In any case I doubt easy is accurate, but it's worth pointing out that the 41C does not have a TCP/IP stack, so even if WiFi h/w was available, (including the equivalent of a driver in MCODE) you still could not do much with it, or maybe you have more ambitious goals in mind. Not trying to rain on your parade, just want to make sure you know how much you are tackling.
