Missing ethernet card 27inch iMac

Since a couple of days my 1 year old iMac seems to have lost touch with its ethernet card. In network settings I am unable to add an ethernet connection. When I run more info from about my Mac the system now tells me "This computer does not appear to have any PCI Ethernet cards installed."How the **** did that happen? It has been working flawlessly for 12 months. I already have reset the pram etc, without any positive revival of the network card. Is there anything I can do/check to find a solution without taking the computer to a service center (support has just finished)?

Try creating a fresh user account and check the Network preference pane under that one. Does the issue remain or are you able to use ethernet there? That will tell you whether the issue is account-specific or system-wide.
If it is system-wide, try rebooting the machine and holding down the "D" key after the startup chime to boot into Apple Hardware Test (this is usually installed on a partition of your HDD on newer machines. If not, you can pop in whichever install disc is labeled for AHT and do the same procedure). Run the "extended" test and see what the results are. It could be that your NIC has gone bad.

Ethernet card issue...can't get rid of self-assigned IP

Hi folks,
I am using an circa 2005 iMac G5 PPC desktop with 10.5.8. I am trying to connect the iMac to my Time Capsule via ethernet cable, but seem to be having problems with my ethernet card. When I plug into the TC ethernet port, the TC drive, does not mount and I cannot access the worldwide web.
When I go to System Preferences --> Networking, the tab on the left for ethernet connection shows a green dot, says "self-assigned IP" and the status says "connected" PRIOR TO CONNECTING THE ETHERNET CABLE TO THE TIME CAPSULE. It shows a "self-assigned" IP (DHCP selected) of 169.254.69.249, even though I know my TC is 10.0.1.1. Turning the ethernet off then back on, renewing the DHCP lease, nothing seems to be able to make this 169 IP address go away. The wireless connection to the TC is just fine... everything does what it should, I just can't get the ethernet cable connection to work.
Out of curriosity, I went to the System Profiler, and on the network tab it shows ethernet IPv4 169.254.69.249 (name en0).
I know it's not the Time Capsule, as I connected my laptop to it just fine via ethernet. The TC was IP 10.0.1.1 and it assigned 10.0.1.5 to my laptop (I have a variety of devices on my network), and I was able to transfer data and access the internet with no issues whatsoever.
I live in an 32 story apartment with a built-in ethernet network and ISP included in my rent. It's pretty nice, high speed. I connect from the wall to the Time Capsule via ethernet (circle dot connection port, so I know I have the right port), and then wirelessly out to a couple of laptops, a couple of Airport Express, and of course my desktop.
Bottom line, I think the ethernet card on iMac G5 desktop has gone bad: A few questions:
(1) Any ideas what may be wrong? Has anyone seen this self-assigned IP thing that won't go away?
(2) Any ideas how to fix it?
(3) How much will it cost? It may be time to replace my 6-year old desk top computer.
Thanks, Andy

I've swapped out several cables still with no luck, and the current cable definitely has 8 pins and worked with my laptop, so I'm confident it's not the cable. Also, the Time Capsule seems to be OK, because it too worked with my laptop using the same port. The only variable that doesn't seem to be cooperating is my desktop computer.
Also, I have tried to manually assign an IP consistent with the network & appropriate subnet mask. It seems to take the IP address manually, but still I can't get internet access, and can't ping the Time Capsule in network utility either.
Finally, when I connect the desktop directly to my wall outlet, taking the router out of the equation entirely, network diagnostics shows ethernet failure...
Does that sound like a bad ethernet card?
What does it take to replace an ethernet card in an iMac G5?
Cheers, Thanks, Andy

Ethernet Card Not being Detected on my iMac 27Inch (Mid2010)

Hello,
I have only had my iMac for a couple of months, and it appears to have developed a fault. I have a network router, and a network cable is plugged in however, the Network Panel keeps reading as "Cable: Unplugged". It is not, i can assure you.
When I got into the About This Mac > System Profiler, it has "This computer does not appear to have any PCI Ethernet cards installed." under the Ethernet Card option
I'm currently on Wireless (very skechty), and that also keeps dropping out even though the router is less a foot from the iMac.
Any Solutions or Advise please?
Thanks Phill C

I have the same problem after I installed LION on my imac 27" (Late 2010). It was working for few days and then after I restarted my computer my network card just went dead. Since I have several partitions I can boot back to Snow Leopard and it shows me ethernet just fine. So it means that LION has bugs and many bugs from what I can tell. It is wide spread problem and not sure if apple is doing anything about htis.

Ethernet Card Missing

My ethernet connection has not been working--I have not used it for sometime, so it is possible it's a has been a problem for a few months, but I also upgraded to Snow Leopard recently. Someone told me to verify the ethernet cards' existence in my Utilities folder, and alas, it is missing. What can I do?

Everything looks ok except for the "Unplugged" report while plugged in. I am unable to duplicate that result except by being unplugged, so I can only guess that there is a hardware problem with your MacBook's ethernet jack or elsewhere on the boards inside, and the plug you're inserting somehow can't be recognized. Hopefully it's still within warranty or AppleCare.
Has the Apple Hardware Test reported any error code? That code will be a help to the repair folks if it has. Best of luck with getting it fixed, or you may be restricted to using wireless - could be worse.

New 27inch imac ethernet not working!

About to return it to the apple store.
Wi fi rock solid
Ethernet gets IP address
All green lights on
diagnostics says all good
new ethernet cable
but imac refuses to connect to anything via ethernet!
tried router with mac book and ethernet is brilliant and solid
Anyone had this or got any ideas?
Thanks
Gary

Thanks for your quick response. I had another look at the addresses-sorry my mistake they are slightly different
wi fi192.168.0.3
ethernet 192.168.0.2
I have tried turning of wi fi -it made no difference.
I'm running out of ideas.

Time Machine not working after ethernet card failed

A couple of weeks back my iMac Core Duo's ethernet failed. As a logic board replacement for a 3.5 year old iMac would be expensive I instead bought an Apple USB Ethernet adapter (which works great). However, now Time Machine will not work, it says it cannot find the built in network interface. It does not matter whether I connect the external drive directly via firewire or over the network to my Mac Mini (which will backup with either connection).
Here is the console error:
+Time Machine: Error setting backup path: Error Domain=com.apple.TimeMachine.Preferences Code=-1 UserInfo=0x1864bdf0 "Time Machine could not be configured. The built-in network interface could not be found."+
+_CSBackupGetMachineMACAddress - IOServiceGetMatchingServices did not find an ethernet service with kIOPrimaryInterface true+
I tried the instructions on the Apple Support page http://support.apple.com/kb/HT3275#5, but that did not work. Can anyone help?

Hi, and welcome to the forums.
It's a long shot, but try a "Full Reset" of Time Machine, per item #B3 of the Time Machine - Troubleshooting *User Tip* at the top of this forum.
TM uses your Mac's Ethernet Address, which is embedded in the hardware of, guess what, your logic board, to identify your computer. This is how it keeps the backups for each Mac separate, so you can back-up more than one Mac to the same place without conflicts.
To find this address, use the System Profiler app (click the Apple icon at the left of your Menubar, then +About this Mac,+ then +More Info.+
Select Network in the sidebar, then Ethernet then find a line like this: +*MAC Address: 0a:1b:2c:3d:4e:5f+* That code, omitting the colons, is what TM puts in a hidden file on your TM volume to identify it as your Mac's backups.
Since your internal Ethernet card failed, you may not see that at all. If not, neither, apparently, can Time Machine. Other than getting a new logic board, I don't think there's a workaround.

New 27inch iMac keeps asking to choose Wifi network. How do I stop it?

I recently purchased the new 27inch iMac and i'm really enjoying everything except this little annoyance. Everytime my computer restarts or goes to sleep, it automatically asks me to join a wifi network when I start it up again. I've already selected my home network as my default network that I want it to connect to but it keeps asking me to choose a network anyways.
If I 'x' out of the the wifi selection window, it will automatically connect to the default network it's supposed to. I just want to know why it's asking me every single time I log in.

seems that the card takes a few seconds to wake up after the iMac awakes from sleep. It eventually connects to the prefered network. But the dialog box continues to show up when the the MAC is waken up...

G5 Can't See Gigabit Ethernet Card

Some months back, I installed a gigabit ethernet card into my G5. It worked fine for a few months, then stopped working with a message: The cable for PCI Ethernet Slot 3, Port 2 is not plugged in. I wasn't working on the project that required that connection, so I just let it go. Now I need to connect to a different gigabit switch. I installed a new D-Link card into the same slot as before - same result. I moved the D-Link card to a different slot - and got the same error - still referring to Slot 3. Just for kicks, I installed the old card back into slot 2 (the one above the video card). Same error - and no mention of finding two cards or of anything in the other slots. It seems as if somehow all of the PCI slots are being ignored.
Running the System Profiler, I get a "No Information Found" for PCI Cards. None of the lights on either ethernet card come on. Any ideas? Everything else on the machine seems to be working correctly - the built-in ethernet is fine. There are a lot of drives connected to the system (4 on the FireWire 800, 1 on FW 400, 4 on USB). Is there some way to force a re-scan of the PCI bus? or turn it on?
Thanks!!
G5 2 X 2 GHz Mac OS X (10.4.8)

Thomas -
Yes - I tried swapping slots. A gigabit card worked fine in slot 3 for several months. It stopped working - I figured it was the card that was th eproblem. I have since replaced the card, and then moved the new one to a different slot. The Network control panel still reports a card in slot 3, even though there is nothing in slot 3. The new card is in slot 4 (and just for kicks the old card is in slot 2). Neither of these is recognized by the the System Profiler or the network control panel.

I have installed the agent 10 or 15 times and one installation has failed, no error appeared during the installation but I am having inconsistent issues with my ethernet card not working here and there. We rebooted and can log into Novell client but the login prompt did not appear for ESM client or the icon was not in the systray. Everything seems to work, besides at times (a couple times today) it terminates his ethernet card/connection. I would re-image his computer but he has several applications and it would take several hours, so I am hoping someone has an idea to fix this issue. So I was trying to figure out why he did not get the prompt to login and why it's not in the systray and it appears to not have completed the install? I checked the add/remove programs, its not listed within their, I also checked the registry and found nothing for endpoint within their, but the files are within c:\program files\novell\zenworks endpoint security.
I have also tried uninstalling it but that fails due to it "not being installed", and it will not reinstall over itself either.
I did notice that stuninstdrv.exe is running in task manager. Any help would be great...

If you are searching the registry, check for the "Senforce" string. It should be at HKLM\Software\Senforce
Try running the install program for the ZSC with the following command line:
setup.exe /V"STUNINSTALL=1"
If you've specified an uninstall password, try this one instead:
setup.exe /V"STUNINSTALL=1 STUIP=password"" (please note the double quote at the end)
Let me know if that helped you.

How to remove sd card from iMac

hi how to remove sd card from imac ,thanks

If your machine is in warranty, be careful not to do anything more that might damage it when removing it from the optical drive. You might even be able to convince an authorized service technician to carefully remove it under warranty from the optical drive. It is a design issue that lets people accidentally insert the SD card in the optical drive. Of course if that's the only copy of your information on the SD card, be sure to let them know that, so they are extra careful not to damage it when removing it.

How can i connect my ipod touch to my 27inch iMac via bluetooth?

I just bought a new 27inch iMac and i have an iPod Touch (one just before they came out with iPods with cameras).
What is the step by step procedure to connect these 2 devices via bluetooth? Or is that even possible? Bluetooth is already activated on the iPod.

You don't. This is not and has never been a feature of ipod. Sorry.
Bluetooth is for stereo headsets/speakers and some peer-to-peer apps from the app store.
Not the news you wanted. Sorry.

Ethernet card no longer showing in ifconfig [solved]

Hey,
Normally I don't have any problems with my networking, but this morning my wireless decided not to work. I haven't made made any changes in the past couple of days, so unsure what has caused it. Last Syu was on Thursday and every day including up until last night was fine.
So spent a while trying stuff out and stressing my tiny little brain for ideas, quick version is I did this:
netcfg: said interface didn't exist.
ifconfig: didn't list the interface (wireless is usually eth1)
lsmod: confirmed the module (ipw2200) was loaded
lspci: confirmed the card was there
After copying the output of the above commands plus the obligatory rc.conf onto usb to move to this machine (and just before pushing <submit> on a much larger post than this :-) I decided to check the mac address listed in ifconfig with what is on the sticker under my machine. Voila! My wireless has actually moved to eth0. OK, that's that solved. (Wish I checked that first though...)
But that means that the reason that my wireless card is now eth0 instead of eth1 is because my old-skool wired ethernet card is no longer there to be numero 0. Why isn't it working? lsmod shows that the tg3 module is loading (it's an Intel card with Broadcom chipset in a Thinkpad T43) , but it no longer shows up in ifconfig. lspci is not showing it (see below), only the wireless card comes up. Does this mean the hardware is borken? What else can I do to check the card?

Yeah, doesn't give me anything about the ethernet card, but does show the wireless one. No, hang on, just found it. Hmmm, didn't see it before, but I was grepping for 'net' then.
$ dmesg | grep -i eth
eth1: Tigon3 [partno(BCM95751M) rev 4101] (PCI Express) MAC address 00:12:34:56:78:9a
eth1: attached PHY is 5750 (10/100/1000Base-T Ethernet) (WireSpeed[1])
eth1: RXcsums[1] LinkChgREG[0] MIirq[0] ASF[0] TSOcap[1]
eth1: dma_rwctrl[76180000] dma_mask[64-bit]
OK, so it is at eth1 now, that makes sense since I put ipw2200 right at the beginning and tg3 right at the end of the MODULES array in rc.conf to avoid the system getting crossed up while trying load them too close together. Thanks B, so at least we know something is happening at boot time.
Btw, my assumption is that ifconfig shows hardware once it is loaded correctly, is that right? But apart from the modules, what else do I need to do to get it showing up in ifconfig?

Is there a PCMCIA Ethernet card for Powerbook G4 OS X 10.4.8 ?

My ethernet port on my Powerbook G4 is damaged and can no longer be used. I looked into getting it repaired but that apparently requires replacing the entire system board at considerable cost. Rather than take that route, I was hoping to find a PCMCIA card with an Ethernet port but I cannot seem to find any that will work with OS X 10.4.x.
Does anyone know of such a card ?
Thanks for your help !

How old is your Powerbook?
A Mac older than 4 years old may need its clock battery replaced by an authorized service center. The clock battery dying can cause certain ports to malfunction as well. If it is under 4 years old and no surges broke the port, try zapping your PRAM, it may solve the problem once and for all:
http://www.info.apple.com/kbnum/n2238
If it is under AppleCare, there may be no cost at all. Any Mac under a year old is under AppleCare.
Also replacing the system board can be cheaper than from Apple directly if you take it to one of these places:
http://www.dttservice.com/
http://www.powerbookresq.com/
http://www.microdocusa.com/
http://www.macspecialist.com/
http://www.techrestore.com/
In addition, if the port got burnt out by a storm surge or power surge your home/apartment insurance or credit card company you purchased the machine with may pay for the damage. So check each of those sources if you can't find an appropriate card.
http://www.xlr8yourmac.com/ lists a variety of upgrade cards in their database, and may have some ethernet cards you can look at.
By the way, the fact that port is broke suggests the possibility that any other system difficulty you are having may also be related to logicboard issue in anycase, so replacing the logicboard is a good idea if you are noticing other issues.
This thread may yield some clues:
