will the sonic hotspot automatically wake up:

(a) when the charger is plugged in, if its in the "wifi deep sleep" after the wifi-on-battery idle timeout has passed

or (b) when the charger is plugged in after being left powered up on battery and the battery has completely discharged

I've already discounted the cheaper t-mobile hotspot because it can't pass either of those requirements..

I'm trying to find a hotspot that will be 'hands off' when its connected to the car accessory power, havent found anything other than the now lowly mifi 2200s! its frustrating that so many hotspots need a power button push in these circumstances.
