I have an original airave and was updated to the airvana, but had nothing but issues with the airvana and actually went back to the original airave. The only differences is that the airvana can handle data too, not only phone calls and texts, but I got so fed up with dropped calls and the system losing signal, I went back to the airave and haven't had issues since. I spoke with tech support almost daily for a couple of weeks and they kept updating software, etc, and finally the device remained connected (no amber lights on it) yet it would still drop calls out of the blue. I haven't heard of anyone else having these issues, everyone loves theirs, so maybe I just got a faulty device. And I completely agree with quick99 above, do not put it between the modem and router, the paperwork says to, but tech support said it doesn't make a difference and if the airvana gets borked, it won't impact your router. Good luck!
