I picked up an RT-AC3200 in April to replace my old RT-N16 running Tomato. Since I swapped routers I've noticed that my iPhone often experiences connection issues. The wifi stays connected, but I cannot access anything on the LAN or WAN. My wife says she has seen the same on her Macbook, though I haven't seen this on my Macbook Air. I'm running the latest firmware (3.0.0.4.378_7838) and have experienced the issue with Smart Connect both enabled and disabled. I use the same SSID for all APs....
