How to stream movies from your phone to your TV via a Wi-Fi router: all the working methods

Have you downloaded a movie to your phone but want to watch it on your big TV screen—without the hassle of wires and adapters? Stream content via your home TV. Wi-Fi router This task is solved in minutes. The main advantage of this approach is that it requires no additional equipment: a stable local network connection and compatible devices are sufficient.

In this article, we will look at all the current methods of broadcasting video from Android or iPhone on Smart TV (or a regular TV with a set-top box) via a router. From standard protocols like DLNA to proprietary technologies Samsung Smart View, LG Screen Share And Google CastYou'll also learn how to overcome common issues, such as video lagging or audio delays.

Spoiler alert: most modern TVs and smartphones will be able to handle the built-in features without the need for any third-party apps. However, if your device was manufactured before 2018, you may need to update the firmware or use alternative solutions. Let's take things in order.

1. Preparation: What to check before submitting a video

Before setting up a broadcast, make sure your network and devices meet the minimum requirements. Otherwise, you risk experiencing lag, connection drops, or a complete loss of signal.

Here mandatory conditions For stable video transmission via a router:

• 📶 One Wi-Fi router - the phone and TV must be connected to the same network (It doesn't matter whether it's via cable or over the air.) If the TV uses Ethernet and the smartphone uses Wi-Fi, that's acceptable, as long as both devices are on the same subnet.
• 📱 Compatible devices — the TV must support at least one of the protocols: DLNA, Miracast, AirPlay (For Apple) or Google CastCheck the availability of functions on your smartphone. Smart View (Samsung), Screen Mirroring (Xiaomi) or Wireless Display (Android).
• 🔄 Current firmware — Outdated software may not support new transmission standards. Update your TV using the menu. Settings → Support → Software Update and smartphone in the section Settings → System → System Update.
• 📊 Sufficient network speed — for broadcast Full HD (1080p) requires at least 10 Mbps, For 4K — from 25 MbpsCheck the speed on the website Speedtest.net (from phone and TV, if there is a browser).

If your TV was released before 2016 and does not support Wi-Fi Direct or Miracast, may be needed media player (For example, Xiaomi Mi Box or Amazon Fire Stick) or DLNA server on the router (if the model supports it, as ASUS RT-AX88U or TP-Link Archer C5400).

⚠️ Attention: Some routers (especially budget models from Tenda or Mercusys) can block multicast traffic needed for DLNAIf the video is not transmitted, check your settings. IGMP Snooping in the router admin panel (usually in the section LAN → Multicast).

2. Method 1: DLNA is a universal protocol for any device

DLNA (Digital Living Network Alliance) is the most widespread standard for transferring media files over a local network. It works on most TVs (since 2012) and smartphones without requiring additional software.

How it works: Your phone acts as a DLNA servers, and the TV is client, which fetches the file on request. The advantage of this method is minimal load on the smartphone's processor (unlike screen mirroring). The disadvantage is that not all video formats are supported (for example, .mkv With DTS- sound may not be reproduced).

Instructions for Android:

1. Open Gallery or File manager (For example, Files by Google).
2. Select a video, click "Share" (or "Send»).
3. Find the item in the list of options DLNA, Transmit to TV or similar (the name depends on the firmware).
4. Select your TV from the list of available devices.

Instructions for iPhone/iPad:

• 🍎 Install the application DLNA server (For example, 8player Lite or TV Assist).
• 📁 Upload the video to the app or grant access to your Photos folder.
• 🔍 Click on the file and select your TV from the list Renderers.

If your TV does not appear in the list, check:

• 🔌 Are both devices connected to the same Wi-Fi network (not a guest network!).
• 🔄 Is it enabled? DLNA on TV (usually in the menu Network → DLNA Settings).
• 🛡️ Does your router's firewall block multicast traffic (see warning above).

⚠️ Attention: If the video is slow when playing through DLNA, try reducing the file bitrate (for example, using an application HandBrake on PC) or recode it into .mp4 with codec H.264.

3. Method 2: Miracast and Screen Mirroring

If DLNA is not suitable (for example, you need to broadcast not a file, but the entire smartphone screen), use Miracast — wireless display mirroring technology. It works on most Android-devices (starting with version 4.2) and TVs with Wi-Fi Direct.

Advantages of the method:

• 🎮 Transmitted full screen — you can show not only videos, but also games, presentations, or social networks.
• 🔄 Minimal latency (around 50–100 ms) – suitable for watching movies.
• 🔌 Doesn't require internet - a direct connection between your phone and TV is enough.

Flaws:

• 🔋 High battery consumption - Mirroring puts a strain on the smartphone's processor.
• 📶 Possible lag when the Wi-Fi signal is weak.
• 🍎 Doesn't work on iPhone (For Apple there is an alternative - AirPlay).

How to enable Miracast on Android:

1. Open Settings phone.
2. Go to the section Connections → Screen Mirroring (or Smart View, Wireless Display, Transmit to TV — the name depends on the model).
