How to Share a Folder on Windows 10 via Wi-Fi to Your TV: A Complete Guide

Do you want to stream movies, photos, or music from your computer to your big TV screen, but don't know how to set up sharing? This article will help you understand all the nuances of sharing folders. Windows 10 By Wi-Fi for modern Smart TV from Samsung, LG, Sony and other brands. We'll look at two main protocols: DLNA (for media players) and SMB (to access files as a network drive), and we will also look at typical errors that interfere with the connection.

It's important to understand that the process depends not only on Windows settings, but also on the TV model, its firmware version, and even the router. For example, some TV set-top boxes on Android TV require additional applications, while Samsung Tizen or LG webOS Support connection out of the box. In this guide, we'll focus on universal solutions that work in 90% of cases.

If you have previously tried to set up sharing but encountered problems (for example, the TV does not see the computer or asks for a login and password), pay special attention to the sections about access permissions And network discovery settingsWe'll also give you tips on optimizing your data transfer speed, which is especially relevant for videos in 4K or HDR.

1. Preparing Windows 10: Network Settings and Protocols

Before sharing folders, you need to make sure your computer and TV are on the same local network and the required services are enabled in Windows. Let's start with the basic checks:

• 🔌 Connecting to one network: Make sure both your PC and TV are connected to the same router (via Wi-Fi or cable). Check this in Control Panel → Network and Internet → Network and Sharing Center on the computer and in the menu Net on TV.
• 🔄 Network type: In Windows 10 it should be selected private (home) network, not public. This can be changed in Settings → Network & Internet → Status → Change connection properties.
• 🛠️ Windows Services: For work DLNA And SMB services must be running Host Provider, SSDP Discovery And UPnP Device HostTheir status is checked in services.msc (call the window Execute keys Win + R).

If you use antivirus (For example, Kaspersky, ESET or Avast), temporarily disable it firewall - it may block data exchange. Also, check if the built-in Windows firewall for private networks (settings in Control Panel → Windows Defender Firewall).

⚠️ Attention: If your router supports network separation for guests (Guest Network), make sure the TV and computer are connected to the main network. In guest mode, the devices cannot see each other.

2. Method 1: Sharing via DLNA (for media files)

DLNA (Digital Living Network Alliance) is a standard that allows you to stream media content (video, music, photos) to compatible devices, including TVs. Windows 10 uses a built-in feature for this. "Media Streaming".

To enable DLNA:

1. Open Control Panel → Network and Internet → Network and Sharing Center.
2. Select Change advanced sharing options.
3. In the section All networks find the item Media streaming and press Select media streaming options.
4. Activate the option Enable media streaming and, if necessary, set a name for your media server (it will be displayed on your TV).

Now all that remains is to add folders with media files to Windows libraries:

• 🎬 Open Conductor and go to the movies/music folder.
• Right click → Include in library → select Video, Music or Images.
• 🔄 If the folder doesn't appear in the library, click Organize → Folder Options → Restore Defaults.

On your TV, launch a media player app (e.g. Smart Share on LG, AllShare on Samsung or Media Player on Android TV). Your computer should appear in the list of devices. If it doesn't, check:

• 🔄 Restart your router and TV.
• 📡 Make sure it is not disabled in your router settings UPnP (usually in the section LAN or Home network).
• 🔍 Try manually updating the list of devices in your TV's media player.

3. Method 2: Sharing via SMB (for full access to files)

If you need not only to view media, but also full access to files (for example, to edit documents or run programs from a TV), use the protocol SMB (Server Message Block). This method allows you to map a folder as a network drive.

Setup instructions:

1. Right-click on the folder you want to share and select Properties → Access → Share.
2. Select a user from the drop-down menu All (or create a new one) and click Add.
3. Set permission level: Reading (view only) or Reading and writing (editing files).
4. Click General access, then go to the tab Security and repeat the permissions setup for the user All.

Now on TV:

• 📺 On Samsung Tizen: open My Files → Network Storage → Add Network Storage. Enter the IP address of the computer (you can find it out using the command ipconfig V CMD) and the folder name (for example, \\192.168.1.100\Films).
• 📺 On LG webOS: run File Manager, select Network Storage → Windows Share and enter the same data.
• 📺 On Android TV: install the application FX File Explorer or Solid Explorer, then connect to LAN/SMB.

⚠️ AttentionIf your TV asks for a login and password, use your Windows account credentials. If you don't have a password, create one in Settings → Accounts → Sign-in optionsFor security reasons, do not use a blank password!

4. Troubleshooting: Why the TV doesn't see the folder

Even with proper setup, problems can still arise. Here are the most common causes and solutions:

If none of the methods helped, check:

• 🔧 Router settings: some models (eg TP-Link or ASUS) are blocking SMB by default. Enable support in the section LAN → SMB/NetBIOS.
• 🔄 Firmware updates: on the TV and router. Outdated versions may not support modern protocols.
• 🛡️ Antivirus or VPN: They may be blocking network traffic. Try temporarily disabling them.

What should I do if the TV sees the folder but does not play the video?

This may be due to incompatible codecs. TVs usually support MP4 (H.264), MKV (H.265) And AVI (Xvid), but they don't work with MOV, FLV or rare codecs. Solution:

1. Convert video using HandBrake or FFmpeg.

2. Check the supported formats in the TV manual (Multimedia section).

3. If the file plays slowly, reduce the bitrate or resolution.

5. Optimizing Wi-Fi data transfer speed

When broadcasting video in high definition (4K, HDR) or large files, Wi-Fi speed becomes critical. Here's how to improve it:

• 📶 Wi-Fi frequency: Use range 5 GHz instead of 2.4 GHz - it is less congested and provides speed up to 1 Gbps (against 150–300 Mbps on 2.4 GHz).
• 🔄 Wi-Fi channel: In the manual settings of the router, select the least loaded channel (for example, 36, 40 or 48 For 5 GHz).
• 📡 Router location: Make sure there are no thick walls or metal objects between the router and the TV. The optimal distance is no more than 10 meters.
• 🔌 Connecting a computer via cable: If possible, connect your PC to the router via Ethernet - this will reduce the load on Wi-Fi.

Critical Information: If your router supports the standard Wi-Fi 6 (802.11ax), but the TV or computer is equipped with adapters Wi-Fi 4 (802.11n), the maximum speed will be limited by the weakest link. Check the device specifications in the documentation.

To test the speed, use the utility iPerf or online services like Speedtest.netIf the speed is lower 50 Mbps, try:

• 🔧 Switch to a different channel in the router settings.
• 📡 Update your router firmware (relevant for Keenetic, MikroTik, Zyxel).
• 🔄 Disable power saving for the Wi-Fi adapter in Device Manager (adapter properties → Power management).

6. Alternative methods: cloud services and third-party programs

If setting through DLNA or SMB causes difficulties, consider alternative options:

• ☁️ Cloud storage: Upload files to Google Drive, Yandex Disk or Dropbox, then open them through the app on your TV. The downside is that they're dependent on internet speed.
• 📱 Broadcasting apps:
  • LocalCast (Android TV) - supports transmission from a PC via a local network.
  • VLC - can act as a DLNA server.
  • Plex or Kodi — organize a full-fledged media server with transcoding.
• 🔌 USB driveConnect a flash drive or external hard drive to the TV. This method is reliable, but inconvenient for frequent content updates.

For Plex or Kodi You will need to install the server component on your computer. These programs automatically sort your media library, download covers and subtitles, and transcode videos on the fly to suit your TV's capabilities. However, they consume PC resources, so for weaker machines (such as laptops with Intel Celeron) it is better to use built-in Windows tools.

7. Security: How to protect shared folders

By sharing folders over the network, you risk unauthorized access. Follow these guidelines:

• 🔐 Complex passwords: If you use an account with a password, it must contain at least 8 characters, including numbers and special characters.
• 🚫 IP restriction: In the router settings (MAC/IP filtering) allow access to the local network only for the addresses of your devices.
• 🔄 Disabling guest access: In Windows sharing options, turn off the option Password-protected sharing (if you don't use a password).
• 📡 A separate network for IoT: Set up a separate network on your router for smart devices (including your TV) and restrict its access to computers.

If you share folders temporarily (for example, for a party), remember to turn off sharing after use. To do this:

1. Go to Control Panel → Administrative Tools → Computer Management → Shared Folders → Shared Resources.
2. Select the unnecessary folder and click Stop sharing.

⚠️ Attention: Some viruses (eg. WannaCry) are spread through vulnerabilities in the protocol SMBUpdate Windows regularly and disable SMBv1 (outdated version) in Control Panel → Programs → Turn Windows features on or off.

FAQ: Frequently asked questions about setup

The TV doesn't detect the computer, even though they're on the same network. What should I do?

Please check the following points:

1. Is it included? network discovery in Windows (Settings → Network & Internet → Sharing options).
2. Is the protocol allowed? SMB in the router settings (sometimes it is blocked by default).
3. Doesn't the TV use VPN or proxy, which may interfere with local connectivity.
4. Are the drivers updated? network adapter on the computer (check in Device Manager).

If nothing helps, try connecting the TV to the computer via HDMI or use USB drive.

Is it possible to share a folder without a password?

Yes, but it's not secure. To disable the password prompt:

1. Open Control Panel → User Accounts → Manage Accounts.
2. Select Change User Account Control settings and move the slider down.
3. In the sharing options (Settings → Network & Internet → Sharing options) select Disable password-protected sharing.

⚠️ WarningThis will make your folders accessible to all devices on your local network. Use only on trusted networks!

How do I find a computer's IP address for an SMB connection?

There are several ways:

• Through command line: click Win + R, enter cmd, then run the command ipconfigThe address you are looking for will be in the line IPv4 address.
• Through Control Panel: Network and Internet → Network and Sharing Center → Local Area Connection → Details.
• Through router: go to the router's web interface (usually at 192.168.1.1 or 192.168.0.1) and look at the list of connected devices.

If the IP address starts with 169.254, this means the computer hasn't received an address from the router. Restart the router or check the settings. DHCP.

Why does video lag when playing on a computer?

The reasons may be as follows:

• Slow Wi-Fi speed: check your connection speed (should be at least 20 Mbps For Full HD And 50 Mbps For 4K).
• Incompatible codec: Your TV may not support the video format. Try converting the file to MP4 (H.264).
• High computer load: if the PC is simultaneously transcoding video (for example, via Plex), this may cause lag. Close unnecessary programs.
• Router settingsSome routers limit the speed between devices on the local network. Check QoS (Quality of Service) in the settings.

For diagnostics, use the utility Wireshark or the built-in Windows Resource Monitor (Win + R → resmon).

Is it possible to share a folder to a TV via a mobile hotspot?

Technically yes, but it's inconvenient and unreliable:

• The data transfer speed will be limited by the speed of the mobile Internet (usually 10–50 Mbps).
• Traffic consumption: for 1 hour of video Full HD may go away before 3–5 GB.
• Lag: Due to an unstable connection, the video may slow down.

It's best to use a home router. If that's not possible, connect your TV to your computer via USB cable (if supported MHL) or HDMI.
