Wireshark is showing the above, last night the VPN dropped out could this be the cause, below is Air VPN logs, I have reinstalled windows.

Hello!

Yes, that can be the cause: the logs show a high packet loss. If the problem persists, please try a TCP connection, or tune your OpenVPN client, for example with mssfix. Please see here for details:

https://airvpn.org/index.php?option=com_kunena&func=view&catid=3&id=4853&limit=6&limitstart=12&Itemid=142#4957

If you suffer significant performance loss with a TCP connection, then it's worth trying the above on an UDP connection. You can insert the directives directly in the .ovpn configuration file (anywhere). In this case you will have to use OpenVPN, not the Air client.

Please feel free to keep us updated.

Kind regards
