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.
