DIAGNOSIS The Opal 2.0's smart setup can be finicky, especially on crowded home networks or with certain router settings. The most common hang-up is during the phone-to-machine handoff.
FIX 1) On your phone, forget the "Opal_2.0_XXXX" network in your WiFi settings. 2) Power cycle the Opal: unplug it, wait 30 seconds, plug it back in. 3) Put your phone into Airplane Mode, then turn JUST WiFi back on. This forces your phone to use WiFi for the connection. 4) Open the GE Appliances app and start the setup process again. When it asks, make sure you grant location permissions—the phone needs this to find Bluetooth devices. 5) Be patient on the final step; the machine joining your home network can take a solid 60-90 seconds.
IF THAT DIDN'T WORK Try connecting it to a 2.4 GHz network band only. If your router combines 2.4 and 5 GHz into one name (SSID), temporarily disable the 5 GHz band in your router settings during setup. The Opal doesn't play nice with dual-band networks under one name.
HEADS UP The smart features are mostly for scheduling and notifications. The ice maker works perfectly fine without being connected to the app, so don't stress if you decide to skip the WiFi hassle for now.
