Changing your home wireless network password is a standard security procedure that every smart home owner faces sooner or later. When you change the access key on your router, your LG TV The device stops connecting to the internet because it continues to try to use old login credentials. This makes it impossible to launch streaming services, update software, or use Smart TV features.
The process of updating your credentials can be confusing due to the interface of the webOS operating system installed on most modern models. You'll need to go through the connection process again, first deleting the saved network from the device's memory. In this article, we'll cover all the nuances of this procedure for different firmware versions.
Sometimes the system may not allow you to change settings immediately, requiring a full reset or reboot of the module. Understanding the logic of the network module LG This will help you avoid unnecessary steps and quickly restore access to online content. We'll cover both standard menu-based methods and troubleshooting possible connection errors.
Preparing to change network settings
Before setting up your TV, make sure your router has already been reconfigured and is sharing the network with a new password. If you're planning to change the security key, it's best to do so when the TV is turned off or disconnected from the network to avoid IP address conflicts. It's important to have your remote control handy, as navigating this menu with a mouse or smartphone is often unavailable.
Check that the Wi-Fi indicator on your router is lit and that your network is visible from other devices, such as your smartphone. This will rule out problems with the router itself. It's also a good idea to write down the new password in a note or keep it readily available, as entering long characters using the remote can be tedious and prone to errors.
⚠️ Important: If you are using a guest network or a network with MAC address filtering, make sure that your TV's address is added to the router's whitelist; otherwise, even the correct password will not help.
Make sure the remote is working properly and the batteries are not dead, as you will have to navigate the on-screen keys a lot. Some models Magic Remote controls may require re-pairing after a long period of inactivity or a power reset of the TV.
Deleting a saved Wi-Fi network
The first and most important step is to delete the old network profile from the TV's memory. System webOS It won't allow you to simply "overwrite" the password for an active network; it requires creating a new connection. To do this, press the settings button on the remote (the gear icon) and go to All settings.
In the menu that opens, select a category Net or Connection, and then go to the item Wi-Fi connectionHere you'll see a list of available networks and the one your TV is currently connected to or has previously attempted to connect to. Select your network and find the option Delete network or Forget the network.
☑️ Preparing for reconnection
After confirming the deletion, the network will disappear from the list of saved networks. The TV now sees it as a new, unknown access point. This is a critical step, as attempting to enter the password without first deleting it often results in cyclical authorization errors.
If the delete button is grayed out or hidden, try temporarily disabling the Wi-Fi module using the slider in the same menu and then re-enabling it. Sometimes, completely signing out of your LG Service account helps if the TV requires authorization for network changes, although this is rare for basic settings.
Step-by-step instructions for connecting with a new password
Once the old profile is deleted, the connection process becomes standard. In the same menu Wi-Fi connection Click on the list of available networks. Find your home network name (SSID) in the list. If you have hidden the network name on your router, select the option Add a hidden network and enter the name manually.
When you select a network, a virtual keyboard will open. Be careful here: letter case is important. Use the navigation buttons to switch between numbers, lowercase and uppercase letters, and special characters. After entering the password, press Connect.
| Interface element | Function | Location |
|---|---|---|
| Gear | Enter settings | Upper right corner or remote control button |
| Wi-Fi | Enabling the module | Network / Connection menu |
| Additional settings | Editing IP/DNS | Below the list of networks |
| OK / Enter | Confirm your choice | Center of the remote control |
| Back | Return/Delete character | The back button on the remote control |
| QWERTY | Change the layout | On-screen button |
If the password is entered correctly, the TV will begin the process of obtaining an IP address. The screen may flash or a notification about a successful connection will appear. The network status will change to Connected, and a signal strength icon will appear next to the network name.
If you encounter an error, check to see if you've mixed up any symbols, such as zero and the letter O, or one and the letter I. Also, make sure your router doesn't have access time filtering enabled, which could block the device while attempting to connect.
What to do if the keyboard does not appear?
If the on-screen keyboard doesn't appear or is frozen, try restarting your TV by completely unplugging it from the power outlet for 1-2 minutes. This will clear the webOS interface cache.
DNS settings and advanced options
Sometimes, after changing the password, the TV connects to the router but cannot access the internet. In this case, you may need to manually configure the DNS servers. Go to Additional Wi-Fi settings and uncheck the box Automatically.
In the DNS fields, enter the addresses of reliable servers, for example, from Google (8.8.8.8) or Cloudflare (1.1.1.1). This often helps resolve issues accessing the LG Content Store or streaming services.
You can also check the device's IP address in the advanced settings. Make sure it's on the same subnet as your router (usually the first three digits of the address are the same). If the address starts with 169.254..., this means that the TV did not receive an address from the router, and the problem lies in the compatibility of encryption protocols.
⚠️ Note: The menu interface may differ depending on the webOS version (3.0, 4.0, 5.0, 6.0, and later). The layout of the items may change, but the logic remains the same.
Don't change MAC address settings unless you're an advanced user and understand why you need to do so. Cloning a MAC address may only be necessary in specific cases of ISP access restrictions.
Solving common connection errors
One of the most common problems is the "Unable to connect to the network" message or an endless password verification loop. This is often due to the TV trying to use an old security protocol while the router has already switched to a new one (for example, from WPA2 to WPA3). Try temporarily lowering the security level on your router to WPA2-PSK (AES).
Another cause is a full DHCP client list on the router. If you have many devices, the router may not assign a new IP address to the TV. Restarting the router usually resolves this issue by releasing old address leases.
If the TV LG If your device sees the network but won't connect, try changing the Wi-Fi channel on your router. Channels 1, 6, and 11 are considered the least noisy in the 2.4 GHz band. For the 5 GHz band, select channels 36, 40, or 44.
In rare cases, resetting network settings to factory defaults can help. To do this, find the item in the network menu. Network reset or Reset Wi-FiThis action will delete all saved networks and passwords, returning the module to its original state.
Using the WPS function to simplify
If entering a password from the remote control seems too complicated or causes errors, you can use technology WPS (Wi-Fi Protected Setup). This method allows you to connect your TV to your router without entering a key, simply by pressing a button. Look for the WPS button on the router.
In the LG TV menu, go to the Wi-Fi settings and select the option Connecting via WPS-PBCAfter selecting this option, you'll have about 2 minutes to press the physical button on the router. The devices will find each other and exchange encryption keys automatically.
This method is especially convenient if you have a complex password with many special characters that is difficult to enter using the on-screen keyboard. However, keep in mind that WPS is considered a less secure method, as it is vulnerable to certain types of brute-force attacks.
Make sure WPS is enabled in your router's settings. Some router models require you to enable it first through the admin web interface.
