Using the AP method is the easiest. This app sucks if you cannot get the device into AP mode like the liectroux c30b robotic vacuum. I have purchased and installed a new WiFi 6 router that has the latest firmware for the AX standard. Routers have nothing to do with the flaw in this software. If there is a requirement please post the requirement as I have searched and cannot find any required specifications or settings to have this app actually work properly
