Until my CS arrives I'm using my Sony Xperia Z5 with the RC and Spark. During first testing yesterday I had the Wifi connection drop a few times in a short period. My phone is always connected to my house Wifi network and set to connect automatically when I'm home. When my Spark disconnected from Wifi I noticed my phone had reconnected to the house network. Could this be the cause of the Spark disconnecting? I'm guessing this will not be a problem out in the field.
