During the few months I've been using various AirVPN USA servers to connect my Mac notebook via Tunnelblick software from various Starbucks stores' WiFi, I've noticed a definite correlation between available bandwidth and the frequency of random disconnects from the VPN. This is based on observations of how many devices are being used in the store, SpeedTest.net results, both on and off the VPN, and observing the log files.
It would help me greatly to know just how much bandwidth I need in order to connect through the VPN and avoid these random disconnects.
Just in case there is something going on that I don't understand (maybe a timeout of the VPN server I'm using? I do make sure I use the lowest latency, highest bandwidth server by checking the Status section of the website before getting down to serious work), I'm attaching the log of the latest disconnect I experienced.
