    Hello lbertran,

    Let's try hard reset.
    Make sure the tv is ON, Do a hard reset.
    1. Turn it off, and unplug it from the power outlet.
    2. While the unit is turned off, look for the power button on the unit itself, press and hold it for about 15 seconds. 
    3. Unplug all devices connected at the back of the unit. Let the TV rest for about 1 minute, then turn on again

    Thank you.

    My TV just started doing this last month.  WiFi no longer works but Ethernet works but I can’t stream anymore as it constantly disconnects.  I am at wits end.  I put it in store mode and disabled pop us and then put it back in home mode.  Pop ups still occur.  I refuse to leave it in store mode because that’s means I can’t disable soap opera effect.  What are my options?  Is my tv board broken since WiFi is broken and Ethernet streaming is no longer working?  This may be my last ever Lg device.

    LG India support said my wifi card is bad and the problem but since I’m outside one year by a month I’m out of luck and will need to pay for a repair.  That’s the last LG product I ever buy.  I Can’t believe you have to be in store mode to disable pop ups.  What a piece of junk.

    Hi everyone,

    I'm gathering data to escalate this issue. Can everyone post your model and firmware version and any notes you think may help isolate the cause. Thanks!

    I have posted in several spots and will post here also since the moderator asked for info. My model is 55UJ6300 and the firmware was the latest one. I have reset it. The WiFi says turned off. I have done everything suggested. The tv was a year old in October. It was fine until the latest update and then it couldn’t find my WiFi then we turned everything off (router) and tv and still no luck. Unplugged tv and then it showed up as WiFi was off. Turned off quick start ,didn’t help. Did reset didn’t help.

    My TV has the same problem, at the beginning there was only a message that it had disconnected from the network and it had reconnected, this happened once a week and it was only those two messages, in November the messages from an unknown device were I began to appear sporadically, in December the messages come out every 10 minutes, my wifi is disconnected and I can not activate it, I connect by cable this gives me access to the internet but in minutes I lose it again which makes me use Netflix, Amazon Video and YouTube are practically impossible. In addition to this the remote control stops working, the cursor does not appear on the screen and the response of the buttons has a lag that makes it impossible to use it and a couple of weeks ago the TV restarts after the messages go out without stopping for several seconds. I would believe that this is a hardware problem as this affects the wireless communication of the remote control, so I think it is a problem with the wireless card, my TV is still under warranty but I want to know if it is a problem of software also since I see that several indicate that the problem was presented after the firmware update.

    TV: 55SJ8000
    Software Version:  05.80.15

    In adision of my previous comment, I have connected to the TV cablebox, PS4 and Xbox. I have done everything that indicates to do a hard reset, disconnect all connected devices, disable the SIMPLINK. I have used the TV without any connected device including the network cable, antenna, optical, etc etc and it still gives me the same message and problems.

    I have the LG 65UJ6300 which my wife bought on Thanksgiving 2017, so this TV is 13 1/2 months old. Has a 1 yr warranty (which I feel is ridiculous for an $800 TV). I too am experiencing the pop up message about unknown device has been disconnected (annoying). BUT, I have a more serious problem recently too. The screen sometimes goes blank when I change the channel, but still have audio. Also, sometimes, it seems it does a quick "reset" without doing anything while watching it. Another problem, seems WiFi isn't good enough or not working at all, but my computers and cell phones etc never experience a problem. What give LG? Willing to help a disabled senior citizen out here? My 10 yr old 55" Panasonic still performs like it did new.

    The way I got rid of the annoying message was to go into store mode,go to settings, general and scroll down to the bottom once in store mode you click on the menu on the left and you can turn off the store settings ,the screen will be brighter though. Techs are supposed to be working on an update.
    If you can hook up to Ethernet cable you can have internet. I am not close to my router so I used a Fire stick and that works.

    I know store mode hides those messages...but the TV looks like garbage in that setting. My 7700 just started doing this a couple days ago starting with the unknown device, then lan disconnected now it randomly reboots as well. I have a teach coming Saturday from LG, hopefully they have a fix.  Most recent firmware does this as well as one the one previous to this.

    Mods, any update on a potential fix?  In addition to the wifi and "unknown device" issues, i have image freeze and stutter now on netflix, youtube and broadcast tv, and netflix buffers more or less all the time, although Amazon Prime video is still good, and the tv is generally slower and less responsive across the board.  It is pretty clear that the last firmware update was a disaster.

    If nothing else, can we have a way to rollback to a prior known to be good FW?
