Did something change that broke this or have I misconfigured something? After some fiddling with pimd, route, miniupnpd, minissdpd, etc, I have ended up where the client on wireless (Xbox360 console) can see my wired computer (Win 8) but when it tries to open it, it can't browse the contents. This works when both are on the same wireless, but I get some buffering/lag in video playback</div>

I was then able to hint Dave where the issue might be and it really was working out of the box for me (Wired Samsung TV, win7 laptop on 802.11g and n).<br>Unfortunately since then I was never able to figure out what's going on.

When I put the computer on the same wireless as the console, then open the Network folder and hit refresh, the Xbox pops up along with other things on wireless (Roku, etc) but when the computer is wired, it doesn't see any of those, so I think something about the SSDP packets isn't working quite right between subnets or with pimd. My guess is the SSDP search from the computer isn't getting to the wifi, only vice versa.</div>
