Changing your home network password is a standard security procedure faced by every smart home device owner. When you update the access keys in your router, your TV loses its internet connection because it attempts to use old, invalid credentials. This necessitates Change the Wi-Fi password on your TVto resume access to online cinemas and Smart services.
Updating network settings on your TV screen can seem confusing due to differences in interfaces between manufacturers. However, the steps are similar for most models. You'll need a remote control and access to your router's current settings. We'll walk you through all the details so you can quickly restore your connection.
It's important to understand that the TV can't automatically "guess" a new password. The device will endlessly try to connect with the old data until you forcefully delete the old network profile or make changes to the configuration. Sometimes it's easier to forget the network than to try to edit its settings.
Why won't my TV connect after changing my router password?
The main reason for the lack of connection is the device's cached data. The TV stores it in memory. Network SSID and the associated encryption key. When you change the password on the provider's side or in your router's personal account, the TV continues to send an authorization request with an outdated key. The router, receiving invalid data, blocks the connection.
Many users mistakenly believe that simply entering a new password in the error window is sufficient. However, Android TV, Tizen, or webOS systems often don't immediately provide this option. They may display an "Incorrect Password" message with no input field. In this case, you need to completely delete the network profile from the list of saved ones.
It's also worth considering the encryption type. If you accidentally changed the security standard when changing your password (for example, from WPA2-PSK on WPA3), older TV models may not physically support the new protocol. In this situation, changing the password won't help until you return to a compatible encryption type in your router settings.
⚠️ Note: If your TV only supports the 2.4 GHz band, and your router only broadcasts on the 5 GHz band after changing the password (or vice versa), connection will also be impossible. Make sure the frequency bands are active.
Sometimes the problem isn't with the password, but with IP addressing. A sudden change in security settings can cause the router to reset DHCP clients. The TV may become stuck with an old IP address that's no longer valid for the current session. Restarting both devices often resolves this address conflict.
Preparation: What you need to know before setting up
Before using the remote, make sure you have the current Wi-Fi password handy. It's best to write it down on paper or keep it open on your smartphone screen to avoid entering it incorrectly. Even a single character or letter case error will result in repeated access denials.
You may also need to access the router interface if you plan to change the network name (SSID) in addition to entering the password. Separating networks into "Guest" and "Main" is a great way to secure your Smart TV from unauthorized connections. To access the admin panel, you'll usually need the gateway address, for example, 192.168.0.1 or 192.168.1.1.
Check your TV's software version. Outdated firmware may contain bugs that prevent it from reconnecting to Wi-Fi correctly. If possible, update the system via an Ethernet cable or USB drive before attempting to set up a wireless connection.
- 📝 Write down the new Wi-Fi password in large letters.
- 📱 Make sure you have a smartphone with mobile internet access handy to search for instructions.
- 🔌 Check that the Wi-Fi module is enabled on the TV itself (not in Airplane mode).
- 📡 Find out the exact name of your network (SSID), especially if your neighbors have networks with similar names.
A universal algorithm for changing the password on a TV
Regardless of brand, the basic setup logic remains the same. You need to access the network connections menu. Typically, the process goes like this: go to the main menu, select "Settings," then look for the "Network" or "Connection" subsection. This displays the current connection status.
The key is to find the option to manage saved networks. It may be called "Network List," "Wi-Fi Direct," "IP Settings," or simply display your network's name with a gear icon next to it. Select your network and click "Forget," "Delete," or "Disable." Only then will the TV allow you to enter new information.
Menu -> Settings -> Network -> Wi-Fi -> Select Network -> Forget/Remove -> Scan -> Select Network -> Enter PasswordAfter deleting the profile, tap "Scan for Networks" or "Refresh." When the list reappears, select your network. A keyboard will appear on the screen for input. Be careful: it's difficult to tell whether Caps Lock is on or which language is selected on the remote. Use the navigation buttons to switch between numbers, Latin, and Cyrillic characters.
☑️ Checklist before entering your password
After entering the password, the TV will begin the authentication process. This can take anywhere from 5 to 30 seconds. If the status changes to "Connected," check your internet browser or YouTube app. If the "Limited" or "No internet access" icon is displayed, the issue may not be with the password, but with the date and time settings.
Instructions for popular brands: Samsung, LG, Sony
Smart TV interfaces vary, so we'll look at specific steps for leading manufacturers. These steps will help you quickly navigate the menus.
For TVs Samsung (Tizen OS): Press the Home button on the remote. Go to Settings (the gear icon on the left). Select General -> Network. Click Open Network Preferences. Select Wireless. Find your network in the list, click it, and select Delete or Forget. Then select it again and enter a new password.
To the owners LG (webOS): Press the gear button ("Settings") on the remote. Go to "All settings" (three dots). Select "Network" -> "Wi-Fi connection." Tap the name of your network. In the menu that appears, select "Delete profile" or "Forget network." Then, reselect the network from the list and enter the details.
For Sony and other brands on Android TV: Press the "Quick Settings" button (gear icon) or go to your profile. Select "Settings" -> "Network & Internet." Tap the gear icon next to your Wi-Fi network name. Select "Delete network." Go back, turn Wi-Fi on if it's off, find the network, and enter a new key.
| Brand | Path to the network | Action | Peculiarity |
|---|---|---|---|
| Samsung | Settings -> General -> Network | Remove device | Confirmation required with the Return key |
| LG | All Settings -> Network | Forget the network | Convenient quick access via the settings button |
| Sony (Android) | Settings -> Network & Internet | Delete network | The interface is similar to a smartphone |
| Xiaomi | Settings -> Network -> Wi-Fi | Forget | Manual IP entry is often required. |
⚠️ Note: On some Samsung and LG models, deleting a network may require entering a parental control PIN if one was previously set. If you don't remember it, you may need to perform a full reset of the TV.
Alternative methods: WPS and cable connection
If entering a password from the remote control causes difficulties (the cursor jumps, the characters are not visible), you can use the technology WPS (Wi-Fi Protected Setup). This method allows you to connect your TV to your router without entering a key, simply by pressing the button on the router. However, this method only works if you know the current password or it's still valid, or if WPS doesn't currently require a password for pairing.
To activate WPS, go to your TV's network settings and select the WPS connection method (push-button or PIN code). If you select "Push-button," press the physical WPS button on the router (the indicator light will usually blink). The TV will automatically receive the access data. Keep in mind that many modern routers have WPS disabled by default for security reasons.
The most reliable way to troubleshoot a network error is to connect via cable. LANIf your TV has an Ethernet port, connect it to the router with a cable. A wired connection often takes priority over a wireless one. Connecting via cable will allow you to check for system updates, which may improve the wireless module's functionality. After updating the software, try setting up Wi-Fi again.
- 🔘 Find the WPS button on your router (often combined with the Wi-Fi power button).
- ⏱ Press it and immediately start the WPS search on the TV (2-minute timer).
- 🔌 A LAN cable eliminates password entry errors and provides maximum speed.
- 🔄 After connecting via cable, be sure to check for software updates.
Using a cable is especially important if the TV's wireless module malfunctions after changing the router settings. A wired connection completely resets the network stack, which often helps to "shake up" the system software.
Troubleshooting: If your password is not accepted
There are situations where you enter the password perfectly, but the TV displays "Connection Error" or "Incorrect Password." First, check the encryption type. TVs older than 5-7 years may not support the standard. WPA3Go to your router settings (via a PC or phone) and temporarily set the router to compatibility mode. WPA/WPA2 Mixed.
The second common cause is an overflowing device list in the router. If you have many devices connected, the router may not assign an IP address to the TV. Try rebooting the router by unplugging it for 30 seconds. This will clear the ARP table and DHCP leases.
It's also worth checking MAC filtering. If MAC address filtering is enabled on your router, even the correct password won't help. You need to find the TV's MAC address (in the "About TV" or "Network Status" sections) and add it to the whitelist of allowed devices in the router settings.
⚠️ Note: Router interfaces (Keenetic, TP-Link, ASUS, MikroTik) are constantly being updated. The menu item layout may differ from that described. If you cannot find the encryption type setting, please refer to the documentation for your router model.
As a last resort, if nothing helps, you can perform a full reset of the TV to factory settings (Factory Reset). This will delete all your accounts and apps, but is guaranteed to clear any network errors. After turning on the TV, it will go through the initial setup, where you can enter a new password from scratch.
Frequently Asked Questions (FAQ)
Is it possible to change the Wi-Fi password directly from the TV remote?
No, the TV is a client device. It can only use The connection password is set, but the network password itself cannot be changed. To change the password, you must access the router settings from a computer or smartphone.
What should I do if the character entry button on the remote control doesn't work?
Try connecting a regular USB computer mouse to the TV. This will allow you to quickly click using the on-screen keyboard. You can also use the remote app on your smartphone if the TV and phone are on the same network (or if the phone is connected via mobile data and the TV via Wi-Fi Direct).
Will the Wi-Fi password be reset if I unplug the TV?
No, Wi-Fi settings are stored in non-volatile memory. After a power outage, the TV will attempt to connect automatically using the saved (old) password. To change these settings, you must manually enter the menu.
Why does the TV see the 5 GHz network but not connect?
Your TV may not support the 802.11ac/ax standard, or there are restrictions in your region. Try separating the 2.4 GHz and 5 GHz networks into different SSIDs in your router settings and connecting to the 2.4 GHz network, which has better penetration.
