Hello,
I had the same issue, basically lan disconnect/connect messages accompanied by inability to turn Wi-Fi on and network cuts during those pop-up. After reading all the posts in the forum and someone mentioning he removed Netflix and Amazon prime, I decided to try the following:
1. Removed all necessary icons from start menu (royku, lg channels, filmin, etc,) only left YouTube Netflix and Amazon Prime and Disney+.)
2. I disabled LG channels
Amazingly the messages have now stopped completely and WiFi networks now appear so I am now connected to both Ethernet and WiFi!
Good luck to you all and I hope it works for you. It is definitely a software issue since what really seems to have helped in my case was removing shortcuts from the start/home menu, I didn't even have to uninstall anything... Weird
Will let you know it thenfix is permanent, but I have a good feeling after being able to scan wireless networks, this wasn't working for ages.
