WLAN doesn’t have a very high WAF (Women Aceptance Factor). Thus it’s wired. Server is Debian with 2.6.12-ct-1 kernel and DNS, DHCP, Twonky, and Firefly 1082 (upgraded manually to 1084). Problem exists as I wrote since the beginning of my “Firefly-career”.
I hope Roku and Ron are going to tackle this soon or give me a hint how to analyze on my own.
