I have my Apple Sports Watch since August last year with all available OS’es (currently the latest beta) and it works fine apart from one thing. When out of BT range it does not connect to my Wi-Fi. Did all the things you should do like forgetting WiFi networks, restarting, resetting, it will only connect to WiFi when I disable BT and only the first couple of hours. The next day it will not connect anymore to WiFi when out or BT range. I have separate 2.4 and 5 GHz networks, my Wi-Fi coverage is done with 1 Airport Extreme and 3 Airport Expresses and my iPhone 6Plus never loses WiFi connection (2.4) but the Watch does. What am I doing wrong? Please help me out.
