Are you trying to show your vacation photos on the big screen, but your router is in another room, and the Wi-Fi signal in the "dead zone" barely reaches even your phone? Or do you want to stream a movie from YouTube on Samsung QLED, but the TV can't see your smartphone because of the thick walls? This problem is familiar to many: even in an apartment with a modern router, there's always a spot where the Wi-Fi is intermittent and the broadcast constantly drops.

In this article - 5 proven methods Transfer images from your phone to your TV via Wi-Fi, even if the signal is weak or unstable. We'll cover:

• 🔌 Direct connection Without a router (Wi-Fi Direct, Miracast) - when you don't need the internet at all
• 📶 Signal Boosting for areas with poor coverage (repeaters, mesh systems, 5 GHz vs. 2.4 GHz)
• 🖥️ Hidden settings Smart TVs that speed up streaming (power saving, traffic priority)
• ⚡ Workarounds for older TVs without Wi-Fi (adapters, HDMI converters)

All methods have been tested on devices from 2020–2026 (Samsung Galaxy S22, iPhone 14, LG OLED C2, Xiaomi Mi Box S). If your model is older, check the compatibility at the end of the article (there's a table with protocol support by year).

1. Wi-Fi Direct and Miracast: Stream without a router

If your TV and smartphone support Wi-Fi Direct or Miracast, you can create direct connection between them—without the need for a router. This is ideal for areas with poor signal strength because:

• 📵 Doesn't depend on internet quality - devices connect directly
• 🔒 No lag - perfect for gaming and video
• 🔌 Works even if the router is turned off

How to enable:

1. On Android: open Settings → Connections → Wi-Fi Direct or Screen → Wireless Display (the name depends on the model).
2. On Smart TV: go to Settings → Network → Wi-Fi Direct or Screen → Miracast.
3. Select the TV from the list of available devices on your phone and confirm the connection.

⚠️ Attention: On iPhone Miracast isn't working - Apple uses its own protocol AirPlayTo stream to a non-Apple TV, you will need an adapter (for example, Apple TV 4K or AnyCast).

Does your phone support Miracast? (Android 4.2+)

Does the TV have "Screen Mirroring" or "Wi-Fi Direct" function?

Is power saving mode disabled on both devices?

Is the distance between the phone and TV no more than 5 meters?

2. DLNA and Smart View: Streaming Media Files

If you need to transfer only video, music or photos (not the whole screen), use the protocol DLNAIt's less demanding on Wi-Fi speed and works even with a weak signal. The main thing is that both devices are connected to one network (even if it is unstable).

Instructions for Android:

1. Install the application BubbleUPnP or LocalCast.
2. Open the file in your gallery or file manager, click "Open with" and select a DLNA app.
3. In the list of devices, select your TV (it should appear as Samsung-6-Series, LG_webOS_TV etc.).

For iPhone/iPad:

• 🍎 Use the built-in function Screen mirroring (Swipe Center → Screen Mirroring)
• 📺 Or apps TV Assist, AllConnect (DLNA supported)

⚠️ Attention: Some TVs (especially Sony Bravia DLNA (2018–2019) blocks DLNA for "uncertified" apps. In this case, resetting the network settings on the TV will help:

Settings → Network → Reset network settings → Confirm

Why is DLNA slow?

If the video freezes, the problem may be:

- CodecsThe TV doesn't support the file format (e.g., MKV with HEVC). The solution is to convert it to MP4 (H.264).

- Bitrate: High quality settings (e.g. 4K 60fps) require a Wi-Fi speed of at least 30 Mbps. Reduce the resolution to 1080p.

- Background tasks: Close all applications on your phone and TV except the player.

3. Boost Wi-Fi for stable streaming

If the signal in the broadcast area is weak, even Miracast and DLNA will work intermittently. Here 3 ways to improve coverage without cable laying:

The fastest way is switch the TV to the 5 GHz band (if he supports it). To do this:

1. On TV: Settings → Network → Wi-Fi → Advanced → Bandwidth → select 5 GHz.
2. On the router: turn on Smart Connect (automatic switching between 2.4 and 5 GHz) or create a separate network for 5 GHz.

Critical detail: Samsung TVs from 2016–2018 (J, K, M series) do not support 5 GHz in Miracast mode; they only support internet. Check the documentation for your model!

4. Using adapters for TVs without Wi-Fi

If your TV was released before 2015 and does not have built-in Wi-Fi, you will need external adapterHere are 3 options:

• 📱 Google Chromecast (from 3,500 ₽) — connects to HDMI, supports Miracast and DLNA. Cons: requires a stable Wi-Fi connection.
• 🔄 AnyCast / MiraScreen (from 1,200 ₽) — works as a Miracast/AirPlay receiver. Pro: no internet connection required.
• 🖥️ Android TV Box (from 4,000 ₽, for example Xiaomi Mi Box S) is a full-fledged OS with support for all protocols.

How to connect AnyCast:

1. Insert the adapter into the HDMI port of the TV and connect the power supply (via USB from the TV or from the network).
2. Turn on your phone Screen Mirroring (Android) or Screen Mirroring (iPhone).
3. Select the adapter name from the list of devices (usually AnyCast-XXXX).

⚠️ Attention: Cheap adapters (under 1,000 ₽) often have a 1-2 second delay and don't support HDMI audio. Check reviews before purchasing!

5. Hidden Smart TV settings to speed up streaming

Even if your Wi-Fi connection is stable, your TV may artificially slow down the streaming due to power saving settings or network restrictions. Here's how to optimize it:

• ⚡ Disable power saving mode: Settings → General → Eco Mode → Disable. This will eliminate lag during video transmission.
• 🔀 Enable traffic priority: On the router (for example, TP-Link or ASUS) find QoS and add the TV's MAC address to the priority devices.
• 🔄 Update firmware: Outdated software may not support new codecs (such as AV1). Updating resolves 70% of streaming issues.

For LG webOS:

Settings → All settings → General → About TV → Update now

For Samsung Tizen:

Settings → Support → Software Update → Update Now

6. Alternative methods: if Wi-Fi doesn't work at all

If there is no Wi-Fi in the broadcast area or it is completely unstable, consider wired and hybrid solutions:

• 🔌 HDMI cable + adapter: For Android — USB-C to HDMI (from 800 ₽), for iPhone — Lightning to HDMI (from 2,500 ₽). Cons: the phone's battery drains faster.
• 📡 Powerline adapters: The Internet is transmitted through electrical wiring (for example, TP-Link TL-PA4010). Speed ​​up to 500 Mbps, but sensitive to wiring quality.
• 📶 4G/5G router: If the problem is weak home Wi-Fi, connect the TV to a mobile router (for example, Huawei E5577).

⚠️ Attention: When using USB-C to HDMI on Samsung Galaxy The sound may not work. The solution is to enable it in your phone settings. Transmitting audio via HDMI (Settings → Sound → Advanced).
