    Ethernet Adaptor disconnecting regularly

    I recently reinstalled Windows 10 and started having issues with my Ethernet adaptor. Periodically my internet connection just stops and then returns after about 5 seconds. While watching the Ethernet performance tab on the Task Manager, when the issue happens the tab automatically switches to CPU Performance. Clicking the Ethernet item does nothing until the issue stops happening the dot beside the Ethernet is white as well. I've looked for updates and reinstalled my Ethernet adaptor Killer E2400. The issue doesn't generate any problem report. Please help.

  2. Ethernet disconnects regularly Windows 10


    Computer is connected to internet via ethernet cable. Regularly i get icon that i have no ethernet connection. I unplug ethernet cable and re plug in and all is ok. I do not lose internet connection when using wireless.

    Currently have ethernet connected to ethernet over power adapters, but issue has occurred even when i am connected direct to mode.

    I need to move computer to far end of house with terrible WIFI so will connect via ethernet over power

    Is there a simple fix or do i have to be a Window guru to know what I'm doing?

  3. Constantly disconnecting with ethernet cable


    Thank you for keeping us posted on the status of the issue.

    I suggest you to check if rolling back the Ethernet driver helps to resolve the issue. Follow the below steps.

    • First of all, Press Windows logo + R from keyboard. It will open
    • Now type devmgmt.msc and press Enter to open Device Manager.
    • You will see all the device list of your PC. Expand Network Adapters
    Rollback driver

    Double click on your Ethernet driver in Device Manager. Then Click on
    Driver tab and select Rollback.

    Important: If your drive is performing well and there is no error, Rollback driver button will be grayed out as an option.

    If it still does not help, I suggest you to reinstall the drivers for the Ethernet driver and check if it helps to resolve the issue.

    Note: Once you uninstall the drivers the Ethernet adapter device will be disabled and you won’t be able to connect to internet. So it is advisable to keep all the installer files as a back up in your hard drive.

    Write to us with the results for further assistance.

    Thank You.

    Wifi Adaptor and Ethernet not working

    Neither my Wifi Adaptor nor my Ethernet can connect to the internet. When I enable the Wifi Adaptor, it will connect to the internet for a brief second, before auto-disabling itself again. The same thing happens for the Ethernet connection. I have tried
    restarting my desktop, uninstalling both the wifi adaptor as well as the ethernet connector device, typing all sorts of random codes to reset (idk what, but pretty much everything on the net). Also, it's odd but my wifi adaptor and ethernet does not disable
    itself UNTIL the moment my computer connects to the wifi. If not connected to the wifi, I am able to see the wifis in the surrounding areas (of course it immediately switches off when I connect to my home wifi).

    I am using Qualcomm Atheros AR9485 802. 11b|g|n Wifi Adaptor and a Realtek PCLe GBE Family Controller. My computer is a ACPI x4-based PC
