If a VPN might be in your future, here is an article that may/may not be of help. I found all the data to be a bit confusing, and to be more useful the headings need to be repeated every 5 lines or so in order for one to know what he/she is looking at in all the details. When on a public wifi network I do use a VPN. This way, I don't have to worry about someone 'listening' in on my wifi transmissions.
