Transfer WiFi to a PC using a ESP8266
Just make sure that your PC has a network driver able to read and write data from the UART.
That's a feature that Windows 2000 Server had.
I doubt that Home or Professional editions of Windows come with such a driver.
Windows Server might have that driver.
Linux might have it.
