Modern DEXP TVs, a popular budget option on the Russian market, often run the Android operating system, which provides access to a huge number of apps and services. However, to take full advantage of the features Smart TV, you first need to ensure a stable internet connection. Despite the presence of a LAN port, most users prefer a wireless connection, which eliminates unnecessary wires and allows the device to be placed anywhere in the room.
Activating a wireless module may seem trivial, but in practice, owners often encounter subtle obstacles, such as frequency band incompatibilities or firmware glitches. In this article, we'll detail the steps for various interface versions, examine specific router settings that can block the connection, and offer effective diagnostic methods if standard solutions fail.
It's important to understand that the menu interface may vary slightly depending on the TV model and operating system version, but the operating logic remains the same. We'll cover both standard paths through the system settings and alternative methods, including using USB adapters for models with a faulty or missing built-in module.
Initial equipment check and preparation
Before delving into software settings, you need to ensure the physical components are working properly and the external infrastructure is ready. Often, the problem lies not with the TV, but with the router configuration or simply a lack of signal in the reception area. Make sure your router is working properly, its indicators are lit, and the internet connection is active and not blocked by your ISP.
It's also worth paying attention to the placement of the equipment. If the DEXP TV is located in a recess, behind furniture, or significantly away from the access point, the signal strength may be critically low for stable operation of multimedia applications. In such cases, even with a successful network connection, video content will stutter or buffer.
- 📡 Check the indicators on your router: a flashing WLAN or antenna icon indicates data transfer.
- 🔌 Make sure the TV is connected to the power supply and the remote control responds to commands.
- 📱 Test Wi-Fi on another device (smartphone or tablet) in the same room.
- 🔋 If you are using a voice-controlled remote control, please check its battery level as this may affect the menu response speed.
⚠️ Attention: Some DEXP models are equipped with separate antennas for digital terrestrial television (DVB-T2) and the Wi-Fi module. Be careful not to mix up the inputs; connecting an external antenna to the Wi-Fi port can damage the tuner unit.
For proper wireless connection operation in a strong reception area, the signal strength must be at least -70 dBm. If the signal strength is lower, we recommend relocating the router or using a Wi-Fi repeater to boost the signal.
Setting up Wi-Fi via the standard Android TV menu
Most modern DEXP models run the Android TV operating system or its variants. The settings interface on these devices is standardized, making it easy to find the necessary settings. To begin the connection process, you'll need to press the button. Settings (gear) on the remote control or go to the settings menu through the main screen.
In the menu that opens, you need to find the section responsible for network connections. Depending on the firmware version, it may be called Network and Internet, Network or simply Wi-FiAfter entering this section, the system will automatically scan for available wireless networks within range of the TV's antenna.
Select the name of your home network from the list. Please note that the network name (SSID) must match the one on the router's label or the one you previously set. If the network is hidden, you will need to select "Add network" and enter the name manually. Once selected, enter the password using the on-screen keyboard and click "Connect."

If authorization is successful, the "Connected" status will appear next to the network name, and a Wi-Fi icon will appear in the status bar (usually in the upper right corner). The TV is now connected to the global network and ready to install apps or launch online movie theaters.
Troubleshooting network visibility and connectivity issues
A DEXP TV failing to detect or connect to a Wi-Fi network is a common issue. This is often due to frequency band incompatibility. Many routers broadcast in the 5 GHz band, while budget TV models may only support the 2.4 GHz standard. In this case, the 5 GHz network simply won't appear in the list of available networks.
Another possible cause could be the security or encryption type set on the router. If the router is configured to use older protocols (WEP) or, conversely, newer ones that aren't supported by the TV module, the connection will fail. It's also worth checking whether MAC address filtering is enabled on the router, which blocks unknown devices.
| Problem | Probable cause | Solution method |
|---|---|---|
| Network not found | 5 GHz band | Enable 2.4 GHz on your router |
| Authentication error | Incorrect password | Double-check your password, letter case |
| Obtaining IP address... | DHCP error | Reboot the router and TV |
| Weak signal | Obstacles/Distance | Use a repeater or extender |
⚠️ Attention: If your router broadcasts a network with the same name (SSID) for both 2.4 and 5 GHz frequencies, try temporarily separating them by assigning different names (for example, Home_24 and Home_5) so that the TV connects to the correct range.
To diagnose the issue, you can try connecting to the access point on your smartphone. If the TV detects and connects to the phone, then the Wi-Fi module is working properly, and the problem lies in the router settings or standard compatibility.
Why does the TV only see 2.4 GHz?
Many budget Wi-Fi modules in DEXP TVs are single-band and support only the 802.11n (2.4 GHz) standard. They are physically unable to "see" networks operating exclusively in the 5 GHz band (802.11ac/ax), as the radio signal frequencies are fundamentally different.
Using external USB Wi-Fi adapters
In some cases, the built-in module may fail, or it may not be included in a particular TV model. The solution is to use an external USB Wi-Fi adapter. However, not every adapter will work with the TV, as the drivers must be built into the device's operating system.
DEXP, like many other brands, uses chipsets from MediaTek, Realtek, or Ralink. Therefore, when purchasing an adapter, it's important to choose models that are advertised as Android TV compatible and labeled accordingly. Adapters with RT5370, MT7601, or similar chipsets are most commonly compatible, but the list of supported devices may change with firmware updates.
The installation process is simple: plug the adapter into your TV's USB port (preferably a 2.0 port or a dedicated Wi-Fi port, if available). A new interface should appear in the network settings menu or the network search should be activated. If the adapter isn't detected, your TV may need a firmware update.
- 💾 Make sure that the adapter's file system (if it has internal memory) does not conflict with the system, although this is rare for network cards.
- 🔌 Avoid using long USB extension cables, as this may cause voltage drop and unstable operation of the module.
- 🔄 After connecting the adapter, you may need to restart the TV to initialize the drivers.
Using an external adapter is a great way to extend the life of your TV if a built-in component burns out, for example, after a thunderstorm or power surge, provided that the Android TV itself is functioning correctly.
Reset network settings and update software
If a software glitch has caused the Wi-Fi slider to become grayed out or unresponsive, resetting the network settings is an effective solution. This will reset your connection settings to factory defaults, deleting saved passwords and IP address configurations, but will not affect your personal data or installed apps.
To perform a reset, go to Settings → Net (or Additionally) and find the item Reset network settings or Forget the network for all connections. In more complex cases, a full factory reset may be required (Factory Reset), but this is an extreme measure and requires reconfiguring all applications.
Often, the cause of module failure is an outdated firmware version containing driver errors. Check for updates in the section About TV → System updateIf the automatic search doesn't find updates via Wi-Fi, you can download the firmware file from the official website, transfer it to a USB drive, and update the TV manually.
⚠️ Attention: It is strictly recommended not to interrupt the power supply during the software update process. A power surge or power outage during the firmware update can cause irreversible software damage (bricked device), which can only be repaired at a service center.
Regular software updates ensure not only the stability of the Wi-Fi module, but also the security of your data by patching vulnerabilities in the Android operating system.
