Before the Viastat switch from Exede customer svc gave me a link so I could view my daily data usage. It helped to see where it was going. We were having issues with our data just being eaten up!. Anyone know how to get to this now, since the link is no longer available?
Glasswire is free for the basic version, which has all you need to monitor usage on each Windows computer. The best way to monitor data usage is to invest in a decent router with traffic monitoring capabilities. This way you can see all data used by your local network, by which device, how much, what applications, and when it was used.
