Self-generated IPS address

Hi,
I have Airport Extreme on G4 with OSX 10:3.9. On open networks, (such as in a coffee shop) I get on no problem. But in some homes with wireless base stations I can't get on, no matter what we try. I keep getting the message:
"Airport has a self-assigned IP address and may not be able to connect to the Internet."
I travel a lot and this has become a real problem. I've tried everything to try and figure out how to make my Airport receive the IP address assigned to it by the base station, but with no luck. Does anyone know the secret?
Thanks so much!!!
Blake

Blake,
It sounds like your Airport Extreme base station isn't getting a valid IP address from your ISP. Is the ethernet cable from your cable/DSL modem going to the WAN port and not a LAN port on the base station? If it's a cable modem going to the WAN port then you may wish to review knowledge base article http://docs.info.apple.com/article.html?artnum=106836 to see if perhaps MAC address provisioning is being performed by your ISP.
Regards,
Chris

Do you have "ask to join new networks" enabled in System Preferences / Network with the "Airport" option in the left hand pane selected, Dale? If not, try enabling it.
Is Airport the "top" option in the left hand side of the Network panel? If not, try shifting it to the top using the "Set Service order" option (available through the "rosette" next to the "+" and "-" buttons.
In the System preferences /Network panel, with Airport selected on the left, If you click on the "Advanced" button and select the TCP/IP tab, do you have "Using DHCP" selected in the IPv4 box and "Automatically" chosen in the IPv6 box?
How are you going about seeking to join the networks? (the process can vary depending on the provider)

Bizarre WiFi Connectivity Issue; Self-Assigned IPs, Static IP Doesn't work

The short and sweet of the problem: Macs/Apple Devices are pulling self-assigned IP addresses when connecting to a Linksys EA6900/AC1900 router.
Here’s the detail: I am working at an office with 1 Airport Extreme and 1 Linksys EA6900/AC1900, both are configured for Bridge Mode and both use WPA. DHCP is being handled by a Watchguard XTM5 series firewall.
When Macs (and often iPhones) connect to the Linksys (on 2.4 or 5Ghz) they get a self-assigned IP address. If you enter a manual address you still do not have any connectivity. However, if you connect to the Extreme you will instantly get an IP address, and if you switch to the Linksys your DHCP address will carry over and you will retain connectivity. This problem does not happen to the Windows machines in the office- they all connect to all base stations without any issue. Total users on the network range from 5 to 20 WiFi users at any given time plus and AppleTV (also affected).
More info: When there are between 5-10 people in the conference room for a morning meeting the Macs will all revert to self-assigned addresses (even if they were working before). The workaround has been to connect to the Extreme, but there are occasions when this occurs that the Extreme will also not seem to pass the DHCP addresses from the firewall; addresses become self-assigned and you lose all internet. To make matters more odd, this behavior seems to really only affect the network during business hours; after hours the Linksys works pretty much normally and any device can connect without issue.
Things I’ve done: Run Wireshark and located a number of rogue devices that were handing out overlapping DHCP addresses. Identified machines that were ARP storming and removed them. Expanded the DHCP pool so that we aren’t running out of addresses and confirmed that we had enough by checking the logs.
More things I’ve done: Used Netspot to check signal strength and channel overlap and isolation. I have mapped the signal strength by location and we have strong signals to the various locations (the Linksys AP is 7 feet from the conference room). I have checked that the firmware is the most recent version.
I can’t find any logical reason for the Macs (and pretty much only the Macs/Apple devices) to not be picking up DHCP info through the bridge mode devices. I would tell them to get another Extreme but they are going to be deploying a Cisco Meraki system soon and I suspect that this problem will persist since the Linksys was put in place because the last AP displayed the same behavior with the Macs picking up self-assigned IPs. Affected Macs range from 2010 era MBP and Air to 2013 MBP and Air and they are running OSX 10.8 through 10.10.
As for the history of this network, I just walked into this company and know very little about how well it worked before, but apparently it has always been flaky according to the staff.

I agree that something isn't right; I am going to cut over DHCP services from the Watchguard to the newly deployed OS X Server tonight and see if that changes anything.
On the other hand, faulty DHCP server/client settings doesn't explain why applying a static IP still leaves you with no connectivity. I think that clue is also fairly important but I can't figure out what would be blocking connectivity on a static IP setup.

Help! How do i get rid of self-assigned IP address? Virgin Media & Ibook

Hey all, first time here. Hoping someone more knowledgeable than me (or the people at virgin!) can help.
I have home broadband from Virgin as of last night. Self-set up the modem (Cisco), Router (D-link) and connection to my Ibook, running Tiger 10.4.11
Router and modem seem to be working fine. Green lights all round. Plus last night i had an ethernet connection runnign fine and even got a wireless connection to the Ibook. All good.
This morning, twenty minutes of internet use, then bumped off. No connection.
Checked under System Preferences, Network, Airport and got a message saying Airport has 'a self assigned IP address and cannot connect to internet.'
I assume the problem therefore is with the Ibook talking to the router (sorry, not very technical so 'talking' is best i can do).
Tried switching off the firewall. Still no joy. Airport can see my router in the list, and even has it first in preferred networks to join list. I get a five bar signal when i select it from Airport but how do i rid the computer of the 'Self-assigned IP address' ?
Please help, it's driving me mad! Apple blame Virgin, Virgin blame Router manufacturer, Router manufacturer blame Apple. It's an endless circle of **** and call-centres!!!
Cheers!

Hi Dan, and a warm welcome to the forums!
"self-assigned IP address" simply means it's not getting an IP from the device responsible for handing out IPs, the Router in your instance.
Does Ethernet still work fine?
Go to System Preferences
Click Network
Highlight AirPort and click Configure...
Choose “By default, join: Preferred networks”
Select your access point and Remove your access point with the minus button.
Launch your keychain access in Utilities and delete your access point keychain entry.
Reboot
Go back to the “By default, join:” page and click the plus this time to add your access point. Enter the correct password, save, reboot.

Reload config file bug to be mindful of self assigned IP address

I did a an export of the config of my 4 routers, then reset them all to factory defaults, then reloaded all the config files.
All the outlying routers were non connectable and had yellow flashing lights. I connected to each manually with an ethernet cable and laptop and found that each had a self assigned IP address.
I went back to the main router and found that the check mark to allow the network to be extended did not re-check during the config file restore. Once I manually checked the box, all the routers automatically came on line.

Hi mpedruski, and a warm welcome to the forums!
The "self-assigned IP address" simply means that it is not getting a reply from anything like a Router handing out DHCP IPs.
The Interface that connects to the Internet, needs to be drug to the top of Network>Show:>Network Port Configurations and checked ON.
Might pay to make a New Location for each...
Sometimes having an all OFF Location can help, thanks to Gnarlodious...

My ipad recognizes my home network but will not connect to the internet. When I click on AirPort/preferences at the top of the imac screen it says..."AirPort has a self-assigned ip address and may not connect to the internet".How can I change ip address?

My ipad recognizes my home network but will not connect to the internet. When I click on AirPort/preferences at the top of the imac screen it says..."AirPort has a self-assigned ip address and may not connect to the internet". If this is the root of the problem,how can I change ip address?
Ipad will connect no problem to other networks.

First thing you need I think is to get your iMac connected to the Internet.
Shut down your iMac and you iPad. Then power off your router. Wait 30 seconds and power up the router.
After the router indicates that it is connected to the Internet then start up your iMac and see if it connects. If the iMac connects to the Internet then your iPad should too.
If this power up sequence doesn't work you'll have to dig into the router setup to make sure it is working properly.

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?
Charlie

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.

How do I stop Firefox from redirecting me to another site based on my IPS address?

I work in California. Our corporate offices are in Oklahoma and my desktop computer is set up with an IPS address in OK. When I try to go to the CA website for AAA, Firefox redirects me to the OK website for AAA. How do I stop from being redirected to OK sites when trying to open CA sites?

hello eajames, sites can show you content and redirect you based on your IP address which will reveal your approximate location - there is not much a browser can do against this...

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 Generated certificate validity issue in ACS 4.0 for Windows

Hi,
Is there any solution to extend the validity time of self generated certificate on ACS, by default the validity is set for one year.
As the server certificate on one of the ACS which is CA has expired and need to renew it.
Is it possible only one certificate from third party can be used both as a server certificate and certificate from CA for other ACS servers.
Thanks in Advance
Regards,
Ahmed

Other solution would be to create an in house(Microsoft probably) CA, and get a certificate for your ACS server. Go through the installation steps of Microsoft CA before, as the validity date for Server Certificate(i guess) is configured during initial install of CA.

Prem

"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
