    Task Manager: disappearing network adapters after a while


    As you can see, I've just opened the task manager, showing my network cards and their usage. This is what everyone would expect.

    But, there's something that's getting annoying. After a while probably after a hibernation or a network disable/enable, some networks vanish from the list.

    What's also weird is that if the interface manages to re-appear on the list, then I would see the main WiFi adapter traffic on a random interface.

    For instance, my main WiFi traffic shows up on a VMware interface, which in some cases could be the only interface that shows in the task manager. Even if that interface shouldn't get any traffic i.e. no VMs running.

    To trigger this particular example, I just had to disable a network interface and re enable it; WITHOUT closing the task manager.


    After killing the task manager and reopening it, the proper list of interfaces shows up and the traffic shows fine.

    I would say it's a minor annoyance but... It's a bug.

    This happened since the betas of Windows 10 I've tried.

    :)

    Wireless adapter not found in Device Manager

    I ran the Lenovo Solution Center. Network Adapter was not listed in the hardware scanned. Not sure if there is a separate listing for that normally or not.

    Ever since I ran a power cycle the adapter has not appeared in the Device Manager.

    Does anyone believe removing the adapter and putting it back would solve the issue? I would rather not open my computer if there is little chance of it solving the issue. I am a complete novice doing this.

    Not sure if this is relevant but in my Network Adapter in Device Manager there was "Microsoft Kernel Debug Network Adapter". It has since disappeared.

  4. Task Manager: disappearing network adapters after a while

    Wifi adapter completely disappeared, not listed in Device Manager

    I'm asking this question not for myself but for anyone who might run into the same problem as me in the future, to save them a lot of time and possibly panic.

    I had a BSOD (an undiagnosed graphics issue that is triggered by Skype conference calls). When I rebooted, my wifi adapter had completely disappeared (a Qualcomm Atheros QCA61x4A; the computer is a Lenovo Yoga 710-14IKB). The network troubleshooter couldn't bring it back and it had completely disappeared from Device Manager. I plugged in an ethernet adapter and tried downloading and twice reinstalling the driver and then rebooting, but that didn't work. I ran "DISM /Online /Cleanup-Image /RestoreHealth" and then "sfc /scannow" in an adminstrator PowerShell, but still no joy. I then booted into MX Linux from a USB stick, but that couldn't see the wireless adapter either. By this point I was convinced that the BSOD had killed the wireless adapter hardware, but I tried one more thing. I rebooted into the UEFI settings and looked to see whether the adapter was listed as enabled there. Apparently it was, so I changed nothing and then selected "save and exit". When Windows started up again, the adapter was working. I then tried rebooting into MX Linux and the adapter was working there too.

    Which of the steps I took is most likely to have resolved the problem? Was it when I opened the UEFI settings and saved them without changing them?
