However, the standard configuration, which includes an IR remote control, doesn't always provide comfortable navigation of complex menus, especially when entering passwords or searching for content.
Using your smartphone as a remote control or hotspot can solve many navigation and connection stability issues. Wireless connection Access hidden features of the Android TV operating system, which powers many models, via a mobile device. In this guide, we'll walk you through every setup step, eliminating common user errors.
Before setting up, make sure your hardware supports Wi-Fi networks. Some budget models require an external USB adapter, while high-end versions have a built-in module. Understanding your set-top box's hardware capabilities Lumax will be the first step towards successful integration into your home network.
Checking compatibility and preparing equipment
The first step in any technical setup is an audit of the existing equipment. Not all set-top box models Lumax have a built-in Wi-Fi module, so it's important to know the exact specifications of your device. If the specifications indicate support for standards 802.11 b/g/n, then the built-in module is present. Otherwise, you'll need to purchase a compatible USB Wi-Fi adapter, a list of which is usually available on the manufacturer's official website.
Your smartphone must also meet certain requirements. For effective control via the app, the operating system must be at least Android 5.0 or iOS 11Older versions may not support the required discovery protocols, making it impossible to find the set-top box on the local network. Ensure both devices are within range of the router's signal.
⚠️ Attention: Menu interfaces and item names may vary slightly depending on the firmware version. If you don't find an exact match, look for synonyms or similar sections in the system settings.
The stability of the entire system directly depends on the signal quality. If the router is located far from the TV, using a smartphone as a bridge or remote control may experience delays. In such cases, it is preferable to use Ethernet cable for initial setup, and then switch to wireless control.
Using your smartphone as a remote control
The most common use case for the phone is replacing a lost or inconvenient IR remote control. This is done using Wi-Fi Direct technology or a local network connection. You'll need to install a specialized app, such as Android TV Remote Control from Google or a proprietary solution Lumax Remote, if it is available for your model.
The pairing process begins with launching the app on your smartphone after both devices are connected to the same network. The app will automatically scan the network segment and present a list of available devices. A connection confirmation prompt may appear on the TV screen, along with a code that must be entered on the smartphone screen to establish a secure connection.
- 📱 Download the official TV control app from the Google Play or App Store.
- 📶 Make sure your phone and set-top box Lumax connected to the same router.
- 🔢 Enter the pairing code displayed on the TV screen into the app.
- ✅ Allow access to the microphone to use voice search.
The advantage of this method is the ability to quickly enter text. A smartphone's virtual keyboard is much more convenient than navigating with the remote's arrow keys when searching for videos on YouTube or entering a Wi-Fi login. Furthermore, many apps allow you to stream photos and videos from your phone's gallery directly to your TV screen via the protocol. DLNA or Cast.
Setting up Wi-Fi via the set-top box menu
If you want to configure the set-top box itself for internet access, using your phone only as a password source or access point, the procedure is different. You need to go to the main system menu and find the settings section. This is usually marked with a gear icon or located in the upper right corner of the interface.
In the menu that opens, select the item Network and Internet or Wireless & NetworksA list of available wireless networks will appear. Find your router's name (SSID) in the list and click on it. If the network is hidden, select the option to add the network manually and enter the name, down to the last character.
At the password entry stage, using the connected smartphone remote control becomes critical. The virtual keyboard helps prevent errors when entering complex characters. After entering the security key, the system will attempt to establish a connection. A successful connection is confirmed by the appearance of the Wi-Fi icon in the status bar and the updating of widgets.

| Gateway | Router address | 192.168.0.1 or 1.1 |
| DNS | Name servers | Automatically or 8.8.8.8 |
⚠️ Attention: When setting up a static IP address, make sure that the selected address is not already occupied by another device on the network, otherwise an address conflict will occur and the Internet will not work.
Hotspot mode on a smartphone
When your home router is unavailable or unstable, you can use your smartphone as an internet source. This method is called tethering. You need to enable modem mode in your mobile device's settings. Please note that this will use your mobile carrier's data plan, so be sure to check your data plan.

The network name will match your smartphone's name or the name you specified in the hotspot settings. Enter the password you set for the access point and wait for the connection to complete. The connection speed will depend on the quality of your cellular signal (3G/4G/5G).
Settings → Network & Internet → Hotspot & tethering → Wi-Fi hotspotUsing your phone as a router can be useful for initial setup or firmware updates if your wired internet is temporarily down. However, this method is not recommended for regular viewing of heavy 4K content due to potential instability and data limits.
Why doesn't the set-top box see the phone's access point?
Some older Lumax set-top boxes don't support the 5 GHz frequency, which modern smartphones can use in hotspot mode. Try forcing the phone's hotspot settings to use the 2.4 GHz band.
Solving common connection problems
Even if you strictly follow the instructions, technical difficulties may arise. One of the most common issues is an incorrect date and time. If the system time is incorrect, security certificates fail verification, and connecting to secure Wi-Fi networks becomes impossible. Check that the date in the menu is correct. Settings → Date and Time.
Another common cause is an overflowing network service cache. If your set-top box has forgotten the network or is constantly losing connection, try resetting your network settings. This will restore your network settings to factory defaults without affecting your personal files or installed apps.

Firmware update and performance optimization
To ensure stable operation of Smart TV functions and proper interaction with your smartphone, it's important to keep the software up to date.
