The situation when the landline internet suddenly disconnects or the signal quality in the room with the TV leaves much to be desired is familiar to many owners of smart devices. In such moments, the built-in Smart TV Apps stop working, blocking access to your favorite movies and streams. However, there's an effective solution that allows you to continue watching without interruption: using your smartphone as a hotspot. Wi-FiThis method turns your mobile Internet into a full-fledged home network, accessible to LG Smart TV.
Connecting a TV LG Connecting your phone to a wireless network is technically not much different from connecting to a regular home router, but it does have its own important nuances. The focus here is not so much on the pairing process as on signal stability and data usage. Mobile operators often limit the speed or data volume when sharing internet, so it's worth checking your plan before beginning setup. This will help avoid unpleasant surprises such as blocked access or reduced speeds.
In this guide, we'll detail the process of activating modem mode on various operating systems and then setting up your TV. You'll learn how to correctly set the signal frequency, select a secure encryption protocol, and optimize settings for watching high-definition video. Following these simple rules will allow you to quickly establish a connection and enjoy content even without a wired internet service provider.
Preparing your smartphone for Internet sharing
The first and most important step is to properly configure your mobile device, which will act as a router. The process of activating the access point may vary slightly depending on the operating system version, whether it's Android or iOSIn both cases, you need to make sure your phone's mobile data is enabled and you have a strong network signal. Without this step, the TV LG will be able to connect to the phone, but will not have access to the network.
For users Android The path to settings usually lies through the "Settings" menu, where you need to find the "Connections" or "Network & Internet" section. Within this section, the desired function is often called "Access point & tethering" or "Mobile hotspot." It is important to set up the network name in advance (SSID) and create a secure password to prevent neighbors from connecting to your internet without permission. Modern smartphones also allow you to select the frequency range, which is critical for compatibility with older TV models.
iPhone owners need to go to the section Settings → Cellular → Personal HotspotHere you need to activate the "Allow others" switch. Devices Apple automatically create a secure network using your Apple ID name or the name specified in the main settings. Pay special attention to the "Maximum Compatibility" setting if your TV LG Doesn't see the network or can't connect to it. This setting switches the access point to the 2.4 GHz frequency, which is supported by almost all devices.
⚠️ Please note: Some mobile operators block or charge separately for data traffic shared via a hotspot. Before activating tethering, check your plan's terms in your operator account to avoid unexpected charges.
Step-by-step setup of your LG TV
Once the smartphone's access point is active and broadcasting a signal, you can proceed to setting up the TV itself. Operating system interface webOS, installed on most modern models LG, is intuitive, but requires careful input. To begin, take the remote control and press the gear button or the Settingsto get to the main settings menu.
In the menu that opens, select "Network" or "All Settings," then "Wi-Fi Connection." The TV will begin scanning for available wireless networks within range. In the list that appears, find the network name you set on your smartphone. If the name doesn't appear immediately, try refreshing the list or moving your phone closer to the TV to strengthen the signal.
After selecting the desired network, the TV will ask for a password. Enter the character combination you set when setting up the hotspot on your phone. Be careful when entering the password: letter case is important, and even a single character error will result in connection failure. After successful authorization, a message will appear on the screen confirming the connection has been established, and the TV will begin checking for software updates.

Troubleshooting 2.4GHz and 5GHz Bandwidth Issues
One of the most common reasons why a TV LG The reason why your smartphone doesn't see the network is because of frequency band incompatibility. Most modern smartphones create an access point in the frequency band by default. 5 GHz, which provides high speed but has a shorter range and is not supported by all TV models, especially those released several years ago. Older Wi-Fi modules in TVs LG often operate exclusively in the 2.4 GHz range.
If you are faced with a situation where your phone is distributing the network, but your TV simply “doesn’t notice” it, you need to force the access point to switch to the 2.4 GHz frequency. Android This is done in the advanced access point settings, where you need to select "AP Band" and set it to 2.4 GHz. On iPhone, this feature is called "Maximum Compatibility" and also switches the device to an older, but universal standard.
Why is 5GHz faster but less compatible?
The 5 GHz band is less congested with neighboring routers and Bluetooth devices, ensuring a more stable data flow. However, its range is significantly shorter and it penetrates walls less effectively, which can be critical if your phone is in another room.
After changing the band, it's recommended to reboot the hotspot on your phone by turning it off and on again. Then, try scanning for networks on your TV again. LGIn 90% of cases, this resolves the visibility issue. If the connection still isn't there, it's worth checking if your phone has a limit on the number of connected devices, although this is rarely an issue with a single TV.
Compatibility and characteristics table
For your convenience, we've prepared a summary table to help you quickly navigate the settings depending on your smartphone type and TV model. This information is based on the standard Wi-Fi module operating parameters in these devices. LG and mobile operating systems.
| Parameter | 2.4 GHz band | 5 GHz band |
|---|---|---|
| Compatibility with LG TVs | High (all models) | Average (models after 2015) |
| Maximum speed | Up to 150-300 Mbps | Up to 800+ Mbps |
| Range | Up to 30 meters | Up to 10-15 meters |
| Stability in the apartment | Low (a lot of interference) | High (less noise) |
Use this table as a reference when choosing access point settings. If your TV LG It supports both bands, but if you plan to watch 4K video, it's best to use the 5 GHz band by placing your phone as close to the receiver as possible. For regular terrestrial TV or YouTube in Full HD, the slower but longer-range 2.4 GHz band is perfectly sufficient.
Optimizing traffic consumption and speed
Using mobile internet for Smart TV is associated with high traffic consumption. Modern streaming services, such as Netflix, YouTube or iviBy default, they tend to set the image quality to maximum, which can quickly deplete your data plan. One minute of watching 4K video can consume up to 50 MB of data, making playback quality control a top priority.
To avoid problems, we recommend manually limiting video quality in the app settings on your TV. Go to the settings for a specific video service, find the "Video Quality" or "Data Transfer" section, and select "Data Saver" or a fixed resolution, such as 720p or 1080p. This will significantly reduce bandwidth usage and extend your viewing time.
⚠️ Note: Disabling automatic updates for apps and the TV operating system LG Mobile network mode is a mandatory step. The firmware update can be several gigabytes in size and will occur in the background unless you block downloads over mobile networks.
It's also worth keeping in mind that mobile internet speeds can fluctuate depending on the load on the carrier's tower. If a video is constantly buffering, try lowering the quality to 480p or pausing playback for a couple of minutes to allow the buffer to refill. Keep in mind that using hotspot mode actively drains battery power and heats up your phone, so it's best to keep it connected to a charger.
Alternative ways to connect content
If setting up a hotspot seems too complicated or your mobile network data usage is too high, there are alternative ways to stream images from your phone to your TV. LG, which do not require connecting the TV itself to the Internet. Technology Screen Share (or Miracast) allows you to broadcast your smartphone's screen image directly to your TV via a local Wi-Fi network created by the TV itself or via Wi-Fi Direct.
For iPhone owners, the technology is relevant AirPlay 2, built into many new models LGIt allows you to stream video from apps or your entire phone screen to your TV without having to connect the TV to the same Wi-Fi network as your phone, as long as you use the direct connection feature. However, some online services may still require both devices to be on the same network, which brings us back to the need for an access point, but for signal transmission rather than for the TV to download content.
Another option is to use a USB cable. If you have movies downloaded on your phone, you can connect them directly to the TV's USB port. LGIn this case, the TV will recognize the phone as an external storage device, and you can play videos through the built-in media player without any internet connection. This is ideal for watching heavy content at high bitrates.
Frequently Asked Questions (FAQ)
Why does my LG TV say "No Internet access" even though I'm connected to Wi-Fi?
This means the connection between your phone and TV is established, but the phone isn't transmitting data. Check that mobile data is enabled on your smartphone (4G/LTE/5G icon). Also, make sure your phone isn't in "Data Saver" mode for your hotspot or has background data restrictions.
Does the phone get very hot when working in modem mode?
Yes, using hotspot mode puts a lot of strain on the smartphone's processor and communication module, which leads to increased heat. It's recommended to remove the phone's case while browsing and, if possible, keep it on a hard surface or connect it to an external fan/cooler.
Is it possible to watch 4K video using my phone's hotspot?
Technically, this is possible if your plan allows it and your 4G/5G signal is very strong and stable. However, in practice, mobile internet is often unstable for 4K streaming, resulting in constant buffering pauses. For 4K, it's best to use local files or reduce the quality to Full HD.
Will voice search work on TV via phone?
Voice control of the TV interface can work, as commands are processed locally or require minimal traffic. However, voice search within apps (for example, searching for videos by voice on YouTube) requires transmitting audio data to the server, which will only work with an active internet connection via an access point.
