Fix No Wi-Fi Available After Windows 10 Upgrade Issue, Here’s How

As more and more PC users roll onto Microsoft’s latest OS offering, Windows 10, occasional slip ups within the operating system are bound to be pointed at. One such problem circling some in the massive user-base happens to be about dreaded broken Wi-Fi, but luckily there is a quick yet nerdy solution for fixing this issue in a jiffy! We show you how, right here.
To explain the issue at hand in a bit more detail, the problem is surfacing on machines that were upgraded from Windows 7 or 8.1 to Windows 10. Apparently if you had a old VPN client, specifically from Cisco, configured on your older Windows setup, Microsoft is certain that piece of software is what is causing the issue on Windows 10, and no amount of reboots or safe-mode investigations will fix the problem at hand.

How will you know if this is exactly what’s the issue on your PC? Well, if after the upgrade to Windows 10, no wireless networks are available to connect to even though wireless networks are available in range, and the Wi-Fi adapter underneath appears to be working with compatible drivers installed, if this is the case, reinstalling the driver or rebooting your PC won’t fix the problem.
As Microsoft puts it, “This issue may occur if older VPN software is installed on Windows 8.1 and is present during the upgrade to Windows 10. Older software versions contain a Filter Driver (the Deterministic Network Enhancer) which is not properly upgraded, leading to the issue.”
Fancy explanation aside, here’s how you can fix all that and get Wi-Fi working again in Windows 10:
Step 1: To begin, launch Command Prompt as Admin. To do this, simply right click the Start button and select Command Prompt (Admin) from the menu.

Step 2: Enter the following command and hit the Enter key:
reg delete HKCR\CLSID\{988248f3-a1ad-49bf-9170-676cbbc36ba3} /va /f

Step 3: Now enter this command, and press Enter once more:
netcfg -v -u dni_dne

Preferably, you should restart your computer and check back with your Wi-Fi settings. All networks around you should now be visible and you should be able to connect to them easily.
We would like to take this moment to issue a word of caution for users running older versions of the Cisco VPN client or Sonic Global client. If you are running any one of these, and are planning on upgrading to Windows 10, you should uninstall them before proceeding.
Hopefully Microsoft will be issuing a more passionate warning in the next few days regarding this breakage before more users find themselves caught in this mess.
