Only two months ago I connected the TV with an Ethernet cable to our central wireless router, as this has better quality than a wireless dongle connection. So far so good, all works fine.
However, a couple of weeks ago I wanted to connect the wireless media box, but it failed to connect to the TV. The media box is a kind of concentrator for the TV, so you can connect all kind of video (+audio) sources to the box, like a video player, karaoke set, satellite set-top box, etc. The box connects wirelessly to the TV, so you can even have your equipment in another place in the room and still play all on your TV, by selecting the source on the front panel of the box.
Here begins my story. Let me tell you that I am NOT unsatisfied with my purchase and also not with the final solution, but I am amazed how the LG service organisation(s) in this area is organized, or may be they are not, and about the money they are probably wasting!
