Hello everyone, I would like to share an important experience with you. For those people who have problems connecting their robot to the wifi router, here is a tip: I found out that almost none of the xiaomi systems can be connected to a router that contains non-alphanumeric characters in the router name. Example: jtc-5478/2.4Ghz as much as I understood from google, the dot, dash and possibly the slash "/" are in the wrong place here. by chance, I read it once when reconfiguring my humidifier (also from xiaomi). so if it doesn't work, change the wifi name ;D - attention! all devices already on the wifi must be given the password again!
