This is a persistent problem experienced by many -including myself, virtually ALWAYS starting virtually after the warranty ends. I bitched to LG for several months and threatened a class action lawsuit as this is a pernicious issue in three levels: (1) the hard-wired internet goes on and off maddenly, primarily in the evenings, (2) the wifi connection menu becomes UNAVAILABLE further making internet totally unavailable and (3) in our case the sound synchronization being lost even through a single movie. ASK FOR SUPERVISORY REPONSE....you will have put put up with the BS attempts by "technicians" to fix the problem. They won't call back as promised to check in with you. Soooo, then call again and struggle through the crappy connection and the almost unintelligible response, hang in there and insist on talking with a supervisor. Then, if you are lucky or a totally miserable nag, you may get forwarded to "EXECUTIVE SERVICE" with a CLEAR CONNECTION to a HUMAN AMERICAN whom you should be able to convince (I hinted around about a class action lawsuit because this is an ACROSS-THE-BOARD WELL KNOWN ISSUE). Just today, we got an offer of paid repair for our issue for which the local service company called us just today, after I girded my loins for a final call on this BS. Hope this helps.
