What adapter did you bought and what kind of setup you made? I'm actually using an RJ45 cable and it is s working fine. I don't believe there's a hardware problem as the connections are made.

My solution by now was to place a powerline near the projector and plug a RJ45 cable to it. It is now more stable at least. Wi-Fi in the projector itself is a disaster at this point.
I suggest everyone to give feedback using the app Mi Home. It's a Mijia product, if everyone give feedback maybe we can reach our goal. Well, it's the interested of Xiaomi either.

It seems to be firmware because there are periods everything is working perfectly fine, however we know the connection will stop anytime which is terrible if we are streaming or watching live TV.

Contacted Xiaomi Spain. They asked me to reset the projector. After doing that twice it keeps the same. WiFi is lost at some point and the WiFi speeds terrible so far.

Bought a Mijia Projector 2 Pro and and I'm also having WiFi issues. WiFi is lost constantly, Internet speeds lowered with no reason. It is unbelievable that Xiaomi doesn't give any support for something that cost more than five hundred euros.
