OK I don't get it... I don't get power cables either but I'm wrong again. I've been using WIFI to my fanless PC streamer and have had a plugin access point for years with an ethernet port so to hook it up I just had to dig up a long enough ethernet cable and try it.... and dang it sounds better than WIFI. It's WIFI to the extender WTF??? The only thing I can figure is the ethernet port is on a different bus than the WIFI port and it lowers the noise floor.
Thanks GH!
