Is there any way I can confirm the gadget is actually working and

IPTraf and filter on the gadgets IP address, needs to be run on a

Wireshark on a machine connected into an ethernet tap somewhere
between the WiFi AP and the router to the ineternet. Might be tricky
if the AP is part of the the router.
