I'm not and I never was concerned. I know I would never get great speeds on EV-DO. I knew wifi would always be my data source of choice since I have wideband internet service. I think the confusion stemmed from an earlier comment by Rukin1, which I replied to and it snowballed from there. Granted I'm not an expert in any way about how the Airave works. I just know it works for me in my home as I have spotty voice/text service at best without it. I simply offered some advice based on my experience with the device (wait a while, the Airave should settle down & become reliable again).
That, of course, brought on some side-bar issues which lead us to here.
