Some times use my S3 with mobile hotspot to connect work HP3460 laptop if I need to leave house. Lets say Im gone ONE hour. I may have to reconnect my VPN 3 times. Why .... ??? Because my hotspot keeps losing connection, even if only for a second or two .. And then VPN disconnects. I have my laptop sitting on the car backseat and I can hear it moment VPN drops due to mobile hotspot disconnecting. I need to STAY consistently online so this makes for a very poor customer experience. Note: I pay personally for my cell coverage. The laptop is my employers.
