I have a Samsung UN46F6300. Just changed internet & cable provider to Knology/WOW. (Was with Comcast & TV connected wirelessly.) Now I can see the access point/router/modem. However when I put in security password and try to "connect to internet", it does not connect. last night, I moved the tv into room where router/modem is located and I hooked it up via a wired connection & connected and downloaded Firmware updates (as Samsung chat suggested). Initially it connected wirelessly. However, once I moved tv back to original location, it lost internet connection again. Any suggestions. I purchased the Samsung LAN adapter WIS12ABGNX but it is not recognized when I plug straight into USB port.
