With the ConnectOne modules (and the ENC28J60) you do not need the Microchip stack. You connect using either serial (RS232 TTL) or SPI.
Read the ConnectOne AT+i Programmer's Manual. Basically, you communicate with the nano LanReach using AT commands in the same manner as with a modem using the serial interface. It's very simple.
With the ENC28J60, you are working at a lower level and it is far more complicated.
Stick with ConnectOne.
