    Ethernet driver can't be reinstalled

    I was working normally using cable connection (no wifi available), when suddenly the internet was disconnected. Earlier when the first time I plugged the cable (about 4 hours before), the icon keep switching for a few moments between connected (monitor icon on taskbar) and disconnected (empty wifi icon). Windows diagnose said DNS is not responding. I tried ipconfig /release and /renew, etc but not working. I decided to uninstall the driver (in the past this worked for me), but when I reinstalled the driver, the error message seen in the bottom left of the attached image.

    I looked for a solution, one is by setting the system events broker to auto, but I can't change it (top right image). I also checked the bios, but I can't find any option related to LAN card.

    I need a fix because my current long term option to connect to the internet is using cable. My laptop is ASUS N46VZ

    Thank you for any help and I'm really sorry for terrible english.

    I had a similar problem when upgrading from W7 to W10. The network adapter worked fine until the final reboot of the W10 upgrade, then it failed to connect.

    Before getting to the fix that worked for me note that Ethernet cables are not very robust at all. They can be damaged easily by one too many yanks or being tripped over. And router ports can go bad too so consider swapping cables and ports.

    This does often work, but because today's computers don't power off completely when shutdown (they go into standby), sometimes it is necessary to completely remove power to release any settings (including network settings) the ATX required +5Vsb voltage is holding. For a PC, this means unplugging from the wall or setting the PSU's master power switch, if it has one, to off for 15 - 30 seconds. For a notebook, this means unplugging the charger and removing the battery. This "cold" boot process is often necessary when uninstalling and reinstalling network drivers.

    From another computer I had to visit the failed computer's website and got the latest network drivers for and saved them to a thumb drive. Then back on the failed computer, I uninstalled the current drivers and installed the new drivers from the thumbdrive, shutdown and powered off completely, waited 15 seconds, connected power and booted. Windows saw "new hardware" and installed the new drivers and immediately connected to my network.
