Changing an internet provider or router often confronts owners of smart devices with a fact: their favorite Smart TV The device stops connecting to the network. This is normal, as the device is simply trying to connect to an old access point that is no longer in the air. To regain access to online movie theaters and apps, you must manually update the wireless connection settings in the TV menu.
Process Wi-Fi changes On Samsung TVs, reconfiguring doesn't require any special technical knowledge, but it does require careful password entry. The Tizen operating system interface, which underlies modern models, is logical and structured, but the layout of options may vary slightly depending on the device's year of manufacture. In this article, we'll cover all the steps of reconfiguring in detail, as well as methods for resolving common connection errors.
Before you begin tinkering with the settings, make sure your new router is turned on and broadcasting a signal. If you've just installed new hardware, wait until it finishes booting up. Only then can you begin using your router's remote control. Samsung.
Equipment preparation and compatibility testing
The first step is to physically check the network's functionality on other devices. Take your smartphone or tablet and make sure they see the new network and can connect to it. This will rule out issues with your ISP or a faulty router. If the internet works on your phone but the TV doesn't, the problem lies with the TV settings or frequency band.
Modern routers often operate in two ranges: 2.4 GHz and 5 GHz. Older Samsung TV models may not support the 5 GHz frequency, so when searching for networks, they will simply ignore the new router's name if it's hidden or only broadcasts at a higher frequency. In this case, you need to go to the router settings and ensure the 2.4 GHz network is active.
⚠️ Note: If your router uses the "Smart Connect" function (combining the 2.4 and 5 GHz network names into one), try temporarily separating them into different names (SSIDs) in the router settings so that the TV can correctly identify the appropriate range.
It's also worth checking the distance between the router and the TV. Walls, especially load-bearing ones, and household appliances can cause interference. For the initial setup, it's recommended to move the router closer to the TV or use a Wi-Fi extender if the signal is too weak. After successfully connecting and entering the password, the device can be returned to its original location.
Network switching algorithm in the Tizen interface
Most modern Samsung TVs run the Tizen OS. The interface is standardized, but the path to settings can vary. Most often, users need to press a button. Home on the remote control (house icon) to open the main menu and go to the leftmost column.
In the menu that opens, select the item Settings (gear icon). The next step is as follows:
- 📡 Select a section General or Net depending on the firmware version.
- 🔌 Go to the subsection
Netand select Open network settings. - 📶 From the list of available connections, select Wireless (Wi-Fi).
- 🔍 Find the name of your new network in the list and click on it.
- 🔑 Enter your password using the on-screen keyboard and confirm the action.
After entering the password, the TV will attempt to establish a connection. If the password is correct and the signal is sufficient, a successful connection message will appear on the screen. The system may prompt you to update the software or accept the Samsung Services user agreement—it's recommended to complete these steps for stable operation. Smart Hub.

Setting up Wi-Fi on Android TV models
Some Samsung TV models, especially those released for specific markets or older series, may be based on the Android TV platform. The operating logic here differs from Tizen, as the menu structure follows Google standards. Settings are typically accessed using the gear button or the [unclear] button. Settings on the remote control.
In the main menu of the Android TV system, you need to find the section Network and Internet. All available interfaces are displayed here. Select the item Wi-Fi and turn the switch to the "On" position if it's off. The system will begin scanning the airwaves.
⚠️ Note: Android TV sometimes encounters an error where the network list is empty, even though the router is working. In this case, try a full reboot of the TV (unplug it from the power outlet for 1 minute); this will reset the network module.
Once the list appears, find the desired SSID. Clicking on it will open a credentials entry window. A special feature of Android TV is the ability to use your smartphone to enter text through the app. Google Home or Android TV Remote Control, which significantly speeds up the process, since entering characters with the remote control is long and inconvenient.
Troubleshooting: TV doesn't see the new network
A common situation is when your router's name isn't listed among available networks. This can be caused by several factors, from a hidden SSID to incompatible encryption standards. First, check to see if the network name is hidden in your router settings (Hide SSID option). If it is, you'll need to add it manually using the "Add Network" option in your TV menu.
Another common cause is that the list of saved networks is full. The TV's Wi-Fi module can store a limited number of profiles. If you frequently change routers or connect to guest networks, the memory may be full. In this case, resetting the network settings can help.
It's also worth paying attention to the channel your router is running on. Some bands (especially 12 and 13 in the US) may not be supported by TVs intended for other markets. Try hard-coding the router's 2.4 GHz channel to 1, 6, or 11 in its settings.
Why is TV region important?
Regional restrictions (CIS, EUR, USA) affect available Wi-Fi channels and signal strength. If your TV is imported from another country, it may not be able to see certain channels used by your router.
Reset network settings and complete restart
If simple methods don't help change your Wi-Fi settings, you should reset your network settings. This will delete all saved passwords and IP address configurations, returning your network module to its "as is" state. It's important to understand that this won't affect your personal files or installed apps, only your connection settings.
To perform a reset on Tizen, go to Settings → General → Network → Network ResetThe system will warn you that all settings will be deleted. Confirm the action and wait for the module to reboot. After this, repeat the process of searching for and connecting to the new network again.
| Type of problem | Probable cause | Solution method |
|---|---|---|
| Doesn't see the network | Hidden SSID or incompatible channel | Add manually or change the router channel |
| Connection error | Incorrect password or encryption type | Check your password and change encryption to WPA2. |
| Constant breaks | Weak signal or interference | Use a repeater or change the location of the router |
| Limited connection | Problems with DHCP or DNS | Set a static IP or DNS 8.8.8.8 |
In rare cases, a full reset of the TV to factory settings helps (Settings → Support → Self-diagnosis → Reset). Use this method only if other methods have been exhausted, as you will have to set up all applications and accounts again.
Using a wired connection and alternatives
If your TV's Wi-Fi module is unstable or doesn't support modern speed standards, a wired connection via Ethernet cable (LAN) is a reasonable alternative. This will ensure maximum stability and speed, which is critical for viewing 4K content. Simply connect the router and TV with a cable, and the setup will happen automatically.
For models where the LAN port is missing or inconveniently located, USB Wi-Fi adapters can be used. However Samsung Officially supports only proprietary adapters (WIS12ABGNX series and similar), which are no longer in production. Third-party adapters will not work.
Another option is to share your smartphone's internet connection via a USB modem. Many modern Android phones allow you to connect to a TV via a USB cable and share your internet connection. This is a temporary solution, but it can be helpful in an emergency.
Frequently Asked Questions (FAQ)
Is it possible to change the Wi-Fi if the remote doesn't work?
It's difficult, but possible, to navigate the TV menu without a remote. If you have a smartphone with an IR port, use a universal remote.
