    LAN adapter vanished

    by rossdorn ·

    Monday night my desktop worked fine, Tuesday morning, no internet connection was possible.
    It is a six year old “self-built” desktop with a ASRock B85M motherboard.
    https://www.asrock.com/mb/Intel/B85M/index.asp

    Two bootable SSDs, one Win7, one Ubuntu, both no longer connect. There no wifi in the house, but none on that computer, only cable Lan. When that cable is plugged into this laptop, it works fine…
    The device manager still shows two adapters for my VPN (which are now also unable to connect to the net), but the third one for Windows has completely disappeared, I uninstalled and reinstalled the Qualcom Driver, no difference.
    I tried to set the BIOS settings to default, but could not find anything in the BIOS setup of the B85M… (?)

    From what I found at Google (duckduck) it may be the Net Card NIT, which I also cannot find on B85M.

    I would appreciate your help with this, thank you.

      Great sleuthing and testing on your part!

      1. “both no longer connect.”
      2. “When that cable is plugged into this laptop, it works fine”
      3. And your other tests…

      At the shop we advise to install a 10 to 20 buck network card given the story and your testing. Testing a motherboard is not too hard as we:
      a. Use BIOS default values (see motherboard manual.)
      b. Boot a few LIVE LINUX distros (I use Tails and either Puppy, Mint or Ubuntu.)

      I don’t suggest those USB to Ethernet over a card solution due to sometimes the USB version is finicky.

      You did great here and almost did everything I would if the machine landed in my lap (ouch?)

        As I am at presnt in Tokyo and do not rally speak Japanese, I will have to look at amazon for a “network card” (they have pages in english)

        What exactly am I looking, I only have a vage idea. Could you post a link to a product like that?
        It ounds like something that I plug my cable into, and then…. uplug it into a usb socket???

          I prefer a PCIe x1 card.

          But can’t tell if your built PC has that slot open.

          Remember that Ethernet PCIe x1 cards are both fungible and plentiful here (USA and Canada) and I’ve yet to get a bad one.

          https://smile.amazon.com/TP-Link-1000Mbps-Gigabit-Ethernet-supported/dp/B003CFATNI/ is currently ranked #3 in best sellers here. I have no qualms about this card.

          ASRock B85M and PCie

          I remember researching these PCie cards while ago, and found that the ASrock B85M does not have a slot for them…

          Am I wrong?

          Link. Is this your board?

          “You can use a PCIe x1 card, or a PCIe x4 card in a PCIe x16 slot. They work fine. So if you think you are short of PCI-e slots, you may not be. A shorter PCIe card works fine in a longer slot.Sep 7, 2015”

          These four are the relevant slots?

          Sorry had to take the dog out….

          Yes, that Board looks similar. (I have noticed that there are about a dozen different B85M, depending which country you are in.)
          But mine has these same four slots, in the one most at the middle of the board is the NVidia card, the next two are two close to the GPU to be used, only the one at the rim of the motherboard looks usable. And that is almost totally against the bottom of the case, so the only direction from the slot that there is any space at all is straight up… So the amazon sample you showed me, would not fit ?? Can they be adapted to be fixated?

          Later: I have ordered one of these… Other than install the driver, that can be downloaded from realtec, is there anything else that needs to be done?

          So far.

          I’ve never had an issue with fit on these small PCIe network cards. As to which board you actually have, all the B85M boards I looked at had two PCIe slots.

          I have order the card, and will let yopu know, if it was a success.
          Will the card just need to be inserted, like a memory stick, oder is there some installing, other than the driver installation, like cable, necessary?

          These have been plug and play. The usual 10/100/1000 cards don’t need drivers to be hunted down (Windows 10.)

          W7.

          by rproffitt ·

          In reply to Oh, Lord…

          “Windows 7 32/64bit” is listed so while it may not be as easy as W10 and these cards, if you need a driver, it will be up at TP Link’s site.
