It depends on the protocol, as you said. Check in your router what kind of authentication your WiFi uses, and adapt the WiFi connection to that.

If your home network, for some weird reason, uses WPA2 Enterprise, the ESP32 WiFiClientSecure module should be the one you go for: https://github.com/espressif/arduino-esp32/blob/master/libraries/WiFiClientSecure/examples/WiFiClientSecureEnterprise/WiFiClientSecureEnterprise.ino

@jcabad100 For me the noise happens when

1. The FIRE is turned on and I press the power button (the one next to the USB port)
2. The FIRE is being programmed by the Arduino SDK and switches into the download mode. It lasts maybe 2, 3 seconds in total and always disappears

The reason for this, I guess, is that the speaker pin (GPIO25) is sitting right next to the RST pin, and most likely the lines are interfering.

As for the magnetic dock not providing USB connection... There are two data pins exposed, so I suppose USB communication should be possible up until the GO bottom module. However they're connected to GPIO21 and 22 as I2C pins.

I've got a response on AliExpress from Jimmy Lai, confirming the issue with the button press making a noise on the speaker, and recommended adding the following snippet:

//disable the speaker noise
dacWrite(25, 0);

I'll check and see how it works.

I've returned them and ordered from the official store... And the same model was delivered, with MPU6050+MAG3110, the same screeching of the speaker when I press the power button, and to top it all off, the bottom boards seem to be swollen as well (the bit where the battery is connected to the PCB is pushed and warped upwards, making stacking quite difficult and in some cases, impossible).

I'm really feeling let down by the quality of the product to be frank.

I purchased two FIRE kits from an Amazon UK vendor. However both units have some weird QC issues (on one two of the top buttons are not exactly "clicky" but more mushy, like if there was an issue with the buttons, and the others' LED bar diffusers are not neatly cut, there's a large-ish gap on it), and to top that off... Whenever I press the side button (power/restart) while the FIRE is on, the speaker within produces a quite loud white noise. Oh also, these are the older model with MPU6050+MAG3110 instead of MPU9250.

Are these symptoms normal, or should I return the units?
