I recently purchased a MiFi to be used while commuting, but apparently the AutoOn doesn't really work as expected.
In less than a week I bursted £16 pound credit, when I was supposed to pay £0.2 per each 20Mb. As I did not downloaded 1.6GB of traffic, but I don't have time to complain I wonder whether there is some way or some software to control at what time my laptop use a specific network.
By doing this, even though the MiFi will remain active, no network will be connected and I won't be charged (though it is also strange I have made traffic with the laptop off).
Look forward to hearing from you. Andrea
