Yes, Did you "forget the network" of your main WIFI signal? And updated firmware to 1.7 as well? Also check and see if your tablet is updated too. I know man.....I felt the same way as well with all the money we spent on this camera.
Hey guys!I was having the same problem until today. I updated my firmware, reset the communication settings, and erase previous nickname........still wouldn't connect. But when I deleted the main wifi connection(my home wifi) on my Ipad, it WORKED......
