In the last 3 months ive tried out 3 different VPN services(paid) and ive noticed with ALL of them that they are acting extremely buggy. So far ive used WiTopia, PureVPN, and now im trying out PIA because of the great reviews it got.

On all 3 vpns, it got to a point that when the VPN was connected, my internet connection would drop completely regardless of the fact the vpn displayed "connected"

This wasnt always the case for example with WiTopia, it was working pretty flawlessly for the first 2 weeks or so, then began acting out.

I also noticed with all VPNs that the kill switch never seems to work with my computer. If the VPN program is running however not connected to a server, I would still have access.

Im not too sure what could be causing this problem. I disabled windows firewall temporarily as I thought it might be blocking but the same problems arise with FW on or off.

Im running Win7, the laptop is a Compaq CQ60 (old laptop) 2.0 GHz, 3 GB RAM, and am using a home wifi connection (if this helps)

Has anyone encountered this problem?
