How to connect a Smart TV to digital television via Wi-Fi: a complete guide

Digital television has long been the standard—it offers better picture quality, more channels, and no interference. But many users Smart TV still don't know how to connect it correctly through Wi-FiTo avoid signal problems or lost channels, we'll cover every step: from selecting equipment to fine-tuning your router and TV.

Let's clarify right away: we are talking about digital terrestrial television (DVB-T2), not about cable or satellite. Wi-Fi connection is only possible with TV tuner with DVB-T2 support (built-in or external) and a properly configured home network. If your TV can't receive over-the-air channels even via cable, the problem may be with the antenna or coverage area, not the Wi-Fi settings.

1. Checking the compatibility of the TV and equipment

Before setting up your connection, make sure that your Smart TV supports digital television reception without additional devices. Most modern models (Samsung QLED 2020+, LG OLED CX/C1, Sony Bravia X90J and newer) have a built-in DVB-T2 tunerBut there are some nuances:

  • 🔍 Budget models (For example, Xiaomi Mi TV 4A or TCL 4-Series) may require external DVB-T2 set-top box even with Smart functions.
  • 📡 Old TVs (before 2018) often lack support HEVC (H.265) — a codec used to compress digital TV in Russia.
  • 🌍 Regional restrictions: some models for the European market (Philips The One) may not support Russian broadcasting standards.

To check for tuner availability:

  1. Enter the TV menu (button Home or Menu on the remote control).
  2. Go to the section Settings → Broadcast → Antenna (path may differ).
  3. If there is an option Digital TV (DVB-T2) — the tuner is built in. Unless Analog TV or Cable (DVB-C) - an external set-top box will be required.
⚠️ Attention: Some TVs (Samsung TU7000 series and below) support DVB-T2 only through cable connection, but not via Wi-Fi relay. In this case, you will have to use HDMI set-top box with internet access.
How do I find out my TV model?

Typically the model is indicated on the sticker on the back of the case (for example, LG 55UN73006LB). You can also go to Settings → Support → TV Info or dial a combination on the remote control Menu → 1 → 1 → 9 → Enter (for Samsung).

2. Equipment required for Wi-Fi connection

To retransmit digital TV via Wi-Fi you will need:

Equipment Purpose Examples of models
DVB-T2 set-top box with Wi-Fi If your TV doesn't have a built-in tuner or HEVC support Xiaomi Mi Box S 2nd Gen, Dune HD Solo 4K, BBK SMP245HDT2
5 GHz Wi-Fi router For stable, stutter-free streaming TP-Link Archer C6, Keenetic Ultra, ASUS RT-AX55
Indoor DVB-T2 antenna To receive an over-the-air signal (if there is no collective) REMO BAS-5310USB, Locus L 041.05, Harper ADVB-2120
HDMI 2.0+ cable To connect the set-top box to the TV (if used) Any certified High Speed cable

If you use external set-top box, it must support:

  • 📶 Wi-Fi 5 (802.11ac) or newer - for artifact-free video transmission.
  • 🔄 DLNA/UPnP or Miracast — for streaming to TV.
  • 📺 HEVC (H.265) — mandatory for Russian DVB-T2.
⚠️ Attention: Cheap consoles without support 5 GHz may slow down when watching channels in Full HDIf your router does not support 5 GHz, consider purchasing Powerline adapter to transmit a signal through electrical wiring.

3. Configuring the router for stable TV signal transmission

Digital TV requires minimal delay And stable channelIf the router is configured incorrectly, the image will appear blocky or freeze. Optimal settings:

  • 📶 Range: 5 GHz (less busy than 2.4 GHz).
  • 🔄 Channel width: 40 MHz (balance between speed and stability).
  • 🔒 Security mode: WPA2-PSK (AES) or WPA3.
  • 📡 Qos (Quality of Service): Enable and set priority for multicast traffic (used for IP-TV).

How to set up using an example Keenetic:

  1. Go to the router's web interface (192.168.1.1).
  2. Go to Wi-Fi → 5 GHz Hotspot.
  3. Install Channel: Auto (5 GHz) or manually select the least loaded one (for example, 36 or 149).
  4. In the section Traffic prioritization (QoS) add a rule for UDP port 1234 (standard for multicast).

For TP-Link:

Advanced → Wireless → Wireless Settings:

- Channel Width: 40 MHz


- Mode: 11ac/n/a (5 GHz)


- Enable WMM: ✔️
⚠️ Attention: If you have dual-band router, give it to the networks 2.4 GHz And 5 GHz different names (For example, MyWiFi_2G And MyWiFi_5G). This will allow the TV to automatically select the optimal range.
