After trying everything I got from the manufacturer, and from other various online sources, the Robot was still unable to find the Wifi.
I returned.
And I bought a different one, different maker, even cheaper, 114 vs 129. And It just works.
If it takes longer to make it working than it takes buying online, there's already something wrong with it.
And if the guy who runs a particle accelerator cannot make it working, maybe maybe sending it back was not a wrong decision after all.....
