• 📶 Router signal: The TV must be in a strong reception area. You can check the signal strength on your smartphone—if there are 1-2 bars, the TV will also be losing the network. Ideally, 3+ bars or ≥-60 dBm (checked using apps like WiFi Analyzer).
• 🔒 Wi-Fi password: If you forgot it, look at the router sticker (SSID and security key) or in the router web interface at 192.168.0.1 (logins admin/admin or admin/password from sticker).
• 🔄 Router operating mode: some models Samsung (especially 2019-2021) do not support encrypted networks WPA3In your router settings, temporarily switch to WPA2-PSK (AES).
• 📡 Wi-Fi channel: Avoid automatic channel selection - set it manually 6 or 11 for 2.4 GHz (they are less susceptible to interference from neighbors).

   • Subnet mask: 255.255.255.0.
   • DNS: use 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare) to speed up content loading.

Save the settings and restart the TV.

To check your connection speed, go to Settings → Support → Self-diagnostics → Network speed testOptimal values:

If the speed is below the minimum:

• 📶 Switch to range 5 GHz (if the router is dual-band).
• 🔌 Connect the TV to the router via cable (if possible) for testing.
• 🔄 Change the Wi-Fi channel in the router settings (use WiFi Analyzer to search for a free channel).

6. Troubleshooting connection errors

Even after proper setup, errors may still occur. Let's look at the most common ones:

If the TV connects to Wi-Fi, but no internet access:

1. Check if the Internet works on other devices.
2. Reboot your router (turn off the power for 30 seconds).
3. Reset DNS in TV settings: Settings → General → Network → IP Settings → DNS → Auto.
4. Update your TV firmware: Settings → Support → Software Update → Update Now.

⚠️ Attention: If your TV Samsung released before 2019, some features (eg Wi-Fi Direct or WPS) may be missing. Check the exact model name on the sticker on the back and refer to the official documentation on the website. Samsung Support.

7. Optimize Wi-Fi for streaming and gaming

To avoid lags while viewing Netflix in 4K or a game of Cloud Gaming (For example, Xbox Cloud or GeForce NOW), make the following settings:

• 🎮 Traffic prioritization (QoS): In your router settings, add the TV's MAC address to the list of priority devices. This will ensure that the TV always receives the maximum speed.
• 📶 5 GHz band: If your router is dual-band, connect your TV to the network. 5 GHz (less interference, higher speed). Manually select the desired network in the TV menu.
• 🔄 Disabling Wi-Fi power saving: in the TV settings go to Settings → General → Power Saving → Wi-Fi Power Saving Mode and turn off this option.
• 🛡️ Disabling IPv6: If you are having problems with streaming, try disabling IPv6 in the TV network settings (section IP settings).

To check the stability of the connection:

1. Run a speed test in Settings → Support → Self-diagnosis.
2. Watch the video on YouTube in resolution 2160p (4K) - if there is no buffering, the connection is stable.
3. Connect a gamepad and launch cloud gaming—input lag should be no more than 50ms.
