A situation where your landline provider is down or your Wi-Fi router suddenly fails can catch you off guard, especially if you were planning a movie night. In such cases, the "Save" feature comes to the rescue. mobile hotspot, turning your smartphone into a fully-fledged router. For owners of TVs of the brand DEXP, which often run on Android TV or their own shells, this method is one of the fastest ways to regain access to online content.
However, despite its apparent simplicity, the process of pairing mobile internet with a large screen has its own technical nuances. It's important to understand the difference between simply distributing traffic to YouTube and setting up a local network for multimedia transmission. In this article, we'll cover all aspects of setup in detail, from basic connection to advanced methods of streaming content via DLNA server.
Using your smartphone as a modem isn't just a temporary solution, but also a powerful tool for diagnosing network issues on your TV. If your DEXP If your TV stops detecting your home network, testing it with a mobile hotspot can help you determine whether the problem lies with the router or the TV itself. Let's look at how to properly configure this process to avoid unnecessary data usage and ensure a stable connection.
Preparing your smartphone and checking your tariff plan
Before you start setting up your TV, you need to make sure your smartphone is ready to work as a modem. Modern devices based on Android And iOS They have built-in network creation tools, but their operation is directly dependent on the mobile operator's settings. The first step should always be checking your remaining data allowance, as high-definition video content consumes data very quickly.
Pay attention to your data plan type. Many mobile operators separate data traffic into "phone" and "data sharing," or limit speeds when connecting external devices. If you notice that your internet speed drops to a crawl after connecting your TV, your provider may be limiting your data. In this case, consider the "Unlimited Internet" option or a special modem package.
- 📱 Make sure that mobile data (3G/4G/5G) is enabled on your smartphone.
- 💰 Check your balance and remaining gigabytes through your operator's app.
- 🔋 Charge your phone's battery to 50% or connect it to a charger.
- 📶 Make sure there is a strong cellular network signal where the TV is installed.
It's also important to consider the technical condition of the smartphone itself. Hotspot mode puts significant strain on the processor and radio module, resulting in intense heat generation. If you plan to watch a movie longer than two hours, it's best to keep the phone connected to a charger and, if possible, remove the protective case to improve heat dissipation. Failure to do so may result in the Wi-Fi security system automatically disabling the module.
⚠️ Please note: Some tariff plans from the Big Four carriers automatically detect data tethering and may block it or require a separate payment. Before using it, check the terms of your plan in your personal account to avoid any unpleasant surprises with your balance.
Setting up a hotspot on Android and iOS
The process of activating the tethering mode varies depending on your smartphone's operating system. On devices Android The interface may differ slightly depending on the manufacturer (Samsung, Xiaomi, Pixel), but the steps remain the same. Find the section responsible for network connections and activate the personal hotspot feature.
For iPhone owners (iOS) lucked out with a somewhat more unified interface. Here, the setting is located in the cellular menu. Setting a password is crucial. By default, the system may offer a weak key or not ask for one at all, allowing neighbors to connect to your network and waste your data. Always use a secure protocol. WPA2/WPA3.
Particular attention should be paid to the frequency range. Modern smartphones allow you to choose between 2.4 GHz and 5 GHz. TVs DEXP Older models may not support the 5 GHz frequency, so if your device isn't detecting the network, try forcing your smartphone to switch to 2.4 GHz mode. This will improve compatibility, although it will slightly reduce the maximum data transfer speed.
Path for Android: Settings → Connections → Mobile hotspot and tethering → Mobile hotspotPath for iOS: Settings → Cellular → Personal Hotspot → Allow Others to UseOnce the feature is activated, the network name (SSID) and password will appear on your smartphone's screen. Write this information down or keep the screen on, as you'll need it to enter it on the TV. Avoid changing the network name to something too exotic or containing special characters, as some firmware versions may not support this. DEXP may not display such names correctly in the list of available networks.
Connecting the DEXP TV to the created network
Once your smartphone has started broadcasting a Wi-Fi signal, you need to go to the TV's settings. TV interface DEXP It may be based on different versions of Android TV or proprietary systems, but the network search algorithm is standard. You need to go to the network settings menu and start searching for available connections.
In the list of detected networks, find the name (SSID) you set on your smartphone. When you select a network, the TV will ask for a password. Be careful when entering it: use the on-screen keyboard and carefully check the capitalization, as even a single character error will result in connection failure. The system will display an authentication error message if the password is entered incorrectly.

Local Area Networking and Media Streaming (DLNA)
Sharing the internet isn't the only opportunity offered by connecting a smartphone and TV. A much more interesting scenario is creating a local network for file transfer. If you have photos or videos on your phone that you want to show on the big screen without cables, this technology can help. DLNA or built-in broadcast functions.
To implement this scenario, you don't even need an active mobile internet connection. The main thing is that both devices are on the same local network created by your smartphone. Turn on the hotspot and connect your TV to it, but you don't even need to use any data. Next, open a gallery app or video player on your smartphone that supports the "Broadcast" or "Cast" feature.
Your TV should appear in the list of available devices for streaming. DEXPWhen you select a device, the image or video will be transmitted directly. This method is ideal for sharing family archives or watching downloaded movies that don't require internet streaming. Image quality in this case depends on the smartphone's processor power and Wi-Fi speed.
⚠️ Please note: When streaming heavy video (4K HDR) via DLNA from your phone to your TV via Wi-Fi, stuttering may occur if the signal is unstable. For a comfortable viewing experience, we recommend using files with a bitrate no higher than 15-20 Mbps or lowering the resolution in your player settings.
Why doesn't the TV see the phone in DLNA?
Often, the problem lies in firewall settings or app permissions. Make sure the player app on your smartphone has permission to access the local network. Also, check that both devices are connected to the same access point (SSID), and not one to your mobile data plan and the other to your home router.
Compatibility chart and common problems
Despite standardized technologies, users may encounter various issues when pairing devices of different generations. Below is a table to help identify typical symptoms and troubleshooting methods. Understanding the nature of the error can reduce the time it takes to find a solution.
| Symptom | Probable cause | Solution method |
|---|---|---|
| The TV doesn't see the phone's network. | Frequency incompatibility (5 GHz vs. 2.4 GHz) | Switch your smartphone's hotspot to 2.4 GHz mode |
| Authentication error | Incorrect password or encryption type | Check the password and change the security type to WPA2-Personal. |

The problem with DNS servers deserves special attention. Sometimes the TV DEXP The TV connects to the access point, but apps don't load content. Manually entering DNS addresses in the TV's network settings helps in this case. Try setting up Google's DNS (8.8.8.8) or Cloudflare (1.1.1.1), which often solves problems with access to update servers or streaming services.
It's also worth mentioning the number of connected devices. A smartphone, acting as a router, has a limited number of simultaneous connections and overall bandwidth. If a tablet, laptop, and TV are all connected to your hotspot at the same time, the speed on each device will drop, which could make watching videos impossible.
Traffic optimization and security
Using mobile internet on a big screen can quickly deplete your data plan. TVs DEXP Smart features can automatically launch app updates, sync data, or download high-quality previews immediately after connecting to the network. To control this process, you need to set up restrictions.
In your TV's settings, find the "Data Usage" or "Data Saver" section. Here you can set limits or disable automatic app updates over your mobile network. It's also recommended to manually set playback quality in YouTube and other video service settings, such as limiting it. 720p or 1080p, instead of automatic selection, which may try to enable 4K.
- 🛑 Disable automatic app updates in the Google Play Store on your TV.
- 📉 Set a video quality limit in the YouTube settings on your TV.
- 🔒 Use a strong Wi-Fi password to prevent your neighbors from connecting to your network.
- 👁️ Monitor the traffic indicator on your smartphone in real time.
Security is also critical. When you share Wi-Fi, your phone becomes visible to other devices. While encryption protects transmitted data, you shouldn't use these networks to enter sensitive banking information on your TV. After you finish watching, be sure to disable the hotspot on your smartphone to avoid leaving a security hole and wasting battery.
⚠️ Please note: DEXP TV menu interfaces may vary depending on the specific model and software version. If you cannot find the described options, please refer to the official documentation for your model or visit the manufacturer's website for the most up-to-date instructions, as firmware updates are regularly available.
Questions and Answers (FAQ)
Is it possible to share Wi-Fi from a phone to a DEXP TV without mobile internet?
Yes, this is possible for local file transfers. If you enable hotspot on your phone (even without an active SIM card or data plan), the phone will create a local network. By connecting a TV to this network, you can stream photos and videos via DLNA, but access to online services (YouTube, Netflix) will not work.
Why does my DEXP TV see the network, but it says "Limited" or "No Internet Access"?
Most likely, your smartphone doesn't have mobile data enabled (4G/LTE icon) or has run out of data. Also, check if there's a limit on the number of connected devices in your phone's hotspot settings.
Does Wi-Fi sharing affect the speed of mobile internet on the phone itself?
