Ethernet Card Stopped Working (BCM5785M)

My ethernet card stopped functioning about a week ago, at the time I thought my cable had died and did not think to much of it. Then I checked the cable in my desktop computer and it worked fine and was able to connect to my router as well as the interent. To the best of my recolection I did not install any new software that may have cuased the problem, just standard pacman package updates. I ran throught the Networking wiki to try and see if I could find anything wrong but was not able to solve the problem. The odd thing is when I try and connect to my router I obtain and IP address of 192.168.1.128 which to my recolection was a fall back address when an error occurs. I normally will run my laptop on my ethernet card just becuase of shotty wireless router suppled by my ISP. I am able to use my wireless card without problems, other then the substandard performace of the wireless router, so my networking appears to be generally functioning on the computer.
- Lspci -v gives the following output for the network card.

I went to Broadcom's website and the tg3 driver was the correct driver listed for the device.
I checked to ensure that the tg3 module was loaded and running at start up as well which it was.

The firmware out of date looked odd to me but seems to be a common thing with the driver at least when I searched the net. I found that message appear several times but without anything posted about my specific problem.

Well thanks for the compliment. this is my first post here but not my first go with linux. I started using linux back when Red Hat was still avalaible under the GNU as a free distro. Then to Fedora in beta, Gentoo. Ubuntu, and now Arch. I have been running arch for about two years and just have not needed to post do to generally finding my answers in the wiki or on a forum post either here or else linuxquestions as well. I guess that leads me to say that this distro is one of the most well documented ones I have ever used. Gentoo would be the only other who comes close but that is needed just with the complexity involved in the install.

I will say though that everything looks perfectly in order. The DHCPCD is good, and it shows that you are connected. I assume you recognize an error as a browser does not connect. But have your tried other web-tools to see if they can connect? A good starting point would be ping. Try each of the following:
ping -c 3 google.com
ping -c 3 8.8.8.8
and post the output here.
I did try a ping on the google site both with the name server as well as the ip while going through the network wiki. I also tried a ping to the router it self without success.

I guess one thing I did forget to mention is that the LEDs on the ethernet card seem to be functioning as well when I plug the cable in.
EDIT:
Interesting Update.
I was able to connect to my router as well as the internet by switching over to a static IP. I made sure to set it as high as possible but it did work. I was browsing around and saw another post on the forums and someone suggested to switch to static IP to help troubleshoot the problem.
Here was the post I found: https://bbs.archlinux.org/viewtopic.php?id=143183

Ethernet card stopped working after a bad blackout.

Hi everybody,
we had a bad blackout yesterday night, with a terrible peak of electricity before that. When I turned my mac mini on again, it would not see any more the ethernet card.
In the system preferences it did not appear any more, and when asking for "Network Port Configurations" the Integrated Ethernet appeared grayed out. From the command line i then tried "ifconfig en0" and the answer is: "ifconfig: interface en0 does not exist".
I removed the interface, with the intention of adding it back again, and the only possibility that comes up in the menu (besides bluetooth and airport) is a "6 to 4" interface (which I have no idea what it is). Tried that, but it didn't seem the right thing to do...
I then switched off the computer and started it with the self test disk. The disk did not report any problem at all, however the ethernet address that seems to be there makes no sense to me (it contained characters like ")" and "!"). I restarted, and gave a look at the log files in /var/log/system.log and the only suspicious thing I see is:
"Jul 29 18:38:18 my-computer /System/Library/CoreServices/mcxd.app/Contents/MacOS/mcxd: MCXD.initializeDirectoryServices: Unable to get the ethernet address "
Is there anything else I can try to see if the ethernet card is still there and functioning?
Thanks a lot in advance,
Luca

Hi Luca, and a warm welcome to the Forums!
It does sound like it is a goner, but just to be certain it's not some damaged Software...
Boot from your Tiger Install Disk, put in your language, then look up top for the Menubar, use System Profiler from there, if Ethernet still doesn't give an addy, well, that's about it.

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.

Intel wired ethernet driver stops working

We have this issue with several T400 and T500 series ThinkPads that the Intel ethernet driver stops working after a while. All this started to happen maybe a month ago. We have both 32- and 64-bit Windows 7 OSs.
Wired ethernet works ok first, but after a few hours or a day or two this yellow exclamation mark appears on the network icon and it says limited or no connectivity. Wired network stops working and there is nothing we can do to fix this other than reboot the computer. It doesn't even shut down properly, just says "Shutting down" forever and blinks the HDD led maybe once a second. So we have to force it and after booting everything is ok until the next time this happens.
When the network stops working, nothing can be done with the driver because everything just hangs. You cannot disable the connection or uninstall the adapter from Device Manager or anything. Unplugging the ethernet cable does not help either. There is nothing about this problem in the Event log other than about the symptoms of not having a network connection.
What could be the source of this problem? Do you have any ideas about how to diagnose this problem further? We have the newest driver and I have also tried the newest driver from Intel.

Go to Local Area Connection (Wired Intel adapter), Properties and the Configure button, in the Power Management Tab UNCHECK "Allow the Computer to turn off this device to save power".
Window7 does NOT always resolve IP and DHCP when it come out of sleep etc. All attempt to release/renew are in vain. I have seen this on various systems for some time. Occassionally a router reboot fixes it but most of the time is the PC. Frustrating but for Wired use this should always be disabled if you're using it a lot. Power savings is not in your best interest.
Let me know if that does it.

After i updated to mavericks, my usb ethernet adapter stopped working.

I'm not sure why, but when I updated my software to mavericks, my USB ethernet adapter stopped working.

I'm using that adapter:
http://www.edimax.com/en/support_detail.php?pd_id=445&pl1_id=5&pl2_id=26
After I updated to Mavericks, I installed the driver in this page, but it didn't work. Then I googled "AX88772" which is my adapter's part no. or something like that, and I installed that one:
http://www.asix.com.tw/download.php?sub=driverdetail&PItemID=97
I wasn't expecting that work but that did work. So, I think the solution of the problem is finding the right driver. I hope you solve your problem too.

Satellite A - LAN card stopped working

I purchased my A series in April 08 and a few weeks ago the LAN card stopped working. It just won't connect and can't get emails and doesn't connect to any web pages.
Currently have the computer working off wireless but does anyone know how to fix the LAN Card problem.

Hi!
Which Satellite notebook do you have exactly?
Does the notebook recognize a LAN cable if you plug in it? Is the LAN connection enabled in Windows?
Try to update the LAN driver and the BIOS. Both you can find on the Toshiba website:

5233 Memory card stopped working!

Hi,
I've had this phone for almost a year, it's good but there have been few problems.
I have an 8 GB memory card, which I had to reformat recently. Today I was downloaded a theme from nokia store. But suddenly my memory card stopped working. I re -inserted it but it doesn't show on phone.
56 MB of my phone memory and 6.5 GB of my external memory is free. I cant reformat cause memory card is not showing on phone.
Another problem that's appeared is that while typing, if move the cursor back it goes through each alphabet instead of each word.
3rd thing is wen I first posted here there was an option that allowed me to check response via email. Its not here anymore.
Please help all my data is on memory card.
Regards
Solved!
Go to Solution.

Hi mtank,
Thanks for your post.
If the memory card can't be read in the phone try your memory card in a cardreader connected to a PC to verify if the card is readable still. If it is copy all content to the PC and format the card. Then check the card in the phone and if it is accessible copy all content back to it from the PC. If you still can't read the card on the phone replace it with a new one. You can copy the original content to it from the PC first.
Hope this helps,
Kosh

After Service, Airport card stops working randomly on macbook pro 17" early 2009

Hi,
So after the last time my computer was serviced, the airport card stops working randomly on moving the screen.
Upons restarting the computer, it sometimes says wi-fi hardware not installed. Then, if I move my machine around,
lift it up, turn it around, place it back on the table and restart it, it works again. I don't understand this.
And all this started happening the moment my warranty ran out. Extremely frustrating!!

It may be possible that one of the following may be the issue:
The internal AirPort Extreme card is not seated properly.
The internal Wi-Fi antenna connector is not seated properly in the AirPort Extreme card.
The internal AirPort Extreme card's connector is faulty or damaged.
The internal AirPort Extreme card is faulty.
To get an idea on how the Extreme card is installed, please check out the following iFixit article.
