Hi There, Our computer (Windows 8 Home) is getting cabled into our network at home soon, but until then we have it on a Belkin 300Mbps USB wifi connection (getting about 250 real world).
For some reason PMS (latest version) does not want to work over the wifi network: When i run a long ethernet cable across the floor from the computer to our switch, the LG TV sees the DLNA network and sees PMS - and works as expected. If i disconnect the wired network and enable the wifi network adaptor, make sure its connected and re-start PMS, the LG TV says there is no DLNA device available... I have tried choosing the "Belkin Wifi Adaptor" from the "Force networking on interface..." as well.
PS: We also have AirVideo server running for our iOS devices, and that works over both ethernet and wifi.
