Actually. they have both been flashed to the latest firmware, (which is the same) and all
chips match with respect to the numbers printed on them, but it is entirely possible the
minor components could be of slightly different tolerances, or the modems could have
slightly different design differences not easily noticeable to the eye. The printed
revision number of the PCB is the same on both modems though. Nonetheless, connect rates
can, and do vary quite often between different brands, models, etc. even if nothing is
wrong with the drivers or configuration.
