hello Nick, It would indeed be interesting to see if USB works but I suspect the network code. As soon as I have some time I will test over Wlan. I suspect a timing issue. In the recent rewrite when I added scan button and IPv6 support I may have broken something. My device is normally ethernet connected. My time is right now limited (too much work at $DAYJOB), so it may take a week before I will be able to do so.
