Realtek Ethernet Controller Driver: The Realtek Network Controller was not found

    General discussion

  • Hey everyone, just built my first computer, and long story short getting the following error:

    Realtek Network Controller was not found. If Deep Sleep Mode is enabled please plus the cable.

    I've tried multiple compatibility methods, still won't recognize and install - got the drivers from my motherboard's website, which says compatible with Windows 8 x64. Can't find my Ethernet adapter in my Device Manager at all either (have my wireless USB adapter and a MS Kernel Debug Network Adapter listed, no Unknown Devices.

    Anyone run into these issues and find a fix? I read somewhere to clear my CMOS but I don't see that option in my BIOS.

    I really want to get this fixed; having a ton of other issues but I want to get the hardware all down and set so any help would be greatly appreciated. Thanks again

  • But you have installed the driver from the motherboard vendor?

    Have you checked in bios so the nic is not disabled?

  • I installed the drivers from the disk, after removing the ones I got from here:

    (won't let me copy and paste the url:)

     didn't do the Chipset one at all, Onboard Audio works fine, USB Controller installed I think (I wired something wrong, gotta fix that still), Serial ATA I'm skipping. I'm getting my errors from the original post with the On Board LAN Win 8 Drivers for version 8.003.0730.2012. My network adapter says enabled but I'll check again. Thanks

    Shows as updated. I'm really lost, trying to lookup solutions; other people seem to get this but their Realtek is showing in Device Manager.

  • Try to install the chipset drivers also, sometimes devices are on a "shared bus" so the bus will need a driver Before the nic device will get detected.

  • I just installed the chipset drivers too and rebooted, doublechecked it was enabled in BIOS; still not appearing / getting the same error if I try to install

    Its weird cause if I run it again it thinks it's installed (I can repair and remove). I'll reach out to Biostar but if you can think of anything else. Thanks again man

  • Hi,

    I also checked the Realtek website and found there was not Windows 8 driver for Realtek network adapter. Please try the one for Windows 7 with compatibility mode and see if it works:

    As the network adapter could not be found in Device Manager, please also check it with Biostar.
