I keep getting disconnected from SL, every couple hours, and I keep getting this message when I try to log back in. The interesting thing is, even when I lag out and get disconnected, SLVoice.exe remains connected. I'm lagged out, but still talking until the system realizes I'm disconnected, and switches off voice. My instant messengers and my PING monitors all stay connected, as does my XBox 360 on the same network. I'm not running wireless.
Anyone have any theories? I keep wanting to blame the SL servers, since it's not my connection, but no one else on the sim with me has trouble with it, so I doubt it's that either. If it's not on my end and not on their end, could it be a system thing? Just for giggles, here's my system info out of Help > About Second Life...
