
deleting and recreating network
The modem is set up based on the ATT instructions for when it is to be connected to a non ATT router, thus it is in Bridge mode and the Airport Express is set to use PPPoE.   OS and all firmware is up to date.
There is another issue which may or may not be related. It is also an issue for which there are many existing threads (but apparently no definitive solution). My Imac keeps giving me a message that the name of my computer is already in use and has been changed to.....
http://https://discussions.apple.com/thread/4207056?start=0&tstart=0
I have tried several suggested solutions (e.g. energy savings pref, using only wifi or only ethernet to connect). So far no luck.
Both of these issues seem to have started when I switched routers.
Anyone know if the two issues are related? And whether there is a solution? Seems like both issues have been around a long time.......

Was using the wrong password option in UIXperts driver. Kept thinking it was a different protection mechanism than it was. Once the password was set, all was well. Referred back to the IOXperts installation guide (RTFM) for a clue.

"self-assigned' IP address.

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

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

Self-assigned IP address 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! :]

Self-assigned IP address, try to connect to pc

I do a lot of file transferring from my mac to another pc laptop, so I've got them hooked together with an ethernet cable. I had this issue in the past, where I'd try to connect but my network settings kept saying the "ethernet has a self-assigned IP address and will not be able to connect". The solution I found to fixing this was to open up the Advanced Settings, and change the IPv6 configuration to "Link-local only" and then everything would work perfectly.
I upgraded to Yosemite yesterday, however, and now that solution no longer works. Still getting self-assigned IP. How can I fix this??

I checked my sharing options, and everything looks to be on. I also have the yellow circle, but I can never get a connection unless it goes green. Before I upgraded, that was the issue before; it would be yellow until I changed the IPv6 connection to "link-local only" and then the ethernet connection would change to green, and I'd have no issues. Now, when I change it to "Link-local only" and hit apply, nothing happens, it's still yellow.
I tried to connect to the server just to see, and it won't connect. I get an error that says "There was a problem connecting to the server "AMANDA-PC" Check the server name or IP address, and then try again. If you continue to have problems, contact your system administrator."

I took the following from the Aztech website:
8) Can Aztech HomePlugs work with Apple MACs?
Yes they can, Aztech HomePlugs work with Apple MACs. However, there is a requirement for using the Utility software. The Utility software will only run on Microsoft Windows 98SE / ME/ 2000/ XP/ Vista.
Which contradicts itself, if the Utility is required but only runs on Windows, how does that work on a Mac?

Self assigned IP Address, wireless doesn't work

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

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

Can't connect wireless due to "self-assigned IP address"

I recently switched from PC to Macbook. I cannot log on to many wifi networks I could previously access with my ThinkPad. The computer successfully finds the network and has a strong signal but will not connect. Under network status, I get a message that says something like "Your Macbook is connected to the wireless network but AirPort has a self-assigned IP address and may not be able to connect to the network."
Ive tried various options but still no luck. This mostly happens in public Wi-Fi networks such as internet cafes, airports and Starbucks' T-Mobile networks. Thanks!

Can you connect to any wireless location? Or does not fail only in certain places? If you can't connect anywhere, it is your problem. If you can connect in some places but not others, it is their problem.
It wouldn't surprise me if there is some new, cheap vendor of wireless access points that doesn't do the network settings correctly and only Windows machines will connect to it.
You were a ThinkPad owner, so you weren't a typical PC user anyway. Most of them use PCs only because they are cheap, cheap, cheap. Is it 3.29 cheaper than a Mac? Buy it! Those people are now making cheap wireless access turnkey solutions. I have seen people like that before. Just because there are hundreds of millions of pounds of equipment depending on the software, or people's lives, doesn't mean they know how to do networking. They may be so incompetent they don't know they are incompetent. Those types typcially would never, ever think to test their product on a Mac.

Can't get rid of self assigned IP address

Hello,
I have been trying to resolve this problem by myself for the last 4 days (by googling and reading forums) but nothing works so here I am.
I moved last Tuesday and everything worked fine until that day. Since I am in my new apartment, I can't connect to the Internet because of a self assigned IP address. Here is more info:
-I have a new modem since I moved (the apartment where I was living was furnished and had a modem already). However, I am using the same service provider and modem than the apartment I was subletting.
-I only have a modem (no router) and I use the Ethernet to connect.
-I am writing this message from a PC laptop which confirms that the modem is working fine and that the ethernet cable is fine, etc.
-I did many rounds of shutting down the computer, renew DHCP, unplugging the modem (from 1 minute to 10 hours) and plugging everything back.
-I called the ISP but they could not help (they just repeated the same instructions that I could find in the guide)...They have no idea how I can get rid of the self assigned IP address.
The problem is still the same, I can't get rid of the self assigned IP address (169.xxx).
Please help if you know other tricks to fix that issue...
Thanks a LOT in advance!!
Julie

Re 1) Setting up a new account won't solve the problem in itself but it will help narrow down the cause. The idea is this: the problem might be caused by something system-wide (e.g. a preference file in /Library/Preferences) or it might be caused by something that is specific to your account (e.g. a preference file in yourhome/Library/Preferences). If we knew which, we could target the troubleshooting appropriately. The easiest way to figure out which is to create a new user, log in as that user and see if the problem remains. If it does, it must be system-wide; if not, it is specific to your account.
Are you using any firewall software? If you are using Tiger's built-in firewall, how is it configured?

Can't connect to internet..self assigned ip address problem with DSL Modem

I've run into this before, without resolution, and now again on a friend's iMac. Time to ask around...
Basically, everything appears to be assigned and configured perfectly, but the network status always shows, "...you have a self assigned IP address and may not be able to connect to the internet". Sure can't connect to the net when it says that.
I've gone thru the procedure advise before that details the sequence of events needed to insure the modem resets and recognizes the Mac and it's incoming DSL (sbcglobal) signal. The order of network priority is set properly by dragging built in ethernet to the top of the list. Modem was powered down, plugged in, and then connected to the Mac, but no solution. Any ideas? thanks

This continues to be a mystery. I've had my powerbook on several networks, and connection has, most of the time, been an automatic process. Additionally, I've installed new systems for people with the same isp, and all has been well. So easy is the process, it's never been an issue. However, following explicit procedural instructions (including powering the Mac down), has proven unsuccessful on 2 different occasions.
There is little help with the isp support in India, which is where the call routes too.
The only thing I have not done is to swap out the cable at one of the locations, but the other location, which has the same issue, works fine on the iMac there. Only when I connect my Powerbook to the modem, does the "...self assigned ip address...not be able to connect to the internet" appear.
I just keep thinking there has got to be a small detail that is being overlooked.
