Tried now for 3 days and still can't get soundbar to connect to wifi. Done everything I Can find in help files including cables out TV and the st300. Factory reset modem restarts the lot. Also had 2 solid amber lights on it and only way to get them off was take plug out, remote would not shut it down. I have now got the LG TV working with hdmi arc, also my bluray and xbox one. Managed to get the app to work by trailing an rj45 cable across the lounge which is not acceptable with a £600 soundbar.
