I got a couple of ESP32-C3s from Adafruit and have been trying to get them to connect to wifi, I've got a Unifi AP setup with a standard WPA2 network, nothing fancy. My setup is an M2 Pro MacBook, latest VSCode / Extension / Node LTS, etc.. and on both devices nothing works. They both seem to run the code fine but any wifi-related stuff seems to fail, just get loads of Additionally they fail to move to the Wifi provisioning step when trying to use the whippersnapper bootloader flashed with esptool, so I'm wondering if they have bad wifi chips or what? |

The Qt Py esp32-c3 is definitely a board we've been testing on. If you are able to flash other samples using Wifi with Arduino or Micropython, you should be able to rule out hardware malfunction. |

I tried with multiple Arduino samples on my windows pc and nothing, while the boards can scan the wifi around, they can't connect to anything, not even my phones hotspot, so I'm rather confused why they can scan and see networks but not connect. I noticed my Access Points caused multiple SSIDs with the same name but disabling all but one still cause the ESPs to not connect. Dunno if I have a bad batch or what now, but clearly it's not a device script issue, or OS issue. |

Adafruit might more magic debugging tips for you. |

Found this thread on the Adafruit forums, seems the C3 is known to have issues and they’re issuing refunds. https://forums.adafruit.com/viewtopic.php?t=202421 And another: https://forums.adafruit.com/viewtopic.php?t=202978 |

This is interesting. I designed my own C3 board that had the same issue. I thought I somehow messed up the uFL antenna connector routing but maybe not :) |

If it’s not just an Adafruit issue maybe it’s an Espressif issue. ¯_(ツ)_/¯ seems the S2 / S3 Are Fine, maybe the C6 is better? It also has wifi 6 so that’s neat |

I had the same problem with a Lilygo TTGO board see: Xinyuan-LilyGO/LilyGo-T-OI-PLUS#4 |
