Airport has a self assigned IP and can't connect to the internet

Thats what i get when i want to share an internet connection from my mini, macbook and macbook pro.
none of them give an internet signal out to the world, they used to, but i think the last software update changed things.
so, being that i have the same problem with 3 machines i can say for sure its not a hardware problem, tried manually assigning an ip address, changing the network channel to any of the options.
still im giving no internet to any device. Running snow leopard 10.6.5 on c2d intel machines.
please, help me, as im getting heavy complaints from other people who havent got internet access for days thanks to this.
thanks
ps: i have no router. i just have one mac connected via ethernet to the internet, and i want that machine to share internet via airport / wifi to other devices such as a macbook or an ipod touch
this worked wonders for a while, then stopped working, then worked again, then stopped. it seems it comes and goes as macOSX updates come and go.

Is your computer which is acting as your gateway for the rest of your network running its firewall and blocking the traffic from the other computers? Can your other computers connect to each other? Ping each other?

What to do if you can't access a wifi network and showing you message that your airport has a self-assigned IP and cannot be connected to the internet?

Hi,
i am currently using 10.6.8 snow leopard
i usually access internet through my broadband modem and wifi at home.
i've been using our home wifi network for almost 1 week now (since it's new) and almost everyone at home use it as well.
and im using my broadband everytime i go out.
this last week, i went to a vacation and i use the wifi connection of the hotel where i stay in.
my connection works fine and so i don't use my broadband anymore.
then i got home..
when i got home.. i tried to connect to our home wifi network again .
like what im doing before, im clicking the airport icon on the top of my desktop,
and since my airport is always on, the next step that im doing is to click the preferred network that i want to join and put the password on it.
this is perfectly working in my macbook before i left.
but now , it's not working to my laptop anymore! i can't connect to it!
after putting the password and hitting the enter, the airport icon at the top will run, however after seconds it showing gray color with exclamation point on it!
the alert is showing : No internet connection
but the network i joined is still checked and showing full signal !
i tried checking my Network under system preferrence and the airport tab in the left corner is showing me a message that
my airport has the self-assigned IP address 169.***.****.** and will not be able to connect to internet!
i don't know what happen and i dont understand why is this happening since everyone at home can still use and access our home wifi !!
it's the same network that i'm trying to connect to anyway!
i tried using my broadband instead to connect online and it works fine!
but everytime i try to connect using wifi at home , again i cant connect!
anyone can tell me what's going on?
i haven't try joining other network anyway! but i'm planning to do so..
can some one help me please??
showing me a message that
my airport has the self-assigned IP address 169.***.****.** and will not be able to connect to internet!

and now, when i tried to check again my network preference below the airport tab is showing a message that
"my airport does not have an IP address and cannot connect to the internet!"
then after seconds it will goes back to the first message that
"airport has the self assigned IP address etc....."
i don't know whats going on now!
airport tab is not showing green color anyway! i'ts always in yellow!
i tried turning it on and off but nothing happen! HEEELLLLPP!!!!

My airport says self-assigned ip and won't connect to the wireless internet.

My airport says self-assigned ip and won't connect to the internet. It's set on Using DHCP, and nothing has changed router/internet wise. I tried it with the firewall off as well, but it still doesn't work. The ethernet works, and I tried setting the ip address manually to the same one as the router. It said it connected, but when I tried to load pages, etc. safari said I was not connected to the internet.
I also tried doing system updates and updating the airport utility - still nothing.

Try changing the channel in use in case you're getting interference.
If you have WEP enabled on the Internet Sharing it'ss worth disabling it whilst troubleshooting the connectivity issues.

Just bought a macbook and can't connect to the internet. very frustrating

i can't connect through my wireless router. it reads it but can't connect. my brothers hp laptop connects to it and works. i brought it to work and tried to connect to the router at work but it failed again. but my bro's hp just reads it right away. i need some help please.

Hi,
The same happened to me, but here's a fix.
If it is password encrypted, when you first turn on your macbook, and they give you the internet connection list, Click on advance, and select "This computer does not connect to the internet" Then everything will finish installing.
Now when you see the wireless symbol on top of your screen (right next to the blue tooth) select Airport ON if it isn't enabled. Then connect to your wireless router, and when it asks for the password, click on the internet password type, and select the "Wireless WEP 12/48 key...or something like that" and it should connect. That is what I did to my macbook and it worked

I have windows on my mac and lost audio and can't connect to the internet.anyone else having this problem? Or have it installed at the apple store?

I have windows on my mac which was installed at the apple store. I have lost audio and cannot connect to the internet on the windows side. Mac is ok. apple genius and tech support can't help me and say I need to go to microsoft. In fact the tech support was unaware that windows was loaded on by the apple retail store. Has anyone else had this problem?I recently bought fusion thinking this would help bridge between the two( as told by the genius bar) but it didn't help.Any ideas?

hey mate i used to have the same problem and i got computers maintenance guys out to fix it in the end and all it was, was the router.. got a new one and it was all good after that! i think some routers just arent compatible for some reason or another.

I suddenly don't have an IP address and can't connect to the Internet!

A friend came over about a week ago and started playing with my MacBook pro. For most of the week I kept dropping the wifi signal. Then yesterday it wouldn't connect anymore. I tried restarting it several times, and renewing the DHCP lease, and removing all the remembered networks. Tried running the assistant and diagnostics, with no help. It says I don't have an IP address and that's why I can't connect. Any help?

Self assigned ip and can't connect wirelessly on any apple device

Man oh man... this issue has been festering for almost an entire year now and I have not found a solution. Last August (2009) my macbook stopped wirelessly connecting to my ATT 2WIRE dsl modem saying it had a self assigned ip address. I bought the computer in July and could connect with no issues for about a month. Ever since then, I've been connected via ethernet with slow connection. At the same time, the 2 iPhones in our household also could not connect wirelessly. One G5 could connect wirelessly but was extremely weak and often dropped the signal.
I did tons of research and found zillions of other people with this issue and no resolution. I've tried every solution on macrumors, and apple discussions with no results... I've disabled firewall, renewed DHCP, tried DHCP manual (which then changes the status to say I'm connected, but nothing works in my browser), restarted, etc. At work, I can connect to our Linksys router wirelessly with no issues. When my friends come over, their macbooks and iPhones don't work either!
Originally I thought the issue was my modem so I ordered another one. Same issue. Just this week I was at my wits end and cancelled my service with ATT and switched to Clear. I acquired a Linksys router to connect to the Clear Modem and I'm STILL having this issue. The difference is now that my iPhone can connect wirelessly but my macbook still cannot. The router is a Linksys WRT51ab. My macbook pro is on version 10.5.8. I can only assume that some kind of update to airport is causing the problem. As of now, my IPv4 address is: 169.254.111.225
Please someone help me! I promise some kind of reward if you can help me fix this.

Based on the model number, your Linksys router is OLD.
I'd actually suspect that your router has been the problem.
You can download the full user manual here --> http://homedownloads.cisco.com/downloads/wrt51ab_ug.pdf
I don't know if you ever secured your wireless router or renamed it from the factory defaults.
If it your Linksys wireless router is not password secured, it's possible that someone else changed settings about the time things stopped connecting.
Regardless, you can completely reset the Linksys to the factory defaults by holding down the Reset button on the Linksys for more than 10 seconds.
Do that first.
Then see if things 'magically' start connecting again. I'm guessing the phones will connect, but the Mac still won't, because of the IP address in the current configuration.
If not, here's how to configure your Mac network settings.
On your Mac, in System Preferences, Internet and Network, Network,
Click on Location, Edit Location
Click the + sign to create a new location called '_test'
(The underscore before the name will put it at the top of your Locations list where it's easy to find)
Select Ethernet (wired)
First, we'll let DHCP try to set the address.
Click Apply.
Move the selection back to Ethernet, and watch the Status.
If it shows Connected and IP address appears after a few moments, at least the WIRED configuration is working.
Now IF the Wired configuration works, lets move on to the wireless configuration...
(If the Wired configuration is still not working, post back and we'll work through it.)
Still in System Preferences, Internet and Network, Network, with the _test location you just created...
Select the AirPort interface in the left column.
Turn AirPort On.
If no Network Name appears, click on the up/down button and select Join Other Network and select your Linksys router name.
Click 'Apply'.
Leave DHCP settings alone and watch the Status to see if it connects.
Let me know what happens!

Loosing Phone Signal and can't connect to the internet

HT3728 My airport shows a blinking yellow light? Can't connect to the internet.

Help

Whenever major network changes are made.. eg.
My husband switched out TV cable boxes and had to unplug something.
Then you need to reset the AE back to factory and redo the setup from scratch.. it is near impossible to fix when the network has been altered apart from that.
BTW.. what exactly did hubby unplug??
How to reset.
Unplug the power to the Extreme..
Hold in reset and keep holding it on while you plug power back in.. get hubby to help. You need 3arms to do it.
Count to 10 slowly all the while waiting for the front LED to flash rapidly.. about double the speed of the normal slow flash.. release the reset.. and wait a couple of min for the Extreme to reboot.. then run through the setup again.
If your current setup has a router, then setup in bridge. I suspect this is what it is otherwise your other stuff would not work.
If you still have trouble.. what is the modem make and model??

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.

Why (out of the blue) airport extreme can't connect to the internet?

Suddenly the airport extreme on my macbook pro (10.6.8) decided to completely stop working. the modem/router work fine as i tested them with another computer and i've brought my macbook to another house and tested it there and the same thing happens. if i'm hardwired via ethernet cable the internet works like normal. which is what i'm doing now.
the wireless icon on the top of the screen shows full strength and when i click on it it shows my network with a check mark next to it but if i try to open a browser window it won't work. opening network preferences shows that airport is not connected and it does not have an IP address and can't connect to the internet. if i open airport utility (5.6.1) it says "airport utility unable to find any airport wireless devices".
everything was working fine a few days ago.
what's going on?

The same thing happened to me, and I took it to get looked at and they even replaced my base station, but then it kept disconnecting. I finally found the answer that solved my problem, but now I can't find the post that solved it to direct you toward. So I'll try to re-create it as best as I can.
Like that user, I have Xfinity. The other user had received this assistance from Comcast tech support (Which is sad that Comcast was more helpful than ... anyone ... but especially Apple), so if it doesn't work they should be able to help fill the gaps. Chances are, you may be better off getting assistance from your ISP than from Apple.
Basically, Comcast switched over to IPv6, and it needs to be accounted for or else the AEBS will drop the signal from the DSL modem.
1. Open Airport Utility
2. Click Edit on your AEBS icon.
3. Click the Internet tab.
4. Click Internet Options.
5. Make sure IPv6 Mode is set to "Tunnel."
6. Click the "Enable IPv6 Connection Sharing" radio button so that it's active.
7. Save changes, Update the new settings, and let the AEBS restart with the new changes.
I fixed it a couple of days ago, and it's worked perfectly since then.
Here's the post that fixed it. https://discussions.apple.com/message/21916742#21916742
Here's the Comcast information the post refers to. http://www.comcast6.net/index.php/6to4config#faq3

Extreme (b/g/n) can't connect to the internet

my iMac has no problem seeing my airport extreme (b/g/n), but I can't connect to the internet.
I have tried soft / hard reset & factory reset as well, none of them worked. The extreme just keep flashing its amber light.
On my iMac, I have full signal bars, so recognizing the extreme is not a problem. The only thing I find strange is that the IP address (the one assigned by my ISP) is 0.0.0.1.
I tried connecting through an Ethernet cable and it didn't have any problem, so it's not my ISP. The only thing I can thing of is that the extreme somehow is having trouble recognizing that assigned IP and that's why I can't get connect to the internet.
Anyone suggestion? Is my extreme broken? If so, can it be fixed? Please help.

Problem solved!
Every time, I feel so stupid once I find out the answer to my problem.
Here it is from another post by 'dwbird':
"Solution: I found that the service name (optional on the setup) may be optional but if your service doesn't require it and you put a service name in the block it prevents the system from working, hence cannot find the PPoE Server and also cannot get an IP address assigned. Guess the moral of the story is that if it is not absolutely required don't fill in any "optional" blocks"
I deleted the name of my ISP and everything works just fine, the stupidest thing is that this is not the first time...
maybe Apple should consider putting a reminder/warning underneath this OPTIONAL service name field.

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.
