⚠️ Please note: When using a guest WiFi network in hotels or offices, broadcasting may not work due to router restrictions that prohibit data exchange between client devices.
Connection stability depends on the frequency band. It is recommended to use a 5 GHz network if your router and receiver support it, as it provides higher throughput for HD and 4K contentThe 2.4 GHz band may be congested by neighboring networks, causing video buffering.

| DLNA | Maximum (original) | Absent | It is transmitted |
| Chrome Cast | Depends on the network | Average | Only from the tab |
| HDMI (cable) | Ideal | Absent | It is transmitted |
Troubleshooting and speed optimization
Even with proper setup, problems can still occur. A common cause is outdated wireless adapter drivers. Go to Device Manager, find your network adapter, and update the driver through the laptop manufacturer's website, not through the standard Windows driver.
If the image is pixelated, try lowering the screen resolution on your laptop before connecting. For example, changing from 3840x2160 on 1920x1080 can dramatically improve the smoothness of the stream if the router cannot cope with the load.
⚠️ Note: Samsung TV interfaces may vary depending on the year of manufacture and Tizen OS version. If you can't find the menu items described, please consult the official user manual for your specific model.
It's also worth checking your WiFi adapter's power-saving settings. In the adapter's properties in Device Manager, uncheck "Allow the computer to turn off this device to save power." This will prevent connection drops while watching long movies.
Why doesn't my Samsung TV detect my laptop when searching?
Most often, the problem is that the devices are connected to different frequency bands (guest network) or that AP Isolation is enabled on the router. Also, check if your antivirus software is blocking network detection.
Is it possible to stream 4K video without lag over WiFi?
Yes, this is possible, but only when using an 802.11ac (Wi-Fi 5) or 802.11ax (Wi-Fi 6) router in the 5 GHz band. For high-bitrate 4K HDR content, a cable HDMI 2.1 connection remains a more reliable option.
How to improve sound quality during wireless streaming?
In Windows sound settings, select the default format: 24-bit, 48000 Hz (Studio Recording). Make sure "Adaptive Sound" is enabled in your TV settings or a profile appropriate for watching movies is selected.
