If SugarPixel was previously working and now displays these WiFi messages, your router likely needs to be restarted.
Restart your WiFi router
Wait 5 minutes
Unplug SugarPixel and plug it back in
If you use a mesh network or WiFi extenders, restart all nodes as well.
If the issue continues, repeat these steps up to three times.
If this is your first setup — or restarting does not resolve the issue — follow the Home Wifi Advanced/Troubleshooting setup for guest networks.
