I am also having issues using my WiFi calling. I've been working with Netgear for almost 2 months now, and it still isn't fixed. My Modem/Router came with firmware V1.02.10, and after about a month of "trying things", they told me there was a firmware upgrade and that my ISP needed to push it to my modem. After a couple of weeks, my ISP, Grande Communications, pushed it(V3.01.14), and now I have more issues than I had before. After working with Netgear again, I was told that this firmware version was ONLY for Comcast. So, here I sit, waiting for a fix or a modem/router that works.
