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.

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?

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.

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).

"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

I just upgraded to a new iMac running OS X 10.8.2 and can't scan from by Brother MHC 7820N. Printer works. I reinstalled the scanner driver but when I try to scan, the scanner doesn't connect to the imac. Image Capture says no scanner connected.

I just upgraded to a new imac running OS X 10.8.2 and am having trouble scanning from my Brother MHC 7820N. Printer works fine but the scanner won't connect to the imac. I reinstalled the scanner driver from Brother.com but no luck. When I go to Image Capture, it says no scanner connected. Any suggestions?

You might try a third party scanner software. Printer manufacturers are terrible about keeping their products updated. I'd recommend VueScan, you can get a trial version here and if it works and you like it you can purchase it.

Self assigned IP Address, wireless doesn't work

After upgrading to Leopard I keep getting "AirPort has a self-assigned IP address and may not be able to connect to the Internet." when I try to connect to the wireless network. Thus, wifi does not work at all. I've researched it best I can and it seems to be a problem with the router assigning an IP address to the mac, but why didn't this happen in Tiger? However if I play around with it for awhile it will randomly start working, but the same method doesn't fix it everytime. It also works fine in bootcamp. If I physically plug into the router, it works fine. This problem didn't exist in Tiger at all.

Follow-up:
On the two laptops, I finally managed to get on line by switching to a different wireless access point, on a different modem. I surmise that the communication between the Macbook DHCP client and the modem/router's DHCP server is less than 100% effective. Looking at the modem/router, I could see that all of the Macs had active connections. But, instead of showing the names of the Macs, the page showed a star (*) for each Mac. I had to compare Mac addresses to verify the connections. The MAC address, of course, is hard-wired into the computer's network interface. It appears that either the DHCP client didn't know what question to ask when it broadcast for an IP address, or it couldn't interpret the answer. Except in the case of the iMac, which worked perfectly.
I upgraded the MacPro last, since it is my primary machine. Same story--connection with self-assigned address, which is useless. However, this time, having nothing left to lose, I restarted the modem/router, which presumably dumped any inactive connections and issued new DHCP leases.
However, I do have a few words for the Apple GENIUSES! The Leopard network preferences page puts me in mind of a maintenance free battery. A few of the older folks will remember when you bought a car battery that had to be filled with distilled water to reconstitute the electrolyte. Then, periodically, you check the level of the liquid in the battery, and added distilled water when required. Adding water was required on occasion because some of the water would boil off under certain conditions. Then, we got the maintenance free battery, which is virtually identical to the older battery design, except that you don't have to perform the maintenance of replenishing the water. It turns out, however, that maintenance free batteries do vent on occasion, and should have water added. But, you can't add water because the battery is sealed. So, the difference between conventional and maintenance free is not that the maintenance free battery doesn't need maintenance, it is that you can't perform the maintenance without voiding the warranty.
The Leopard network preference page won't let you set the parameters that could restore a connection. If the DHCP client doesn't work automatically, you're stuck.

The mobile doesn't connect to the computer

Hello,
I installed the Edge Inspect, the extension and the app. The computer and the phone are on the same wifi network. When I try to connect with the mobile it doesn't find anything. When I try the manual connection I get this: Connection unsuccessful, please try again.
In the firewall the port 7682 is allowed.
I checked the background.html file in the chrome extensions and give this message:
WebSocket connection to 'ws://127.0.0.1:7682/' failed: Could not decode a text frame as UTF-8. inspect.js:61
Uncaught SyntaxError: Unexpected token u inspect.js:224
trying inspect.js:1209
What should I do now to get it working?

Hi,
Looks like Chrome extension is not able to connect to Edge Inspect cc app installed on desktop. What's the state of Chrome extension icon. Is it grey?
Also, are you signed in with Adobe ID in Edge Isnpect cc.

Fix for Airport Wireless Connection Problem stating Self-Assigned IP and not wanting to connect in Lion OSX.

Fix for Airport Wireless Connection Problem stating Self-Assigned IP and not wanting to connect in Lion OSX.
Bought my girlfriend the newest Macbook Pro 13" and began experiencing problems with my wifi the moment we got home. Her Macbook would not connect to our home Wi-Fi while my old Macbook Late 2008 running Snow Leopard connected without a problem. Airport would say that it had a Self-Assigned IP address (168.x.x.x). Did not realize it was a Lion problem until after using her Macbook Pro and becoming jealous of the new OSX, I upgraded. Soon after I was unable to go online. Luckily I had my iPad 2 and I began to scoure the net for help. Ran into allot of suggestions but it was not until I tried the following all together was I able to share the good new, from my Macbook. Hope this works:
First go to Preferences > Network and click on the cog next to the + and - on the sidebar and click Set Service Order
     - Move Wi-Fi to the top and click ok.
     - Set location to Automatic
     - Click Apply
     - Click Advanced
     - Click the "-" on the selected Wi-Fi router you wish to connect to
     - Click Apply
     - Click Lock to Prevent Further Changes
Go to your Mac's harddrive, (Macintosh)
     - Go to Library > Preferences > SystemConfiguration >
     - Delete "com.apple.airport.preferences.plist" file
Turn off your computer
     - push and hold Option+Command+R+P
     - turn on computer
     - when the grey screen turns on you will hear the OS X "ON" sound (for lack of a proper term) and it will momentarily restart.
     - you will once again hear the "ON" sound, let go of all keys.
     - this resets your PRAM
Go to Preferences > Network > Advanced > + sign
     - click Choose a Network
     - Select your network and enter password
Viola!!! I tried this on my Macbook Late 2008 and my girlfriends new Macbook Pro 2010

     No you are clearly mistaken. The Self-Assigned IP address problem exists on many Macbook Pro models, including the current model, which I mentioned as being the original computer with the problem. While my 2008 Macbook is older it was working perfectly on Snow Leopard and didn't suffer issues until switching to Lion. So clearly the problem exists on the operating system and not so much the hardware.
     I called Apple Support and they had no fix for the problem and told me that this would hopefully be addressed in a subsequent update. It wasn't until I came accross the answer after trying many different methods that I got both of the Macbooks to connect to my router. Otherwise I wouldn't or could not have been surfing the internet for the last 4 months.
Cheers.

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.

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.

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.
Ta

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

Hi
Basically using Snow leopard and my MACBOOK (2009) won't connect to the net. It connects to the network but I can't get on the internet.
I've seen that lots of people on the internet have had these problems with Airport.
I've tried to use DHCP renewal, and I've emptied my keychain preferences, Ive tried manual addresses.
If anyone can think of anything that would be great.
P.S both the Mac and the Wireless Router are working fine. Other computers in the house are connecting perfectly.

Try the following, in order, until (hopefully) resolved:
1a. Delete Preferred Network(s)
System Preferences > Network > AirPort > Advanced > AirPort tab
Under "Preferred Networks," delete the network(s) you regularly use from the list.
1b. Delete AirPort Keychain Entries
Launch the "Keychain Access" application located in Applications/Utilties.
Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.
1c. Add Preferred Network(s)
System Preferences > Network > AirPort > Advanced > AirPort tab
Add the preferred network(s) using the "+" button.
Restart or log out then back in.
2. Move System Configuration Files
(Note: You will have to reestablish your network connections settings.)
Go to /Library/Preferences
Move the SystemConfiguration folder to the desktop.
Restart your Mac. (Note: OS X will rebuild the files that are now sitting on your desktop. If this doesn't resolve the issue, you can move the folder back to it's original location.)

My new iMac has recently had OSX Lion installed on it and now when I start the machine it looks like its updating something every time, and the wireless doesn't work. So I restart and everything is OK - until I have to start up again the next time?

My new iMac has recently had OSX Lion installed on it and now when I start the machine it looks like its updating something every time, and the wireless doesn't work. So I restart and everything is OK - until I have to start up again the next time - then I have to repeat this again! Any help appreciated.

I've been having the same issue, but have just discovered something on my own that hasn't been pointed out in any of the forums I've visited. In what I thought would be a vain attempt to help myself, I went to System Preferences, Users & Groups, and then clicked on Login Items. I discovered that one of the Items that was listed to open automatically upon login was iTunes Helper and that there was an exclamation point beside it indicating that it was incompatible. I simply deleted that item and now I don't have the situation you described and my wireless is connected. Hope this helps!

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!
