    • 📡 Wireless network (2018–2020 models)
    • 🔌 General → Network (old models)
  • Select your Wi-Fi networkIn the list of available networks, find the name of your router (for example, TP-Link_1234). If there is no network, press Refresh the list or Search for networks.
  • Enter your passwordUse the on-screen keyboard. Please note:
    • 🔤 Case-sensitive! Password Password And password - different.
    • 🔢 Numbers and symbols are entered by switching the layout (button 123 or Sym on the on-screen keyboard).

      Make sure the router is turned on and distributing Wi-Fi|

      Check the network password (if necessary, reset the router settings)|

      Connect the TV to the power supply (and One Connect Box, if available)|

      Update your TV firmware (if there is a notification about an available update) -->

      3. Alternative ways to connect to the Internet

      If your Wi-Fi is unstable or not fast enough to stream 4K-content, consider alternative options:

      Connection method Speed Pros Cons
      Cable (LAN) Up to 1 Gbps Maximum stability, no delays You need to pull the cable, tie it to the place
      Wi-Fi 5GHz Up to 866 Mbps High speed, less interference Shorter range, not all TVs support it
      Powerline adapter Up to 600 Mbps Uses electrical wiring, no need for cables Sensitive to wiring quality, expensive
      USB modem (4G/5G) Up to 300 Mbps Autonomous, suitable for a summer house Limited traffic, lags possible

      To connect via cable you will need Category 5e or 6 Ethernet cable. Connect one end to the router (ports are usually yellow) and the other to the jack LAN on TV or set-top box On Samsung QLED The port can be hidden behind a removable cover on the back panel.

      If you choose 5GHz Wi-Fi, make sure your TV supports this range. For example, models Samsung TU7000 (2020) work only on 2.4GHz, A QN90B (2022) support both bands. To switch to 5GHz, select the network with the postfix in the Wi-Fi menu. _5G (For example, MyWiFi_5G).

      4. Setting up a hidden Wi-Fi network on T2

      If your router is configured to hidden network (does not broadcast the SSID), connecting will require additional steps. This mode is often used for increased security, but it can cause compatibility issues with some devices, including Samsung T2 set-top boxes.

      Instructions for connecting to a hidden network:

      1. From your TV's Wi-Fi menu, select Other networks or Add a network manually (on some models - Entering SSID).
      2. Enter the exact name of the network (SSID) manually. Note that spaces and case are important! For example, MyHomeWiFi And myhomewifi - different networks.
      3. Select the security type. Typically this is WPA2-PSK or WPA3-PSKIf you are not sure, check in the router settings (section Wireless Security).
      4. Enter the password and save the settings. The TV should connect within 10-20 seconds.

    If the connection fails, check:

    • 🔍 Network visibility On other devices (smartphone, laptop). If they also can't see the network, the problem is with the router.
    • 🔄 Router operating modeSome models (for example, Keenetic) in "Access Point" mode do not support hidden networks for older devices.
    • 📱 TV firmwareOn . Samsung Series 6 (2017) There is a bug with connecting to hidden networks - an update to the version is required 1503.5 or higher.
    ⚠️ Attention: Hidden networks do not provide real security - their name is easily determined using traffic analyzers (for example, Wireshark). For protection, it is better to use WPA3 and a complex password.

    5. Optimizing Wi-Fi for stable T2 reception

    Even if the TV is connected to the network, you may encounter video freezing, slow download speed or constant connection breaksThis is due to the way wireless networks operate in interference-ridden environments. Here's how to improve your signal:

    Router settings:

    • 📶 Change Wi-Fi channelIn urban areas, channels 1, 6 And 11 (for 2.4GHz) are usually overloaded. Use the utility Wi-Fi Analyzer (Android) or NetSpot (iOS/macOS) to find a free channel.
    • 🔄 Enable 802.11n/ac mode. In the router settings (section Wireless Mode) select 802.11n/ac mixed instead of 802.11b/g/n - This will increase the speed for compatible devices.
    • 🛡️ Turn off Wi-Fi power savingOn some routers (for example, Xiaomi Mi Router) there is an option Wi-Fi Power Saving - it needs to be deactivated for stable operation with TV.

    TV settings:

    • 📺 Turn off automatic switching to mobile dataOn . Samsung Tizen go to Settings → General → Network → Use Mobile Data and deactivate the option.
    • 🔄 Enable static IPThis will help avoid DHCP conflicts. Path: Settings → Network → Network Status → IP Settings (select Manually and specify the IP from your router's range, for example 192.168.1.100).
    • 🔋 Turn off Eco ModeOn some models (for example, Samsung Q60C) This mode limits the performance of the Wi-Fi module.
    • Critical Information: If your TV supports Wi-Fi 6 (802.11ax), but your router only supports Wi-Fi 5 (802.11ac), force the TV to switch to compatibility mode. To do this, enter service menu (code INFO → MENU → MUTE → POWER on the remote control) and select Wi-Fi Mode: Auto instead of 802.11ax Only.
