Fix: LG TV WiFi is Turned Off or Keeps Disconnecting

If you are having problems connecting your LG TV to the internet, it may be due to some issue with the hardware. For example, if your TV does not detect any WiFi connections and says “WiFi is turned off turn on to connect WiFi, it means that there’s some problem with the WiFi module installed on your TV.

If WiFi is turned off on your LG TV you should talk to an LG support representative to get the WiFi module replaced. However, before you opt for the WiFi module replacement, you must try a workaround.

In case your LG TV keeps disconnecting from WiFi or WiFi is turned off, it also may be due to a small issue with the WiFi module. In most cases, it’s the WiFi module cable that connects the WiFi board to the WiFi antenna which causes such connectivity problems on LG Smart TVs.

Loosening the WiFi cable might fix the LG TV network connection problems such as frequent WiFi drops and failure to detect wireless networks.

Make sure to check 3 things after you have removed the back panel of your LG Smart TV.

  • Flatten the WiFi ribbon or cable if it’s crimped.
  • Clean the connectors on both ends of the WiFi cable.
  • Loosen the 5 pieces of cable in the WiFi ribbon.

Let’s see how to do this.

  1. Get a screwdriver that fits appropriately in the screws used in your TV.
  2. If your LG TV is on a stand let it be that way. Unmount your LG TV from the wall or detach the TV stand and place it on a flat surface covered with a soft cloth with the screen of the TV downwards.
  3. Take out all the screws used on the panel edges of your TV.
  4. You won’t be able to remove that back panel of your LG TV yet as you need to take out 3 more screws as shown below.lg smart tv pack panel screws
  5. Remove the back panel of your LG TV.
  6. You’ll now be able to see the WiFi module.

  7. As you can see above, there is a blue tape that combines the 5 pieces of the WiFi cable.
  8. Remove this blue tape using a blade and separate the 5 cables from each other very carefully. Alternatively, separating the two main wire bundles to prevent crimping will also do the job.
  9. Also, Unplug the cable from its socket, clean any dust stuck to it, and plug it back in.
  10. One more thing, if you see that the WiFi cable ribbon is crimped, do flatten it and stick it to the base to keep it that way. Use an extra piece of tape if you need to.lg tv crimped wifi cable straighten wifi cable riboon
  11. Put the back panel of the TV back and tighten the screw.

Now connect your LG TV to a wireless network to check if it still keeps disconnecting from WiFi. This should really fix the WiFi connection drop issue.

  1. Press the Settings button on your TV remote, navigate to All Settings, and click on it.
  2. Open the General settings and click on Additional Settings.lg smart tv general settings

Troubleshooting LG TV Network Connection Problems

If you tried the fixes described above and your LG TV still keeps disconnecting from WiFi or you’re encountering network connection problems, try the following tips.

Restart the Modem or Router

Blaming the TV for network connection problems is very easy. However, before you do that you should check your WiFi router settings and the connection itself. Turn off your WiFi router for 1-2 minutes and then turn it on. Check if your TV connects to WiFi or not. Sometimes you may have a network connectivity issue due to some problem from the network provider’s side. Call your ISP (Internet Service Provider) to ensure there’s no problem with the internet connection. Try connecting your other devices to test the connection, if you’re able to access the internet on other devices, try the next tip.

To verify if the problem is with your TV or the WiFi router, try connecting your TV to your smartphone by enabling the Hotspot feature.

Shorten the WiFi Network Name

Typically, you can set any name for your WiFi network (0-32 characters). However, if the security type of your WiFi network is WPA2-Personal, I would recommend keeping the WiFi network name short (up to 8 characters). Try connecting to WiFi after you have changed the name.

Change WLAN Network Band

If your internet service provider offers a 5GHz network and you have got an LG Smart TV released prior to 2019, you may have network connection problems because the TV won’t be able to detect the network and connect to it. In that case, it’s a good idea to change the network band from 5GHz to 2.4GHz.

Open the WiFi router settings page in a web browser and go to Network. Look for Band and change it to 2.4GHz.

Now, reboot your WiFi router and see if your TV can connect to the WiFi network or not. If you don’t know how to do this on your own, contact your ISP and ask them to change the network band to 2.4GHz and the channel to 6 or 11.

Place the WiFi Router near the TV

The large flat surface of the TV and the antenna’s location (which typically faces the wall) might cause radio frequency signal interference. It may result in a weak signal or a WiFi connection drop intermittently. To eliminate the radio frequency signal interference, it is recommended to keep your WiFi router near the TV and insure that there’re no obstructions. Alternatively, you can also try a WiFi Repeater to strengthen the WiFi signal. It may help you enjoy a seamless connection if your LG TV keeps disconnecting from WiFi.

Connect LG TV to the Internet via Ethernet Cable

If there’s some problem with the WiFi module of your TV and it can’t connect to a WiFi network wirelessly, Connecting your TV to the internet with the ethernet cable is a better idea than going for a WiFi module replacement on your LG TV.

Unblock Your TV’s MAC Address

In case the MAC address of your TV is blacklisted by your internet service provider, you should get it unblocked.

  1. Go to All Settings > General > About This TV and look for the MAC Address (Wireless).
  2. Note it down, contact your ISP, and request them to add it to the whitelist.

You can do it yourself by opening the WiFi router settings page in a web browser and going to the router’s firewall settings.

Reset Your LG TV

In case your LG TV can not establish a connection to a WiFi network and you have tried all the tips mentioned above, It may be due to some glitch on your TV. To solve the issue you should reset your TV to factory settings as directed below

  1. Press the Settings button on your LG TV remote and navigate to All Settings > General.
  2. Highlight the Reset to Initial Settings and click on it.
  3. Confirm the reset and go through the initial setup on your TV.

Try connecting to your wireless network by going to the Connection settings.

Update LG TV Firmware to the Latest Version

If none of the tips and tricks to fix the LG TV WiFi connection problems worked for you and your TV still keeps disconnecting from WiFi, consider updating your TV’s firmware to the latest version. If you don’t know how to do that, head over to my guide describing the method to update LG TV firmware via USB.

Use Amazon Fire TV or Roku Stick or Box

Well, using an Amazon Fire TV stick or Roku stick or box is not a solution to fix WiFi connection problems but it might at least let you enjoy smart TV features unless the connectivity issues of your TV are fixed.

  1. Dear sir/madam,
    Bigthanks to you! I highly appreciate your advice. I flattened the ribbon inside of my LG tv as per your instruction and now it is connected again on the wifi.. more power and thank you

  2. I’ve been dealing with constant no wifi connections and dropping the connection for as long as I’ve had my LG OLED 55″ C8 model. As a retired IT/Computer tech, I thought I did everything to resolve this issue, but with no success! I was resigning myself to replacing the wifi module in the TV, which would have been a lot of work! I use my laptop and iPhone in the same room as the TV and those items have no issue with connecting to WiFi! I finally decided to change the 5gHz channel on my router, which is an Orbi with one satellite. The Orbi 5gHz channel had always been set at 48 and I had no issues with any other WiFi device using 5gHz. I set the channel to the lowest one, which is 36 and, guess what? My TV now connects within seconds of turning on! Every time! Not a single article or website I’ve found, and there have been dozens, ever mention about something as simple as changing WiFi channels, but rather performing all types of useless steps that, as a tech, I know have nothing to do with my TV not connecting! I hope this information will help others with this incredibly frustrating issue with their LG Smart TV not connecting, or constantly dropping, the WiFi connection! As and FYI, if your TV only supports the 2.4Ghz band, try changing the channel for that band. The channels to try are 1, 6 or 11.

    1. Thanks for sharing this, Robert! It will surely help others fix the WiFi connection problem on their LG TV. Different solutions work for different TV models.

  3. I have a 49uj752t and had constant wifi issues. The tv will not work on 5ghz and would just freeze up. I created a 2.4ghz SSID for the tv and that resolved the freezing but the tv would still drop out while watching Foxtel/plex/etc. After uncrimping both the curled up section and the section near the Wifi the tv is now working with 0 dropouts.

    Rakesh. You are a legend! No need to just throw away a 4 year old TV.

    Anyone else. Don’t be afraid to give this a go.

  4. Same thing here! Both my 2 LG TVs also keeps constantly disconnecting from wifi now. It’s only started recently and none of my other devices in the house have the issue. I’ve tried all the steps recommended above 100 times and am SIC of it.
    When are you going to fix this, LG?
