Self Assigned IP Addresses amber lights and no internet HELP!

Ok bear with me as I try to explain my prediciment!
I have an imac G5 with a Airport Extreme card properly connected and currently at full signal! The problem I'm having is that when i click safari (or IE) it doesn't load up any pages and a littke box pops up saying that it cannot find the server! so I go to network settings in system preferences and check the network status. I have an amber light and it says "airport connected to (my server) IP address self assigned your mac may not be able to connect to the internet" the problem is it is not self assigned it is done through DHCP.
I have had internet working perfectly at another house and it has worke don the odd occasion for a couple of days here so I don't think its a fault card (as i say it picks up a signal fine). I have tried putting in all info in manually but this has not helped (although on 1 occasion it did). I have baffeled the university technician with this problem. Im currently using ethernet to connect but this is no good as I need the computer in my bedroom and not the dining room (student accomodation) if you have any suggestions or have experienced this problem yourselves i would be delighted to hear of any answers and suggestions!

Hi,
Duane is right in that if ACL's (access control lists) are set on the wireless access point, (as they are in my school) you will need your mac address of your airport card to add to the router.
Here's what I would do.... Open up Network Prefs in the System Prefs app. Create a "New" location and name it whatever you want ("Wireless at Home"). In the "Show" drop down menu, select airport. You should see 5 tabs in the airport window. Airport, TCP/IP, PPoE, Appletalk and Proxies. Click the airport tab and select automatically where it asks you what default network you want to join. You'll also find your mac address for your airport card in that pane. Next, click on TCP/IP and select DHCP from the IPv4: drop down menu, make sure no information is showing in this window. In other words, no numbers in DHCP or DNS servers, etc. If it's blank and ready to go, hit apply. The router should then hand off an IP address. Close system prefs and look in the menu on the upper right hand corner of your screen (by the date and time). See the airport fan? Does it have black bars through it? Or are they grey? Or, does it just look like a blank semicircle (airport is not turned on). If you don't see this menu, go back to network prefs and open the new location you've just made and go back to the airport tab. There is a check box in there that says, show airport status in menu bar. Turn that on. Now, go back to the menu and if the bars are grey, click on the fan and see if your network is listed there. Click on that to join. You have made a new location with fresh DHCP settings and told your airport card to connect automatically to whatever network is available.
Your tech guy at school is probably a PC head and that's why he's been stumped. He shouldn't be.
Hope that helps.

Hi, the one below worked for my case.
I beleive there are different reasons for this problem. In my case, doing try and error, I found a solution for my case (at the ver end of this post). The reason I say this is because I had the same problem and googled the problem for quite a while ... none of the suggested solutions worked for me, although it seems like they worked for others in some cases. I tired taking my computer to different wifi networks (mainly unprotected ... ie no WAP) and alwasy got the same problem. I even took the computer to apple and no luck ... surprisely when I took it to apple it did connect to apple's wifi network in the store, so according to them it was probably some problem with my network ... when I walked out of the store I tried connecting to another open network in the mall and got the same problem ... went back to apple and they tried a few things without any luck (however it would connect to apple's network)
Of all the solutions I read the one that made more sense for me was the one related to keychain access, although in my case I had the problem trying to get into an unprotected network, which at some point was protected.
So this is what I did: among other things I compared the keychain access file with that from another macbook that was working ok, and I noticed that although my wifi network is unprotected there was an entry for it in the keychain access list (maybe from the time that I had the network protected with the deafult config from the router). So I went to network preferences on the computer that had the problem, went to advanced and selected the name of my network (configured without security), and changed it to WAP personnal security, and entered the previous access code from my router --- the same configured in the other mac keychain file ---. This created an entry for my network in the keychain access file, just as it showed in the other macbook. I then went back to network preference and change the configuration of my network back without security. AND NOW it is working, NO MORE SELF ASSIGNED IP ADDRESS. (remember that I actually I never really changed the configuration of my wifi router to make the network secured ... actually I didn't touch it at all .... well I did before some days ago trying to follow some of the suggested solutions, doing things like power cycle, reset to factory default etc, etc, which never worked)

Airport has a self assigned IP address. Why and how can I fix it

Airport has a self assigned IP address and can't connect to the internet. Why and how can I fix it?

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.

Ethernet has self assigned IP Address,will not connect to internet?

Ethernet has a self assigned IP Address and will not connect to the internet.
I am on - Mac os X - 10.7.5
Using a BT Broadband Router, my power mac is connected to the network via TP-Link Plug POWERLINE. This has worked great for ever!
A week ago, my web connection dropped, network settings say "Ethernet 1 is active and has a self assigned IP Address and will not connect to the internet"
This seems to be a popular thread and I have followed all the answers I can find and the problem remains.
I also run a Powerbook on the wireless internet and other appliances such as, iPads, iPhones, and the wireless is fine.
My sky box and Xbox 360 (both ethernet via TP-Link) also have NO connection.
When I turn my laptops wireless off and try the ethernet cable (tried a new one too) instead, there is the same SELF-ASSIGNED IP ADDRESS issue.
This point me to the router or TP-Link network. I have replaced the router, same errors.
On my Powermac I have -
Deleted 'system configuration from the system folder - as advised by apple.
Tried swapping from DCHP, DCHP Manual and renewing lease etc.
Could anyone help at all? I am lost now as how to solve the problems.
All my TP-Link power line extenders show the correct lights, i.e., all on and yellow.
I am not experienced in networks, this is driving me mad now!
Any help would be appreciated
Thanks

Open System Preferences/Network
Select the Location you use at home
You may need to click the Padlock bottom left at this point if it's locked, enter the admin password to unlock
In the left hand column drag the Ethernet connection to the top of the list and remove any you don't use
Click the Advanced button bottom right
Click the TCP/IP Tab
Set Configure IPv4 to Using DHCP
Click OK bottom right and you should see the Router IP number appear and a unique but similar one for your Mac
Click Ok then click Apply and close the Panel

"Self-assigned IP address" won't connect to Internet

I have two Macs connected to my DSL modem: a MacBook Pro (10.5.2) and a PowerBook G3 'Pismo' (10.3.9). Yesterday both were working fine, but just now when I started up the PowerBook it told me "Built-in Ethernet has a self-assigned IP address and may not be able to connect to the Internet." Indeed, though the cable is connected just like yesterday, there's no Internet (though the MBP is connected just fine).
Anyone have any idea why this happens, and what to do about it? I've tried disconnecting/reconnecting the cable, and restarting the PowerBook, to no avail.

Your router uses a system called DHCP to allocate an IP number to any computer connected to it. So when a computer is booted, the router recognizes its presence and allocates it a number. If the computer is running 24/7 the number's 'lease' is usually renewed every few days.
Sometimes the process falls over and the computer fails to get an IP number from the router: when this happens it allocates itself an emergency number with the results you describe. As you found, rebooting the router usually clears the problem.
It may be possible to reprogram the router and the computer to use a fixed IP number, it depends on the router. Very possibly this would prevent the problem occurring since both ends would 'know' what the number should be from the off.

Self assigned IP address will not connect to internet

Took iMac into Apple store, Genius tech confirmed wifi connection working in store. Cleaned out a few library files, suggested I go home and attempt to access wifi connection again.
All other Apple devices connect to Internet using WiFi connection with Airport Extreme, including one Windows laptop.
Occasionally the wifi connection on my iMac would drop out. In system preferences I would see the network there, select it, and was good to go. Not this time!
Went back to the Apple store to ask for help. Tech suggested I clean out "locations", so I did that. I also did manual set up using IP address on Airport, got message that wifi is connected but iMac not connected to Internet. Tried Diagnostic, Assistant, and nothing works. Wifi is working, I am on my iPad, but cannot get this iMac computer online.
Defaults to "WiFi has the self assigned IP address 169 254 167 148 and will not be able to connect to Internet
Under that message is Network Name and mine is shown. again: WiFi On, Alert: No Internet Connection, Apple Network selected and working.
How much does it cost to call Apple Support? I feel sure a grandson or nephew could fix this but no one lives nearby:-). Thanks for any suggestions.

Hold down the option key and select the Wi-Fi menu in the menu bar. What values are shown for the following?

HT3466 Airport has self assigned IP address 169.254.153.51 and will not be able to connect to the Internet

Cannot connect to internet wirelessly because I get the message "AirPort has the self-assigned IP address 169.254.153.51 and will not be able to connect to the Internet."

I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
Disconnect the AirPort base station from the Internet broadband modem.
While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
Power-up your computer(s).
In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.

Wi-Fi has self-assigned IP address 169.254.9.151 and will not be able to connect to the Internet

In trying to setup my AirPort Extreme, it connects to the Internet on ethernetcables to computer but says it is not on WI-FI. I have configured it with all that I casn think of and yet I get, "Wi-Fi has self-assigned IP address 169.254.9.151 and will not be able to connect to the Internet." Can anyone tell me what is wrong?
I did both a soft reset and a hard reset to no avail. PLEASE someone help!!

Airport Connects but has Self-Assigned IP address and no internet

All right Apple this is some Bull#@$% I own 3 Apple units One is a MacBook Pro, one is a Macbook and the other is a G5 Dual processor tower. The MacBook and Tower are using OS X 10.5.5 and the MacBook Pro has OS X 10.4.11. Ok here is my problem all of a sudden all 3 units that had been connecting to the same wireless router for the past year started saying (AirPort has a self-assigned IP address and may not be able to connect to the internet) Apple Care suggested replacing the router well I did that and hello I have the same message. Its connecting but not going to the internet. Under network status I have green lights for Airport and Airport settings a yellow light for network settings and red lights for ISP, Internet and Server. I have this problem with both MacBooks both at the library, my friends house and my neighbors house thats 4 different wireless networks that do the same dang thing. I need help!!

I have also encountered this problem and I have been researching it all over the internet all evening and trying everything I could find a suggestion for. Here's what I have: Two G4 Powerbooks, one is a 550MHz 15" Powerbook, the other is a 1.5 GHz 17" Powerbook, they are both running 10.4.11 with all the updates that Software Update has to offer, the 17" is connecting via built in Airport Extreme card, the 15" is connecting via Sonnets Aria Extreme PC card. I have AT&T DSL and I'm using the 2Wire modem/router they provided me with. Neither of the Powerbooks can connect wirelessly to the internet. Furthermore, they cannot even ping the wireless router. 4 days ago, both were connecting without any trouble (and had been able to reliably every day since the beginning of August when I hooked everything up). I have made no changes to my router's settings over the weekend. Nor had I made any changes to the Powerbooks' settings during that time. It just stopped working. If I wire one or both of them to the router with ethernet cables, connection works fine. My Desktop G4 which is normally wired into the router via ethernet, connects fine so I know my internet service is available.
So far, I've restarted both machines numerous times, restarted the router numerous times. Reset the WEP password. Changed the wireless security to WPA. Changed it back to WEP. Trashed the airport plist. deleted every wireless network entry in Keychain. Disabled DHCP and assigned IP numbers manually. Changed the wireless channel (I've tried 1, 6, and 11 with and without interference robustness).
I've been reading posts about this issue on half a dozen web forums (dating back to as early as June 2004). It appears to affect a variety of routers (2Wire, Netgear, Linksys), a variety of machines (Powerbooks, iBooks, MacBookPros, iMacs) a variety of OSes (10.3, 10.4, 10.5).
This thing is really getting me down. Anybody have any other ideas?

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?

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.

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?

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 169.254.233.194 and will not be able to connect to the internet

self assigned IP address and will not be able to connect to the internet. How do I fix this?

Sorry we have no info.. so description of the problem..
Are you using wireless? If so on what? Do you have a TC?
Is this a new TC and failed to setup correctly? Or you have TC or some other wireless router that has been working fine and now failed?
Plug in by ethernet? Does it now work?
Reboot the TC.. Does it now work?
Reboot the whole network.. restart in order.. modem.. router.. TC.. whatever other network equipment.. clients.
Do some clients work and others fail?
Press and hold reset on the TC. Redo the setup.. change the TC setup to fixed channels and SMB names.
We cannot give specific answers to such vague faults.

Why does my Airport Express say "self assigned IP address"? No IP address for the ethernet, and it is not connecting to my cable router any longer...

Why does my Airport Express say "self assigned IP address"? No IP address for the ethernet, and it is not connecting to my cable router any longer...

Some cable providers.....like mine, a well known company......seem to take anywhere from a few moments to sometimes up to 30 minutes to allow their equipment back at the cable company to fully reset and issue a new fresh connection.
So, it would not hurt to leave things powered down for 15-20 minutes or more when you perform the reset that John Galt suggests.
