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 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.
Hii can someone help me please. My wifi is not connecting on my LG webos TV LJ5500 smart tv. I cannot even screen share either. Neither with miracast or wifi direct. .any suggestions pls
Cable was working fine. Had to unplug TV and cable to reboot because the TV screen kept cutting to black and was up to about 30 seconds each time (it gets progressively longer, until I unplug the TV and cable box, and do the hold-the-on-button-for-10-seconds-and-start-over fix, which has worked in the past for this problem, as well as the app restarting for memory thing). Well, now I’m unable to get the cable signal back.
— I swapped cable box from HDMI 1 to 2 and Apple TV from 2 to 1. No signal from cable in HDMI 2, but Apple TV worked in 1.
— Bought new HDMI cord. No signal.
— Restarted the TV from scratch and re-setup everything No signal.
— Called cable company and had them troubleshoot. No signal.
— Hooked cable box to another TV. Bam! Signal! Works fine!
So, why won’t the TV recognize the cable box? I have Consolidated Communications, but cable’s worked when accidentally set to AT&T, as well as Comcast in the past.
Sorry if I sound dramatic, but I’m really, really irritated that I spent $1900 on a TV that has to be rebooted multiple times a week, and the fact that I’ve seen posts on here regarding the app reset problem dating back to 2017, yet LG’s chosen not to fix this issue. It’s ridiculous.
