Modern Smart TV Samsung's smart TVs are complex multimedia centers that require a stable and reliable internet connection to function properly. Without internet access, updating the Tizen operating system, running streaming services like YouTube or Netflix, or using Smart Hub features is impossible. However, users often need to change network settings, for example, after purchasing a new router, switching providers, or updating their home network security key.
Changing the Wi-Fi password on a Samsung Smart TV can be confusing due to the interface differences between different firmware versions. Unlike smartphones, there's no immediate pop-up window when a new network is detected, and manual access to the configuration menu is often required. It is important to understand, that incorrect actions may lead to loss of connection with other smart devices in the home or reset of important user settings.
In this article, we'll detail the steps for different models of different years, explore methods for forced network searches, and troubleshoot common authorization errors. You'll learn how to correctly enter a new security key, whether to use WPS, and what to do if your TV stops detecting your router after changing the password. Critically
Preparing to change network settings
Before you begin entering new data, you need to make sure your equipment is ready. If you just changed the password on your router, make sure it's written correctly, without typos, and case-sensitive. Users often forget that Wi-Fi is case sensitive and confuses uppercase and lowercase letters, resulting in endless connection attempts.
It's also worth checking that the wireless module in your TV is enabled. Some Samsung models have a power-saving feature that can turn off the network adapter if the device has been in standby mode for a long time. Make sure the remote control is working properly and has sufficient batteries, as menu navigation requires precision.
Samsung TV interfaces may vary depending on the model year and operating system version. On older models with the Orsay platform or earlier versions of Tizen, the menu may look different than on modern QLED and Neo QLED series. Therefore, it's important to rely on the logical structure of the menu, not just the icons.
⚠️ Note: If your router broadcasts networks in two bands (2.4 GHz and 5 GHz) under the same name, the TV may attempt to connect to the less stable band when changing the password. We recommend temporarily separating the network names (SSIDs) in your router settings for more accurate diagnostics.
Step-by-step instructions for Samsung TVs (Tizen OS)
The basic procedure for most modern models released after 2015 is based on the Tizen operating system. To change the Wi-Fi password on a Samsung Smart TV, you need to access the main settings menu. To do this, press the button. Home on the remote (often indicated by a house or colored circle) to bring up the smart menu and select the item Settings (gear icon).
In the menu that opens, find the section General or go directly to the item Net, if it is in the main menu. In some interface versions, you need to select Open network settingsHere you'll see a list of available wireless networks. If your router has already been paired with your TV, it may show "Connected" or a lock icon next to its name.
☑️ Password change algorithm
Click on your network name. The system will prompt you to enter a password. If the field is already filled with asterisks, you'll need to clear it. Use the virtual keyboard that appears on the screen, carefully entering the characters. Once entered, click Ready or OK and wait for the connection check. The TV will attempt to obtain an IP address from the router.
If authorization is successful, a connection message will appear on the screen, along with details about the signal strength and IP address. If an error occurs, double-check the characters you entered. Sometimes, deleting the old network from the list of saved profiles before trying again helps.
Using the WPS function for quick connection
For those who do not want to manually enter long and complex combinations of characters, there is a technology WPS (Wi-Fi Protected Setup). It allows you to connect devices with a simple press of a button. Your router should have a physical button labeled accordingly, and your Samsung TV's menu should support this protocol.
To use this method, go to the menu Net -> Network settingsSelect the connection type WirelessWhen the list of networks appears, find the button at the bottom of the screen WPSPress it and the TV will go into signal standby mode.
Within 2 minutes, press the WPS button on your router. If your router doesn't have a physical button, you may need to press it in the router's web admin interface. The TV will automatically receive the necessary connection details, including the new password if it has been changed.
Why might WPS not work?
The WPS function is considered less secure than manually entering a password, as it is vulnerable to brute-force attacks. Some modern routers and TV firmware may have this function disabled by default or completely removed for security reasons.
This method is especially convenient if the remote control is faulty and navigating the virtual keyboard is difficult. However, it's important to remember that WPS only works in the 2.4 GHz band and may not work if the router is configured to operate exclusively in 5 GHz mode with a hidden SSID.
Reset network settings to factory defaults
Sometimes, network cache errors or conflicting connection profiles can prevent the TV from working correctly with a new password. In such cases, the most effective solution is a complete network reset. This will return the network settings to their original state, as if the TV had just left the store.
To perform a reset, go to Settings -> General -> Net. Find the item Network reset or Expert Settings (Expert settings), where the reset button is located. The system will warn you that all saved Wi-Fi passwords will be deleted, and you will need to re-authorize all network services.
After confirming the action, the TV may reboot. Once the process is complete, you'll need to reselect your network from the list and enter the current password. This method often resolves issues where the TV "sees" the network but can't obtain an IP address or displays a DNS error.
| Parameter | Before the reset | After reset | The need for action |
|---|---|---|---|
| Saved networks | All previously connected | The list is empty | Re-entry required |
| IP address | Static or dynamic | Dynamic only (DHCP) | Manual setup if needed |
| DNS server | Automatic or manual | Auto | Checking provider settings |
| Samsung Services | Authorized | Requires login | Entering your account password |
⚠️ Note: Resetting your network will not affect installed apps or user data (photos, videos), but some apps may require re-authorization within themselves, as they will lose internet access during the reset.
Solving common connection problems
Even with the correct password, users may encounter a number of difficulties. One of the most common issues is that the TV doesn't detect the 5 GHz network. This is because many older Samsung models or budget models only support the 2.4 GHz band. If your router is broadcasting a 5 GHz network with the same name, try separating them into different SSIDs in the router settings.
Another common error is related to the security type. Samsung TVs require the router to have an encryption standard installed. WPA2-PSK (AES)If you're using legacy WEP or mixed WPA/WPA2 mode, your device may refuse to connect or continually request a password. Issues may also arise when using Cyrillic characters in the network name or password—it's best to use only Latin characters and numbers.
If your TV displays "Unable to connect to server," the problem may not be with the password, but with the date and time settings. Check that the time and date are set correctly in the menu. System -> TimeIncorrect time invalidates security certificates, and the router blocks the connection.
In rare cases, an overflowing DNS cache can cause problems. Try entering public DNS server addresses, such as Google's, in your TV's network settings (under IP settings, in Input mode).8.8.8.8) or Cloudflare (1.1.1.1). This often speeds up interface response and stabilizes streaming.
Setting up a static IP address for stability
For advanced users seeking maximum connection stability, setting up a static IP address is recommended. This is especially important if your home network has many devices and the router frequently changes addresses, which can lead to disconnections with media servers or smart home systems.
In the network settings menu, select IP settings and switch the mode with Receive automatically on Manual entryYou will need to enter the IP address (must be in the same subnet as the router, for example, if the router is 192.168.0.1, then the TV can be given 192.168.0.50), subnet mask (usually 255.255.255.0), gateway (router address) and DNS server.
Using a static address also helps if, after changing the password, the router assigns a new address to the TV, but in a smart home system (e.g., Home Assistant or Mi Home), the device is bound to the old IP address. In this case, fixing the address solves the control issue.
When entering parameters manually, be extremely careful. A single digit error in the gateway or subnet mask will prevent the connection. If you're unsure of the values, it's best to leave the settings to automatic, as modern routers manage address pools quite efficiently.
FAQ: Frequently Asked Questions
Is it possible to connect a Samsung TV to Wi-Fi without a remote?
Entering a password manually using only the buttons on the TV is nearly impossible, as navigating the virtual keyboard requires the directional pad. However, if you've previously installed the Samsung SmartThings app on your smartphone and linked it to the TV, you can use your phone as a remote to enter the password.
Why does the TV say "Incorrect password" even though I'm entering it correctly?
This could be due to several reasons: Caps Lock is enabled, the wrong keyboard layout is selected (symbolic instead of alphabetic), or the router is using MAC address filtering. You can also try temporarily disabling router security (making the network open), connecting, and then resetting the password—this will help you figure out the error.
How do I find my TV's MAC address to configure my router?
The MAC address can be found in the menu Support -> Device Information or in Settings -> Net -> Network statusIt looks like a combination of letters and numbers separated by a colon (e.g., 00:1A:2B:3C:4D:5E). This address may be needed to set up parental controls or a whitelist on the router.
Will changing the Wi-Fi password reset app settings (Netflix, YouTube)?
No, changing network settings or even a complete network reset will not affect the data inside installed apps. Your logins, passwords, and browsing history will remain intact. However, you will need to reconnect to the internet for the apps to work.
