UPDATE: So after reading some of the recommendations about the issue of "Network Disconnected" on LG TV's, and FREEZING, sound stopping on LG TV's, I decided to follow some of them. And, thusfare, I have solved my problem. What I did:
I laid the TV on my bed, face down. I removed all the visible screws on the back panel and removed it. I found that there are some "ribbon cables" (They're called that because they resemble ribbon material) that have tight bends, and are taped together going from the system board down to the lower center of the TV where the power button and the WIFI card is. I carefully removed the tape holding them tightly together, and carefully straightened the cables out (as best as possible, you won't be able to really straighten them) where they had tight bends. I then tightened the screws that hold the system boards (two boards) to its frame, they were pretty loose. I also gently pushed on the connection points of the ribbon cables to assure tight connection. (NOTE: On my TV, the lower portion where the wifi network card and power button is located has a plastic frame of sorts that I too losened to be able to get to those cables properly). I then put everything back together, and, I am happy to say, NO MORE PROBLEM. So, in my case (and more than likely in yours too) it appears to be a cabling issue where overtime the laws of gravity mess things up (and/or transportation of the unit) losening things up like the connections and/or screws). So, I'm a happy customer on my own account. I hope this is helpful. PROBLEM SOLVED. (On another note, turning off notifications or disabling features or other items via the settings on the TV is not a fix, I don't recommend doing so).
Hello, I am writing to you from Italy, I had the same problems described here, slow remote control, apps like youtube lag or block for no reason, the continuous pop up of the messag “ethernet cable inserted / disconnected”, in short, a total mess. thanks to this procedure I solved the problem on my LG 55UJ750V. Maybe I also understood why LG has never given us an answer, I have worked for years in the assembly of electronic equipment and what I have seen in the boards and connections looks like the work of an unskilled worker ... some flat cables badly connected and a fixing screw was missing… in short LG could not help as they could not admit their low quality assembly…
