I tried it. See this post on the RioReceiver BBS. It doesn't seem to work. Only one dvice would get an IP if using DHCP. If using static IPs, only one IP is pingable and/or usable. I also tried using a hub instead of switch. Still no luck.

The way I have it set up now is I have my wireless router in my stereo rack. Of course, all 3 wired ports on that thing work properly. My PC is using a Orinoco USB gold adapter and i sync the empeg through the router.
