MacBook Pro :: No IP Address On AirPort Apparently?
Mar 28, 2012
Okay. So my Airport has decided that I apparently have no IP address. I know this is somehow my fault, and I've tried resetting it via terminal, but each time I fix it, I have internet connection for about 5 minutes and then it cuts out again. I've looked under my network settings and there's absolutely no IP address. Nothing. I set up one of the Google servers (8.8.8.8), but that is only getting me so far. I just don't know what to do next. I'm running Lion, because I know that will make a difference in how everything is set up. I have also tried to release a new one via DHCP, but that doesn't do anything when I try it.

I have a MB and MBP and they both have the same IP address, so the MBP won't work on our wireless network anymore.
How can I cahnge the IP address? We have a netgear router and are with Jersey Telecoms.

My son spilled a diet coke on my macbook. It mostly got on the keyboard and monitor. I removed the power chord, turned it off, and wiped off the soda immediately. But of course it's liquid so it is probably moved under the keys right? I turned it back on a few hours later and there doesn't seem to be any problems. Is it possible there was no damage?

I have about 60 users on my network with a router assigning DCHP leases to all machines.There is an airport extreme in bridge mode which is expanded with another airport extreme that are connecting the router to about 35 machines. There is a 50/50 mix of mac and pc.ONLY the macs are having a IP conflict issue.
Problem:IP Conflict errors only on the wireless connection throught Airport on Macbooks.I did have 1 iMac have this problem, but they are fine for the most part.It seems the MAC just will not let go of its previously issued address and is persistently re-asking the router for the address, kicking back the error.I try to have it clear the previous DCHP with no luck.
I have tried:
-Renew the DCHP lease
-Reboot Machine
-Repair Disk Permissions
-Update Software (Happens on both OSX10.6 & OSX10.7)
-Remove/Recreate Wireless Network ProfileÂ
If I just assign a manual address, it works. I don;t want to do this to everything on the network and I would love for the DCHP to work as it should on the MBPs like it does on everything else. Rebooting the router is not an option since I have an entire office on it. And.. it is probably not a router problem since the problem is concentrated on one type of machine.Â

Development of Apple's upcoming Mac OS X 10.5.5 Update appears to be winding down, with only a couple of new fixes making their way into recent builds, including one aimed at wireless issues.
This past week saw two new pre-release distributions of the 320MB Leopard update fall into developers' hands. The first arrived mid week as Mac OS X 10.5.5 build 9F25, but contained no noticeable changes from the build the preceded it.
More recently, developers were treated to build 9F29. That build tacked on a pair of fixes, one of which tackles an issue between Macs and previously joined AirPort networks, people familiar with the software say. The second fix was related to a graphics framework.
Seemingly at the tail end of its development cycle, Mac OS X 10.5.5 is reportedly hindered by a single known bug that prevents emails from being searched properly in Apple's Mail application.
The fifth maintenance and security update for Mac OS X 10.5 Leopard now stands to deliver 125 bug fixes when it's released later this month.[ View this article at AppleInsider.com ]

Well the problem started when we got a new Time Capsule (2 TB) and replaced and AEBS. At the moment we have 4 macs using the TC. Three wireless and one connected with ethernet cable. If I close the lid on my Macbook Air and open it after a few minutes, it wont connect to the internet. I get a message saying: "Airport has the self-assigned IP address (and the IP #) and will not be able to connect to the internet" I try to use the network diagnostics, and it looks like the network settings is wrong (amber light) and the internet and server is failed.
I then select the network I want to use, and then it suddenly works again. Also three of the macs are using the TC for back ups. Usually the back up gets delayed, and wont start even if I ask it to back up now. It starts to the volume ready, then it says that the disk isn't available. Is there something I cant do or is the TC faulty? My mum and dad arent too good with macs, so if they cant connect to the internet they usually just reboot and it works. I have reset the TC and created the network again, but its still the same issue.

This is an unfortunate development! It appears that one of my processors has died on me! Is this, in fact possible - and still be running? I have included a screen shot, using Temperature Monitor to show the processors and ambient temps. What other way could I determine if it truly dead? And lastly, can a replacement be had? (I'm fairly adept at computer repair) If so, where?

I have two terabyte hard drives in my desktop. Since I barely boot the desktop anymore, I pulled one out and hooked it up in a USB enclosure. I was using it to watch movies off of. I made a shortcut ("alias"?) to the drive (which was mounted using NTFS-3g) and put it in the movies folder so that I could access it from frontrow. I had a bunch of seasons of Seinfeld, Simpsons, and Family guy that i ripped from DVD using handbrake, but there was also backups of alot of my Software CD's on the drive. Nothing I can't make again from the originals, but a pain to do.
Regardless, all of a sudden (A day after hooking it up), everything is gone. On the Mac side, I just see a folder labeled "System Volume information". I unplugged it and plugged it in to windows and I just see a couple files that get created by Mac OS ("trashes", etc), none of my actual data. Both sides, however, recognize that only 27GB is free on the drive which leaves me some hope that I haven't lost everything. Does anyone have suggestions for recovering this stuff?
The drive is a WD Caviar Black 7200RPM 1TB disk. As far as I'm concerned, they are the best 1TB drive made from a warranty / reliability standpoint, but obviously disk failures do happen....this doesn't seem like a HDD failure to me though as the drive *seems* to be working correctly. I tested it with HDTune and the transfer rate is still the same, so it seems like something got corrupt somehow (not a mechanical failure)...

Recently moved and had a net connection installed yesterday, the guy set it up and it connected fine up until last night when i decided to mess around with OSC control and had to set up my own local network to do it.
Now today I'm trying to connect to the net again back on the default 'automatic' location (i made a seperate location for the OSC to try and avoid this sort of trouble) - and although Airport is picking up the router and is saying it HAS got an IP address, the internet is still not connecting.
I've done a few common sense diagnostic checks, its not Firefox becuase I'm running Little Snitch and thats not showing any movement either..I checked that its automatically configuring using DCHP and supposedly wiped the network settings by deleting the .plist files but its still doing the same thing: reporting that it's connected and has an IP address, but still with no connectivity.
Diagnostics says it 'appears to be connected' but the Network Setup Assistant gets to the last stage of the setup and asks me to check my diagnostics because it can't connect. When seconds later it has an IP and is 'connected'.

Router is a Netgear VMDG280

I have a wireless router with 2 devices connected via ethernet (PC and XBOX 360) and 3 devices connected wirelessley (Imac, macbook, iphone and printer). This morning I was using my imac and all of a sudden I got a message saying another device is using my IP address.
I tried restarting the router, the computer airport but nothing worked. The only other device on at this point was the macbook which received the same message. I assigned a manual address to the imac via the advanced settings in airport but how do I fix this so that IP addresses are assigned automatically?

About a week ago my internet connection would drop out for hours. After setting messing around with my router and modem and reseting everything it would work for a few hours then stop again. My connection is provided by Charter Cable, through a Linksys BEFCMU10 V4.0 modem, to a Linksys WRT55AG V2.0 router. If I removed the router and wired directly into the G5 from the modem, the internet connection would start working perfectly. If I went back, reset the router and hooked it up again, I would lose connection and it would actually take the modem completely offline, requiring the modem to be reset to get reconnected. So I decided I would spring for an Airport Extreme Base Station, figuring the router was bad.
Well I get home with the new AEBS hook it up, and does the same thing. Apples menus and troubleshooting guides. (The main reason I decided to get the AEBS) Well after going through the setup, it says it is not receiving an IP address.

I have a MacBookPro running OSX 10.5.8 and I've been connecting wirelessly with my NETGEAR Wireless N Router (WNR2000) for the past week but then all of a sudden I'm not able to connect to the internet anymore. I keep getting this message "you have a self assigned IP Address but may not be able to connect to the internet."
I've done all the basic troubleshooting with resetting the Router to factory setting and also unplugged and restarted my modem and Router and laptop.
I've called my ISP (Time Warner Cable) and they've gone through the same troubleshooting with me. I know my internet works as I've been using Ethernet and it works. The person over at Time Warner and she said that my internet and even Netgear wireless router is giving the right IP address but when i checked my network settings on my computer, the IPv4 address is this: 169.254.52.45.
I've checked on various sites and i found that IP that starts with 169.254.xxx is the default setting for airports. I don't know how to set the right IP on my airport on my laptop? It's annoying because I've tried setting my airport on my laptop USING DHCP with manual address with the correct IP from my ethernet connection but doesn't seem to work. I'm at the end of the ropes before smashing my router and computer to a million pieces.

My Airport Extreme isn't recognizing the IP address from my cable modem. When the modem is connected directly to my MBP the internet works fine. When connected to the router I don't get any internet. I have powered off the modem and router and all devices, brought up the modem first (waited for all lights to come on), powered up the router, then the devices. Still nothing. I've tried deleting the DNS server information and resetting - nothing seems to work. There is a green light on the ethernet port on the Time Capsule so I believe the port is fine.

I have a problem with my macbookpro and connection to internet.
1 week ago my computer as stopped to connect to internet.
I was used connecting with my airport express, but at one point my macbook pro stopped receiving ip adress from interenet.
the message on the network connection is Airport is connected to the network. Airport is does not have an IP address and Cannot connect to the internet
I have try everything...:
the Airport is working becouse all the others computers inside on my office are working well with airport.
If I connect my computer with a cable I have the same problem.
I have reset and restart Airport and computer.
I have let my connection and computer disconnected and switched off for 24 our.
I have verifyining that is not an hardware problem because I have installed a fresh OS on an external drive and when I boot from the external drive everything working well.
The OS is on boot installation 10.4.9
the machine is a Mac book pro 17 2.16 GHZ intel core duo with 2gb 667 Mhz.
My problem is that on the old installation I have a lot of software installed and will be take a lot of time doing all the new installation. I wondering if there is a way to recover the situation.

iBook G4 shows that the airport has full connectivity (full bars) yet it doesn't connect and states that there is no IP address. The iBook connects using its internal airport to a Netgear Router. There is a PC that runs windows that is connected to the cable modem. For a month or so both computers were able to access the internet simultaneously. All of a sudden the computers are unable to access the internet at the same time. When I attempt to connect at the same time my Mac gives me an error stating that another IP is in use and so I can't connect.
How can I give my iBook an IP address so that both computers can be online at the same time?

I'm trying to keep track of wireless clients joining my network. The AirPort Utility "Logs and Statistics" button (under Advanced) allows me to see what DHCP leases are out and a list of wireless clients. But it's very annoying reading a long string of Hex to know which device it is!
Is there some way to assign a name or label to each MAC address within the Airport Utility? And Yes, I could use pen & paper, but what's the fun in that?

i am trying to extend a network with an airport express but the airport express cannot get a valid IP address and flashes amber.
my setup is as follows: netgear router/modem which handles PPPoE connected via ethernet to time capsule which handles the wireless network.
time capsule is working fine and has a valid IP address but airport express doesn't.
i have checked 'allow this network to be extended' on the TC, and connection sharing is in bridge mode.
i wonder if someone could help me troubleshoot this

As the header says, the fan in my Mac Pro is now operating at a constant 2700 rpms and, per iStat, believes that Core 4 is at 260 degrees. This is from COLD startup as in overnight. All other cores are operating in the low to mid 70s. So, obviously it's impossible for core 4 to be 260 degrees on startup and highly unlikely it would be that hot, ever. I've done the SMC RST thing both ways (button pushing and unplugging).

I am a comitted Mac switcher trying to put my lovely new MacBook onto the office Windows network. I can connect to the office wireless network (WEP key etc) and the little radar Icon in the menu bar lights up. However, I cannot get the MacBook to obtain an IP address via DHCP. I just keep getting the default self assigned address (169.....).
However, when I connect to the network via a cable using the built in ethernet connector, I get the DHCP address just fine and everything works OK.Also, if I assign an IP address manually to the wireless card (checking it is a free address!) it accepts the settings but I cannot network, not even a basic ping of another machine on the local internal network (all our internal machines are using 10.0.0.x addresses and 255.255.255.0 sub net)The DHCP server is not in the wirless router but is a Windows server machine.This is driving me crazy. I have called Apple care and they just dont want to know because there is a Windows machine in the mix. I expected better from them,

I just installed my new airport extreme base station.
I want to set it up for Mac Address filtering. Can this be done? I only see where it can be set to allow certain times only.
I want to set it like my old D-Link router where only the Mac Addresses listed are allowed on the network, even if the network password is correctly entered.

I'm trying to add a new MAC address to the access list of a AirPort Extreme Base Station.
For whatever reason, it won't accept it. When I finish entering the address, the add button is grayed out. If I try other valid addresses, it works fine. For some reason, something about this address won't allow me to add it.

I use Mac OS X Mail and generally have very few issues. However, I ocassionally receive emails which I know are formatted as HTML, but they nevertheless show up as text... and sort of jumbled text at that (i.e., with URL links expanded inline and other issues that cause the email to be difficult to read). It doesn't happen extremely often, but it does happen often enough to be annoying. I have Mail sync'ed to several accounts: one POP3, and two IMAP as I recall. It has happened with emails retrieved from each service at one time or another.Â
As I understand it, an HTML email usually also contains a text version within the content... and each mail client has to recognize a given email as either HTML or text (or RTF). Indeed, I can view the raw source for the email in Mail, and I see in the payload of the email statements such as "This is a multi-part message in MIME format" followed by sections denoted as Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: base64 and later as Content-Type: text/html; charset="utf-8" Content-Transfer-Encoding: base64. It just seems that Mail occassionally ignores the text/html section.Â
Is there a way to force Mail to switch display of a given message to HTML or to text? I see options to select "Text Encoding" under the Message menu bar option, various stylistic choices under the Format header, and even the View Raw Source option under View | Message menu bar option. This last option (View | Message) also has some options regarding display "alternatives" (plaintext, best, next, etc) but all are greyed-out. Perhaps this is the issue and Mail is simply not understanding the HTML due to a slight mistake in the format of the content and it thinks it is only displayable as plain text?

I suddenly cannot access the several thousand photos in my iPhoto Library. I believe my computer must have automatically downloaded and upgraded the version I previously had. Now I get an error message that reads: The photo library needs to be upgraded to work with this version of iPhoto. Your photo library will not be readable by previous versions of iPhoto after the upgrade. The upgrade process for very large libraries may take an hour or more to complete. I still need my images able to be read by previous versions since I go back and forth editing between older desktops. Is there a way to access the photo library without okaying the upgrade? If I reinstall an older version of iPhoto, will I lose the existing library of photos?
