Can't connect to internet..self assigned ip address problem with DSL Modem

I've run into this before, without resolution, and now again on a friend's iMac. Time to ask around...
Basically, everything appears to be assigned and configured perfectly, but the network status always shows, "...you have a self assigned IP address and may not be able to connect to the internet". Sure can't connect to the net when it says that.
I've gone thru the procedure advise before that details the sequence of events needed to insure the modem resets and recognizes the Mac and it's incoming DSL (sbcglobal) signal. The order of network priority is set properly by dragging built in ethernet to the top of the list. Modem was powered down, plugged in, and then connected to the Mac, but no solution. Any ideas? thanks

This continues to be a mystery. I've had my powerbook on several networks, and connection has, most of the time, been an automatic process. Additionally, I've installed new systems for people with the same isp, and all has been well. So easy is the process, it's never been an issue. However, following explicit procedural instructions (including powering the Mac down), has proven unsuccessful on 2 different occasions.
There is little help with the isp support in India, which is where the call routes too.
The only thing I have not done is to swap out the cable at one of the locations, but the other location, which has the same issue, works fine on the iMac there. Only when I connect my Powerbook to the modem, does the "...self assigned ip address...not be able to connect to the internet" appear.
I just keep thinking there has got to be a small detail that is being overlooked.

Can't get rid of self assigned IP address

Hello,
I have been trying to resolve this problem by myself for the last 4 days (by googling and reading forums) but nothing works so here I am.
I moved last Tuesday and everything worked fine until that day. Since I am in my new apartment, I can't connect to the Internet because of a self assigned IP address. Here is more info:
-I have a new modem since I moved (the apartment where I was living was furnished and had a modem already). However, I am using the same service provider and modem than the apartment I was subletting.
-I only have a modem (no router) and I use the Ethernet to connect.
-I am writing this message from a PC laptop which confirms that the modem is working fine and that the ethernet cable is fine, etc.
-I did many rounds of shutting down the computer, renew DHCP, unplugging the modem (from 1 minute to 10 hours) and plugging everything back.
-I called the ISP but they could not help (they just repeated the same instructions that I could find in the guide)...They have no idea how I can get rid of the self assigned IP address.
The problem is still the same, I can't get rid of the self assigned IP address (169.xxx).
Please help if you know other tricks to fix that issue...
Thanks a LOT in advance!!
Julie

Re 1) Setting up a new account won't solve the problem in itself but it will help narrow down the cause. The idea is this: the problem might be caused by something system-wide (e.g. a preference file in /Library/Preferences) or it might be caused by something that is specific to your account (e.g. a preference file in yourhome/Library/Preferences). If we knew which, we could target the troubleshooting appropriately. The easiest way to figure out which is to create a new user, log in as that user and see if the problem remains. If it does, it must be system-wide; if not, it is specific to your account.
Are you using any firewall software? If you are using Tiger's built-in firewall, how is it configured?

Self-assigned ip address starting with 169

Trying to connect to free wifi in paris but my gf's computer won't connect, instead it gives me a self-assigned IP address starting with 169, any thoughts on how I fix this?
Free wifi is a very big network in Paris, you only need a username and a password to sign in and can get connection almost everywhere in the city.
It works on my computer, but not on my gf's. It also works on my iphone, it's only her computer that doesn't connect. It worked on her computer aswell until yesterday evening.

Self-assigned IP Addresses 169.254.xxx.yyy are the ones your computer gives itself so that it has a name while it broadcasts a request for a better IP address. A self-assigned IP address usually persists for only a second until your Router responds with a good address. Finding yourself still stuck with a self-assigned address means you cannot reach the Router.
You should look for really fundamental problems. Is the connection method you prefer the top one in the System Preferences > Networks box? Are you too far away for a good connection? If all seems OK, use the ( Assist Me ) button in that panel and follow the Setup Assistent [not the Network diagnostics] branch to establish a good connection.

Airport Connects but has Self-Assigned IP address and no internet

All right Apple this is some Bull#@$% I own 3 Apple units One is a MacBook Pro, one is a Macbook and the other is a G5 Dual processor tower. The MacBook and Tower are using OS X 10.5.5 and the MacBook Pro has OS X 10.4.11. Ok here is my problem all of a sudden all 3 units that had been connecting to the same wireless router for the past year started saying (AirPort has a self-assigned IP address and may not be able to connect to the internet) Apple Care suggested replacing the router well I did that and hello I have the same message. Its connecting but not going to the internet. Under network status I have green lights for Airport and Airport settings a yellow light for network settings and red lights for ISP, Internet and Server. I have this problem with both MacBooks both at the library, my friends house and my neighbors house thats 4 different wireless networks that do the same dang thing. I need help!!

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?

AirPort Express won't connect because of self-assigned IP address

For years, my old AirPort Express worked just fine. Then it quit (no little lights, no action), so I bought a new one.
Now I am running into the dreaded "apple self-assigned ip address 169.254.29.74" error, which is apparently a chronic Apple thing. There's discussion all over the internet about it, and nothing seems to help.
First, the equipment:
AirPort Express
OS X 10.6.8 (Please don't tell me to upgrade because my old hardware won't support the newer OS)
Processor 2 GHz Intel Core 2 Duo. (I don't have money for a new computer and this one is working fine except for this glitch)
Memory 1 GB 667 MHz DDR2 SDRAM
Actions taken so far:
Ran the AirPort setup utility (at least ten times)
Reset the AirPort to factory specs (at least ten times)
Deleted all the old Keychain references to the old network
Deleted all the old preference files, including one for a firewall
Reset the cable modem (five or six times)
Powered down the cable modem and turned it back on (only two or three times)
Physically typed in the IP address that works for Ethernet, but got the error message that it's being used by another device (This is insane because all the other devices that could connect are physically powered down. There's only one live computer trying to connect.)
Results:
I can get a new network to show up on the AirPort icon.
The Network part of System Preferences tells me that the problem is an apple self-assigned ip address 169.254.29.74 that won't connect. ("I made this and it's useless. Aren't you proud of me?)
Questions:
The documentation says this equipment will work with Snow Leopard. Is the documentation wrong? Should I try to find a simpler wireless router that doesn't demand as much from the computer?
Perhaps the AirPort is simply broken and I should return it for a new one?
Is there some secret work-around to defeat that self-assigned IP address glitch?

I am pretty sure the Express is running in the wrong mode..
The idea to plug the computer in is to check the setup.. not to need it permanently like that.. you can use either wireless or ethernet on the new express.. the old one you could only use wireless.
Please give me a screenshot of the setup of the express.
It must be in router mode.. ie when you open the airport utility and click edit.
Then go to the network tab.. it must show DHCP and NAT.. the DHCP range does not much matter..
But I also need to see that the wan port is getting an IP correctly.

IPhone 5 and 5c can't connect to Internet every 1 or 2 days with iOS 8.0.2

After having upgraded my iPhone 5 and my wife's iPhone 5c to iOS 8.0.2, they both can't connect to Internet every 1 or 2 days.
They can't connect via wifi neither via 3G.
If I restart the devices they start to connect again.
I tried to reset the network settings and also to restore the devices from scratch via iTunes like the Apple support suggested me, but the issue still persists.
I'm very frustrated also because I bought to my wife an iPhone telling her she wouldn't have had all the issues she used to have on a previous Samsung smartphone...
Anyone has having the same issue?

After the update, try resetting your cellular network settings on the phone. Make sure the airplane setting is correct and try shutting it on and off to see if that works.
See if that helps.
Good Luck!

Self assigned IP address problem?

There are times when my Mac Pro (Lion) won't connect to my home internet and comes up with a message about a self assigned IP address. I have no idea how to solve this. At the moment I just have to keep trying to connect and sometimes hours later or the next day it will. Its very frustrating! Does anyone know what I can do / what the issue is please.

Hold down the option key and select the Wi-Fi menu in the menu bar. What values are shown for the following?
PHY Mode
Channel
Security
Signal/Noise or RSSI
Transmit Rate
Please do not post the BSSID, as that information is private.
Now hold down the option key again and select
 ▹ System Information... ▹ Network ▹ Wi-Fi
Compare the two-letter Country Code with the ISO code for your country. Does it match? The code X0 means that the country couldn't be determined. The code X3 means South America, not otherwise specified.

Airport - Self Assigned IP Address Problems

I moved into a new place recently and having problems with my Airport connection on my MacBook Pro. I get the error
"Airport the self-assigned IP Address 169.254.23.207 and will not be able to connect to the internet" (obviously the IP varies)
It's only happened ever since I moved into this new place. Comcast is our ISP and we're using a Netgear Router my step brother bought a while back. I logged into the Router and all settings seem to be normal as far as I can tell. It only happens if the computer goes to sleep or is shut off, any situation where Airport is disabled. I usually have to keep turning Airport On and Off until it comes back. I logged into the router, none of the settings seem wrong. The ISP setting is set to Dynamic IP. It's using WPA and doesn't seem to have a problem with the key.
Here's a screenie: http://img217.imageshack.us/img217/9797/screenshot20100924at502.jpg
What could be causing this problem. It's extremely frustrating.

Of course a search for "macbook and connection dropouts" results in numerous pleas for help. That is what you searched for. Did you expect your search to find the millions of users who are not having "macbook and dropout" issues?
FWIW there are many reasons why a wifi connection will "fail or dropout", one of which may be a hardware issue. But more likely is interference, configuration, firmware, router, setup, security, not reading the manual, etc.
What would lead you to believe "Apple technicians apparently are mystified."?
I doubt very much that Apple is involved in a conspiracy of silence "Given all the macs with this problem, why is Apple silent on a fix? Is this actually a hardware problem that would require the replacement of every motherboard in every mac notebook with a faulty broadcom wifi chipset? " But then I don't subscribe to many conspiracy theories.
There are many more Macs without the problem you and others here in this help forum describe than there are with the problem.

Self-assigned IPS address problem

Hi,
I have Airport Extreme on G4 with OSX 10:3.9. On open networks, (such as in a coffee shop) I get on no problem. But in some homes with wireless base stations I can't get on, no matter what we try. I keep getting the message:
"Airport has a self-assigned IP address and may not be able to connect to the Internet."
I travel a lot and this has become a real problem. I've tried everything to try and figure out how to make my Airport receive the IP address assigned to it by the base station, but with no luck. Does anyone know the secret?
Thanks so much!!!
Blake

Do you have "ask to join new networks" enabled in System Preferences / Network with the "Airport" option in the left hand pane selected, Dale? If not, try enabling it.
Is Airport the "top" option in the left hand side of the Network panel? If not, try shifting it to the top using the "Set Service order" option (available through the "rosette" next to the "+" and "-" buttons.
In the System preferences /Network panel, with Airport selected on the left, If you click on the "Advanced" button and select the TCP/IP tab, do you have "Using DHCP" selected in the IPv4 box and "Automatically" chosen in the IPv6 box?
How are you going about seeking to join the networks? (the process can vary depending on the provider)
Cheers

Self-assigned IP address problems

I'm having a problem with my wireless router connection (my Airport card shows the network, but the "fan" is greyed out, and if I choose the network it still doesn't connect - When I check network status I get "AirPort connected to network, but has self-assigned IP address and may not be able to connect...)
I can temporarily fix the problem by going into System Preferences to Network to Airport to Preferred Networks to Assist Me and THEN it will go to my network and turn on the path.
I'm running Tiger 10.4.11 on a G5 iMac with the original AirPort Extreme card, and routing through a Linksys WRT54G attached to a cable modem.
There are a lot of networks in my area, according to my wireless "fan".
If changing channels on my router might fix this, I'd like to give it a try, but I don't know how, AND I don't want to ruin the signal to the other computers in the house, which, by the way, work just fine when the iMac loses the signal.
If there's another way to tell the router to ignore the self-assigned IP address, or to get the AirPort to stop providing this ...
The problem is obviously the self-assigned IP address. The question is what is causing this?
Is it the AirPort Extreme Card?
Is it the Linksys Wireless router?
How do I test to see which it is, without losing the signal from the router to the other computers in the house?
With so many people having the same problem, there must be an answer somewhere.
Can some kind soul please point out the correct path? My tech support (teenager) will be home from college this week, and if I can prove to him that it won't ruin everything I think he'll be up to the challenge.

Hi,
Thank you Linc & dwb, I've had no issues with the router in the 14 months its been installed. But tonight I've turned off the NAS and since then no drop off for wifi/ or assigning itself an IP address.
I will switch on the NAS once again and see what happens, would it be best to assign a static IP to the NAS? One thing I have found when checking the homehub connection details, the mac air connects at the 5Gz Wireless as does the Kindle, which has also suffered from losing the wifi connection, where as my macbook pro only connects at 2.4Gz and like I said has not had any issue. Not sure if this anything to do with the problem or not?
All I do know is that since the NAS was introduced then the problems began, so again not sure if its the NAS impacting on the router or a router setting?
thanks

Self-assigned IP address problem - My solution

I am new to this board and created an ID just to write this post. When I searched for this self-assigned IP problem, I found almost 1 million results on Google so obviously I am not alone.
I have this problem off and on on the wireless network at home with a Netgear router. It has never happened at my office with a D-Link router. Never happened at Starbucks or McDonalds (yes, they all offer WiFi here). But it happened at one Pizza Hut and it also at Christchurch airport about a week ago.
Deleting one of the plist files worked once at home many months ago but this week nothing worked. My Mac usually goes back to normal by itself after I "****" it out at other WiFi networks but not this time. As a last resort, I asked my brother (our family's I.T. guy) to change the router as I had not tried that fix. He didn't do it but a day later, he gave me to oddest solution that worked in a blink of an eye.
The solution? Key in a wrong password!!!
1) Go to Keychain Access, delete the keychain for the problematic network.
2) Connect back to the network
3) Enter a WRONG password that is similar to the right one. For example, if your password is Apple123, try APPLE123. You should still connect to the network and get a self-assigned IP.
4) Repeat Step 1. To be safe, you might want to re-boot now. I did but probably didn't have to!
5) Repeat Step 2
6) Enter the right password
I'm not all that techie so all I understood from what he said was:
1) It's probably a non-Apple router bug
2) It's a hex key problem. The password wasn't being encoded/decoded properly so the router wasn't assigning the computer an IP address. Wasn't even reading the password which is why I could connect with a wrong one.
He deduced that from reading a post from a guy in Spain who thought he had carelessly entered the wrong password and was wasting the community's time with his posting. I had read that post a couple of days ago too! But obviously I thought the Spaniard had just entered the wrong password and there was no fix for me to try out. My brother is a genius!
I guess it then makes sense why fixes like:
1) Disabling the firewall
2) Deleting preference lists
3) Deleting keychains
4) Changing the router
5) Renewing DHCP lease
6) Resetting the router
...have worked for many people and not others. None of them actually fix the cause of the problem. Having searched for 3 days, I could not find the REAL reason why this happened. Personally from all I have read, I think it must be a hex key problem with Netgear and Linksys routers. I see those 2 names mentioned a **** of a lot. Maybe it's another one of those gadgets built more for PCs that don't work perfectly with Macs all the time. We used to have an Apple Airport Extreme base station but that got fried by lightning. It was not cheap.... So technically, it really isn't Apple's problem. I think if we used an Apple router, we wouldn't have a self-assigned IP address. Maybe that's why they haven't "fixed" the problem after so many years.
Anyway, let me know if my brother's fix worked for you.
This is my good deed for the weekend! Goodnight....!

Hello, thanks for the tip/post, & a warm welcome to the forums!

Mac can't connect to Internet, no IP, no DNS even with iPhone tethering

My Mac Mini Server with 10.6.8 Snow Leopard Server doesn't connect to the Internet.
It can connect to the router either via Ethernet or Airport, but it can not get an IP address -- it always assigns itself a random IP address which is not in the correct range for the router.
All other devices, including PC, iPhone and iPad can work correctly with the router.
When I manually typed in the router's IP in Safari, 192.168.0.1, I can see the router admin page. But typing in any external IP nothing shows up.
Thinking it might be the router's problem, I used iPhone 4S' tethering -- tried wifi, USB, Bluetooth tethering and the Mac Mini still doesn't have any Internet connection.
I changed the DNS in the Network preferences, trying Google's public DNS 8.8.8.8, my ISP's DNS, and empty DNS. No luck.
What steps should I take to diagnose this problem further? Coming from a Windows background I'm not sure which tools are available to solve this problem...

The answer does not vary. (See details below for why this is the case.)
Check your local DNS on the server; more likely than not, there's either an IP routing error around the gateway setting, or there's a problem with the local DNS set-up (if you're using DNS to reference the remote systems.)
Launch Terminal.app (from the Applications > Utilities folder) and issue the command
sudo changeip -checkhostname
And see whether that produces some output and indicates DNS is valid and no changes are needed, or (as I'd suspect) that there are DNS errors here and that DNS or host-level changes are needed. You'll need to specify an administrative password for the sudo command.
Also check the IP gateway setting in the server.
And (again) you need to use a static IP address for this box, within the same subnet you are using on your network. This address should be outside of the DHCP address pool(s) in use on your network.
---- more details ----
Irrespective of your usage, this box is not a desktop (client) machine. It's a server.
Server requirements do differ from clients.
Servers expect (at least for themselves) DNS services, and require a static IP address.
Servers also support more than one user, which means that server outages can effect more than one user. This detail can then lead to differences from how client boxes are typically managed. Server administrators tend to make fewer changes to and to install and reconfigure a server, and can variously make more and can make more specialized backups, than would be the case with a client box.
To use this Mac Mini Server as a client box, it's possible (per other discussions posted here in the forums) to load OS X Client onto most (all?) Mac Mini Server boxes. Caveat: I've not tried this, and I don't know off-hand if this is officially supported by Apple.
My general preference involves getting DNS services going on the local network, and to use the server for what it provides. Having DNS services on the local network can provide value, as do various other capabilities provided by OS X Server. And to treat the box like a server, with static IP and proper DNS services and related. My preference is to use a server as, well, a server, and to serve various protocols to the local clients. Because of this, servers are useful, but they're also inherently somewhat more involved to configure than are clients.

How can I connect my iPad2 WiFi (no 3G) to my wired DSL modem (not wireless capable)? is there an adapter I can connect to the modem?

Yesterday I ordered an iPad 2 WiFi version (no 3G) and I want to know if it's possible to connect it to my DSL modem that is not wifi/wireless. Is there some sort of wifi adapter I can buy to connect to the modem or do I need to buy a wireless router?
TIA

If you have a desktop that can do "Internet sharing" and wi-fi, you may be able to use that instead of buying a router. I haven't done tihs recently but played with it with my iMac before I bought a wireless router.
But a router is the better option. They're not expensive and recent ones have some decent security. I have a Netgear WGR614 (v10) with a firewall built in making me double firewalled on the desktop (where all the really critical stuff lives like banking info and all) and it has an "access control" option where you not only password your network but specify exactly which devices can connect at all. Something I like because the signal reaches the street outside the house. That's a bit more "reach" than I like. Though, funny thing, my brother (who's iPad is authorized to use my net) did a quick update by pulling into my driveway once while I wasn't even here.
Any wireless can have a surprising reach. I live in a fairly rural area and I pick up on other peoples' wireless all the time. Which, out here, I did not expect.

Can not connect to internet (self-connect or self-detect, i cant remember..

Greeting,
I've a problem regarding getting online. As the title of the subject suggested, i've to delete my AirPort account (which located together with my Bluetooth account) under "network",renew DHCP Lease, create a new account then i can online..
Any idea what's wrong with my Mac?
Any suggestion will be greatly appreciated.
Cheers.

1) When you connect windows computer to the Ethernet port of the router does it works ?
2)When you connect windows computer wirelessly to the router does it works ?
Did you tried giving Static ip address on the Mac computer.
