I purchased two nest Smoke detectors today and I could not get the second one set up for the life of me. After an hour and a half on the phone with Nest support, they said that my router is not giving out and IPv6 connection. My router supports IPv6 as it is a Netgear nighthawk AC 3200. I tried to set it up on my own following online tutorials with no luck. I called my ISP and they were absolutely worthless. Can anyone out there help me with this issue?
