Self Assigned IP address may not be able to connect to internet

I have been using my Mac laptop for several years now an connect to the internet via both the ethernet cable and wirelessly and never had any problems but today I logged on and couldnt get connected to the internet wirelessly it said Self assigned IP address may not be able to connect to the internet. I can connect via the ethernet but not wirelessly. We have two other computers in the house, one mac and one PC and they arent having any problems but my laptop is, can anyone help me, I have tried resetting PRAM if that makes sense but I can't find anything to help me or sort it out. Can anyone be of assistance, I am not technologically minded at all and usually find the mac very easy to get my head around but this has thrown me completely - if anyone can give any direction I would be greatly appreciated

Airport Self-Assigned IP and may not be able to connect problems

I have a strange problem. I can't connect to my network. It shows that I am on the network and it even asks for the password but I can get on the internet. I have a MacBook running up-to-date Leopard. The strange thing is, the computer that I am writing this post on works, which is a MacBook Pro running Leopard as well. I have even manually entered in the IP address from the MacBook Pro computer to the MacBook, which is my computer. Airport says I am connected but the internet won't work. Anyone have any ideas?

I have even manually entered in the IP address from the MacBook Pro computer to the MacBook, which is my computer.
That won't work: you can't have two computers with the same IP number. The MacBook should be set to obtain an IP number automatically ('use DHCP'), then Airport should issue it with one. At present the Macbook is failing to get one, which is why it's assigning itself an emergency number which won't allow it to do anything.

All of a sudden I started getting "Self-assigned IP address ... Can't connect to internet" message when I attempt to connect to wi-fi at home. I tried solutions posted on the net but to no avail.

It once worked when I removed it from Network preferences and attempted a relogin - but the problem resurfaced again and is not going away. I tried the "key chain access" solution - but my Wi-Fi doesn't show up in "Sytems" at all. Any help will be appreciated. It's OS 10.6.9 MacBook Air.

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.

Self assigned ip may not be able to connect?

hello. I have an ibook g4 1ghz 1gram osx10.5.5. I purchased a wifi usb adapter with antenna from hawking technologies. I have attempted dozens of times to connect to any number of wireless networks that it detects. I have established connections with a link quality of 90 percent and link quality upwards of 80 percent however despite thehigh percentages i get no data transfer whatsoever and the network settings in the network preferences tells me that the wifi usb adapter has a self assigned ip and may not be able to connect. Or it will say that it has no ip. Also. I do not have a wireless network in m.y home i am attempting to connect through other wireless networks in my apt building

Hi there:
In attempting to detect and connect to existing wireless networks in
your vicinity, there are things to consider. One of them, is, security.
Theirs may be locked, and inaccessible to your wireless hardware.
Some of those you detect may not be usable to your hardware,
since some closed systems (not accessible from outside) may
use the same wi-fi frequencies as other wi-fi hardware, but not
take you to the internet. They may be wireless local networks.
Depending on the operating system in your computer, you can
get a few good widgets for Dashboard which can help you see
and tell what kind of wi-fi (and strength, locked/unlocked, and
what channel these are using, etc) and for the sake of testing
you could then find if any are able to be visited temporarily to
see if you really do have a valid and working wi-fi setup there.
Another alternative with portable computers, is to go to a private
or public area where they offer wireless internet access; some do
for a limited time (customers) or for some duration while you are
inside their establishment; some don't allow you to be outside
their place and login. Some public libraries allow you to take a
portable computer inside and use their 'free' wi-fi system; and
of those, it is not uncommon for them to issue a password...
And these passwords change, so as to discourage outside
theft of the service or easy hacking by those who are bored.
If you had an IP address (an account of your own, to address
your equipment to go online through) this issue would be an
easier one to resolve. There are ways of resetting a wi-fi
modem, and also proper settings in the configuration to allow
accessing a wireless network. Some of the hardware you'd
use may require setup with an Ethernet cable in order to
have a base station or other setup be properly configured.
Some of the basic setup issues which sound like yours are
centered on first not finding a network to interface with; and
also in how the settings and other details are entered into it.
If you were already set up and had your own internet provider,
then full troubleshooting of the full issue would be possible.
The AirPort software and wireless configuration software in
your computer allows you to set up several different ways;
some are almost automatic, and would detect and let you
see the names of networks (even if you can't log into them.)
The most often encountered answer to an issue of your IP
self-assigned address situation, would be something along
the lines of this link's suggestion: "Self-Assigned IP address..."
http://www.ehmac.ca/mac-ipod-help-troubleshooting/59734-self-assigned-ip-address -issue.html#post619612
The Network system pref panel allows you several ways of
setting up different types of networks; among them, Ethernet,
Dial-up, AirPort, etc. The ones you want to be active can be
chosen from a list (checkbox by ones you want) and also may
be dragged into the order of likely operability; or order of use.
If you have a base station (many of which can repeat a signal)
the options change somewhat, since there is an Airport Admin
utility that can change settings on your own base station, and
to be able to reset that, when it would be available to do so,
can also make the self-assigned IP situation go away...
Your network configuration is basically not setup properly; and
some of the online searches of this issue parallel the topic link
I posted above. Check for those which do NOT follow that lead;
and try to see if another set of instructions may do the trick.
What OS version and step is your computer using now? Do you
know if the wireless card is integrated or separate, in a compart-
ment under the keyboard? If the wireless card shows in the
System Profiler and it appears active, one can hope it is working.
Another issue may be that of the internal antenna. Using an
external USB wi-fi module removes the need to have an internal
antenna, but an existing AirPort card may be giving the System
another choice from which to choose; so another user selection
from settings in the proper control panels is required in that case.
Some of those settings and what not are outlined again in this forum
link to another situation where someone couldn't get past a self-assign-
ed IP address to go online: "10.4 - AirPort Self-Assigned IP address..."
http://www.mac-forums.com/forums/showthread.php?t=55793
At this hour, I really don't remember what I did when my computer's
settings didn't want to connect by wireless. My first setup was with
wireless through my Extreme base station's dialup modem, so I could
use my iBook white G3 wireless, from a dialup internet connection.
The same base station, some years later, is still working fine with DSL.
A second one, some miles away, is on cable modem providing wi-fi.
Write back and tell me what settings you have and what you have
changed. And more about the system; also, if you've set the computer
to automatic and visited a place such as a public library's free internet.
Good luck & happy computing!

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

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?

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?
PHY Mode

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

Many ppl Not being able to connect to internet although wifi connected.

Other forums are recieving many posts a day on this issue, and as I understand it Apple are recieving alot of calls on this issue:
Description:
Connection to an encrypted wifi network seems succesfull, however when attempting to reach the internet Safari throws up an error - The server could not be contacted - or words to that effect. None of the Internet requiring Apps work although the wifi signal indicator shows signal indicating connection.
When you click on the little blue arrow to the right of the network connection you are connected to, in "Settings > Wifi" you see a self assigned IP Address starting 169.254 and a subnet mask 255.255.0.0, with possibly no DNS if you haven´t manually entered it and no gateway.
Peculiarities:
1 Problem is widespread, not tied to specific make of router or AP, also it happens to most people on more than one AP or router
2 People with this problem are assigned a 169.254 IP address, Indicating no DCHP lease of an IP address
3 Ive ran a packet capture using wireshark and Air PCAP and seen no packets for a DCHP request.... wierd.. it looks like its not even requesting an IP address..
4 Only seems to happen on networks using some kind of encryption be it WEP, WPA, etc...
5 Although theres bars in the wifi icon that indicate a connection, it cannot be connected to the network, just try and ping your device when its supposedly connected, look at the IP.. it cant be on the network.
6 Even if you manually imput the IP address, sub mask, and gateway IP it still wont work.
7 People with Iphones seem to be able to circumvent this issue or a similar issue by manually selecting the encryption method or changing the encryption method on the router.
8 Issue observerd in varied firmware versions
Possible Conclusions:
1 The Ipod is selecting the wrong kind of encryption when the enter password dialog box comes up? OR bad key negotiation between IPOD and Router.
Although scenario 1 shouldnt be the case as WPA and WPA2 have to be a certian length etc..
Note: I have tried connecting to the network by manually entering the network details and encryption under Settings > Wifi > Other and still no luck..
Questions:
Could someone with this issue confirm 1 wheather they are using WEP encryption. 2 weather it works on a non secure router or AP. 3 weather they are imputting the full HEX key or a passphrase?
I get the feeling if you use the full hex key it may work, ive seen posts around about having to make it recognise that you are using HEX by appending a $ sign to the start of the key.. although i dont know how true this is.
I have no access to the router that dosent work for me.. so cant do tests as my home one works on all encryption methods, but ive seen about 5 Routers and AP´s so far that wont work.. all using WEP..
NOTE
On one specific AP I connect with my Ipod and get no IP from DHCP so no internet, yet my colleague sitting right next to me with an iPhone gets a DHCP assigned IP and is surfing away no probs! it even automatically connects, and im very jealous..!
Anyone got any ideas?

This happened to my ipod touch recently, on my own network--it worked the night before, but not the next morning (even though I had a full wireless connection on the touch). I had to 'forget' that network and re-add it (including WEP) and then I was able to re-connect. no idea why this occured, but that did the trick. So far, I've only had to do that once...

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.

Self-assigned IP address which is not able to connect to the internet.

Okay, so my whole issue started around six or more months ago. I have a white MacBook which I have never particularly had any connectivity problems with, at least that where caused by my laptop. I constantly am on the internet at home and have never had issues with wireless connection here. I am a full time student which means I am also constantly on campus with my laptop and needing access to the internet. Even so, there I have never had any issues with connectivity.
My issue is when I go to another university campus I am unable to connect to the internet. My airport finds the network I want and connects to it but usually within a few seconds the radial bars go a light gray and have an exclamation point through them . When looking under the Airport drop down list it simply says, "Airport has a self-assigned IP address and may not be able to connect to the internet." This particular IP that is not allowing me to access the internet starts off with 169.**.*.**. I would provide the entire IP but as I am not on that campus at the moment, I can't and don't remember it fully.
I have tried SO many different things in order to find a solution but have come up empty handed every time. I've tried turning off my firewall and all of the steps that resolution includes and have also tried to resolve the issue through the creation of a new location, new network, and the use of network assistant on Airport.
I know it is not an issue of the universities wireless network because I can easily connect to the internet through my Ipod Touch without a password simply by finding the network, connecting, stating I'm a guest, and then agreeing to the terms of use. Same goes for my local campus wireless network on both my Ipod Touch and MacBook.
I am in extreme need of a resolution and would GREATLY appreciate any kind of feedback anyone can give me. If there is any other information you may need to help me out a little more accurately just let me know, I'll be happy to give you whatever I can so that I may figure this annoyance out!

By the way, totally didn't mean to categorize this under Airport for Windows. This is my first post and OBVIOUSLY a figured out a way to mess it up. My bad. :S
But again I'd appreciate any help! :]

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?

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.

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.
