Is there a software utility which recognizes which wireless network is connected to internet and can automatically switch to it? Namely, I have 2 internet connections. If one goes down, I want computer to automatically disconnect from it and connect to back-up wireless network. As I live in rural area, primary internet frequently goes down overnight. Chances are, back-up connection will be working. I want a utility which will automatically switch to it so I do not lose data transmitted to me while connection is down and I was asleep, without knowing I had to switch to back-up.
