Popup messages: Wired Lan cable disconnected / Wired network is connected

Recommended Posts

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.

We purchased and LG UHD SmartTV with WebOS at end of July 2018.  The following messages continuously alternate re. the Wired Ethernet connection whenever the LAN cable is plugged in, i.e.  "Wired network is connected"  followed immediately by  "Wired Lan cable disconnected".

However, the router is stable and there is a trouble-free, continous Wi-fi connnection to the same Smart TV.  There are also no failures for other devices connected via a Wired Ethernet connection to the same router.

Dear LG ... is this a WebOS software issue or is it a SmartTV network card issue ?  If this is not resolved very quickly we will dump this TV and buy SAMSUNG instead.

Dear John,

 

I suspect that you are enjoying the use of a wireless connection.  Whereas, if you disconnect from the wireless connection (ensure you have the password on hand for re-connection) you may see that you have no internet connection (via Wired Ethernet) whatsoever.  If in addition, you unplug the LAN cable (at the SmartTV socket's end) you will note that the repeat message re. Wired Ethernet disappears.

There is an outside chance that your Wired Ethernet connection distribution point (opposite to the end of the LAN cable connected to your Smart TV) may be faulty.  To check this, connect some other device e.g. a laptop computer (perhaps even using a replacement Ethernet Cable) and observe whether that device can establish a trouble-free internet connection, or not as the case may be.  If you find a trouble free internet connection this way, the problem is narrowed to the LG Smart TV, and it may be either a software or hardware issue, or both of these.

I have the same problem. It is very annoying.

I have wireless disconnected and only ethernet connected. 

Already switched cable to other ports in the router, switched physical cable,  and the problem remains.

I wonder if this is a hardware fault (ethernet board on tv) or is this a webos (software) problem?

LG, please resolve this as it seems that more people have the same issue.

You only benefiting from a wireless connection. 

Can you elaborate on that?

How do i benefit from reducing comunications from 1Gb/s to 100Gb/s? Not to mention traffic collision wich wifi suffers from.

I called LG customer service and they wanted  me to do a total reset on the tv.   I was  afraid it would wipe out my calibration that was done by a professional calibrator , so I didn’t try it.   

 

There has had to be some solution.

Great TV, but it’s ridiculous to have to put up with it.

This has to be a software issue, I have had the main board replaced all my cables checked and multiple Router devices tested. Same issue. 
hopefully in next firmware update they can resolve this.

Similar problem with the annoying pop up messages for my 43 UJ6200 .

Messages most often that an unknown device is disconnected,  followed immedietly with unknown device is connected and it's repeated many times,  then stops for a short or long time, and then happens again with varying frequency.

Occasionally,  I get the pop up that my Lan connection is disconnected followed by Lan connection is connected.

By the way,   I only connect via an ethernet cable to my router so wifi isn't even set up for my tv.    The only other device connected is my cable box via an HDMI cable.

All connections have been checked and tv has been power cycled in a specific way as per LG support advice and tv dusted in back also per support instructions,   but problem persists and is very annoying at times.

Someone mentioned problem persists after changing out motherboard,  so his assumption was that it's software related.

Would be great is someone from LG could read this and pass it along to find a fix for it .

Mine was worse with the initial  motherboard Now it’s Better it’s very random now could be days And even weeks. I also think there is definitely an app triggering this from the LG content store or LG settings. The fact that multiple models and people reporting the same error is definitely  software /firmware.  Would like someone in LG R&D to acknowledge this issue and supply a fix?

I haven't as I didn't want to go through all my custom picture and other settings,   but I thought I've seen that somebody did that.    Could be mistaken about that.

If I knew it would fix the problem,   I'd try it and just renew all my settings.

Has anyone done a hard reset on the tv to see if it helped any?

Yes, I did it before my replaced Brand new motherboard, it slowed down the messages which were happening every 15-30 min. After new motherboard install it happens maybe once every couple of days.
