Well, I spent about 5-6hrs trying to get my SB working last night. The unit is in my lounge about 15ft away from my router which is in my study. It appears from some posts on the slimdevices forums my wireless network is simply not up to the rate FLAC requires. It cannot transmit 1000kbps reliably enough. 500kbps yes, but not 1000kbps. And this is with the unit in a compromised position in the louge, ie: not where I'd ideally like it, but somewhere where I can put up with it - This position is about 5-6ft closer to the router and increases the signal strength from about 30 odd % upto about 60-70 odd %. So, I think if I wish to use the unit I'll have to use 320K MP3 instead of FLAC. I'm not overly concerned about this as from what I've read (& thus far tested) it's very hard to hear any difference, even when actively comparing the two, yet alone just listening to it 'none-the-wiser'. Also it means I use about a third of the disc space as well Just wondering what other SB owners have encountered with their wireless config etc?
