Modern Smart TV Systems require a stable internet connection to function correctly, but a wired connection isn't always possible, or the main home router is too far away. In such situations, the smartphone internet sharing feature comes to the rescue, turning your mobile device into a fully-fledged Wi-Fi routerThis solution allows you to instantly establish a connection between your gadget and TV. LG without unnecessary equipment.
The process of creating an access point on Android or iOS It only takes a couple of minutes, but requires attention to details such as frequency band and security type. Many users encounter difficulties precisely when setting up network visibility or choosing a password, which leads to connection errors. In this guide, we'll walk you through every setup step so you can enjoy content on your big screen without lag.
Using mobile data to watch high-definition videos can be expensive, so it's important to understand how to optimize your data usage. It's also worth considering that some carriers limit the speed or data volume when sharing internet with other devices. We'll cover the technical details that will help you avoid connection issues and ensure maximum performance from your network.
Preparing your smartphone and checking your tariff plan
Before you start setting up access points, you need to ensure that your smartphone supports modem functionality and has an active internet connection. Most modern data plans include a certain data limit that is divided among all connected devices, so it's important to check your carrier's terms in advance. Uncontrolled internet sharing can quickly deplete your data plan or reduce speed after reaching the limit.
Make sure your phone's mobile data is enabled and the cellular signal is strong enough to transmit the video stream. Weak signal 4G/LTE will cause constant video buffering on your TV LG, even if the device itself is technically sound. It's recommended to run a speed test using your smartphone's browser before setting up the TV.
It's important to note that some carriers may block or restrict the protocols used for internet tethering, especially on unlimited plans. If you plan to frequently use your phone as a router, it's worth checking with your provider to see if any such restrictions exist.
⚠️ Attention: Some tariff plans with the "Unlimited Internet" option may automatically reduce speed to 64-128 kbps after exceeding the 3-10 GB limit while using modem mode. Check the terms of your contract to avoid any unpleasant surprises.
Setting up a hotspot on Android devices
The process of activating the modem mode on devices running Android The process may vary slightly depending on the operating system version and the manufacturer's shell (Samsung, Xiaomi, Huawei). However, the general procedure remains the same for most models. You'll need to go to the wireless network settings and find the corresponding section.
Open the menu Settings and select the item Connections or Network and Internet. Find the section Access point and modem (sometimes called "Tethering" or "Personal Hotspot"). Click on it to open the detailed settings.
- 📱 Tap the "Wi-Fi hotspot" switch to activate the hotspot mode.
- 🔒 Select "Configure Access Point" to change the network name (SSID) and password.
- 📡 In the "Band" section, select your preferred frequency (2.4 GHz or 5 GHz).
- 🔐 Make sure the security type is selected WPA2 PSK for reliable protection.
Particular attention should be paid to the choice of frequency range. If your TV LG released a few years ago, it may not support the standard 5 GHz, in which case you need to force the smartphone to switch to 2.4 GHz mode. Ignoring this is the most common reason why the TV simply doesn't see the network created by the phone.
After configuring the settings, save your changes. Your smartphone is now broadcasting a Wi-Fi signal, ready to connect to external devices. Don't turn off your phone's screen completely if the battery is low, as some models may disable the hotspot to save power.
Instructions for iPhone (iOS) owners
For device owners Apple We're lucky with the simplicity of the interface, where the Personal Hotspot feature is deeply integrated into the system and works reliably. To get started, make sure cellular data is enabled on your iPhone. Go to Settings and select the item Modem mode.
Activate the switch "Allow others"The system will automatically generate a network name and password, which can be changed by clicking on the corresponding field. For TVs LG It is recommended to use a password consisting only of letters and numbers, without special characters, to avoid input errors with the remote control.
An important feature of iOS is the ability to connect via Bluetooth or USB, but for TV we need exactly Wi-FiMake sure "Maximum Compatibility" is enabled if you have an iPhone 12 or later. This option switches the network to the 2.4 GHz band, which is critical for older Smart TVs.
Why might my iPhone not allow me to turn on Personal Hotspot?
Sometimes your carrier blocks this feature at the profile level. Solution: Contact your carrier's support or create a new APN profile with the correct access point settings.
The iOS interface also lets you see the number of connected devices in real time. This is convenient for monitoring: you'll know whether your TV is connected or if someone else is trying to use your data plan.
Connecting an LG TV to the created network
Once the hotspot on your smartphone is activated, move on to the TV's settings. Take the remote control. LG Magic Remote or a standard remote control and press the button Settings (gear) or button Smart to enter the main menu.
Depending on the operating system version webOS, the path may look different. Typically it is: Settings (gear) → All settings → Network → Wi-Fi connectionMake sure the Wi-Fi module on your TV is turned on.
The TV will begin searching for available networks. You should see the name (SSID) you set on your smartphone in the list. Select it. If the network is hidden, select "Enter network name manually" and enter the name exactly, taking care to ensure proper case-inclusion.
- 📺 Find your network in the list by name (SSID).
- 🔑 Enter your password using the on-screen keyboard.
- ✅ Click "Connect" or "Done" to complete the process.
- 🌐 Wait for the connection icon to appear and the internet check to complete.
If the password is entered correctly, the TV will establish a connection and will likely prompt you to update the software or synchronize the time. This is a good sign that the internet is working correctly.
⚠️ Attention: When entering a password on a TV, it's very easy to make a mistake due to small font or a clumsy remote control. Carefully check each letter, especially if the password contains similar characters (0 and O, 1 and l).
☑️ Connection check
Comparison of frequency ranges and selection of the optimal one
Choosing between 2.4 GHz and 5 GHz frequencies is key to connection stability. New-generation smartphones default to the 5 GHz band, which offers high speeds but has a shorter range and poorer penetration through walls.
Old TV models LG (manufactured before 2015-2016) are often equipped with Wi-Fi modules that only operate in the 2.4 GHz band. In this case, they will physically be unable to "see" a network created in the 5 GHz band, even if the password is correct.
| Parameter | 2.4 GHz band | 5 GHz band |
|---|---|---|
| Transfer speed | Up to 150-300 Mbps | Up to 800+ Mbps |
| Range of action | High (up to 50 m) | Medium (up to 20 m) |
| Penetration ability | Good | Low |
| Compatibility with LG TV | 100% (all models) | Only new models (4K, OLED) |
If you're watching 4K HDR video, 5 GHz is preferable, but only if the TV is in the same room as your smartphone. For regular Full HD content and social media, the 2.4 GHz band is more than sufficient and provides a more stable signal.
Solutions to common problems and errors
Even with proper setup, situations may arise where the TV displays "No internet connection" or endlessly attempts to obtain an IP address. First, try resetting the Wi-Fi module on your TV: turn it off and then back on in the network settings.
A common issue is an IP address conflict or a DHCP table overflow on your smartphone. Try disabling the hotspot on your phone, waiting 10 seconds, and then re-enabling it. Deleting the network on your TV (forgetting the network) and re-entering the password also helps.
If the issue persists, check the date and time settings on your smartphone. Incorrect time can cause security certificate errors, causing the TV to reject the connection, believing it to be unsecure.
- 🔄 Restart both devices (smartphone and TV).
- 🗑️ Delete the network profile on your TV and create a new one.
- 📅 Check that the date and time on your smartphone are correct.
- 📶 Make sure that the "Data Saver" mode is not enabled on your phone.
In rare cases, resetting the network settings on the TV itself to factory defaults can help. This won't delete your apps, but it will return the network settings to their original state, which often resolves software issues.
⚠️ Attention: Operating system interfaces webOS, Android And iOS are constantly updated. The menu item locations may differ from those described. If you can't find the item you need, use the search in the settings or refer to the manufacturer's official documentation.
