    Default Missing LAN adapter on p67 extreme4?

    Hey everybody. I recently had a motherboard die on me and I replaced it with a P67 extreme4 board. I booted up the system without reformatting so I could get to some files I wanted to save. Everything seemed to work fine until I ran a Windows update then I lost internet connection. I tried the troubleshooter on windows 7 and it said it could not find a network adapter. I tried installing the driver update from asrock and it also said it could not find a network adapter. The light on the network adapter is on, but nothing seems to be working. I tried reformatting and the same problem seems to be occurring. Any idea what the problem is and how to fix it?

    I had the same problem. I figured out that the problem was coming from installing an optional Windows Update (Accusys) that then bricked the LAN port.

    I have had to install the driver a few times (when messing around with overclocking), which is very annoying. Hopefully the next set of drivers/bios fixes it.

    Do not install the ACCUSYS driver from Windows update. This will break the ASMedia PCIe-PCI Bridge and stop a few devices from working. Uninstall that trouble device in the device manager (check remove device software), and restart the computer. Allow Windows to automatically detect and install the ASMedia controller (and the associated PLX ExpressLane PCIe 2.0 Switches).

    Been wrestling with this issue all day... still yet to find a work around after installing the update. Is there a simple way to rollback all Windows Updates or am I going to have to do a full reboot? The network adapter is still not appearing, can't install drivers, and device manager has nothing left for me to uninstall or remove...

    Are you able to post a screenshot or picture of your device manager Including expanding any raid storage controllers?

    Dear all,

    Please kindly refer to below steps to remove "Accusys Inc–Storage- ACS- 6xxxx" for testing.

    Step1. Click "Start" -> "Computer" -> "Manage"


    Step2. Click "Device Manager" -> "ACS-6xxxx" -> "Properites"


    Step3. Click "Uninstall" -> "OK"


    Step4. Enable "Delete the driver software for this device" option and then press "OK".


    The update is not the necessary, please don't worry about it will caused any side effect.
    Thanks!

    Have a nice day

    Question Re: Missing LAN adapter on p67 extreme4?

    I have the same problem with my board. It happens while playing a FPS game. The game stutters for a few seconds before freezing. Soft resets don't work so I end up shutting the pc off with the switch. When I power back up, the network card adapter is gone and I have no internet access. Sometimes powering off and on a few times works and internet access is restored but not all the time. Most of the tie, the network card adapter shows up missing in the device manager. Sometimes, the network card does appear with an exclamation point in the device manager but the card is nonfunctional. "Accusys Inc–Storage- ACS- 6xxxx" does not appear to be installed because it doesn't show up under "Storage Controllers" or in any other device in the device manager. At the moment, my device manager does show the wireless adapter card under "Network Adapters" but the device does not work. When I right click on the adapter card and click on "properties" and then "resources", it says: Resource Settings: This device cannot find enough free resources that it can use. If you want to use this device, you will need to disable one of the other devices on this system." Any help would be helpful.

    The diagnosis is simple. The network adapter on the board should always show up in the device manager. There is a special case with the PCIe bridge on the board in which everything "attached" to that bridge would disappear if it was uninstalled or mis-configured.

    In your case, if the card can't be seen in the Device Manager and nothing in the system is changing the system hardware or drivers, you have a faulty board or failing chip. I actually had this exact problem on the first revision of the X58 Extreme board because too much heat near the CPU/VRMs would cause the network chip to fail. Adding extra cooling (heatsink/fan) solved the problem and it was also addressed in future revisions of the board from the manufacturer. If you are sure you don't have any overheating issues on the motherboard near the small realtek network chip, then I suggest returning (RMA) the board for warranty and replace service.

    As for the wireless not working... the board doesn't come with wireless built in so that's a third party problem.

    Thanks for the reply. I'm running a cooler master hyper 212 and I don't think it's a cooling issue. I'll have to check the temps to be sure, though. If it was a cooling issue, wouldn't the adapter show up in the device manager and resume normal operation when the pc is started up after it has been left off over nite?

    I wasn't clear about what the "internet" problem was I was referring to. My internet works as I am using a laptop with wireless connection to post this message since my pc has no connection. I simply meant that I had no internet connection because the wifi adapter was non-operational.

    In the mean time, is there a utility that I can run to verify that the problem is the motherboard instead of springing for a new wireless adapter to rule the adapter out?

    Thanks in advance.

    I think you mean Ethernet adapter and not WiFi as WiFi is wireless technology.

    If the chip was failing due to overheating, then after cooling down it may return to a functioning condition if the chip wasn't permanently damaged. If you have unknown or devices that show up with problems in device manager, then it might be a Windows/BIOS configuration problem. A BIOS reset and update with no special tweaks or overclocking (besides SATA to AHCI/RAID mode) can help verify if it's an internal resource problem... which Windows and the current hardware should have absolutely no problem configuring at boot.

    You can rule out some Windows configuration issue by using a "Live" Linux DVD (Ubuntu, OpenSUSE, or Fedora) which will contain support for the chipset and RealTek ethernet controllers. However the case still remains that if the controller does not show up at all, then the controller is dead and needs to be replaced. Since it's integrated, the entire board goes.

    If you don't want to replace that board, you can buy an PCI or PCIe ethernet card or use a USB ethernet or wireless adapter.
