Hello,
I'm trying to use an arduino mega and an ethernet shield to with the mqtt examples and the Adafruit IO examples, though I encounter errors when doing so. For the IO example, I keep receiving "connecting......" in the serial monitor and "malformed username / key" error for the mqtt example. Does only the adafruit ethernet shield work for this?

Re: hardware compatibility
Which ethernet shield are you using? Could you provide a link to the product URL?
