Have you ever faced a situation, in where you tried to change your DNS, and you realised, you cant, just because of this issue?

In order to configure tcp/ip you must install and enable a network adapter card.

It must be annoying right?

I had this problem on my Dell Inspiron 14R SE (7420) that was running on Windows 8 64-Bit.

After a few trial and errors, I managed to find the solution.

Please make sure you have already downloaded the latest drivers from Intel Driver Update Utility, if you are on an Intel chip.. , download the suitable one for your computer.

1. Hit Windows key + R, enter devmgmt.msc and press OK.

2. In Device Manager, Scroll down until you see Network Adaptors. Expand it. Now, for my case it is the Intel Centrino Wireless-N 2230.

3. Right Click on Intel(R) Centrino(R) Wireless-N 2230 and click Uninstall, do not tick the box that says 'Delete the Driver software for this Device'. Then, press OK.

4. At this point, you will lose your internet connection already, dont be panic.

5. Go to Uninstall or Change a program in the Control Panel, right click your Intel PROSet/Wireless WiFi Software, click change


6. Based on what you see in the above picture, press Remove. Uninstall everything..

7. After you had done removing, if course you still dont have Internet connection, so what do you do is launch the software that you had downloaded earlier from Intel Driver Update Utility, for my version as of this posting is wireless_15.5.7_e64.exe.

8. Just do the usual installation, click on Next, Next, Next, Typical Installation, Next, and it should install itself. 

9. Once everything is done installing, you should see that you can now reconnect to your WiFi.

10. Try to change your DNS once again, this time, the error should not pop up and you can use your preferred DNS. I would recommend using Google DNS.

Sooo. That's it!

    The error can also be caused from corruption resulting from "duplicate" instances of the same network adapter especially USB WiFi dongles redetected as new hardware if plugged into a different USB port.

    Persistent errors can be fixed downloading the UpdateReadiness tool designed to repair wide ranging problems without obligation to execute an Windows upgrade.

    The download isn't chintzy currently weighing 500+MB to be downloaded while in town instead of AoL at the monastery.

    Server 2012/r2 and Windows 8 - 8.1r2 are repaired best if verified while remaining online:
