I’m guessing other WiFi enabled devices in your home are connecting just fine. Sometimes when I run into a problem with one device I do a hard reboot to the modem, router, and any switches in between. This insures and fresh start. Follow the directions to add the timer to your network and wait for any firmware updates.

Dear customer,

Please try close all your other app opened in the backstage. And reboot your smart phone. Then do this installation process agian.

Also, could you please let us know your smart phone type?

Thanks,
Netro Support
