Can't delete a self-assigned IP address...

Hi folks,
I am using an circa 2005 iMac G5 PPC desktop with 10.5.8. I am trying to connect the iMac to my Time Capsule via ethernet cable, but seem to be having problems with my ethernet card. When I plug into the TC ethernet port, the TC drive, does not mount and I cannot access the worldwide web.
When I go to System Preferences --> Networking, the tab on the left for ethernet connection shows a green dot, says "self-assigned IP" and the status says "connected" PRIOR TO CONNECTING THE ETHERNET CABLE TO THE TIME CAPSULE. It shows a "self-assigned" IP (DHCP selected) of 169.254.69.249, even though I know my TC is 10.0.1.1. Turning the ethernet off then back on, renewing the DHCP lease, nothing seems to be able to make this 169 IP address go away. The wireless connection to the TC is just fine... everything does what it should, I just can't get the ethernet cable connection to work.
Out of curriosity, I went to the System Profiler, and on the network tab it shows ethernet IPv4 169.254.69.249 (name en0).
I know it's not the Time Capsule, as I connected my laptop to it just fine via ethernet. The TC was IP 10.0.1.1 and it assigned 10.0.1.5 to my laptop (I have a variety of devices on my network), and I was able to transfer data and access the internet with no issues whatsoever.
I live in an 32 story apartment with a built-in ethernet network and ISP included in my rent. It's pretty nice, high speed. I connect from the wall to the Time Capsule via ethernet (circle dot connection port, so I know I have the right port), and then wirelessly out to a couple of laptops, a couple of Airport Express, and of course my desktop.
Bottom line, I think the ethernet card on iMac G5 desktop has gone bad: A few questions:
(1) Any ideas what may be wrong? Has anyone seen this self-assigned IP thing that won't go away?
(2) Any ideas how to fix it?
(3) How much will it cost? It may be time to replace my 6-year old desk top computer.
Thanks, Andy

Ethernet has a self-assigned IP address and will not be able to connect

Other computers with same hardware and software (MacBook + 10.6) can get online using the same DHCP cable normally but mine can not. The self-assigned IP address refuses to go away no matter what I do. However, if I connect via wireless, everything is normal.
My 10.6 was upgraded a few weeks ago based on 10.5. Things were normal and Ethernet DHCP did work. This network problem suddenly appeared when the computer was functioning completely normal under a DHCP protocol using a cable.
Does anyone observe similar problems? Anyone has any clue about what's going on?
Thanks much!

try this. i had the same problem. found this on another forum:
1. Go to Mac/Library/Preferences/SystemConﬁguration
2. Delete the following:
a. Com.apple.airport.prefrences.plist
b. NetworkInterfaces.plist
c. Preferences.plist
3.Shut down computer
4.reset PRAM (hold commandoption+PR keys down before gray screen when booting up)

Help! Need to release self assigned IP address

This is my daughter's CPU...I tried the renew DHCP lease, restarted the iMac (G3, strawberry 266 MHz), cable modem & router and still the stupid static IP address still shows up! I called the ISP and tried many of these standard fixes, I even reinstalled OSX Panther and the problem remains. It used to work well until I put the CPU away for couple of months and when I tried to reconnect through Comcast, it did not. Please help me!!!! >_<<br>
iMac Intel Core Duo Mac OS X (10.3)

the only thing u can do for a self assigned ip address is power cycle the modem for 5 minutes, make sure the LED lights are out.. some modems have batteries... if that doesnt work try creating a new network location.. if that doesnt work then you will have to call your internet service provider
you could trying booting to your install disc and running network utility there but yes..

MacBook has self assigned ip address and cannot connect to the internet.

Is there an Apple recomended fix for this problem that works? I've looked on this board and have found several similar suggestions but as yet nothing that results with consistent connection every time I restart.

Since there is no exacting way to tell what of several suggestions offered in
these discussion boards, you may have tried, I will offer an Apple Support
article name and web address link; it may be you have tried this:
• Mac OS: How to release and renew a DHCP lease
http://support.apple.com/kb/TS1920
And you can get a similar self-assigned IP address via a wireless network
or a wired local network - with a theoretical connection to the internet. If
the actual connection in software is not set correctly, the default will likely
be something very familiar since the same one appears then.
If the Network system preference panel is set and you have chosen the
mode of connecting to the internet or other connected network, then
you can set the configuration of that choice in a secondary screen. In
order to have a choice to connect via AirPort, for example, you have to
check box the item and also drag it into a position of priority (first.) Or,
if you have to connect via Ethernet to a cable/DSL modem (if not USB)
you can choose to place Ethernet in a position of priority above others.
Then, further the Network configuration's next step to set it up correctly.
The above link does cover the basics adequately, including a reset of
the cable or DSL modem. If there is a cable modem and also a wireless
base station, you may also have to reset each of them in a specific way
in order to get them to start up and work. This may be all it takes.
Good luck & happy computing!

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.

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!

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.

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.

Ethernet cord has a self assigned IP address, can this be changed?

I am trying to connect my laptop to my Xbox 360 so I can get on Xbox Live using my computers wireless as a gateway... but the ethernet cord has a self assigned IP address and won't work.. I've tried everything to change it and it still won't connect with my router. It is a cisco router.

Welcome to Apple Support Communities
You stand a better chance of a connection if you set the Ethernet interface to DHCP and have it be assigned an IP number by the Router ...

Airport: Self-assigned ip address, can't connect (public routers only)

this has been talkeda bout before, but is extremely frustrating, because i don't have the problem with a PC.
1/2 of the public routers i connect to have some kind of login page, most the time they just say "youre getting free internet, click here" ... but sometimes that login page never comes up, and the network card says "airport has a self-assigned ip address and may not be able to connect to the internet"
this only happens on pulic routers for me, and only ones that have login pages.
its very odd because for example, starbucks has all the same routers, all are "attwifi" now .. i go to one, i get hte login screen, go to a different one, i don't get it...and can't connect
with a PC, i get it every time.
this is undoubtably a leopard problem, that needs to be fixed. please!

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 -- can't connect to Airport

I have a 2006 MacBook Pro which recently started exhibiting the exact same behaviour as reported by another poster in 2011:
For some reason the computer has started self-asigning its IP address and Network Preferences says that, because of the self-assigned IP, i cannot connect to the network.
I have two other Macs connecting to the same Air Port with no issues and I've tried to duplicate those settings on the MacBook Pro but still get the "self-assigned ip" message
Tried re-setting SMC and PRAM, no change.
The only change to my wireless setup was the change from a Verizon-owned modem to an owned Motorola unit (but the MacBook Pro connected successfully, many times, after the change).
I didn't knowingly change anything on the MacBook Pro -- from one day to the next it just stopped connecting.
I'm really at a loss to understand what's going on and, of course, not happy that the MacBook Pro can't connect to my network anymore! Help!

Self Assigned IP address, can't connect

In a few instances, I will join a network, be shown as linked to the network. Then when I look at the network status page, it reads "you are connected to the internet, however the provider has a self-assigned IP address & you may not be able to link up". Can anyone explain what to do in this situation.
Much love & thanks,
Jackson

Is the network not working at this point? What method of IP address assignement is currently selected?
