I was going into my network settings to change the DNS for my ethernet when I noticed an error that I've not seen before: enter image description here

I don't understand what this mean, because my adapter is enabled... which is how I am currently accessing the internet. Any ideas?

  • Are you operating as an administrator? Mar 4, 2015 at 21:50
  • Are you connected via wired or wireless? The controller you have a screenshot of is for a wired controller. Verify you are attempting to access the properties of the controller being used.

You may be able to fix this by uninstalling/re-installing the drivers.
Go into device manager and uninstall Realtek PCIe GBE Family Controller
After it completes uninstallation, go to "Action" in top menu, select "Scan for hardware changes"
Once the controller re-appears in the list, right click and re-install the drivers.
It may be a good idea to download the newest drivers for the controller that pertain to your PC.




Thanks @Cosco Tech for the pointers.

For Intel(R) Centrino(R) Wireless-N 2230 version UNINSTALLING the driver from Device Manager & RESTARTING solved the issue.

  • Great instructions. However, I just did Uninstall and then 'Scan for hardware changes'. I didn't have to restart my laptop.
