Why are people recommending putting the Airave behind the router (i.e., connecting the router to the cable modem)? I would assume the reason Sprint suggests connecting the Airave directly to the cable modem is so that the Airave can prioritize phone calls. I imagine most of us would want limited bandwidth to be allocated first to phone calls, then to data.
By putting the Airave behind the router, you don't get that prioritization unless you change the router settings.
Am I missing something?
