My ZTE zmax pro was automatically connecting to my home wifi network, and any other saved networks, when I used a Comcast modem/router. When I rebooted my phone at home, or when I returned home with my phone from being away from my home wifi network, my phone always recognized and automatically connected to WiFi again. Since I bought my own Arris modem/router two days ago, my phone forgets my wifi network each time I reboot it or leave home and return. The network is "saved," but each time I come home I have to go to my settings, tap the network name, and tap "connect" again. I can't find a place in the ZTE phone settings to automatically connect to WiFi, and I never needed to while I used the Comcast modem. My laptop is not having a problem - if I take it out of range, it automatically connects when I return.
