Hi Philip,
Not exactly, but sometimes the precursor data service (CDPD) would "rehome" at curious intervals (and in my case to the incorrect switch), and that's something the NOC (Net Ops Center) can be asked (via tech support) to undo when it happens. Even so you'll probably still need that power cycle to consummate the deal, so glad you have a smart power system that does that. Curious that a data service has this fatal weakness -- we really are still out at the hem of the coattails.
Cheers,
John

> No, The modems don't require a daily resetting of the devices. An occasional power-cycling of the modem wouldn't hurt but should not be required. If you are having occasional issues with the strength of the signal (RSSI - Receive Signal Strength Indicator being low (higher negative value)), then we would need to determine what the issue is one a case-by-case basis. You also want to watch the EC/IO (a measure of energy (interference)) as well. A directional antenna should provide a better signal. Whether the device has to be reset depends on its recovery once the connection has been re-established.
