Win10: no internet connection...

[nio101]

Hello,

Since I've upgraded to windows 10, I can't use my VPN anymore. Viscosity connects to the VPN, but I can't access any website, windows says "no internet connection", and when deconnecting/quitting viscosity, I can't recover my internet connection, I have to close/open my windows session.
I've uninstalled/reinstalled viscosity to ensure having the good version/driver (saw that in other posts about windows 10).

Works well under windows 8.1.

Here is the log file:

The only thing I can found is: "ROUTE: route addition failed using CreateIpForwardEntry: L'objet existe déjà. [status=5010 if_index=4]"
"L'object existe déjà" means "the object already exists" in french (my windows localization).

Thanks for your help.

Nicolas.

Hi Nicolas,

Please first try disconnecting any connections and restarting your PC. Hopefully this will clean up everything and resolve the problem. If it does not, once connected, could you please post a copy of your ipconfig and route table. To get these:

Right click the Start button and select Command Prompt.
Type in 'route print' without quotes and press Enter, take a copy of this.
Then type in 'ipconfig -all' without quotes and press Enter, take a copy of this.

Post both of these up, or if you prefer, you can email them to us at https://www.sparklabs.com/support/#contact

Hi Nicolas,

Are you able to ping websites once connected? Please try typing the following into Command Prompt:

ping 8.8.8.8

Nope, can't ping any website... : /

Hi Nicolas,

At this point I would recommend contacting your VPN Provider to see if they have an alternative configuration you can try.

But the same configuration, with Viscosity, is working under windows 8.1, and was working on the same machine before the windows 10 upgrade !?!

Got it:
Going to the network adapter config and disabling everything except tcpip v4 did the trick.

It seems that upgrading to windows 10 resets this kind of configuration.

Hopes this will help others.
