Problems with the device’s memory, NVRAM or PRAM. One of the main pieces that every Mac includes is the volatile random access memory (NVRAM) and the random access memory (PRAM), as these pieces are an essential component without which the device does not work. It is possible that there are some problems with these pieces of hardware that cause the Wi-Fi to not connect. The basic solution to these problems is to reset these parts of the device, and then the problem will be solved and the connection to the network will be restored.
