Modern smart TVs Samsung Smart TV TVs have become an integral part of the multimedia space in every home, providing access to streaming services and online cinemas. However, like any complex digital device, they can experience software failures, especially when it comes to network connections. It's quite common for a TV to stop detecting the router, fail to connect to the internet, or attempt to use incorrect settings.
In most cases, a standard disconnection or reconnection does not help, as the device continues to use cached data old configuration. This is where it becomes necessary to perform a procedure that in technical terminology is called "forget the network." This action causes Tizen OS completely delete the connection profile and clear all security keys associated with it.
In this article, we'll cover in detail all known methods for deleting network profiles on various Samsung TV models. We'll cover both standard methods via the settings menu and more in-depth reset methods that can help in more complex cases. You'll learn how to correctly diagnose the problem and apply the most effective solution for your specific model.
Why is it necessary to delete a network profile?
At first glance, it might seem like it's enough to simply enter a new password if the old one stops working. However, the TV's operating system Tizen The TV is designed to prioritize saved configurations. If you've changed your router but left the same network name (SSID), the TV may try to connect using the old ones. encryption protocols or a static IP address, which results in an endless connection loop.
Additionally, a common cause of crashes is an overflowing list of saved networks. Samsung TVs have a limited buffer for storing WiFi profiles, and if it fills up, new connections may not initiate correctly. Deleting unnecessary or problematic networks frees up system resources and eliminates addressing conflicts.
There's also the issue of incorrect session termination. If the router was rebooted while actively transmitting data, the TV could retain the broken connection. In this case, the "forget network" command acts as a forced disconnect, resetting the network module to its initial state.
⚠️ Note: Deleting a network will erase all saved passwords. Make sure you have the current access key for your WiFi router before clearing the list.
It's important to understand the difference between a simple disconnect and a full wipe. A disconnect only terminates the current connection, leaving the settings in memory. A full wipe requires re-authorization, which is often the only way to force the device to go through the process again. handshakes (handshake) with an access point.
Preparing to set up the network
Before making any changes to system settings, ensure your equipment is ready. Performing the wrong steps may prevent the issue from being resolved the first time. First, check that the internet is working on other devices connected to the same network.
It's recommended to have a remote control with working batteries ready in advance, as menu navigation requires precision. Also, have your WiFi network password handy, as the TV will require you to re-enter it after deleting your profile.
☑️ Preparing for a network reset
If you plan to change router settings (such as channel frequency or encryption type), it's best to do so before tinkering with the TV. This will prevent a situation where you delete a network and the router is still not ready for a new connection.
Standard method via the settings menu
The safest and manufacturer-recommended way to remove a network is to use the standard interface. Smart HubThe interface may differ slightly depending on the model year and firmware version, but the logic remains the same. To get started, press the button Home on the remote control to bring up the main menu.
Next, you need to go to the settings section. On newer models, this is a gear icon; on older models, it's a button. MenuIn the window that opens, find the section General or NetThis is where all internet connection parameters are concentrated.
Select an item Network settings or Open network settingsA list of available wireless connections and their current status will open. Find the network your TV is connected to or that's saved in memory.
- 📡 Click on your network name to open the context menu.
- 🗑️ Select an option "Delete" or Forget the Network (Forget Network).
- ✅ Confirm the action if the system asks for confirmation.
- 🔄 After deleting, the network will disappear from the list of active ones, and you can connect again.
In some interface versions, the delete option is hidden in an additional menu that is called up by the button Tools or the three-dot button on the remote. If you don't see the delete button right away, look closely at the bottom of the screen or the side panels.
⚠️ Note: The Samsung TV interface is updated periodically. If the options described here don't match your screen, look for similar names, such as "Network Management" or "Wi-Fi List."
Using the Network Reset feature
If deleting a specific network doesn't help, or if the network list is behaving erratically, you can use the full network settings reset feature. This option returns all internet-related settings to factory defaults without affecting personal files or installed apps.
To perform this operation, go to Settings → General → Net. Find the item at the bottom of the screen or in the submenu Network resetThe system will warn you that all network settings will be deleted.
After confirmation, the TV will reboot the network module. This action is equivalent to the command "forget all networks" at once. This is especially useful if you've changed providers or purchased a new router with different security features.
| Parameter | Before the reset | After reset |
|---|---|---|
| Saved WiFi networks | All previously connected | The list is empty |
| DNS settings | Custom or auto | Automatic (default) |
| MAC address | No changes | No changes |
| Installed applications | Saved | Saved |
It's important to note that after resetting your network, you'll need to re-login to all internet-required apps if they can't do so automatically. However, this ensures that no old conflicts will interfere with your experience.
Troubleshooting through the engineering menu
In cases where standard methods fail due to firmware errors (bugs), more advanced methods can be used. The engineering menu allows access to hidden diagnostic functions. Be careful: changing incorrect parameters here may impair the TV's operation.
To access the service menu on the remote, press a sequence of buttons. On remotes without numbers (Smart Remotes), this is often done through the menu: Settings → Support → Device Information, where you need to quickly press a button several times Return or a combination of buttons (depending on the model, often Mute + 1 + 8 + 2 + Power on old remotes).
The dangers of the engineering menu
Changing settings in the Advanced or Calibration sections may result in incorrect color or sound display, or even the complete inoperability of smart features. Only access these settings if you understand what you're doing.
Inside the menu, find the section related to Network Control or WiFi ModuleThere may be an option there. Factory Reset WiFi or Clear Network ConfigUsing this function forces the wireless module's memory to be cleared.
If you're unsure of what you're doing, it's best to limit yourself to a reset using the standard menu or a full reset of the TV. The engineering menu is intended for specialists and may not be localized in Russian, increasing the risk of error.
Complete reset of TV settings
When none of the above methods helped to forget the WiFi network on Samsung Smart TV, there remains a radical but effective solution: a full factory reset. This will return the device to its "as-is" state, erasing all user data, accounts, and settings.
This is done through the path Settings → Support → Self-diagnosis → ResetThe system will ask for a PIN code, by default it is 0000After confirmation, the cleaning process will begin, which will take a few minutes.
This method is guaranteed to remove all network profiles, as it erases all user-defined system configuration. This often resolves not only WiFi issues but also other software glitches that have accumulated over time.
- 📺 All Samsung and streaming service accounts are deleted.
- 📡 The list of all ever connected WiFi networks is cleared.
- 🔄 Image and sound settings are reset.
- 📁 Apps may require reinstallation or re-authorization.
⚠️ Caution: A hard reset is a last resort. Make sure you have internet access via your mobile phone (for tethering) so that the TV can update the time and service agreements immediately after the reset.
Diagnostics and common mistakes
Even after successfully deleting a network, users may still encounter difficulties reconnecting. Often, the problem lies not with the TV, but with the router settings. Make sure your router isn't using MAC address filtering, which could block the device after the reset.
Another common mistake is choosing the wrong frequency. Older TV models (pre-2019) may not support the standard. WiFi 5 GHzIf your router only broadcasts a 5 GHz network, your old TV simply won't see it, no matter how much you try to "forget" it and reconnect it.
It's also worth checking the date and time on your TV. If the time settings are reset, the security certificates may be invalid, causing a connection error even with the correct password.
In rare cases, outdated firmware is the culprit. If the network module is not working properly, try updating the TV's firmware via a USB drive, downloading the latest version from the manufacturer's official website.
Frequently Asked Questions (FAQ)
