In this guide, I will walk you through a series of effective steps to resolve the ‘Wi-Fi Password Incorrect’ error on Smart TVs, a common issue across brands like Samsung, LG, and Sony. 

Drawing from my personal experience with these fixes, I assure you that these solutions are not only tested but also practical and easy to implement.

Let’s begin.

Quick Solutions That Could Work

Wait Patiently: Sometimes, a Smart TV just needs a moment to establish a connection. I’ve noticed that when I turn on my TV and immediately try to use an app like YouTube, I might encounter a connection issue. 

From my experience, patiently waiting a couple of minutes, or sometimes just a few seconds often resolves this. It seems the TV simply needs a bit of time to connect to Wi-Fi after being powered on.

Reset Your Router: The issue may stem from your Wi-Fi network. Try turning off your router, waiting for about 30 seconds, and then turning the router back on. This can help resolve temporary network glitches that might be causing the Wi-Fi password error.

Soft Reset Your TV: To reset your TV’s internal processes without altering your settings, turn off your Smart TV, unplug it from the power source for a minute, and then plug the cables back in. This can refresh the system and potentially fix connection issues.

Factory Reset Your TV: If the problem persists, a factory reset might be essential. This will return your TV to its original settings and can resolve deeper software issues. Be aware that this will erase all your personalized settings and installed apps.

Forget and Reconnect to the Network: Navigate to your TV’s Wi-Fi settings, forget the network, and then reconnect. When re-entering the Wi-Fi password, ensure accuracy. This process can often resolve incorrect password errors.

Check Router Settings: Verify your router settings, especially features like MAC filtering, to ensure your Smart TV is allowed on the network.

Consider TV’s Proximity to Router: Make sure your TV is within a reasonable range of your router. Too much distance or physical obstacles can weaken the Wi-Fi signal, affecting connectivity.

The Tricky Keyboard Design

Entering a Wi-Fi password on a Samsung TV using the remote control can test anyone’s patience. 

I’ve personally navigated this challenge, pressing a key and getting a green check mark or the delete icon instead of the intended letter. It’s like being in a tech maze, isn’t it?

To ease this, I found a trick: when the check mark appears, I click the directional button twice to bypass it. But the ultimate solution for me was using a physical keyboard. 

Connecting a keyboard to my Samsung TV transformed the way I input passwords – it turned a stressful task into a breeze.

Manually Setup Internet Via IP Settings 

Manually configuring your Samsung TV’s internet connection using your Wi-Fi router’s IP information is a solid solution when standard methods don’t do the trick. 

This method has been successfully used by a member of the Samsung community. 

Here’s how to do it:

Step 1: Perform a soft reset on your Samsung TV. Unplug all the cables from the TV and leave it unplugged for 2 to 3 minutes.

Step 2: In the meantime, grab your smartphone and connect it to the Wi-Fi network you plan to use. Access the Wi-Fi settings on your phone, select the information icon next to the connected network, and note down the IPV4 Address and DNS information.

Once you have got all of the information, disconnect your phone from the Wi-Fi by turning off the Wi-Fi on your phone.

Step 3: Turn your TV back on and navigate to the Internet configuration menu. Then attempt to connect and enter the Wi-Fi password. 

If the TV does not connect, it will prompt you to change to a different network or to adjust the IP Settings. 

In that case, select ‘IP Settings‘ and manually enter the IP and DNS information you noted from your smartphone.

Following the above steps should enable your Samsung TV to connect to your Wi-Fi network seamlessly.

LG

Uncheck the Automatically Services Country

Adjusting the Services Country settings manually has been a successful fix for internet connectivity issues on many LG TVs. 

Here’s what you need to do:

Step 1: Navigate to All Settings → General → System → Location → LG Services Country.

Here, uncheck the Set Automatically option and select a different country.

Step 2: After changing the location, your LG TV will automatically restart. Once the TV has restarted, attempt to reconnect to your Wi-Fi network.

Disable the Automatically Time

Another potential fix for Wi-Fi connectivity problems on LG TVs involves disabling the Automatic Time setting:

Here’s how to do it:

Navigate to All Settings → General → System → Time & Date → and then uncheck Set Automatically.

These simple yet effective adjustments in your LG TV’s settings can sometimes be all it takes to solve Wi-Fi connectivity problems, ensuring a smooth and uninterrupted viewing experience.

Sony 

Your Sony TV Can’t Connect to 5GHz Bandwidth

A number of Sony TV users have experienced issues with connecting to the 5GHz Wi-Fi band, which is known for faster speeds but can sometimes be unstable or glitchy.

One effective solution, as shared by a user on Reddit and verified through my own testing on a Sony KD-43X75K TV, involves tweaking the Channel Control settings for the 5GHz bandwidth.

Alternative Connection

Use Ethernet Instead

If the Wi-Fi ‘wrong password’ issue persists despite trying the previous solutions, consider switching to an Ethernet connection.

Ethernet offers a more stable and faster internet connection than Wi-Fi, which can significantly enhance your TV’s online performance. 

Simply connect an Ethernet cable from your router to your TV to enjoy a more reliable and consistent internet experience.

Add a Streaming Device

This might sound unconventional, but it’s a solution that many users have adopted. 

When their Samsung TV experiences persistent Wi-Fi glitches and they prefer not to engage in extensive troubleshooting, they opt for a streaming device. 

By connecting devices like an Apple TV box or a Fire Stick to their Samsung TV, they bypass the built-in Wi-Fi issues.
