Self assigned IP address partial SOLUTION

Hello there, dealing with the nasty issue of "self assigned IP address" has been my latest two days nightmare, I tried lots and lots of solutions I read in forums here and there without getting to a point.
I started this post because I want to post here a solution that really worked for me and I haven't seen it posted over the web.
I don't remember where but I saw the comment that WEP encryption by the router is not very mac compatible as opposed to WPA. So a while ago when I entered my router home screen (Thomson TG585 v7) I saw the option to enable WPA-PSK encryption and went for it, I can tell you it inmediatelly solved my conection issues and till now it's working perfectly.
I'm not any mac/web guru but I want to share this tip with all of you because I know it can be a really nasty problem that one of the gat dam "self assigned IP address" and this may help somebody else. ;-)

All of a sudden I started getting "Self-assigned IP address ... Can't connect to internet" message when I attempt to connect to wi-fi at home. I tried solutions posted on the net but to no avail.

It once worked when I removed it from Network preferences and attempted a relogin - but the problem resurfaced again and is not going away. I tried the "key chain access" solution - but my Wi-Fi doesn't show up in "Sytems" at all. Any help will be appreciated. It's OS 10.6.9 MacBook Air.

The wifi icon shows no connection with the network -- the "!" mark.
However the computer sees the network, i.e. when I search in Network Preferences the network is listed.
So: 1) the computer sees the network but 2) will not connect to the network. The reason given for refusal to connect is "self-assigned IP address".
Not to be repetitive but two other Mac laptops are connected to the same network and working perfectly. The network preferences, as shown in the "advanced" section, are the same for all machines, i.e. DHCP is selected and IPv6 is Automatic.

Self-assigned IP address problem - My solution

I am new to this board and created an ID just to write this post. When I searched for this self-assigned IP problem, I found almost 1 million results on Google so obviously I am not alone.
I have this problem off and on on the wireless network at home with a Netgear router. It has never happened at my office with a D-Link router. Never happened at Starbucks or McDonalds (yes, they all offer WiFi here). But it happened at one Pizza Hut and it also at Christchurch airport about a week ago.
Deleting one of the plist files worked once at home many months ago but this week nothing worked. My Mac usually goes back to normal by itself after I "****" it out at other WiFi networks but not this time. As a last resort, I asked my brother (our family's I.T. guy) to change the router as I had not tried that fix. He didn't do it but a day later, he gave me to oddest solution that worked in a blink of an eye.
The solution? Key in a wrong password!!!
1) Go to Keychain Access, delete the keychain for the problematic network.
2) Connect back to the network
3) Enter a WRONG password that is similar to the right one. For example, if your password is Apple123, try APPLE123. You should still connect to the network and get a self-assigned IP.
4) Repeat Step 1. To be safe, you might want to re-boot now. I did but probably didn't have to!
5) Repeat Step 2
6) Enter the right password
I'm not all that techie so all I understood from what he said was:
1) It's probably a non-Apple router bug
2) It's a hex key problem. The password wasn't being encoded/decoded properly so the router wasn't assigning the computer an IP address. Wasn't even reading the password which is why I could connect with a wrong one.
He deduced that from reading a post from a guy in Spain who thought he had carelessly entered the wrong password and was wasting the community's time with his posting. I had read that post a couple of days ago too! But obviously I thought the Spaniard had just entered the wrong password and there was no fix for me to try out. My brother is a genius!
I guess it then makes sense why fixes like:
1) Disabling the firewall
2) Deleting preference lists
3) Deleting keychains
4) Changing the router
5) Renewing DHCP lease
6) Resetting the router
...have worked for many people and not others. None of them actually fix the cause of the problem. Having searched for 3 days, I could not find the REAL reason why this happened. Personally from all I have read, I think it must be a hex key problem with Netgear and Linksys routers. I see those 2 names mentioned a **** of a lot. Maybe it's another one of those gadgets built more for PCs that don't work perfectly with Macs all the time. We used to have an Apple Airport Extreme base station but that got fried by lightning. It was not cheap.... So technically, it really isn't Apple's problem. I think if we used an Apple router, we wouldn't have a self-assigned IP address. Maybe that's why they haven't "fixed" the problem after so many years.
Anyway, let me know if my brother's fix worked for you.
This is my good deed for the weekend! Goodnight....!

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 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

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."

Self-assigned IP address issue after upgrade

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?

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 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.

Airport and a self-assigned IP address - can't access wireless net

I have a strange issue with Airport picking up a wireless network.
I'm not in my usual location using my MacBook Pro.
There is a wireless network here.
Airport sees it, and asks for the password (provided to me).
Airport looks connected, but, I see the message: "Airport has a self-assigned IP Address and may not be able to connect to the internet".
And in fact, it cannot. I've run through the diagnostics routine twice, and no go.
How do I get Airport to accept an IP address from this wireless configuration?

I am having a nearly identical problem. The solution provided did not work for me.
We have two MacBook laptops, one is mine and the other my wife's. My laptop still works fine. The AirPort communicates well with the wireless router. My wife's laptop just started having this problem about a week ago. The latest Airport software updates helped, but did not solve.
The problem is that I now have to go into network diagnostics everytime to connect my wife's laptop to the wireless router. I have to re-enter the password to the router each time. Once I enter the password, it finds the IP address and connects everything properly. I checked the keychain password and it is there, so I don't know why it keeps losing the IP address.
One thing that I did preceded this problem. I changed my router password to WEP. If anyone knows if this could cause the problem, let me know.

"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.

How do I solve a self-assigned IP address?

Hello all,
Here is the situation: I am currently on the road with a MacBook Pro running 10.6.8 and an iPhone 4 running iOS 5.0.1.
The hotel where I am staying doesn't have WiFi, but does have ethernet cables in all the rooms. My laptop is therefore hooked up to the internet through its ethernet port. No problem there.
Way back when, I used to be able to share that internet connection with my dataless iPhone (I don't use data while travelling internationally as I'm not made of money), but going to System Pref>Sharing and sharing the internet connection, which is incoming through the ethernet port, through the AirPort. One day, it stopped working, reporting that the AirPort has a self-assigned IP address (in the dreaded 169.254.xxx.xxx range) and will not be able to connect to the internet. Hence my iPhone won't get its internet feed. I have looked all over for a solution and haven't been able to find one where the problem was similar to this one; those posts I found dealt with computers trying to hop onto the net directly, not with sharing a net feed.
I would be extremely grateful for a solution.
Many thanks!
Carl

Power cycle your router.
