Airport self-assigned IP shows yellow

HI I have a problem with the network because it shows my Airport self-assigned IP with a yellow button and not green like the Ethernet. I am having problems trying to connect my iPad by airport to get mail and onto the internet, my iPad is showing my iPad in the Wi-Fi networks so am I right that it looks like it's the computer that is at fault and if so any idear what to do? I have changed things on the iPad nothing works I also have tried some of the things that are mentioned in other messages but nothing helps, and this happened out of the blue, I have reset the iPad and that did not help.

The "yellow" ball or dot usually means you do not have an Internet connection, either by Wifi or Ethernet.
You mentioned something about the "computer in error". Are you trying to hook-up the iPad to the Internet thru your computer? You do know the iPad usually talks wireless to your router, right? Or are you trying to share the Airport/Internet on the computer with your iPad? DId you go into Systems Preferences/Sharing and set Internet Sharing?

Airport self assigned ip and no internet, os 10.5.8

the airport on my system 10.5.8 ( 1.25 GHz powerPC G4, 768 MB DDR SDRAM) has either a self-assigned ip or is not able to connect to my isp. if I try to get to internet the message is connection time out. the connection trough the ethernet cable works fine. my other computers have no trouble with finding and connection with internet.
re-installing the airport software for this system 10.5.8 did not help nor was there any result from consulting the network/system preferences. airport button stays yellow and airport is not connected to a network .while on the menubar my network is checked. scanning for networks using the diagnostic button from networks , shows mostly no networks and seldom any. if they show up, airport and airport settings and network settings stay red.
my airplay-network cann't be connected either ( while my laptop has no problem in doing so).
is this a software problem of system 10.5.8? is there any relief possible? any other suggestions?

Airport Self Assigned IP after Network Diagnostic Switched PPPOE

When I was at school the other day I used the network diagnostic to connect to a pppoe network and clicked the "Show pppoe in menu bar" button. When I got home I tried to find that setting again to remove it from the menu bar and ended up going to network diagnostic and telling it my home network was pppoe so I could uncheck the box. Then I switched it back to DHCP and it will no longer get an IP! It just says self-assigned IP no matter what I do.
Tried:
Setting the firewall to allow all connections
Deleting the com.apple.airport.preferences.plist file and restarting
rebooting all the network hardware
I'm convinced it was the diagnostic switch that did this, it's actually happened to me once before in the same situation.
Any suggestions?

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.

Airport self-assigned IP not connected to internet

Hi, Could someone please help with my problem - I have been hacking away at this for 2 nights with no success. I have 3 computers trying to connect to the internet using an Airport Extreme.
-AirPort Extreme is set up and not reporting any problems
-my MacBook Pro (10.6.6) is wirelessly connecting fine
-my MacBook (10.5.8) used to wirelessly connect fine, but since a reboot of the AirPort Extreme on the weekend it has not connected. AirPort is On with message "AirPort has a self-assigned IP address and may not be able to connect to the internet". There is an IP address of 169.254.122.47
-my G5 (10.5.?) is also showing a self-assigned IP when connecting wirelessly
I have rebooted modem and AirPort Extreme, changed passwords on the wireless network, updated AirPort Utility, connected via ethernet (works fine)
Getting desperate - any help much appreciated

Airport Self-Assigned IP, the wireless doesn't connect to the internet

Hello Everyone,
I have a problem with my airport shows that has a self-assigned IP address and the DCHP doesn't renew, I tried a manually IP but doesn't work neither, I saw this problem about 4 days ago, and I search here in this same sub-forum, I saw that people with Macbook Alu 13'' having exact same problem as for the iMac 27'' Ethernet or Wireless with self-assigned IP have tried everything but nothing seems to work.
I'll leave this link here, maybe someone can be helped with it, I tried but doesn't work...

Airport self-assigned IP address not able to connect to the internet

I installed airport into my eMac and have been using for over a month with no problems. Today I crashed using iWeb and had to restart with the startup button. Upon restart I couldn't get onto the internet via airport. The computer gets on via ethernet and my MacBook can still access the internet via airport. When I am trying to connect with airport I am told I am connected to my wireless network but the System Preferences>Network with Location set to Automatic, Shows Network Status as "Airport has a self-assigned IP address and may not be able to connect to the internet." I cannot for the life of me figure out how to make it not self-assign an IP address. I hope someone out there can.

Ouch I was hoping someone would have replied after I went to bed last night.
So I looked at some other posts and tried running applejack to no avail. I also removed the network from my prefered selection and reselected it to see if the WEP was the porblem, it wasn't. Then I switched to manual selection of IP and typed in 192.168.0.1 with subnet mask 255.255.255.0. This got rid of the self-assigned IP note but when I tried to use Safari it still said I wasn't connected to the internet. Ugh. Could removing and replacing my airport card fix this problem?

Airport self assigned IP not able connect to Internet

I'm trying to connect my Mac Pro WiFi for the first time and have Airport turned on. Status says Airport hasna self-assigned IP adress and will not be able tonconnect to the Internet.
Anyone know how to get Airport to connect?
Thanks,
Steven

Thanks Linc, after clicking AirPort, Status is On and the correct network is showing in Network Name. when I click Advanced under AirPort tab the network shows in Preferred Networks the network I want to use.
In the TCP/IP tab Configuration IPv4 "Using DHCP" pulldown is selected and the IPv4 Address is the same as the previous screen where it says AirPort has the self assigned IP address and won't be able to connect to the Internet. Hmmm.
What I don't understand is that use this same network without any issues on my iPad and iPhone. Just Mac Pro AirPort is having a problem.
Thanks,
Steven

Airport Self-Assigned IP Address Issue

Hello. I recently started having issues with my MacBook Pro's Airport connecting to my home wi-fi. The Airport icon shows I'm fully connected to the internet, however, when I click and open up Network Settings I'm being told that my Airport is self-assigning an IP address instead of getting one from the router. My roommate also has a MacBook Pro an their computer is having no issues with connecting to our wi-fi. My iPhone 4 is also not connecting to our wi-fi. I have read that you can manually assign the IP address which is how I'm connecting to my home's wi-fi now, but I feel that there has to be another way for this issue to be resolved so I don't have to spend 5 minutes trying to find an unused IP address every time I want to connect to the internet. If this has been covered in another thread, please let me know. Thanks in advance!

How do I get rid of airport self-assigned IP address????

I am trying to connect to a cisco router by going wireless. It is setup as a DHCP server, however, when I use the DHCP setting under network, airport settings I can not connect to the internet and the message on the network status says the the airport has a self-assigned IP address. How do i correct this situation. I have no problems connecting with ethernet connection using DHCP server. The problem is only when I try to go wireless.

The AirPort is self-assigning itself an IP address, because it either can't "see" the DHCP server or it can't recognize it.
Which Cisco router model do you have? Is it setup for standard 802.11g or b? Are you running wireless encryption: WEP or WPA?
Double-check your AirPort settings:
To setup AirPort for High-Speed Cable Internet connectivity:
System Preferences > Network > Show > Network Port Configurations
- Verify that an AirPort option exists. If it does not, click "New" to create one. - Verify that AirPort is "On" (checked)
- Verify that AirPort is at the top of the list. If it isn't, you can drag it to the top.
Systems Preferences > Network > Show > AirPort
AirPort tab
- By default, join: Automatic
TCP/IP tab
- Configure IPv4: Using DHCP
- Configure IPv6: Automatically or Off
Proxies tab
- Configure Proxies: Manually
- Select a proxy server to configure: <All proxies should be unchecked unless you specifically require a proxy for Internet access.>
- Exclude simple hostnames (unchecked)
- Bypass proxy settings for these Hosts & Domains: <leave blank>
- Use Passive FTP Mode (PASV) (checked)

Airport self-assigned IP address, no internet

We got a new router from Verizon and my Mac will not connect. Network Status gave this message: 'Airport is connected to the network xxxxxx. Airport has a self-assigned IP address and may not be able to connect to the Internet.
How do I fix this an get connected to the internet?
Thanks in advance,
Mike from Baltimore

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?

Problems connecting Airport - self assigned IP addresses

Greetings,
I upgraded to a powerbook a few months back, and everything seemed to be working well enough until today. My internet connection (using airport on my powerbook) wasn't working. Usually I just unplug my modem, reconnect, and all works fine.
Today, to my horror, airport does not reconnect as usual and I see the note
AirPort has the self-assigned IP address xxx.xxx.xx.x and will not be able to connect to the Internet.
I've tried using snow leopard cache cleaner, I've tried restarting, I've turned off my iPhone, and disconnected my old mac connected by ethernet.
My iPhone works, using the same wifi, and there are other wifi users nearby.
Not sure what else to mention, any ideas?

try to do it manual:
decide a ipv4 close to your iphone (if iphone has xxx.xxx.x.7) like x.8
next, net-mask must be 255.255.255.0 (if there is something other it's wrong)
router is seen when you open network in iphone, take this.
could be like: 192.168.1.1, if your ip starts with 192 ...
all this in network/more options

Airport - Self Assigned IP Addess and no Connectivity

I have been having trouble connecting to wireless. It had been working fine for quite some time (years) and stopped connecting yesterday, although the PCs in our house connect just fine.
In trying to diagnose the issues, I noticed the Airpot connectin says that the IP address is self-assigned and will not be able to connect to the internet. Any ideas? I tried deleting the Airport connection and re-added it, as well as deleting the System Configuration files in the Preference files (suggestions I saw in other discussions) but neither worked. Please help.
Thanks,
Amber

That only means AirPort could not lease an IP from the router. There's nothing to say why it couldn't. The problem may be with the Mac, or it may be with the router. As a first approach, try re-starting the router.

Airport self assigned ip address

My desktop is having difficulty with connectivity. If connected directly with ethernet cable from modem, no problem, but if I try to use the built-in aiport, i receive a message "a self-assigned ip address has been assigned. No network connectivity". I am beyond frustrated as this knocks out my wireless routers because I have to use the one ethernet cable I have to run directly to the desktop. Anyone with knowledge and a heart?

Just in case you are still having the problem. From the different posts in different forums looks to me that the main reason could be related to a bug in the security configuration ... I had the problem even using no security at all.
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 Self-Assigned IP problem

I have a problem where my MacBook will occasionally not connect to certain wireless networks. When this happens, the Network preferences says that the AirPort is connected with a self-assigned IP. This doesn't just happen on my computer, it happens on 2 other MacBooks and 1 MacBook Pro, and there are times when 1 computer will not connect but the other 3 will.
I have tried power cycling the AirPort, renewing the DHCP lease, flashing the PRAM, creating a new network location and usually, none of these things work.
The computers are white MacBook's with OS X 10.5.8 and a MacBook Pro with OS X 10.4.11. The router is very often inaccessible as it's someone else's network, but I don't think this is the problem as only 1 computer usually has a problem.
Any advice would be greatly appreciated!

I have also experienced this problem. Here's what I learned. After executing a "Safe" restart (holding down the shift key during restart), I restarted in normal mode and was greeted with two queries. mDNSResponder needs permission to accept incoming traffic and same thing for configd. These are functions that apparently are needed to pick up an external IP address from the DHCP service. I looked at the firewall log and saw a long list of denials corresponding to when I lost my IP address.
The messages also note that accepting these things automatically can be set in the system preferences panel. I could not figure out how to enable these specific applications - maybe someone else can help - but if you go to System preferences pane, Security, Firewall set to allow all incoming connections. This fixed my problem, however at the cost of some security.
Must be a better solution.
