Connecting a Second TV to the Internet via a Rostelecom Wi-Fi Router: 3 Proven Methods

Connecting a second TV to your home Wi-Fi network via a router Rostelecom — a challenge many users face when expanding their home multimedia infrastructure. Unlike the first device, where setup is often performed by a technician during installation, adding a second TV requires independent efforts. The main difficulties arise due to differences in TV interfaces across brands and router firmware. Sagemcom, Sercomm or Huawei, as well as provider restrictions.

In this article, we will look at three working connection methods (wireless, via WPS and via cable), which are relevant for modern Smart TV on platforms Android TV, webOS, Tizen And Google TVWe'll be focusing on common errors, from missing IP addresses to DHCP issues, as well as network optimization for stable video streaming. 4K on two devices simultaneously. If your router is giving out Rostelecom, but has non-standard firmware (for example, after an upgrade to Wi-Fi 6), at the end of the article you will find universal solutions.

1. Preparation: What to check before connecting a second TV

Before you begin setup, make sure your network is ready for the new device. Key parameters that affect a successful connection include:

• 📶 Wi-Fi signal strength: The second TV shouldn't be in the "dead zone." You can check the signal strength using the app. Wi-Fi Analyzer (Android) or in the router's web interface (192.168.1.1) in the section Wireless Network → Statistics.
• 🔄 Number of connected devices: routers Rostelecom basic configuration (for example, Sagemcom F@st 2804) limit the number of simultaneously connected gadgets to 10–15If the limit is reached, turn off unnecessary devices.
• 🔒 Encryption type: TVs older than 2018 may not support WPA3In your router settings, temporarily switch to WPA2-PSK (AES).
• 📡 Wi-Fi channel and frequency: for stable operation Smart TV It is recommended to use a range 5 GHz (if the TV supports it) or channels 1, 6, 11 in the range 2.4 GHz (they are less susceptible to interference).

If your router was issued Rostelecom until 2022, it may have the function activated Band Steering (automatic switching between 2.4 And 5 GHz). This option may cause problems connecting older TVs. You can disable it in the section Wi-Fi Settings → Advanced.

⚠️ Attention: If your tariff Rostelecom limits internet speed when more than one is connected Smart TV (Applies to the Basic and Standard packages), check the terms in your personal account. Some plans require the "Multi-screen" option for simultaneous streaming on multiple devices.

2. Method 1: Connecting via Wi-Fi (universal method)

This is the most common option, suitable for 90% of modern TVs. The instructions are valid for the following models: Samsung (series QLED, Crystal UHD), LG (OLED, NanoCell), Sony Bravia, Xiaomi Mi TV and others. The main requirement is the presence of a Wi-Fi module in the TV.

Step 1: Activate Wi-Fi on your TV

• 📺 Press the button on the remote control Home (or Smart), then go to Settings → Network → Network settings.
• 🔍 Select an item Wireless network (Wi-Fi) and turn on the search for available networks.
• 🔗 Find your network name (SSID) in the list. If it's not there, check if the network is hidden in your router settings (Hide SSID should be disabled).

Step 2: Enter your password and configure settings

• 🔐 Enter your Wi-Fi password (it's on the router sticker or in the contract) Rostelecom). If you have changed the password but forgotten it, you can view it in the router's web interface by following the path Wireless Network → Security.
• 🔄 After connecting, the TV may request a firmware update. Decline the update at this stage - check the stability of the connection first. Updating over an unstable Wi-Fi connection may result in a failure.
• 📋 If the TV asks IP address, Gateway or DNS, select Obtain automatically (DHCP)Manually entering parameters is only necessary if the network has specific settings.

If your TV does not connect, check:

• 🔌 Has the router been rebooted (turn off the power for 30 seconds).
• 🔄 Is it turned on on the router? MAC address filter (turns off in Security Settings → MAC Filtering).
• 📡 Does the Wi-Fi channel conflict with neighboring networks (use the app Wi-Fi Analyzer for analysis).

3. Method 2: Connecting via WPS (fast and secure)

Technology WPS (Wi-Fi Protected Setup) allows you to connect your TV to your router without entering a password—just press a button on the router. This method is suitable for devices that support WPS (most models since 2016). The advantage is the minimal risk of entering a password incorrectly.

Step 1: Check WPS support

• 📺 On your TV, go to Settings → Network → Wi-Fi → Additional settings.
• 🔍 Find the item WPS (PBC) or Connection by buttonIf it is not there, your TV does not support WPS.

Step 2: Activate WPS on your router

• 🔘 Press the physical button WPS on the router body (usually labeled or marked with a 🔄 icon). Hold it for 2–3 seconds until the indicator light starts flashing.
• ⏱️ Do you have 2 minutesto terminate the connection. If the connection time expires, press again.
• 📺 On your TV, select Connect via WPS and wait for the process to complete (usually takes 10-30 seconds).

⚠️ Attention: Some routers Rostelecom (For example, Sercomm RV6699) have the WPS function disabled by default. To activate it, go to the router's web interface (192.168.1.1), go to Wireless Network → WPS and turn on the option Allow connection via PBC.

What to do if WPS doesn't work?

If the TV does not connect after pressing the WPS button on the router, check:

- Does your router support the WPS standard (older models may only have a PIN method).

- Is the antivirus or firewall on the router blocking the new connection?

- Is the "Guest Network" mode enabled? WPS is usually disabled in it.

4. Method 3: Connecting via cable (for maximum stability)

If your TV is located near the router or a network cable is laid, connecting via Ethernet guarantees minimal delays and maximum speed - critical for 4K HDR-content or online games. This method also solves problems with a weak Wi-Fi signal.

Step 1. Physical connection

• 🔌 Connect the TV and router with a cable LAN (usually comes with the router). Use the port LAN1–LAN4 on the router and the connector Ethernet on TV.
• 🔄 If the cable is longer 5 meters, make sure it's categorized Cat 5e or higher (marking is indicated on the shell).

Step 2: Setting up the network on your TV

• 📺 Go to Settings → Network → Network setup → Cable connection.
• 🔄 Choose Obtain an IP automatically (DHCP). If your router is configured to distribute static IP addresses, enter the parameters manually (the data can be found in your personal account). Rostelecom or on the router sticker).

If the Internet does not work after connecting with a cable:

• 🔌 Check if the indicator light is on LAN on the router.
• 🔄 Try a different cable or port on your router.
• 📡 In the router settings (Local Area Network → DHCP) make sure the DHCP server is enabled.

5. Network optimization for two TVs: how to avoid lags

Connecting a second TV may result in speed drops, especially if both devices are simultaneously streaming high-definition video. To avoid lag, adjust the following settings:

• 📶 Lane separation 2.4 GHz And 5 GHz: Assign each TV its own frequency. For example, connect the main TV to 5 GHz (For 4K), and the second one is to 2.4 GHz (For Full HD).
• 🔄 Traffic prioritization (QoS): In the router settings (Additional → QoS) add the MAC addresses of TVs to the list of priority devices.
• 📡 Changing the Wi-Fi channel: If both TVs are connected to 2.4 GHz, select channels with minimal interference (eg 1 And 11).
• 🔌 Disabling background traffic: In your router, limit the speed for devices that use the Internet in the background (for example, smartphones with automatic updates).

For routers Rostelecom with firmware Sagemcom option available Multimedia priority (QoS → Traffic Priorities). Turn it on and select Video and streaming for TV MAC addresses.

6. Common mistakes and their solutions

Even with proper setup, connecting a second TV can still fail. Let's look at the most common issues and how to fix them.

If your TV connects to the network but won't open apps (e.g. YouTube or Netflix), the problem may be in DNSTry manually entering alternative DNS servers:

• 8.8.8.8 (Google DNS)
• 1.1.1.1 (Cloudflare DNS)
• 77.88.8.8 (Yandex DNS)

To do this, go to the TV network settings, select Advanced → DNS and enter one of the addresses.

⚠️ Attention: If the first TV starts to slow down after connecting a second TV, check the load on the router. Some models (for example, Sagemcom F@st 1744) cannot handle the simultaneous processing of two 4K-streams. The solution is to update the router firmware or install a more powerful model (for example, Keenetic or ASUS RT-AX55).

7. Speed ​​check and connection testing

After successfully connecting the second TV, you need to ensure that the internet speed is sufficient for comfortable viewing. You can check this directly on the TV or through the router.

Methods to check speed:

• 🖥️ Via a router: Go to the web interface (192.168.1.1) and check the speed in the section Status → WAN.
• 📱 Via smartphone: Connect your phone to the same network and run SpeedtestCompare the results with the stated speed according to the tariff Rostelecom.

Minimum speed requirements for different content types:

• SD (480p): 3 Mbps
• HD (720p–1080p): 5–10 Mbps
• 4K (2160p): 20–25 Mbps
• 4K HDR + Dolby Atmos: 35+ Mbps

If the actual speed is lower by 30% and more, contact support Rostelecom (telephone 8 800 100 08 00) or check:

• 🔌 Is the router overloaded (number of connected devices).
• 📡 Is there any interference from neighboring networks (use channels 1, 6, 11 V 2.4 GHz).
• 🔄 Is the function activated on the router? Bandwidth control (turns off in Additional → QoS).

8. Alternative solutions: if nothing helps

If standard connection methods do not work, consider alternative options:

• 📡 Using a Wi-Fi repeater: The device boosts the signal in remote rooms. Any model with this support will do. Wi-Fi 5 (For example, TP-Link RE605X).
• 🔌 Powerline adaptersInternet is transmitted through electrical wiring. Ideally, the router and TV should be in different rooms but on the same power grid.
• 📶 Mobile Internet (4G/5G): If Rostelecom limits the number of devices, connect a second TV via a USB modem (for example, Huawei E3372).
• 🖥️ DLNA/Miracast: If your TV doesn't have Smart features, stream content from your laptop or smartphone using technology Miracast or through DLNA server (For example, Plex).

For Powerline adapters it is important:

• Use adapters from the same manufacturer (eg. TP-Link AV1000).
• Plug them directly into a wall outlet, without extension cords.
• Avoid connecting through surge protectors, as they block high-frequency signals.
