Every owner of modern technology is familiar with the experience of losing internet connection or suddenly losing a reliable signal from their router. In such moments, the urgent need arises to stream content to a large screen using only mobile data. Connecting an LG TV to Wi-Fi via a phone — this is not just a temporary solution, but a fully-fledged function that allows you to turn your smartphone into a powerful router or media server.
Modern Smart TV based on the platform webOS They offer a wide range of networking tools that are often underutilized. You can use your gadget not only as an access point, but also as a remote control, a password keyboard, and even an external drive for video files. Understanding these mechanisms will allow you to enjoy your favorite movies in high definition even without a traditional home network.
In this guide, we'll take a detailed look at all available methods for establishing a wireless connection between a mobile device and a TV. We'll cover the technical nuances of data distribution, data protocol settings, and speed optimization methods for comfortable, lag-free streaming.
Technical aspects of distributing the Internet from a mobile device
Before you begin setting things up, it's important to understand the physical nature of the process. When you say "share Wi-Fi," your smartphone is actually creating a local wireless network, acting as a hosta or access points (Hotspot). The TV is in this connection client, which receives an IP address from the phone and through it accesses the external network.
The main limitation lies in the bandwidth of the connection and mobile operator tariffs. While low speeds are sufficient for watching news, streaming 4K video requires a stable, high-bandwidth connection. Wi-Fi 5 GHz, supported by most modern flagships, provides significantly lower latency compared to the 2.4 GHz band.
⚠️ Please note: When actively using tethering, your smartphone's battery heats up and drains significantly faster. It is recommended to keep your device connected to a charger or use an external power bank during extended browsing sessions.
Additionally, it's important to consider the specifics of traffic compression by telecom operators. Some providers may limit speeds when torrent traffic or video streams are detected, which directly impacts picture quality on the TV screen. encrypted channel (HTTPS) In apps, it can sometimes help bypass basic provider restrictions, but it doesn't guarantee complete anonymity.
Setting up a hotspot on Android for LG Smart TV
The process of converting a smartphone based on Android Setting up a router is fairly simple, but requires attention to detail. Interfaces may vary depending on the manufacturer's interface (MIUI, OneUI, ColorOS), but the steps are the same. Open Settings, find the "Connections" or "Network & Internet" section, and select "Access Point & Modem."
Within the access point settings menu, you should set the network name (SSID) and a strong password. It is important to select a security standard. WPA2-PSK or WPA3, as older protocols may not be supported by newer LG TVs, which will result in connection errors. Also, check the frequency range: for TVs located in the same room as the phone, 5 GHz is best.
Once the hotspot is activated, a notification will appear on your phone's screen indicating the number of connected devices. On your LG TV, go to Settings → Network → Wi-Fi connection, find the created network, and enter the password. A successful connection will be confirmed by the appearance of the Wi-Fi icon in the upper corner of the screen. webOS.

How to share Wi-Fi from an iPhone (iOS) to a TV
Equipment owners Apple use the "Tethering" feature, which is deeply integrated into the system. To connect your LG TV to the internet via an iPhone, you need to go to Settings → Cellular → Personal Hotspot and enable the "Allow Others" switch. Make sure the "Maximum Compatibility" option is enabled if your TV is older and doesn't see the 5 GHz network.
The Apple ecosystem offers a unique instant connection feature. If your LG TV supports AirPlay 2 If both devices are on the same network (or your phone is broadcasting the network the TV is connected to), you can stream content without entering a password. However, for full internet access to the TV via your iPhone, you will still need to pair it initially using the Wi-Fi menu on the remote.
⚠️ Please note: Carriers may block or impose additional charges for tethering on iOS devices. Check your plan's terms to avoid unexpected charges.
Interface webOS LG TVs work great with iOS, but DNS conflicts can occur when sharing the internet. If websites don't load on your TV even though you have a connection, try manually entering the DNS in your TV's network settings, for example, using Google's (8.8.8.8) or Cloudflare (1.1.1.1). This often solves problems accessing streaming services.
Using DLNA and the LG TV Plus app
If your goal isn't just to give your TV internet access, but to show specific photos or videos stored on your phone, hotspot mode may be overkill. In this case, it's more efficient to use Wi-Fi technology. DLNA or a branded application LG TV PlusBoth devices must be connected to the same local network (even if the phone is distributing this network).
Application LG TV Plus (or its new analogue LG ThinQ) allows you to control content directly. After installing the app on your smartphone and connecting to your phone's Wi-Fi network, launch it and select your TV from the list of available devices. You can stream videos from your gallery, music, and even mirror your screen.
Advanced users can transfer files using the built-in file manager. Enable the "Nearby" or "Nearby Share" feature on your phone, find the TV in the list of devices, and send the file. A notification will appear on the TV screen informing you of the transfer request, which you must confirm with the remote.
| Method of transmission | Required software | Transfer speed | Format support |
|---|---|---|---|
| Access point (Hotspot) | Standard settings | Depends on 4G/5G | Any (streaming) |
| DLNA / Smart Share | Gallery / Video | High (locally) | MKV, MP4, JPEG |
| LG ThinQ App | LG app | Average | Multimedia |
| Screen Share (Miracast) | Screencasting | High | Full screen |
Troubleshooting connection and stability issues
A common problem is when the TV detects the network but fails to connect, displaying the error "Unable to connect to the network." First, try changing the access point name on your phone, removing special characters or Cyrillic characters. Some Wi-Fi modules in LG TVs are sensitive to SSID encoding.
The second common scenario is an IP address conflict. If your phone was previously sharing the network with the same settings, but your TV has "remembered" the old settings, you may need to reset your network settings. On an LG TV, this is done via Settings → All settings → General → Network → Reset Wi-Fi settings.
Hidden DNS settings
If the Internet on your TV is slow, try disabling automatic DNS configuration in the advanced Wi-Fi settings on your TV and entering static addresses: 8.8.8.8 (primary) and 8.8.4.4 (alternative).
It's also worth checking that "Data Saver" mode isn't enabled on your phone. This feature can block background connections necessary for the stable operation of smart TV services, such as weather widgets or app updates.
Optimizing video quality on a mobile connection
Mobile internet is unstable, and for a comfortable movie viewing experience, it's important to set the playback quality correctly. In aggregator apps (Kinopoisk, YouTube, Netflix), manually select the quality. 1080p or even 720pIf the packet drop rate is high, automatic mode often tries to squeeze out the maximum, causing buffering.
The phone's location also plays a critical role. A smartphone's antenna is not the base station's antenna. Place the phone in an open area, away from microwaves, Bluetooth headsets, and other sources of interference. Metal surfaces near the phone can shield the signal, reducing the connection speed.
If you're using a VPN on your phone for sharing, make sure it supports port forwarding or has a dedicated modem mode. Otherwise, the TV will only be able to access local resources, not the global network.
Alternative ways to broadcast content
If traditional Wi-Fi distribution doesn't produce the desired results, consider wired methods or specialized adapters. Using an adapter USB to Ethernet For a phone (if it supports OTG), this will allow you to connect the cable directly to the router, and the phone will distribute this stable signal further, bypassing the loss of the wireless interface.
Another option is to use an HDMI cable with the appropriate adapter for your smartphone (Lightning to HDMI or USB-C to HDMI). This completely eliminates the dependence on Wi-Fi module speed and wireless signal quality, transmitting the image digitally without compression.
Keep in mind that modern LG TVs support multiple protocols. Experiment with combinations: for example, sharing the internet via a USB cable (USB Tethering) often works more reliably and charges your phone simultaneously, although it requires the TV to support USB network adapter drivers.
Why can't my LG TV see my phone's hotspot?
Most often, the problem lies in the frequency range. If your phone only broadcasts at 5 GHz and your TV's Wi-Fi module is old (only 2.4 GHz), they won't "see" each other. Try forcing 2.4 GHz mode or compatibility mode into your smartphone's hotspot settings.
Is it possible to watch online cinemas via streaming from a phone?
Yes, you can. However, data consumption will be high. One hour of HD viewing can consume 1.5 to 3 GB of data. Keep a close eye on your remaining data plan in your carrier's app.
How to reduce traffic consumption when watching movies?
You can always select video quality in the app settings on your TV (YouTube, Okko, IVI). Reducing the quality from 1080p to 720p reduces data usage by almost half, which is critical when using mobile internet.
