LG TV Won’t Connect To Wi-Fi: How I FIXED It

Navigating the maze of Wi-Fi connectivity issues on an LG Smart TV can be a real headache. I know this firsthand from my experience with my LG CX OLED. While I ultimately opted for an Ethernet connection for its stability, the journey led me through a series of troubleshooting steps that I’ve found to be incredibly useful.

So, even if you’re like me and decide that a wired connection is the way to go, this guide will walk you through the ins and outs of diagnosing and fixing Wi-Fi issues on your LG Smart TV. From basic checks to advanced settings, we’ve got you covered.

1 – The Basics: Initial Checks

Check Network Connection

Before you dive into more complex solutions, it’s crucial to confirm that your LG Smart TV is attempting to connect to the correct Wi-Fi network. To do this, grab your remote control and navigate to Settings > Connection > Network. Here, you’ll find a list of available networks. Make sure your TV is connected to your personal network, not a guest network or a neighbor’s.

Password Errors

Believe it or not, something as simple as a password error can be the culprit behind connectivity issues. When entering your Wi-Fi password, remember that it’s case-sensitive. Double-check to ensure that you haven’t accidentally toggled the caps lock or made a typo. A single incorrect character can make all the difference.

These initial checks may seem basic, but they’re the building blocks for more advanced troubleshooting. Skipping these could lead you down a rabbit hole of unnecessary steps, so it’s worth taking a moment to confirm these basics.

2 – Intermediate Steps: Power Cycle and Interference

Power Cycling Devices

Sometimes, the age-old advice of “turning it off and on again” holds true. If you’ve confirmed that you’re on the correct network and your password is accurate, the next step is to power cycle your devices. Unplug your modem, router, and TV from the electrical outlet and wait for at least 30 seconds. Plug the devices back in, starting with the modem and router. Wait for the link lights to stabilize, and then plug in your TV. This simple act can often refresh your network and resolve connectivity issues.

Potential Interferences

In today’s connected world, your home is likely filled with devices that could interfere with your TV’s Wi-Fi signal. Other routers on the same channel, outdated firmware, or specific router settings can all be contributing factors. Take a moment to consider what other electronics are in the vicinity and whether they might be causing interference. If you suspect this might be the case, you may need to delve into your router settings or update your firmware.

3 – Network Isolation: Identifying the Culprit

Connecting to a Different Wi-Fi Network

If you’ve exhausted the basic and intermediate troubleshooting steps without success, the next logical step is to isolate whether the issue is with your TV or your network. One effective way to do this is by connecting your LG Smart TV to a different Wi-Fi network. In my case, I used the personal hotspot feature on my iPhone, which was connected to a cellular network. This serves as a clean test environment, separate from your home network.

If your TV successfully connects to another network—like it did with my iPhone’s hotspot—it’s a strong indicator that the issue lies with your home network and not the TV itself.

4 – Software Updates: Keeping Your TV Up-to-Date

Checking for Updates

Staying current with software updates is more than just getting new features; it’s about ensuring the optimal performance of your device. To check for available updates on your LG Smart TV, navigate to Settings > General > About This TV > Check for Updates. If an update is available, you’ll have the option to download and install it. It’s a good practice to keep your TV’s software updated, as manufacturers often release patches that can resolve a variety of issues, including those related to Wi-Fi connectivity.

5 – Advanced Troubleshooting: Beyond the Basics

Some features on your LG Smart TV, like Simple Link, can occasionally interfere with your Wi-Fi connectivity. To disable this feature, navigate to Settings > All Settings > General > SimpleLink. Toggle the feature off and attempt to reconnect to your Wi-Fi network. It’s surprising how such a seemingly minor setting can sometimes be the root cause of more significant issues.

6 – Expert-Level Fixes: DNS Settings

Changing DNS Settings

If you’ve reached this point and are still facing connectivity issues, changing your DNS settings could be the solution. To do this, navigate to Settings > Network > General > Wi-Fi > Other Network > Advanced Settings. Here, you’ll find the DNS server settings. Uncheck the box that says “Set Automatically” so you can enter a DNS server manually. In the text box, change the DNS server to, which is a public DNS server often used for troubleshooting. After setting the new DNS, reboot your TV by unplugging it for 30 seconds and then plugging it back in.

Update Router Firmware

Another expert-level fix to consider is updating the firmware on your Wi-Fi router. Manufacturers regularly release firmware updates that can improve performance and fix known issues, including connectivity problems. To update your router’s firmware, you’ll need to log in to your router’s admin panel through a web browser. The exact steps can vary by manufacturer, so consult your router’s manual or support website for detailed instructions.


It’s worth noting that Wi-Fi connectivity issues aren’t exclusive to LG Smart TVs; they’re a common challenge for many smart tv brands. However, the steps outlined in this guide can serve as a blueprint for diagnosing and resolving these issues, regardless of the brand or model you own.

While Wi-Fi offers convenience, it’s hard to beat the stability of a wired Ethernet connection. That’s precisely why, after navigating through my own Wi-Fi challenges with my LG CX OLED, I opted for an Ethernet connection. It’s a decision that has provided unparalleled stability, allowing for a seamless entertainment experience free from the frustrations of intermittent connectivity.
