+Now connect via Wifi and change the network hardware to "Generic W5500". If the W5500 hwardware isn't detected, Wifi is used as a fallback.<br>
 Note: Encrypted MQTT is only available for Wifi and LAN8720 modules, W5x00 modules don't support encryption 
 (that leaves Olimex, WT32-ETH01 and M5Stack PoESP32 Unit if encryption is desired). If encryption is needed, Olimex
 is the easiest option, since it has USB for flashing onboard.
