Neo platinum on0board ethernet stopped working

all of a sudden i have lost my internet connection. I tried everything including a format and its still not working. I get a link light on the nic port and everything looks good in the device manager, but if i have the cat5 cable plugged into the on-board port the system hangs up for a few minutes and when it finally comes to i have no net connection and can't communicate with the other 2 pc's on my home network. Tried a few different forceware drivers and when it tries to load the ethernet drivers it hangs up during install.  do i have a dead on-board nic?

Freakaloin,
Which Neo Plat Mobo do you have?
Take Care,
Richard

  • USB Ethernet stop working after 10.7.5 update

    After updated to 10.7.5, my usb ethernet stop working, and always shows it doesn't connect.
    Reinstall 10.7.5 make no difference.
    How do I solve it?
    Thanks!

    Or download it directly from ASIX Electronics instead of driversworld.us.

  • Ethernet stopped working suddenly

    I've been reading various topics on this board and it seems like many people have this problem but there are not many solutions.
    My problem is that my ethernet stopped working suddenly. I've taken the following steps:
    - reset the cable modem
    - reset the router
    - turned off my ethernet card and rebooted the computer then turned it on again; renew DHCP ip
    - create a new location
    Does anyone have any suggestions?

    I'm not an expert, but here are a few suggestions & questions:
    • Did you reset things in the order you wrote them in your post i.e. modem before router? (That can be important. Also I find it takes my modem a couple of minutes to establish a connection, so I wait for a while before I turn on the router.)
    • Do you have any other computers wired up? Do they work?
    • Have you tried setting the computer location to Automatic?
    • Does your Modem have LED readouts which indicate when it is connected to the Internet and to a router?

  • Ethernet stopped working at last update

    Hard-wired ethernet stopped working after the last update.
    Wireless works.
    I have a trendnet wireless router. When the imac is connected via physical ethernet cable, it can actually ping and http to the trendnet and other machine on the same subnet just fine. However, it can't get beyond that. Looked at routing table and it looks fine.
    When i take the same imac, connect via wireless to the same trendnet router, everything works.
    Routing table looks identical.
    PC's in same line can be hard-wired to the trendnet router and work fine as well.
    Checked for more updates and none available.

    This is and old problem that as far as I know has not been resolved. You might try a search here to see all the other posts concerning this.
    I had a similar problem with my brand-new Mac about a month ago. It worked on my wireless system when I first booted it up and then after I updated it about 20 minutes later, it began to repeatedly drop the Internet connection. After a week of fighting it, I had to switch to Ethernet thus having only my Mac wired while my PCs cruise right along on wireless.
    When I first tried the Ethernet hookup, it still dropped a couple of times. It has not done so in the last 2 weeks, knock on wood. However, I am afraid to try wireless again as I may never get Ethernet back. Perhaps, just perhaps, Apple will resolve this in the next update if they even are aware of it.
    Sorry for no answer to your problem. I hope someone sooner or later is able to resolve this.

  • Both thunderbolt display and ethernet stopped working at the same time

    I use recent Macbook pro 13inch retina.  I use both of thunderbolt ports on ethernet and display.
    I was messing around with application, and I found chess game. I played it for while than my display and ethernet suddenly stopped working.
    I do know ethernet and display is working fine because My roommate still have access to the ethernet, and My xbox still works on my display monitor.
    So, I suspected its thunderbolt problem, and I reinstalled Mavericks twice and reseted SMC and NVRAM, which didn't solve anything.
    Do you have any suggestion before I take this computer to Apple store?

    So the ports still work, and the display still lights up when you use it with your xbox? Are you sure about the xbox part, I didn't think the thunderbolt display worked with an xbox.
    https://discussions.apple.com/message/24060376#24060376
    Do you have the LED Cinema display? Look at the back, do you have 3 USB ports or 3 USB ports, firewire and ethernet?

  • [SOLVED] Ethernet stops working after a while

    When I work on this computer, the ethernet stops after a while, sometimes this is after 2 minutes, sometimes after half an hour. When I do
    sudo /etc/rc.d/network restart
    everything works again for a while. The internet doesn't work in chromium nor pacman so it isn't just one application.
    Anyone knows how I can find the cause of this?
    Thanks already!

    Also, tell us about your network.  Are you plugged into a corporate or school network? your own private router? into a DSL or Cable modem?
    When it stops, what is the output of ip link  ??
    of ip addr  ??
    of ip route  ??
    What is the make, model and chipset of your NIC?

  • Solaris 10 x86 patching, ethernet stopped working

    Hello,
    This morning I ran smpatch download, install in single user mode. Rebooted, and my ethernet has stopped working on elxl0 3com 90XX LAN driver. There does not appear to be any problems in dmesg. Anyone having similar problems?
    I have been keeping up-to-date on my patches, this morning I remember seeing a kernel patch, a s4/usr patch. And a couple of others.

    Please disregard, it appears there was a recent network change that seems to have affected this system. Thanks.

  • USB Ethernet stop working after hotplug

    I have found that my Apple USB Ethernet dongle stop working if I plug in another USB device. This happens both using a USB hub, and when plugging directly into the MacBook Air. I also see this problem when using a similar dongle from another supplier (called AX88x72A). The USB Ethernet dongle works fine after booting, with status "Connected", but if I plug in another device like my phone or a  USB drive, the status changes to "Cable Unplugged" after a few seconds, ifconfig no longer show the en1 interface, and syslog gives a few error lines such as:
    Fri Jan 13 13:17:19 Airbook-II kernel[0] <Debug>: en1
    Fri Jan 13 13:17:19 Airbook-II kernel[0] <Debug>: Ethernet \[AppleUSBEthernet\]: Link down on en1
    Fri Jan 13 13:17:19 Airbook-II kernel[0] <Debug>: AppleUSBEthernet::prepareForFlash - Link down, Device 87bf600
    Fri Jan 13 13:17:19 Airbook-II kernel[0] <Debug>: AppleUSBEthernet::prepareForFlash - Link down, Device 87bf600
    After this, I must reboot the MacBook Air to get the dongle working again. Do anybody know how to force the AppleUSBEthernet driver to rescan the device tree (or something similar)?
    With regards,
    Birger Retterstøl Olaisen

    I have exactly the same problem here (MacBook Air 2,1 - OSX 10.6.8). After several tries (and reboots!), I've found that an unload/reload of the USB Ethernet driver works.
    Note that operation is not automatic: I have to execute commands in a terminal in order to retrieve my Ethernet connection... but it is far better than a reboot!
    So, if  you want to test my method, once you have plugged a USB key (or after an hotplug of your USB-ethernet dongle), you can execute these commands on your terminal (note there are 2 lines and no space in the kext name, a space may be inserted by this forum):
    sudo kextunload /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/AppleUSBEth ernet.kext
    sudo kextload /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/AppleUSBEth ernet.kext
    Of course, i've made a small script with these commands, and copied it on my PATH so it is even easier to execute it. It works perfectly for me, and I hope it could help.

  • Wired ethernet stops working on c2d MBP

    I am a new 15 inch C2D MBP owner and I'm just starting to learn all the Mac stuff... I need your help because I have a serious problem with wired ethernet stability under macOS. I need to know if it's something specific to my machine or if anyone else has similar problem.
    I am connected to a LAN with a 10/100 Mbit switch. I'm using a good cable (checked!). And my connection seems to hang from time to time. Usually this happens under heavier load (torrent plus multi-tab browsing), but it dies sometimes during casual browsing or checking for system updates. And it's anywhere from 3 minutes to 12 hours between hangs...
    The symptoms are strange. The connection seems to be on, but there's a sudden surge in bad packet received number and the network connection stops working remaining on-line. Putting the machine to sleep or manually shutting down the line helps immediately. I'm using:
    sudo ifconfig en0 down
    sudo ifconfig en0 up
    At first I suspected hardware problem but the same line works perfectly under Windows (with even higher load, and tcpip.sys patched to 1000 connections).
    It acted like this from the very first moment I got it and I have no clue if I should contact service or wait for a patch or maybe just stick to Windows (just kidding)...
    I've browsed the forum and it seems I'm not the only one with the problem:
    http://discussions.apple.com/thread.jspa?threadID=649927
    but this topic is unsolved... There's nothing really strange in system.log:

    evans_re,
    does the trackpad not work? If it works, you could try selecting “Shut Down…” from the Apple menu.
    As a last resort, you can hold down the power button for approximately ten seconds, which should force a (non-clean) shutdown.
    If your keyboard is completely non-functional (excepting the power button), then you should take it to an Apple store or other qualified service facility.

  • Ethernet stopped working

    My ethernet has stopped working, can I get it working again or does it need repair?
    I've rebooted the iMac and during boot I can see the router port light shows some activity but then switches off before boot is complete. The ethernet shows as not connected in System Preferences/Network. I have tried changing the ethernet cable. I have tried moving the ethernet cable to another port on the router. I have tried rebooting the router.
    Can anyone offer further ideas?

    Hi,
    I have had this problem with my old iMac 24" and now my newer (20 month old) iMac 27".
    Have had both these machines to Apple and have been told that the ethernet port is faulty. The only solution is an expensive board replacement.
    This appears to be a serious weakness with the iMac, as I know of others with the same problem.
    My 4 year old PC (Windows OS) on the same network, does not have a ethernet problem, neither does my Macbook Pro.

  • Ethernet stopped working today.

    Today I started my PowerPC to send some emails and my Internet connection was no longer working.
    I looked in the Control Panel "TCP/IP" and the "Ethernet" option was missing. The only two options I have are Apple Talk and PPP.
    I got one error message about the "Ethernet" but did not write it down.
    I've been trying to figure it out all day.
    Does anyone have any suggestions?
    OS 9.2.2

    Thanks,
    Mike

    Hi, Michael -
    Make sure the cabling between the Mac and the modem/router is secure, ditto from the modem to the wall (phone line or cable).
    One experience I had years ago - one of my cats fanged the phone line going from the modem to the wall. The mark on the sheath was near invisible - replacing the phone cable and having it work lead me to examine the cable inch by inch until I found the break.
    Make sure that both the extensions named Shared Library Manager and Shared Library Manager PPC are enabled (checkmarked) in Extensions Manager; ditto any extensions whose names include Open Transport or OpenTpt, and the extensions named Apple Enet and Apple Enet DLPI Support.
    It can help to throw away the preference file named ASLM Preferences.
    Restart after making any changes.
    Make sure the modem or router (whichever is connected directly to the Mac) is on and warmed up before booting the Mac.
    It can sometimes help to reset the modem. The quickest way to do that is to pull its power plug, wait a minute or so, then plug it back in. Some newer modems have a reset button.

  • G4 ethernet stops working, system prefs hangs

    Hello, I have an old g4 power mac working as a server. O.S. is 10.4.11, connected with ethernet over several switches and a ( new ) router with fixed i.p. addresses. The other computers are intel machines with MAC 10.6 . This configuration has worked fine for years. (of-coarse with the different O.s.ses)
    When I start up the g4 it works fine and its disks are accessible by the other computers; but after a few ours the connection disappears. When I try to have a look in systems prefs- network the systems pref hangs itself.??? Can anyone tell me watts going on here?
    The things I changed lately are the new router and "snow"
    Thanks in advance
    Jos.

    Yes, ethernet is there, correct I.P. number, and stronger: internet is working!

  • Ethernet stop working and work back after a reboot

    Hello,
    Sometimes, may be one a month, I got a problem with my network, suddenly I can no longer ping anything on my network while the network configuration on mac os x is still fined (ip configured, ethernet link is up, ...)
    I tried a lot of thing to make it work back : complete network reconfiguration, putting the interface down then up from terminal (with ifconfig), unplug & plug the cable... nothing work.
    The only way to make it work back is to reboot like if their is a bug in mac os x or like if the ethernet controller is freezed and need a reset.
    Had anyone already heard of such problem ? I'm wondering if this doesn't append when the CPU is under a high load, so the mac is quite hot, may be to hot for the ethernet chipset ?

    I am having the same issue. It's been happening more frequently to me, about once or twice a week. But everything else sounds exactly the same.
    Any help anyone?!?!?!?!?!?!?!

  • Why did my ethernet stop working on 2008 Aluminum MacBook after upgrading to Mavericks?

    At home (using an AirPort Extreme) my ethernet works, but anywhere else I go it will not recognize.  I have tried manually setting the IP and removing, adding the ethernet connection.  No matter what I do it still says "Not Connected" it states that either the cable is unplugged (which it isn't) or the connected device isn't responding.  I am assuming it is a driver/firmware issue in Mavericks that doesn't support the DHCP discovery.  Can someone please shed some light on the situation?

    I already did that and still nothing.  My 2012 Retina MacBook Pro running Mavericks works fine, so I am confused as to what is causing this on the 2008 MacBook.
