I have a streamer connecting through Wifi (802.11n, WPA2-AES) to my NAS box. When I look at the Bandwith->Last 24 Hours I see its traffic under the WL(eth1) tab. The numbers seems to make sense, compared to the media's bitrate. Strangely(?), when I look at the IP Traffic->Last 24 Hours streamer's IP tab I see no traffic at all.
