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 ...

"ethernet has a self assigned IP address and will not connect to the internet" - how do i fix this?

A message saying "ethernet has a self assigned IP address and will not connect to the internet" comes up whenever I plug the cable in. Everyone's computers work except for mine work in the house and I have tried different cords and connecting sites.
Please help

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

Ethernet has a self-assigned IP address and will not be able to connect to the internet
The problem appears to have been a connection error as well as the system preferences which have reset with a 'valid' IP address after a system preferences 'reboot'.

Power off your internet router. Disconnect completely from its mains power by pulling the plug out of the mains socket. Disconnect all ethernet leads and cables to the router. Wait a minute or so and then reconnect all cables and turn on the power. See if your internet starts.

"Airport has a self assigned IP address & cannot connect to internet"

Hi, I'd appreciate any insight at all on this...
Apologies in advance for this vast post...!
(but I guess I may as well mention everything I've already tried...)
BACKGROUND:
I was recently trying to add an Airport Express Base Station to an existing ethernet and wireless network, which has been working flawlessly for 3 years.
(Network consists of an ethernet-connected G4 Dual 1.42 desktop running OS X.3.3, and two wireless-connected iBooks- one a 12" running OS X.3.5, the other a 14" on OS X.4.2).
For various reasons, I've now given up with the Airport Express, but ...
PROBLEM:
On the wireless 12" iBook- "Safari can't open the page "xxx" because it can't find the server "xxx"- ie, the internet connection is now wonky.(The problem is the same in Firefox, IE, and Camino too).
The fault must be with configuration on this laptop, as the other two machines on this network are still running and connecting normally with no problems at all.
What is the cause of this problem? (IP addresses? DNS server?)
WHAT I'VE TRIED SO FAR:
1. First looked at System Preferences --> Network --> Network Status, where I see this;
"Airport is connected to the network "Fritz!Box SL WLAN". Airport has a self-assigned IP address and may not be able to connect to the Internet."
Alongside it an amber button (which is usually green).
Then according to JohnHuber1's suggestion in Discussions on May 3rd 2006;
"Go to System Preferences --> Network and double click on Airport to open its preferences. Click on theTCP/IP tab and select Configure IvP4: "Using DHCP" and click on Apply Changes to save it."
I tried toggling this (it was already set this way), and then Restarted, but it hasn't helped.
I also tried clicking the 'Renew DHCP lease' button. Also hasn't helped.
2. Repaired permissions. It hasn't helped.
3. Read Apple KB article No:106798- 'Troubleshooting "Server could not be found" messages'.
From this article, it seems that
a) The problem cannot be caused by "an actual loss of internet connection", as the other 2 machines are still connecting fine.
b) Typing http://17.254.0.91 instead of http://www.apple.com makes no difference, therefore it doesn't APPEAR to be a DNS server problem. (?)
4. Tried to reconfigure the Airport settings using Network SetUp Assistant.
This allows me to select Airport as my connection method, select the network from the list; but once I've entered the network password and pressed 'continue', it then gives me a dialogue box, saying
"Unable to establish a network connection. Your computer could not connect to the internet. Click OK to go back and change your network settings and try again".
Returning to Network Prefs, I now see a box saying "Your Network Settings have been changed by another application".
I can't seem to get out of that vicious circle.
5. Opened a fresh Test Account, behaviour is the same here as in the regular user account.
6. Opened Network Utility, tried to 'Ping' on 17.254.0.91 (Apple site). Then tried to Ping my network router (192.168.178.1), and then also the other 2 computers on the network. Result in each case was "10 packets transmitted, 0 packets received, 100% packet loss".
What can I do to fix this problem? I suspect it's some small configuration checkbox in Network preferences which I've inadvertently altered.
But have I got any idea what I've done...?
Sorry for the epic post. But you get the idea...!
Thanks for your thoughts...
G4 Dual 1.42, FW800, 2GB RAM, (OSX.3.3), iBook G4 (1.2ghz, 1GB RAM, OSX.3.5) Mac OS X (10.3.3) 3 int.HDs, 3 Lacie ext.HDs, Logic Pro 6.4, RME Fireface 800.

Hi Grant, thanks for jumping in...
Have you removed the troublesome Airport Express?
Certainly have, that was Step 1 several days ago!
Are you using encryption?
Yes, I have to enter a password every time I've tried to use Network Set Up Assistant. I'm pretty sure I've got it right- it won't accept anything else.
Have you limited your network to only certain M.A.C. Addresses?
Not as far as I'm aware. Could I have done it inadvertently?
Is the Wireless Router set to allow the connection of slower 802.11b devices like the iBook?
Guess it must be... it worked fine before, and is still ok with the other 14" iBook.
Are you connecting to a Wireless Router and not to another Macintosh computer?
Hmm... I ASSUMED I was connecting to the WLAN router. The G4 desktop has no wireless capability itself, could I still be connecting to that regardless?
Internet access has never been affected in the past by that machine being on or off...
You will not be able to get anywhere until you have an IP address in the same subnet as your Router
(generally high octets the same, last octet different). Can you think of any reason why your Router
should not give you an IP address in this range?
Err... now I'm lost, sorry! What's an octet?
I really appreciate you taking the time to help me out Grant... sorry I'm not really up to speed!
Cheers, Andy.

Connectivity Issue: "Airport has a self-assigned ip address..."

I've been using the same wireless network via AT&T with their own wireless modem/router that they provided for the past six months. Never had an issue EVER. Now....suddenly, it says "Airport has a self-assigned ip address and may not be able to connect to the internet."
OK. I jumped on my girlfriends IBM, it and all the other PC computers in our house work FINE. I can also directly connect to the router via an ethernet cable and connect FINE.
So I open up the router settings in my browser and notice that the IP address the router says my computer has is 192.168.1.100. This is not the IP address my network settings displays when I get a DHCP lease. So... I select "manually" instead of "automatically via DHCP" and type in the IP address the router seems to think my computer is. Now in the "show network status window" it says that "Airport is connected to the network" but I still can't connect to the internet.
This is driving me completely bat **** crazy. Nothing has been changed in the wireless settings on my computer, any other computer in the house, or the router itself. This seems to have happened randomly, after searching all over the internet I can't find any solution that works for me. anyone know what's up?

As you may have gathered, this message appears when the computer has failed to obtain an IP number from the router using DHCP, so it self-assigns a fallback number which, since the router doesn't know it, prevents connection to the internet.
The obvious first step is to turn everything off, and then boot the router and each of the computers, one at a time, so that each should get a new DHCP lease. All the IP numbers should be issued and obtained automatically.
This thread offers some solutions, some of which have worked for some posters:

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router (Auto is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

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.

ERROR: Wi-Fi has the self-assigned IP address

I'm having an issue with both my MacBook Pros at my home. If I try to connect to the Time Capsule after coming home from work, I receive the exclamation point in my wifi status icon and this error message in my network preferences pane:
"Wi-Fi has the self-assigned IP address 169.254.121.202 and will not be able to connect to the Internet."
The IP address is always different, but it always gives me a subnet mask of 255.255.0.0 and no Router IP.
This problem only seems to occur when both Macs are connecting and not connecting to the Time Capsule wifi. That is, when my girlfriend is out of town with her MBP gone, I never seem to have the issue.
It also seems like the first of our two to connect is the "winner" and will connect just fine, but the second one will not. If both computers are open and waiting to connect while we power cycle the Time Capsule, it will connect without any problem. If I then leave for work, come back home, try to connect, we have to start the same song and dance all over again.
I've tried just renewing the IP. I've tried restoring the factory settings on the Time Capsule.
I have a sneaking suspicion this may have something to do with the problem: My MBP is a 3rd generation copy of the data from hers. Hers was once my MBP, but we copied everything from it to a new MBP, which later was copied to a third MBP (the one I'm using now).
Thanks for any help anyone can provide!

That is interesting idea.. although the MAC address will be different I wonder if something in the GUID of the install being identical could cause issues..
Do both laptops have the same wireless cards?? Different models came with different cards. .these can not cooperate very well.. although I have seldom heard of them fighting in quite that way.
If you want to take the trouble.. a replacement hard drive and a new install of the OS.. see if it still happens.. how hard do you want to pursue it.
Check the log in the TC for when you try to connect.. and see if there is a reason given for not accepting you. Did you change the laptop network name.. ie they don't both have the same name do they.. it would not work if that was the case.

HT4628 My Mac Air OSX10.8.5 won't connect to the internet as it says it has a self assigned IP address and thus cannot connect to the internet. I can only connect to a network by manually typing in the configuration specs. Please help.

My mac air OSX10.8.5 won't connect to the internet. It says it has a 'self assigned IP address and therefore cannot connect to the internet'. Network diagnostics is unable to the solve the problem. It happened suddenly for no reason and now I cannot connect except by typing in the configuration settings manually. Please help me!

Use the Airport Utility or log into your wireless device via http and ensure the DHCP/NAT service is enabled. If accessing via HTTP, you will need to manually set an ip within your local subnet (eg: 192.168.0.x).

Cannot connect to internet as Airport "has a self assigned IP address"?

I suddenly cannot connet to wireless internet as the Airport has a "self assigned IP address" whatever that is. I have tried removing other wireless connectons but it makes no difference. I'm trying to use the wireless connection at the hotel I'm stying in..its working fine on this computer. Any suggestions ...PLEASE?
Thanks

Hmmm... well, not what I was hoping to find b/c that is not really a helpful answer, l.b, but thanks for joining in on the discussion. I too just experienced the same problem. Yesterday I was connected just fine, a little slow, but connecting just the same. I was able to do my banking, browsing & what have ya. Today I get up and have no internet connection and my computer says it Airport has self-assigned an ip address and I cannot connect to the Internet. I haven't done anything different and as I can tell, they haven't done anything different either. My iMAC will not connect, but this piece of poop del mini will as will my iphone4 and all three of my kids' ipod touches. Soooo.... anyone else have a solution b/c I am totally at a loss here. I really need my iMac to connect. Got things to do that I can't do on here.

MY imac has a self assigned IP address

I cant use my imac coz it has a self assigned IP address and wifi not be able to connect to internet. We actually change to fiber net. when fiber net was installed in our home that's the beginning of my wifi problem. The sad thing is only my Imac got the prob. the rest of the computers at home got signal. They said fiber network makes your surfing to internet even faster but its not what I expected. one imac and one mac book pro are functioning using wifi but slower than before .The only Imac which I am using is the only one that cant be used. any suggestions from u. I tried everything. unplugged, turn off routers, rebooth imac, rebooth routers. but it still the same the IP address is self assigned.

Hello, try this...
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.
Instead of joining it from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.

I getting airport has a self-assigned ip address and may not be able to connect to the internet

I have got exactly the same message after we re-configured our router. I was connecting using my iMac wirelessly before hand, but now cannot. Our other PCs can connect wirelessly to the router so it's not the router. I have also tried the firewall solution but that doesn't work either.
I did call Apple Support who said that a full troubleshoot would cost £35 as my computer is older than 90 days (well yes it's been working fine that's why it's over 90 days old, it's only now that it isn't!). He said a trouble shoot didn't guarantee success so I declined his offer to charge me an extortionate amount of money for nothing! He did say that the router needs to be giving the Airport an IP address, but it isn't doing it now. His only suggestion was to turn off the router and turn it back on or power down the iMac. Neither of which help.
Anyone else had any success?

Hello:
I am a long way from a wi-fi expert, but.....
You need, I think, either a router with wi-fi or an airport (express or extreme). The iPad needs to connect to to a network. In my case, I use an airport express and both my iMac and iPad 2 connect to the Internet through the airport device.
