WiFi issues, drops continuously and sometimes switchs off

Richard Bowden


Recently moved my 49SJ810V to another room where I can no longer cable to the router. It takes nearly 10mins for the WiFi search to find anything. Then sometimes fails to connect with correct login details. Then when it does it drops continuously and never stays for more than a few mins at at time. It even switches of the WiFi altogether!! Everything in my house connects fine and I've even got an even older LG up stairs that needs a WiFi dongle and I've just tried that and it works fine. Looks to me like its the software that is the issue. It has the latest  version installed.  I've done all that's recommended on the LG website. Any ideas?

I had a similar issue started occur recently with Wi-Fi dropping out, streaming media buffering (I'm on FTTP so shouldn't have been) then after a few days it started switching Wi-Fi off altogether and wouldn't turn back on at all.

I powered off at the plug for 5 minutes, Wi-Fi was fine for 2-3 minutes then dropped and switched off, when switching back on it just wasn't seeing my access point at all.

I factory reset, Wi-Fi was okay, reinstalled apps, halfway through logging into them all, Wi-Fi dropped again. Can't reconnect to it.

I started looking at new TV's from Richer Sounds, and was on the verge of purchasing a slightly larger model when I thought I'd have a look at replacing the network card.

Then...I found a YouTube video that instructed the following:

  1. Go to Settings
  2. General
  3. Location
  4. LG Services Location
  5. Select another country (it will warn you about losing access to certain services, accept this and TV will reboot)
  6. Go back to the same menu
  7. DISABLE the setting at the top, either called 'Automatically Detect' or 'Set Automatically'
  8. Reselect your correct Country in the list
  9. TV will reboot again
  10. RESULT! Do not re-enable that Detect Automatically setting - this seems to be a very weird bug where that setting is causing the network card to drop out.

Since doing this - no more buffering, no more Wi-Fi dropping or disabling itself, and everything is perfect.

Hope this helps you as it did me!

      Quelqu'un pour m' aider?

      i thought of using my handphone to act as a remote control for the TV.............but it will only work with WiFi ??!!

      i had BlueTooth still turned on..............TV is using LAN connection only.........and the phone can no longer control the TV (the phone can control the TV with WiFi on)............is this normal ?? 

      many thanks in advance............

      My LG SJ850V stopped finding any wifi network about a week ago. The software version is 6.10.30. I don't know the reason this could happen, as it was working perfectly fine a week ago.

      55UJ651V After a few minutes, the Bluetooth clicks and disconnects. Sometimes it then re-starts the tv into the on mode, with nothing selected. It will not find the bluetooth device again. Unless, I try a different Blutooth device and then it does the same thing all over again. Is there any answer to this - or does the module need replacing. There seems to be a lot of discussion online regarding Bluetooth issues with LG. I have hearing issues and must use headphones! This is impossible!

      I recently bought an LG UK6500PLA TV (my first LG), but I have a difficult time streaming content (Wifi connected), e.g. Netflix series is streaming in low resolution.  The router is only 10 feet away from TV (but ethernet is not an option) and uses a 5GH frequency range.
      I have tried making a speed test at fast.com, for both the TV (through the Webbrowser) and for my laptop and iPhone. The speed test for TV showed 2.5 Mbps and my laptop and iPhone showed 110 Mbps. Can there really be such a big difference? I am starting to wonder if this might be a warranty issue?
      Do any of you guys have experience with bad Wifi reception on your LG TV or have any suggestions on how to fix it?
