I'm not one of the original parties to this conversation, but I, too, seem to have semi-random lock-ups of my U620L. Doesn't matter if I'm attached to my laptop (though it seems that it holds up better) or to the current travel router I'm using in a Road Warrior configuration. Originally, I thought maybe a brownout on the USB rails- but that's not the case. Measured voltages are within USB specifications and above 5v slightly (Instead of low). Getting hard-hangs with the device that require being powered off and back on again (basically the same story as the Pepwave reset of the device as described in the original post). All in all, I have a sinking feeling that the devices are dodgy or the SIM is. Couldn't tell you which. As it stands, I'd been using hotel internet recently (which kind of defeats the purpose of the device and my 80+ GB pre-pay on the account...) and had that go down which prompted me to try, yet again, with the device, with the predictable result of it going down more often than a wh*re on Harry Hines Blvd in Dallas.whe I'd like to know what's going on. That way I can order one from you lot instead of the third party supplier and at least get stable. The device itself when it works is like a dream and is the best one you've contracted out to suppliers for yet. But...if it's not able to stay up...well? It's worse than the original LTE unit from rollout that I finally replaced this year which was an odd beast in and of itself, really.
