for anyone using any mifi device that has throttle fix or not you should all know this,i sent this to a member today in pm and thought it should be in the forum also.
"keep in mind that data packet timers will cause the device to become very slow after periods of non use if you experience this simply remove battery for a few seconds and replace that will restart that timer."

it is easy to confuse this with throttle,the device uses data packet timers for several reasons but the result can be a state of "idol" for your device. but when this occurs upon reboot the device's function is at normal speed again.
