Why can't I use wifi?

[Troy Mitchell]

I used to use an onboard PCB and everything worked fine, but when I tried using a ceramic antenna, things started to go south.
I can't connect to the sta or use wifi mesh.

Does it still work without the antenna?

It seems not to work, infinite reset

Did you solder it the right way around? Dot indicates the feeding point, so it should be towards the ESP32.

Of course. And I tried two different ceramic antennas ... but same...
I don't know why.

No clue. Possibly an impedance mismatch somewhere; you'd need a VNA and the knowledge how to use it to find and correct that issue, though.
