    Internet connection is lost at random times when Windows VPN is active


    I am a seasoned Windows user and software developer 30+ years. I have done a lot of testing to try to figure out this problem but I am at a loss.I'm running Windows 10 on two different computers and the same problem occurs on both of them. I work from home and the firm I work for has an internal network that hosts various resources servers and software. They have a dedicated Windows Server acting as a VPN server for users who need remote access, like me. I launch a Windows VPN client connection on my Windows 10 systems to gain access to the internal network. BUT fairly recently the VPN cli

    No Internet Connection When VPN Is Connected

    This particular issue has been going on for almost a month now. My companies IT department is still trying to figure out the root cause. Below is a list of isolation / troubleshooting i've done.

    Issue: Once connected to the work VPN (successfully) the internet connection on the Windows 10 machine disconnects and does not allow any network traffic.

    OS: Windows 10 Home - Version: 1909 (OS Build 18363.476)

    Computer: Razor Blade 2019

    - Latest drivers installed

    - Latest Windows updates installed

    - System Wide issue

    Troubleshooting / Isolation

    • Cellular Data: Verified the Windows machine can connect to a hotspot and successfully browse the internet. (No VPN involved)

    • Cellular Data + Work VPN: Verified the Windows machine can connect to the hotspot & successfully connect to work VPN and successfully browse the internet.

    • Home WiFi: Verified Windows machine can connect to the home wifi network and successfully browse the internet (No VPN involved)

    • Home WiFi + Work VPN: Verified Windows machine can connect to home WiFi. It can successfully connect to work VPN. However once the work VPN is connected, the home WiFi network indicates (No Internet Access)

    • Ping Test + Work VPN: Verified I can successfully ping (work) websites and even the work VPN URL successfully without any packet loss. However once I go to ping (non-work) related addresses like google.com, apple.com etc. there is packet loss.

    At this point I decided to test my work VPN on my iPhone & Apple Mac.

    • iPhone: Home WiFi + Work VPN: Verified the iPhone successfully connects to home WiFi network and the work VPN and can successfully browse the internet.

    • Mac: Home WiFi + Work VPN: Verified the Mac successfully connects to home WiFi network and the work VPN and can successfully browse the internet.

    Isolated: Only the Windows machine seems to be affected. I even verified this issue occurs on multiple Windows user accounts on the Windows 10 machine.

    - Windows 10 is fully updated to the latest November Windows 10 update and issue persists

    - Deleted and Added the VPN configuration several times and issue persisted.

    Third Party VPN Client Test: Tested with Nord VPN and the Windows machine successfully connected to the home WiFi network & the Nord VPN connection successfully connected to a random server and successfully browsed the internet.

    - Disabled IPV6 on VPN & WiFi network configuration (Per IT Support guidance) and issue persisted

    *Currently updating to Windows 10 Insider Preview 19033.1 (vb_release) to see if this might fix anything pertaining to Windows 10 VPN.

    Thanks for any additional guidance / suggestions / help that the community offers.

    After trying to connect to VPN in Windows 10, internet connection is lost

    After the upgrade from Windows 7 to Windows 10 on m PC everything seemed to work fine, until I tried to establish a VPN connection to my workplace (via the VPN function embedded in Windows). The connection failed with the following error: "The remote connection
    was not made because the name of the remote access server did not resolve." At the same time my internet connection was lost and I could only recover it by restarting Windows. And this happens EVERY time I try to connect the VPN. Internet connection works
    just fine until I try to connect the VPN.

    The funny thing is that on my laptop (upgraded to Windows 10 from Window 7 as well) I can connect the same VPN without any problems and my internet connection works just fine. The difference is that I use wi-fi access on my laptop and ethernet cable on my
    PC.

    Any ideas how to solve the problem?

    I urgently need the VPN on my PC or I will have no other choice but to revert to Windows 7,

    Internet connection is lost at random times when Windows VPN is active

    VPN connected but no internet Windows 10

    Hi there,

    I have to connect to a VPN to work remotely from home and every time I connect to the work VPN, I lose my internet connection. I was advised by the technical team at my job that this should not be the case and they provided me some instructions but doens't
    seem to work.

    Are there any steps available where I can set my computer up to be able to connect to my work VPN but I can still work on my local desktop with my internet connection. Any help, steps provided is greatly appreciated.

    Thanks!
