I had a problem with Windows 10 remaining connected to VyprVPN (I am connecting to Australian servers in Australia) but experienced numerous intermittent failures when trying to access websites / download mail etc.
Disconnecting then reconnecting via the GUI would sometimes help me get back on the internet but not for long and not always. With the vpn still showing as connected if access to websites dropped out, sometimes just coming back after a few minutes it would start working again without doing anything.
I was using the opnvpn protocol so I tried the Chameleon protocol but had the same problems. This was very annoying and I was on the 3 day trial and about to pull out.
I switched to the l2tp/IPsec protocol and I have not experienced this problem since. (2 full days now)
The history of my machine is originally built with windows 8 then upgraded to Windows 10 a few months ago. No vpn software had ever been installed until 4 days ago when I installed the latest version of VyprVPN.
So switching to L2TP/IPsec and not using OpenVPN or Chameleon is working for me on Windows 10.
I've got the other issue some Windows 10 users have when starting their systems - "The VyprVPN service could not be contacted. Would you like to attempt to start the service?" but that's not for this thread! details here
