When your home Wi-Fi router suddenly shuts down or your ISP is performing maintenance, it can catch you off guard while you're watching your favorite show. Fortunately, modern smartphones are powerful enough to temporarily replace your router and ensure stable connection For your multimedia system. LG owners often wonder if their Smart TVs can be connected to the internet using mobile data, and the answer is a resounding yes.
There are several proven methods for establishing a connection between a mobile device and a TV, each with its own technical considerations. You can create a full-fledged hotspot, use a direct Wi-Fi connection, or stream content through dedicated apps. Selecting a specific method It depends on your smartphone model, the version of the WebOS operating system, and the goals you are pursuing.
In this article, we'll take a detailed look at all the nuances of traffic transfer so you can quickly restore access to online cinemas and streaming services. We'll cover both standard methods and specific settings that will help optimize speed. The key is to understand that mobile Internet has its own limits, so its use requires more careful attention to traffic consumption.
Creating a Wi-Fi hotspot on your smartphone
The most versatile and reliable way to turn your phone into a full-fledged router is to activate tethering mode. This feature is built into the core of Android and iOS operating systems, allowing you to stream 4G/5G mobile signal to other devices. For an LG TV, this looks like a regular home network, to which it connects in the standard way.
The setup process on Android devices may vary slightly depending on the manufacturer's operating system, but the logic remains the same. You need to find the section responsible for network connections and activate the personal hotspot function there. It's important to set a strong password right away to prevent neighbors from connecting to your device. communication channel and consume your traffic.
On Apple devices, the process is even more simplified and integrated into the ecosystem. Simply go to Settings and enable Personal Hotspot, after which your iPhone will be visible to other devices. Keep in mind that if you're actively using your TV, you'll need to enable Personal Hotspot. battery charge The smartphone's battery will be drained much faster, so it is recommended to keep it charged.
Once you activate the mode on your phone, the process on your TV becomes trivial. Simply go to the network settings, find your smartphone's name in the list of available networks, and enter the password. After successful authorization, all apps on Smart TV will have access to the global network through your mobile channel.
Connecting LG Smart TV to a mobile network
Once your phone's hotspot is active, you need to properly configure the signal receiver. LG TVs' webOS interface is user-friendly, but it does have its own navigation nuances. First, grab the remote and press the settings button, often labeled as a gear or Settings.
In the menu that opens, find the section responsible for network connections. It's usually called "Network." Within this section, select "Wi-Fi" as the connection type. The TV will scan the airwaves and, after a few seconds, display a list of available networks, including your smartphone's name.
Select the desired network from the list. If you completed the phone setup process correctly, the system will prompt you for a password. Use the on-screen keyboard to enter the passkey. Once entered, tap "Connect" or "OK." The TV will attempt to connect to LG servers to check the status.
☑️ Checking the connection to the access point
A successful connection will be confirmed by a corresponding message on the screen, and a Wi-Fi icon will appear in the corner of the interface. Now your Smart TV Ready to use the internet. If the connection fails, try resetting the Wi-Fi module on your TV by turning it off and then on again in the settings.
Using Wi-Fi Direct technology
An alternative option that doesn't require a traditional hotspot with internet access for all devices is Wi-Fi Direct. This protocol allows devices to connect directly to each other, bypassing the router. However, it's worth noting an important caveat: to fully utilize internet services on your TV using this method, your phone must support the feature. traffic relay, which is not available on all models.
With LG TVs, Wi-Fi Direct is often used to stream multimedia content (photos, videos) from a phone to the big screen without loss of quality. However, if your goal is to specifically give the TV network access, this method works in a specific way. On some Android smartphone models, you can create a Wi-Fi Direct group to which the TV connects, and then share the internet connection through this group.
To set it up, go to the advanced Wi-Fi settings on your mobile device. Find Wi-Fi Direct and enable it. On an LG TV, the path is as follows: Settings → Network → Wi-Fi DirectEnable the feature and wait for the devices to discover each other.
⚠️ Note: Wi-Fi Direct is primarily designed for file and media transfer, not for internet sharing. If apps on your TV don't see the network after connecting via Wi-Fi Direct, use the classic hotspot described in the first section.
The advantage of this method is the ability to transfer large amounts of data at high speeds, since the channel isn't shared among multiple devices. However, the connection stability for video streaming may be lower than when using a standard access point. Therefore, it's better to use modem mode for watching online TV.
Screencasting and content sharing with Screen Share
If your primary goal is to display your smartphone's screen on your TV, rather than necessarily launching apps directly on your Smart TV, Screen Share is the ideal solution. LG TVs implement this technology via the Miracast protocol. It allows you to mirror the entire image from your phone's display to a larger screen.
To launch this feature on your LG TV, find the "Screen Share" or "Cast" app in the list of apps. Launch it, and the TV will enter connection standby mode. On an Android smartphone, this feature may be called "Cast," "Smart View" (on Samsung), or "Projection." On iPhones, the equivalent is AirPlay 2, which is supported by many new LG models.
Once devices are detected, select your TV from the list on your phone. The image will instantly appear on the screen. In this mode, internet traffic is consumed by your smartphone, which processes the video stream and sends it to the TV. This can be convenient if the TV app interface is slow or doesn't support the required video format.
It's important to be aware of signal latency. When streaming wirelessly, there may be a lag between what you do on your phone and what's displayed on your TV. While this isn't a deal-breaker for watching movies, it can be a problem for gaming. This mode also energy consumption phone increases many times over.
Why does the picture flicker when I broadcast my screen?
A choppy picture during Screen Share is most often caused by Wi-Fi congestion or a weak signal. Try moving closer to the router (if you have one) or reducing the number of active devices on the network. Lowering the streaming quality in your phone's settings can also help.
Problems with connection speed and stability
When using a phone as a router, users often experience slow download speeds or video buffering. This is due to the physical limitations of mobile internet and the specifics of wireless data transmission. Speed depends on the cell tower signal strength, network congestion, and the operator's data plan.
Another factor affecting performance is the distance between the phone and the TV. Although Wi-Fi signals penetrate walls, concrete floors and metal structures can significantly weaken them. For stable performance, it's recommended to place the smartphone close to the TV, preferably within line of sight.
It's also worth considering that modern 4K videos require a very high bitrate. Mobile networks may not be able to handle such a data stream, especially if the signal is unstable. In this case, it's advisable to reduce the playback quality in the app settings (for example, YouTube or Netflix) to 1080p or 720p.
| Parameter | Description of influence | Recommendation |
|---|---|---|
| Signal level | A weak signal reduces speed and increases ping. | Place your phone near a window or higher |
| Number of devices | Many connected clients share the channel | Disconnect unnecessary gadgets from the access point |
| Frequency range | 2.4 GHz has a longer range, 5 GHz is faster | Use 5 GHz for video, 2.4 GHz for text |
| Background processes | Phone updates are eating up your data. | Disable automatic app updates on your phone |
Traffic consumption and data savings
Watching TV over mobile internet can quickly deplete your data plan. High-definition video content consumes a huge number of megabytes. One hour of watching 4K video can consume up to 7-10 GB of data, a significant portion of the standard monthly data allowance.
To avoid unpleasant surprises like blocked internet or additional charges, it's important to monitor your data usage. Most smartphones allow you to set a data limit in the hotspot settings. Once the specified amount is used, internet sharing will automatically stop.
Many streaming services also have a "Data Saver" feature or allow you to manually select video quality. When connecting via a mobile network, always select a lower quality setting unless you're sure your plan offers unlimited data. This will allow you to watch your favorite shows longer without the risk of losing connection.
Keep in mind that the TV itself can also consume data in the background: updating apps, syncing the time, and sending telemetry. Therefore, after you finish watching, we recommend turning off Wi-Fi on the TV or completely disabling the hotspot on your phone.
