Wirelessly stream media from your computer to your TV via AllShare (now known as Smart View or Screen Mirroring in new models Samsung) is a convenient way to stream movies, photos, and presentations without the hassle of wires. However, many users encounter difficulties setting up this connection: either the router doesn't support the required protocols, the drivers on the PC are outdated, or the TV simply doesn't recognize the computer on the network. In this article, we'll look at All current connection methods via AllShare via Wi-Fi, including alternative methods for old and new TV models, as well as solutions to common errors.

Technology AllShare (or DLNA, on which it is based) allows you to stream content from a PC to a TV over a local network, but requires several key conditions to be met: both devices must be connected to the same Wi-Fi network, and specialized software must be installed on the computer (for example, Samsung PC Share Manager or Windows Media Player (with a DLNA server enabled), and the corresponding mode is activated on the TV. If any link in the chain is configured incorrectly, the connection will fail. Below are step-by-step instructions for different scenarios.

1. Equipment and network requirements

Before you begin setting up, make sure your equipment meets the minimum requirements. AllShare It doesn't work on all devices, or even across models. Samsung There are restrictions:

• 📺 TV: models Samsung 2012–2020 with support AllShare (series D/E/F/H/J/K/M/Q), or new TVs with Smart View or Screen Mirroring. Old Plasma (For example, PS51D8000) may not support Wi-Fi Direct.
• 💻 Computer: Windows 7/8.1/10/11 (for macOS you will need third-party software like AirParrot), with installed Samsung PC Share Manager or an activated DLNA server in Windows Media Player.
• 📶 Router: Wi-Fi standard 802.11n/ac/ax (5 GHz preferred for stability), with support Multicast (enabled by default in most routers, but can be disabled manually).

It is critically important that all devices were connected to the same networkIf your computer uses Ethernet and your TV uses Wi-Fi from the same router, this is acceptable. However, if the networks are different (for example, your PC uses a cable provider and your TV uses a mobile hotspot), AllShare won't work. Also, check your router. AP Isolation mode is not activated - it blocks interaction between devices on the local network.

⚠️ Attention: On some router firmware (for example, Keenetic or ASUS Merlin) function Multicast may be disabled to save resources. If the TV doesn't detect the computer, go to the router's web interface and check the settings. IGMP Snooping or Multicast Forwarding.

2. Setting up your TV to work with AllShare

First, prepare your TV. The menu interface may differ depending on the year of manufacture, but the general procedure is the same. If you have a model Samsung 2015 or newer, look for the section Screen Mirroring instead of AllShare.

3. Setting up your computer for AllShare

On the PC side you need to configure DLNA server — software that will distribute content over a local network. There are two main methods: through proprietary software Samsung or using standard Windows tools.

Method 1: Samsung PC Share Manager

This is the official decision from Samsung, but it doesn't always work reliably on newer versions of Windows. You can download the utility from the support site. Samsung (search by TV model). After installation:

1. Launch Samsung PC Share Manager.
2. In the main window, click Settings → Add folders and specify directories with media files (movies, music, photos).
3. Enable the option Automatically start at logon (recommended).
4. Go to the tab Devices and check that the TV is displayed in the list.

Method 2: Windows Media Player (built-in DLNA)

If you don't want to install additional software, use the built-in Windows features:

1. Open Windows Media Player (part of the system).
2. Click Stream → Allow remote access to my media library.
3. In the window that appears, select Allow new devices to connect automatically.
4. Add folders with content via Library management.

After setting up the DLNA server, the TV should detect the computer in the list AllShare-devices. If this does not happen, check Windows Firewall - It may block network traffic. Add exceptions for Windows Media Player And Samsung PC Share Manager in security settings.

4. Connect via Wi-Fi Direct (alternative to AllShare)

If your TV supports Wi-Fi Direct (most models Samsung (2014 and newer) you can do without a router by creating a direct connection between your PC and TV. This method is useful if your home network is configured with strict restrictions or your router doesn't support Multicast.

Instructions for Windows 10/11:

2. Make a note of the network name (SSID) and password that appears on the screen.
3. On your computer, open Settings → Network and Internet → Wi-Fi.
4. Select your TV network (the name will include the model, for example, SAMSUNG-UE55KU6000) and connect by entering the password.
5. Launch Samsung PC Share Manager or Windows Media Player — the TV should appear in the list of devices.

The advantage of this method is more stable connection, since there is no intermediate node (router). However, data transfer speeds may be lower than with a regular Wi-Fi connection, especially if the TV and computer are in different rooms.

⚠️ Attention: When using Wi-Fi Direct, some Smart TV features (such as access to internet apps) may be unavailable because the TV is not connected to the main network. After streaming, remember to return to normal Wi-Fi mode.

5. Solving typical problems

  • Convert your file to a supported format using HandBrake.
• 🔄 Constant connection breaks:
  • Switch the router to a channel 5 GHz (less busy).
  • Reduce the distance between the router and devices.

• 📶 Select the correct Wi-Fi channel: use a network analyzer (eg Wi-Fi Analyzer for Android) and select the least loaded channel in the router settings.
• 🔧 Configure QoS on your router: Prioritize DLNA or media traffic to prevent other devices from hogging your bandwidth.
• 🖥️ Close background programs: torrents, cloud synchronization (Dropbox, Google Drive) and online games may load the network.
• 🔄 Limit video resolution: For streaming via Wi-Fi, the optimal resolution is 1280×720 (HD) instead 1920×1080 (Full HD) if the router does not support 802.11ac.

If you stream movies in high definition, consider wired connection TV to the router via an Ethernet adapter (for example, TP-Link UE300). This will reduce the load on Wi-Fi and improve stability.
