Aircard 770S Intermittently Stops Connecting

Hi There, I have this Aircard 770S running on a houseboat for remote power monitoring of the solar system etc. when I'm away.  I've noticed that once in awhile, the Aircard will stop communicating requiring you manually power on the device to get it working again.  The firmware seems quite old (SWI9X15C_01.03.06.10 (Build Date: 12/18/12) but the admin interface (via web browser) implies there are no other firmware updates available.   I've read on these forums that some folks have said you can run this device w/o a battery so I'm tempted to put it on a mechanical power timer with the battery removed to force a power cycle once a day.  Just wondering if anyone has seen behaviour like this and if a subsequent firmware update may have resolved this.

  • By the way, AT&T has responded to my question about why this device is reporting there is no firmware update available.   Is there a way to update firmware on this device via a USB cable or some alternate to AT&T's Firmware Over The Air (FOTA) mechanism?  I know this is an older device but it's kind of surprising I can't at least get the latest firmware that was released a few years ago.  Other than an occasional "hang" condition where I have to power cycle the device, it seems to work pretty well.
