Windows 10 with VPN software installed cannot detect wireless network

Windows 10, Microsoft’s latest OS offering, has been enticing more and more PC users to upgrade to it. However, some occasional slip-ups have also been noticed enforcing all users to point out fingers at it. No Internet Connectivity issue has hit a massive user-base. We have even seen cases where users have upgraded to Windows 10 and further they were left with no option to connect to the Internet at all. Several have reported that Wi-Fi does not work after upgrading.

One such issue occurs when PC’s with VPN software are unable to detect wireless networks post Windows 10 upgrade. This article lists down all the symptoms, causes, and the possible fixes.

Windows 10 with VPN cannot detect wireless network

The symptoms of this problem are:

  1. Wi-Fi Not Detected

For users who have a Windows 8.1-based computer and also have the VPN (Virtual Private Network) software installed are majorly affected by the problem of No Internet Connectivity. In case such users upgrade their computer to Windows 10 OS, it doesn’t detect the wireless connection.

  1. Restarting computer/Reinstalling Adapter doesn’t help

Restarting the computer or trying to reinstall the wireless network adapter driver might not help in fixing this issue of no internet connectivity on Windows 10. The issue might not be with the adapter; the wireless network adapter would be functioning absolutely fine.

  1. Affects the Wired Ethernet connections

Post upgrading to windows 10, the wired Ethernet connections might also get affected from functioning correctly. It might also affect the connections made through the built-in Ethernet adapter or the USB Ethernet adapter.

What is causing the problem

According to Microsoft, this problem is related to the VPN connections present on the computer which was upgraded to Windows 10 OS. Or we can put it the other way, that if the VPN software was active on the PC during the upgrade, it might lead to this problem where the computer may fail to find the Wi-Fi connection caused by the VPN software. This was just one type of case. However, there are other cases seen where the hardware is not compatible with the Windows 10 OS and it might be the actual cause of the problem where the user is unable to connect to the Internet post upgrading to Windows 10.

“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.”

Let’s see how we can fix this issue with few simple steps and get the Wi-Fi working like before. Here are the steps to fix the No Internet Connectivity Issue on Windows 10.

Word of caution

This word of caution is for the users running older versions of the Cisco VPN client or Sonic Global client, in case of users running any one of these you should uninstall them from your computer before upgrading to Windows 10.

According to Microsoft,

“This issue has been reported when older versions of the Cisco VPN client and the SonicWALL Global VPN client are used. Customers should contact their VPN vendor to upgrade to software that’s supported by Windows 10”.
