Modern Smart TV It's impossible to imagine life without constant access to the global network, but often the built-in wireless module in a TV is unstable or the signal is too weak. In such situations, device owners LG People are looking for alternative ways to ensure a stable data stream for streaming high-definition movies. Using a smartphone as a hotspot is an ideal solution when the router is far away or temporarily down.
This technology allows you to turn 4G or 5G mobile Internet into a full-fledged Wi-Fi network, which can be connected not only to a laptop, but also to TVThe setup process does not require deep technical knowledge, but it does have its own nuances, especially when working with the operating system. webOS, installed on most modern LG models. It's important to understand that picture quality directly depends on your mobile connection speed.
In this article, we'll cover all the steps for creating an access point, how to connect your TV, and any potential limitations you may encounter. We'll cover both standard methods using system settings and specialized features for streaming content. Properly configured settings will ensure maximum data transfer speeds and minimize latency when viewing video.
Preparing your smartphone for modem mode
Before attempting to connect devices, you need to make sure your smartphone is properly configured for data sharing. This process is standardized on modern Android devices and iPhones, but the menu item names may differ depending on the operating system version and the manufacturer's user interface. First, check your mobile account balance and ensure that you have enabled data sharing. mobile Internet.
For owners of devices based on Android You should go to Settings and find the section responsible for network connections. It's usually called "Connections," "Network & Internet," or "Access Point & Modem." This is where you'll find key settings that need to be changed before connecting the TV. Pay attention to the security standard, which by default may not be compatible with older TV models.
- 📱 Go to Settings and select "Wi-Fi hotspot" or "Tethering & portable hotspot".
- 🔐 Set a strong password using WPA2 PSK characters for maximum compatibility.
- 📡 Check the frequency range: for LG TVs, it is better to choose 2.4 GHz, as 5 GHz may not be supported.
- 👁️🗨️ Activate the "Hide device" option if you want the network to be visible only when you manually enter a name.
Particular attention should be paid to the frequency range. Many modern smartphones create a network in the frequency range by default. 5 GHz, which provides high speed but has a shorter range and poor penetration. LG TVs, especially older models, may simply "not see" this network, so switching to 2.4 GHz often solves the connection issue.
⚠️ Please note: When you activate a hotspot on your smartphone, the Wi-Fi receiver is automatically disabled. This means you won't be able to share the internet and surf the web simultaneously via Wi-Fi on your phone; you'll only be able to use mobile data.
Step-by-step instructions for connecting an LG TV
After successfully activating the modem mode on your smartphone, you can proceed to setting up the TV itself. Interface webOSThe remote control used in LG TVs is intuitive, but navigating with the Magic Remote requires some practice. Make sure the remote is paired with the TV and the on-screen cursor responds to movement.
To get started, you need to access the main settings menu. Press the gear button on the remote control. In the menu that appears, select "All Settings" or go directly to the "Network" section if it's a quick access option. This is where we'll need to enable the wireless connection.
☑️ Preparing for connection
In the networks menu, select "Wi-Fi connection." The TV will automatically scan for available networks within range. You should see the name (SSID) you set on your smartphone in the list. If the network is hidden, select "Add hidden network" and enter the name manually. After selecting the network, enter the previously set password using the on-screen keyboard.
| Parameter | Recommended value | Description |
|---|---|---|
| Frequency range | 2.4 GHz | Provides better compatibility with older TV modules |
| Security type | WPA2-Personal | Standard encryption protocol for home networks |
| IP address | Automatic (DHCP) | The phone itself will give the address to the TV |
| DNS | Automatically | Mobile operator servers are used |
After entering the password, the TV will attempt to establish a connection. If all parameters are entered correctly, you will see a message indicating a successful connection, and the Wi-Fi icon will appear in the top corner of the screen. Now your Smart TV has internet access through your mobile phone's data connection. Speed will depend on the cellular signal strength in your area.
Using Screen Share and Miracast
Sometimes users need to do more than just give their TV internet access, but also directly stream their smartphone's screen content. LG TVs use this technology for this purpose. Miracast, which may be called "Screen Share" in the menu. This method differs from simple Wi-Fi sharing in that it creates a direct wireless connection between devices to transmit the video stream.
To start casting, press the Enter button on your TV remote or find the "Screen Share" shortcut in the app list. A connection waiting menu will appear on the screen. At this point, the TV will create its own network or become visible for search. On your smartphone, you'll need to activate the "Cast," "Smart View," or "Screen Mirroring" feature in the notification shade.
The smartphone will search for available devices, and your TV should appear in the list. LGAfter selecting a device, a connection confirmation prompt may appear on the TV screen, which you'll need to accept with the remote. It's important to note that when using Miracast, your phone's internet connection may switch to the Wi-Fi streaming channel, which can sometimes interrupt access to online video.
⚠️ Please note: When sharing your screen via Miracast, the image may be delayed or have artifacts if your phone's processor is overloaded or the Wi-Fi signal is unstable.
To watch online movies, it's better to use built-in apps on a TV connected to a hotspot rather than mirroring your screen. This will reduce the strain on your smartphone's battery and ensure more stable picture quality, as the TV's processor, not your phone's, will handle video decoding.
Setting up a USB modem for a wired connection
If your wireless connection is unstable or your TV's Wi-Fi module is faulty, you can use a USB cable to share your internet connection. This method is called USB modem and allows data to be transmitted directly through the port, eliminating signal loss over the air. This is especially important for LG models with sensitive Wi-Fi modules.
To implement this setup, you'll need a high-quality USB cable that can transfer data, not just charge your device. Connect one end of the cable to your smartphone and the other to the USB port on your LG TV. In your phone's hotspot settings, select "USB tethering" instead of "Wi-Fi hotspot."
Settings → Connections → Hotspot & Tethering → USB Tethering (switch to active)The TV should automatically recognize the new network connection. In the network menu webOS A notification may appear indicating a USB connection. The advantage of this method is the absence of radio interference and a more stable ping, which is critical for online gaming or watching 4K video. However, the phone's battery will drain quickly, as the TV port draws power.
Why doesn't the TV detect the USB modem?
Not all LG TVs support USB Tethering. Typically, this feature is found on 2018 and newer models with the latest version of webOS. The issue could also be with the cable, which only supports charging.
Troubleshooting connection issues and errors
Even if all steps are followed correctly, technical difficulties may arise that prevent the network from functioning properly. One of the most common issues is when the TV detects the network and connects to it, but displays the message "No internet access." This often indicates issues with the mobile operator's DNS servers or a lack of IP addresses.
In this case, try manually entering DNS addresses in your TV's network settings. Alternatively, you can use public DNS from Google or Cloudflare. To do this, select "Advanced Settings" in the Wi-Fi settings menu and change the DNS retrieval mode from "Automatic" to "Enter Manually."
- 🌐 Primary DNS:
8.8.8.8(Google) - 🌐 Secondary DNS:
1.1.1.1(Cloudflare) - 🔄 Restart both devices after changing the settings
- 📶 Make sure that data saving mode is not enabled on your phone
Another common error is constant connection drops. This can occur when the smartphone enters power-saving mode and disables Wi-Fi. You should go to your phone's battery settings and exclude the "Access Point" app or the system hotspot process from being optimized.
⚠️ Please note: Mobile operator interfaces and plan terms are subject to change. If tethering isn't working, check your operator account to see if tethering is enabled for your plan.
The impact of Wi-Fi sharing on battery life and traffic
Using a smartphone as a router is resource-intensive. The wireless module operates in constant data transmission mode, which causes the device to heat up significantly and drains the battery quickly. Even when watching movies for extended periods, the phone can run out of battery in 2-3 hours, even when connected to a charger.
Furthermore, modern video formats consume a huge amount of data. One minute of watching a 4K video can consume up to 50 MB of data. An hour of watching in high quality can easily exceed 2-3 GB, which is a significant portion of the monthly limit for many data plans. Always monitor your data usage using the built-in counters.
To minimize risks, it's recommended to reduce playback quality in movie theater apps on your TV if your mobile internet speed doesn't allow for 4K streaming without buffering. It's often better to choose Full HD, which will stream smoothly, than to suffer through constant interruptions in the 4K stream.
Is it safe to keep a hotspot on all the time?
Extended use in hotspot mode can cause your smartphone's battery to overheat and wear out faster. It's recommended to take breaks or use a well-cooled external power source.
Is it possible to connect to a hotspot without a password?
Technically, this is possible if you disable encryption in your phone's settings, but it's strongly discouraged. Any neighbor could connect to your network and use your traffic, potentially gaining access to your data.
Why doesn't my LG TV see the 5 GHz network?
Many TV models, especially those released before 2020, are equipped with single-band Wi-Fi modules that only operate at 2.4 GHz. In this case, you'll need to force your phone to switch to 2.4 GHz mode.
How to increase internet distribution speed?
To increase speed, try placing your phone near a window or in a location with the best cellular signal. Disabling background apps on your smartphone, which can consume bandwidth, also helps.
Does Wi-Fi hotspot work if my phone's balance is low?
No, you need active mobile data to share your internet. If your balance is empty or your data plan is exhausted, the hotspot will turn on, but no data will be transmitted to your TV.
