I jusr bought the samsung uh46eh5300 I can connect using the cat5 connection that is another story. anyway after spending my entire afternoon getting the Internet working with a samsung tech. I couldn't connect wireless. I would go through the network settings and start connection wireless and the screen goes back to the tv screen. I then complete a factory reset and it finds my network name I entered the code and it tries to connect with a wired connection instead of wireless connection and I don't have a wire connection to the tv it is unplugged. Samsung rep says I needed a wireless lan adapter wis12abgnx. I didn't understand why I needed this I thought the tv had a built in wifi. I think maybe the wifi module is bad. Any help would be greatly appreciated thx.
