Sorry for the long delay in my response. My Actiontec GT704-WG gave up on moving any traffic at all through the 10/100 ports. With new home network gear, Actiontec DSL Modem + Linksys WRT54G, I started over and had no troubles at all. I ran for three full days without losing contact. I rebooted the Roku Soundbridge it found the Firefly right away. 🙂
I was so happy I launched into (and just finished) “un-slinging” a Linksys NSLU2 and have made it my “always on” Firefly media server.
