For those who get frequent WiFi connection drop-outs, I picked this bit of useful info from another forum. Note that this may well apply to many other LG models than the C9, as they often use common WiFi internal cards/modules:
Problem: C9 [or other models] will lose the wireless connection and you have to reconnect daily (but wired is stable);
Conditions: TV is connected to a 5GHz router;
Cause: (1) the router may be unstable on the 5GHz band [possibly too far from router]; (2) the router has the 5GHz band set on a higher channel - over 100;
Resolution: (1) change the TV to the 2.4GHz band
(2) set the channel [in the ROUTER advanced WiFi settings]!! for the 5GHz band below 100 (ex. 40-50) - [channel 36 is often OK]."

I have lg tv model 49UJ6525, last weekend the tv updated to version 05.80.35, but now I realized that I can no longer use the 5 GHz WIFI network, the network is disconnecting and connecting all the time. I did a test with the 2.4 Ghz network and it works normal, but I would like to use the 5GHz network.
Is it possible to solve this problem?

I recently updated the firmware on my LG43UH610V. Now I constantly get "Wired Lan cable disconnected" / "Wired network is connected" messages even while watching a video file from my NAS. The TV is connected and using the network while getting these messages. It has always been on a fixed IP address on the LAN.
After updating my TV (OLED65GXPUA) on August 31, 2020 the HDMI-ARC volume support changed: pressing the volume up/down button once on the magic remote will continuously apply volume changes until the volume has reached the maximum or minimum value. Prior to this update volume changes over the HDMI-ARC interface behaved as expected: one press of the remote button would apply one increment or decrement to the volume. A Klipsch Bar 48 is attached to the TV over the HDMI-ARC interface.
After the update the TV is running: webOS TV version 5.1.1-3701, Software version 03.10.41. I do not have the version information prior to the update.
