Self Assigned IP address – can't figure this out. Frustrated.

This is a long post but bear with me. It proposes a challenge for the mac connoisseur. Who knows? Might be fun?
OK, here goes:
Please help. I have been trying to fix this for about 7 months. I first noticed this issue when I started traveling around the country, from hotel to hotel. While others (PC's and Mac's) had no trouble connecting to the free wifi at these hotels, I did. I kept getting "self-assigned i.p."
This was extremely frustrating. I often had to call up the i.t. guys and ask them to help me manually put in ip address, subnet mask, router (gateway), and dns. This worked much of the time but not always.
Let me also say that, sometimes it worked perfectly! I'd say about 25% of the time (at these hotels) my internet worked perfectly – just connected immediately. The other 75... "self-assigned i.p."
I just spoke to the mac "geniuses" and they told me it's not an issue with my computer at all (either hardware or software). Are you kidding me?!?! How can they explain everyone else's internet working except mine. And I'm talking like 100 or more different hotels in a 4 month period. They were trying to tell me that it was just a coincidence every time! "You'd be surprised" one guy said. Hahaha. They said that the routers aren't accepting my computer's whatever. OK, well WHY?! The router works for everyone but me. It's something wrong with my computer right?! Well no one acknowledged this.
More background info:Just had my airport card and logic board replaced. Computer came back and the sheet said "passed all hardware tests." BUT, none of my issues (I had other ones too involving battery life and not being able to access certain websites) were fixed.
I went to an apple store. They told me to do an erase and reinstall or whatever. So I did that (by dragging and dropping everything I'd saved on an external hard drive using disk utility). By the way, I also upgraded from leopard to snow leopard. So now, if I have the same issues after this I'll know both leopard and snow leopard are screwed up.... right?
OK, so I followed their instructions on deleting and reinstalling to a tee and guess what?! Everything worked! Or so it seemed. Battery fine. Websites now accessible. I figured the airport issue was fixed too. But now that I'm not touring anymore and the airport works in my house, I never encountered any issues. Until now. At my work.
I got a new job and it's one in which I HAVE to have a computer that connects to the internet. So of course, the same issue with self assigned i.p. presents itself. Everyone else in the office has no problem. Including a Mac person that used to work there.
I've been reading some other threads that are just completely confusing me. One of them might be the solution but I thought I'd detail my troubles so that some smart computer person out there can diagnose my specific problem and give me a specific fix.
I noticed that many people believe there was a bug in one of the 10.5 updates. I am pretty quick to install updates (maybe I shouldn't be because I hear that the first updates are often buggy and maybe you should wait for a while). But this problem has continued now with Snow Leopard too so... I don't know. I don't know anything anymore. I have tried everything. And Apple is telling me it's not a problem with my computer. Give me a break.
One more interesting quirk: before doing the erase and reinstall my computer could not find the Apple Store's network. After the erase and reinstall it works. That's why I assumed everything was fine! But no. And now the Mac people are saying there's no problem because they can't see it.
BTW, I have tried all the obvious things. It's not an obvious thing. But I mean, if you think it is... then tell me I guess. But I've been in the advanced tab thousands of times. I feel like I've exhausted everything in there.
Thank you thank you thank you in advance if someone is actually able to solve my issue.

Can't figure this out- cable connection vs wifi connection

Can't figure this out: when my 13" MBP is connected wirelessly to my Airport base station, my iPad can see it. When I connect the MBP to the base station via ethernet cable (for faster connection), the iPad can no longer see it.
Note: my airport is not connected to the internet. I'm simply wanting to setup a closed network for the iPad to connect to the MBP. There's nothing else on the network. The app on the iPad is locating the MBP by ip address so it must be a permanently assigned number.

Am having the same problem.
Everything was working fine until yesterday.
Now if I connect my iMac to the Extreme with Ethernet the Airport is not visible and I can't connect to the internet.
iPods and iPhones can still use the wifi to get on the internet.
If I switch the iMac to Airport it works, but, will not work with the Ethernet cable connected.
Have tried changing ethernet cables and still no go.

How can I figure this out?

Very simple function, but as a beginner, it's still difficult for me.
my mouse wants to detect boxes on the canvas and return the center coordinate of these boxes, how can i figure this out? The game will be, if point(x,y) is inside a box , return box Center

I just noticed that you are placing them on Canvas and it is not a container object. One solution would be to keep track of boundaries of those clickable areas and whenever a click occurs, a check which box was clicked, if any. I hope this helped.

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 ...

Self-Assigned IP: How Can I Fix This?

Hi,
I've posted on this issue before, but am still having trouble. All was working well with my wireless network until recently, when I became unable to connect my iBook G4 to my wireless network via a Netgear router. I am getting the "Self-Assigned IP Address", despite the fact that I am using DHCP, have renewed the DHCP lease, and input my IP address manually. I can see my IP addresses under the DNS tab, and it is configured using DHCP with an IPv4 169. address.
I've tried all solutions. I was once able to resolve the problem by dragging the Library/Preferences/System Configuration folder onto the desktop. Now the problem has returned despite the folder being on the desktop and remains even if I move this folder back into the Preferences.
Can anyone help me? I am at the point of simply buying a new laptop, but surely there has to be a solution...
Thanks.

Ps. I am using an iMac running Snow Leopard as well. The iBook is running Panther. The desktop, so far, touch wood remains OK.

I've tried all solutions. I was once able to resolve the problem by dragging the Library/Preferences/System Configuration folder onto the desktop. Now the problem has returned despite the folder being on the desktop and remains even if I move this folder back into the Preferences.
Can anyone help me? I am at the point of simply buying a new laptop, but surely there has to be a solution...
see if the posts by Tesserax in this thread http://discussions.apple.com/thread.jspa?messageID=10162935&#10162935 give you any pointers
good luck !

Airport: Self-assigned ip address, can't connect (public routers only)

this has been talkeda bout before, but is extremely frustrating, because i don't have the problem with a PC.
1/2 of the public routers i connect to have some kind of login page, most the time they just say "youre getting free internet, click here" ... but sometimes that login page never comes up, and the network card says "airport has a self-assigned ip address and may not be able to connect to the internet"
this only happens on pulic routers for me, and only ones that have login pages.
its very odd because for example, starbucks has all the same routers, all are "attwifi" now .. i go to one, i get hte login screen, go to a different one, i don't get it...and can't connect
with a PC, i get it every time.
this is undoubtably a leopard problem, that needs to be fixed. please!

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 address, can't connect

In a few instances, I will join a network, be shown as linked to the network. Then when I look at the network status page, it reads "you are connected to the internet, however the provider has a self-assigned IP address & you may not be able to link up". Can anyone explain what to do in this situation.
Much love & thanks,
Jackson

Is the network not working at this point? What method of IP address assignement is currently selected?

Airport and a self-assigned IP address - can't access wireless net

I have a strange issue with Airport picking up a wireless network.
I'm not in my usual location using my MacBook Pro.
There is a wireless network here.
Airport sees it, and asks for the password (provided to me).
Airport looks connected, but, I see the message: "Airport has a self-assigned IP Address and may not be able to connect to the internet".
And in fact, it cannot. I've run through the diagnostics routine twice, and no go.
How do I get Airport to accept an IP address from this wireless configuration?

I am having a nearly identical problem. The solution provided did not work for me.
We have two MacBook laptops, one is mine and the other my wife's. My laptop still works fine. The AirPort communicates well with the wireless router. My wife's laptop just started having this problem about a week ago. The latest Airport software updates helped, but did not solve.
The problem is that I now have to go into network diagnostics everytime to connect my wife's laptop to the wireless router. I have to re-enter the password to the router each time. Once I enter the password, it finds the IP address and connects everything properly. I checked the keychain password and it is there, so I don't know why it keeps losing the IP address.
One thing that I did preceded this problem. I changed my router password to WEP. If anyone knows if this could cause the problem, let me know.

Self-assigned ip address -- can't connect to Airport

I have a 2006 MacBook Pro which recently started exhibiting the exact same behaviour as reported by another poster in 2011:
For some reason the computer has started self-asigning its IP address and Network Preferences says that, because of the self-assigned IP, i cannot connect to the network.
I have two other Macs connecting to the same Air Port with no issues and I've tried to duplicate those settings on the MacBook Pro but still get the "self-assigned ip" message
Tried re-setting SMC and PRAM, no change.
The only change to my wireless setup was the change from a Verizon-owned modem to an owned Motorola unit (but the MacBook Pro connected successfully, many times, after the change).
I didn't knowingly change anything on the MacBook Pro -- from one day to the next it just stopped connecting.
I'm really at a loss to understand what's going on and, of course, not happy that the MacBook Pro can't connect to my network anymore! Help!

WHY!!!!! I can't figure this out

Why my girlfriend is getting the message that her "remote IP address is invalid" I can't seem to understand or figure this out...

They should turn off Internet Sharing in System Preferences > Sharing if it is On
Are either of you running Internet Sharing? If so, turn it off.
They should not be letting Parallels connect using the Mac's IP if they run Parallels.
Do either of you use Parallels Desktop or VMWare Fusion to run windows on you Mac? If so, turn off their access to the internet in their settings or preferences.
They should not be connected to the Router via wireless (Airport card) and Wired (Ethernet) at the same time.
Are either of you connected to both Ethernet port and Airport wireless at the same time. If so, disable one of the network configurations. Either unplug the cable or turn Airport off.
They should not have two DHCP servers in a modem and router on their LAN.
How are your router and modem configured. If they are both distributing IP addresses, then you need to either set your router to bridge mode or set the modem to assign just one IP address. I don't know what hardware you have, so I can't begin to tell you how to configure either. Unless it is an Airport Base Station, most modems and routers are configured through a Web interface. Airport Utility will let you configure the Airport Base Station.

HT201364 wow - can't figure this out -

I can't figure out how to tell what operating system I'm using and in the downloads it tells me to download OS X Mavericks and then it gives me a system error Very frustrated

You can find out what OS you are using by clicking on the apple icon in the top left corner of your screen and clicking about this mac. you can then use the version number to find out what operating system you are using.
Version 10.5 Leopard
Version 10.6 Snow Leopard
Version 10.7 Lion
Version 10.8 Mountain lion
Version 10.9 Mavericks

I have a report from WhatisHang which (in theory) tells my why my firefox constantly hangs up. But I need someone who can help figure this out.

I hope this section will work, i couldnt find a place for Hang ups, and this problem doesnt usually cause a full crash, which is why it was hard to figure it out.
I finally used the program WhatisHang to try to get an idea of what is causing the seemingly random hanging, but have been unable to find anyone who can help me with it.
I have posted the Troubleshooting Information, though i dont think it would be of much help.
I have the report available but dont know where i can post it.

I must admit I seem possibly to be suffering from hangs also, although as I am often not in a hurry when using firefox on this machine it has little impact. I am using a legacy computer and tend to blame this on the computer or maybe background tasks such as from security software or indexing.
'''Do you still get the hangs in safe mode with all''' (or maybe all but one essential plugin if you think a plugin is involved in the hangs) '''plugins disabled ?
Have you tried to rule out
* background tasks are the problem, (at least monitor what else is running using Task Manager or sysinternals process explorer)
* [[is my firefox problem a result of malware|malware]]. ( consider full system scans with multiple tools/software)
* any other interacting programs or plugins (some may not be listed in firefox, you may need to check / uninstall from the OS {Windows Control Panel})
**it may also be an idea to check hangs still occur when WhatIsHangs is not in use.
* have you tried logging the cc & gc times in the error console, (if for instance you see times in 1000s of milliseconds appearing you may have then identified one reason for firefox being unresponsive, even if the cause is not yet identified. - a symptom the memshrink firefox developers will no doubt be eager to investigate)
* if you can get hangs in safe mode, on at least the Aurora channel releases I suggest you immediately go ahead and file a bug yourself. (I will try to find time if not today then next weekend to look more closely at my own system to see if it is showing hangs in firefox use)
** ideally try with all default preferences
** As you have changed preferences, I suggest you include as a attachment in the bug your list of user modified preferences (use ''about:support'' or Troubleshooting Information option)
** State what security software is in use, it could be an important factor. (I imagine the majority of users have security software, or if not have security vulnerabilities and potentially an undetected malware problem)
I will try to find and download a copy of WhatIsHang, see if it works on my system and what results it then shows.
I realise I have not said anything terribly helpful I solving your problem, but I suspect you are not alone in having hangs, if you are able to spare the time to investigate and report I am sure it will help others.
Firefox has had a few problems recently that would have been solved sooner if they were investigated when first reported, but unfortunatly an advantage of firefox is how easy it is to customise, but the downside is differentiating between a firefox fault and customisation problems.

I can't figure this out for some reason.

I want to use a template in DVD studio pro and have the button text fade in at a certain point and have it be highlitghed when it is selected. It seems like it should be a simple thing but I can't figure out how to do it.
Thank You
Vincent LeGrow

You would need to animate the background then bring the overlay in (fade in fade outs as part of movie.)
Take a look here for how to do it (this example uses some items from DVD SP templates but would work otherwise, you can skip down to step 8 or so)
