Changing your home wireless network password often becomes necessary when the router has been reset to factory settings or the ISP has changed the access keys to enhance security. At this point smart TVA device that previously connected automatically to the internet stops connecting and requires new data. The user needs to know how to properly delete the old network from the device's memory and enter the latest information.
The procedure is not always intuitive, as the operating system interfaces WebOS, Tizen or Android TV may differ from each other. Entering characters incorrectly or selecting the wrong encryption type often results in the device displaying "incorrect password," even if you enter it correctly. Understanding how network modules work will help you avoid common connection issues.
In this article, we'll detail the steps for TVs of various brands, explain why authorization errors occur, and provide solutions for complex cases. Important: After changing the password on the router, all devices must be reconnected again, as the old saved keys no longer work. Be prepared to pay close attention to the capitalization of letters as you type.
Preparing to change network settings on your TV
Before you begin setup, make sure you have the latest connection information. You'll need the exact name of your wireless network (SSID) and the new password. If you're changing your router settings, it's best to write this information down on paper or save it in a note on your smartphone to avoid having to search for it while entering it.
It's also worth checking whether the router itself is working and sending a signal. Go to a TV with the router turned on. Wi-Fi moduleMake sure your remote control is working properly, as menu navigation often requires precise cursor positioning. In some cases, it's more convenient to use a smartphone remote app if it's already paired with the TV.
⚠️ Important: If you changed the password on your router but haven't updated it on your TV, the device will continually try to connect with incorrect information. This could block network access for other devices if the router detects a suspicious number of connection attempts.
It's recommended to disconnect unnecessary devices from the router during setup to reduce bandwidth usage and avoid IP address conflicts. This is especially important for networks with a limited address range. After completing these preparatory steps, you can proceed directly to the settings menu.
Removing the old network and clearing memory
The most important step is deleting the old network profile. TVs often cache connection data, and simply attempting to "refresh" the network list may not work. You need to forcefully delete the saved configuration. To do this, go to the main menu and find the section Settings → Network.
Find your network in the list of available and previously used networks. There's usually a checkmark or lock icon next to the network your device is or has been connected to. Click on your network's name to open the context menu.
- 🗑️ Select the "Forget network" or "Delete profile" option to completely erase old keys.
- 🔄 If you don't see this option, try selecting "Reset" or "Change".
- 🚫 In some models Samsung And LG You need to press the "D" or "Tools" button on the remote control to open the hidden menu.
Once deleted, the network will disappear from the "favorites" or "connected" list. Now, when scanning the airwaves, the TV will perceive your access point as a new, unfamiliar network, forcing the system to request the password again. This solves 90% of connection error loops.
Instructions for Samsung TVs (Tizen OS)
Interface Tizen OS The setup is simple, but the settings path may vary depending on the model year. Most modern models follow the same algorithm. Press the "Home" button on the remote, then navigate to the gear icon in the upper left corner.

Pay special attention to the keyboard layout on the screen. WebOS The Russian keyboard layout is often enabled by default, even though passwords require Latin characters. Switch the language by tapping the corresponding button on the on-screen keyboard.
- 🔤 Switch the input language to English if the password contains Latin letters.
- 👁️ Use the "Show Password" feature to visually check whether you've entered complex characters correctly.
- ✅ Click "Connect" and wait for the message about successful authorization.
If your LG TV isn't detecting your network, try disabling the "Quick Start+" option in the network settings and rebooting the device. This resets the network stack and often helps find hidden networks.
What should I do if the keyboard doesn't appear on the screen?
If the virtual keyboard doesn't appear, try pressing the "Return" or "Back" button on the remote while in the input field. In some cases, connecting a USB keyboard or mouse to the TV port helps.
Changing your password on Android TV and Google TV
TVs based on Android TV (Sony, Philips, Xiaomi, Haier) have a similar menu structure, as they all use the same Google platform. Go to the upper right corner of the screen and select the gear icon ("Settings").
In the settings menu, select the section Network and InternetNext, tap "Wi-Fi." Make sure the Wi-Fi switch is turned on. Find your network in the list, tap it, and select "Forget" (if the network is saved) or simply enter the password (if the network is new).

Settings → Network & Internet → Wi-Fi → [Your network] → Enter passwordFor voice-controlled TVs, you can try saying "Open network settings." This will speed up access to the desired menu. Once connected, the system may prompt you to update the time and date online—this is important for app functionality, right?
Solving common connection errors
Even if the data is entered correctly, technical problems may occur. One common problem is the wrong encryption type. The router may be operating in encrypted mode. WPA3, which older TVs don't support. In this case, you need to go to the router settings (via a computer or phone) and switch the security mode to WPA2-PSK.
Another common error is an overflowing DHCP client list. If there are many devices in the house, the router may simply not assign an IP address to the TV. Solution: reboot the router by unplugging it for 10-15 seconds.
The table below will help you diagnose the problem based on the error code or message:
| Error message | Probable cause | Solution method |
|---|---|---|
| Incorrect password | Error in symbols or case | Check CapsLock, retype using "Show Password" |
| Not found | Weak signal or hidden SSID | Move closer to the router and check the network visibility. |
| Limited | Problem with obtaining IP | Reboot your router and set up a static IP address on your TV. |
| Unable to connect | Incompatibility of standards | Change the Wi-Fi channel on the router (1, 6, 11) |
If your TV sees a 5 GHz network but doesn't connect, it may not support that band. Try connecting to a 2.4 GHz network, which usually has the same password but a different name (without "5G" at the end).
Reset network settings and factory reset
If all else fails, the only other option is to reset your network settings. In the TV menu (under "General" or "System"), find "Reset Network Settings." This will delete all saved Wi-Fi profiles and Bluetooth settings, but will not affect your apps or accounts.
In extreme cases, when a software failure blocks any changes, a full restore is performed factory resetPlease note: this will return your TV to its factory-fresh state. You'll have to reconfigure channels and sign in to your Netflix, YouTube, and other accounts.
⚠️ Warning: A factory reset irreversibly deletes user data. Make sure you remember your streaming service logins and passwords before performing this operation.
After the reset, the TV will prompt you to go through the initial setup, where the first step is selecting a language and connecting to Wi-Fi. Enter the new password carefully, as this will be a clean system configuration.
How to perform a hard reset without a menu?
If the menu doesn't open, locate the power button on the TV body (not on the remote). Press and hold it for 10-15 seconds until the logo appears. On some models, this initiates a reset or enters the service menu.
Frequently Asked Questions (FAQ)
