SMCCLOUD, i'm glad to hear that yours is up an running. I can get the Airvana working when connecting directly to the cable modem. Unfortunately when I use the cable modem-->router-->airvana setup I get blinking mobile amber light. I'm using Trendnet TEW652BRP.
Working hooked up behind my other router. Now to just wait for a firmware update to allow me to actually block other people in my apartment building.
I will do that tonight. Right now I have it hooked up in front of my other router but I will be redoing my network tonight as I reinstall my home server (Amahi).
I just got a 3G Airvana to replace my old Samsung Airave. Unfortunately for me, I am part of a broadband study through http://samknows.com/ (FCC comissioned) and they provided me with a router that has "special sauce" inside it. According to SamKnows all my traffic is supposed to go through the router they provided. Can I hook the 3G Airvana behind it and make it work or do I have to hook it up in front of the router I'm using now? I can post a diagram if needed.
