1. Checking basic settings: router and TV

Start with the obvious: Sometimes the problem lies in the little things that are easy to miss. The first thing to do is reboot both devicesUnplug your TV for 30 seconds, then unplug your router for the same amount of time. This will clear the network cache and any temporary errors.

If you still have no Wi-Fi connection after rebooting, check:

  • 🔌 Router power supplyIs the power indicator on? The power supply may be faulty or the cable may be damaged.
  • 📶 Network operating mode: Some TVs (especially older models) do not support modern standards Wi-Fi 6 (802.11ax). Try switching the router to the mode 802.11n (2.4 GHz).
  • 🔒 Network visibility: in the router settings (192.168.0.1 or 192.168.1.1) Check if the SSID (network name) is hidden. The TV will not be able to connect to a hidden network without manually entering the data.

Pay special attention broadcast channelIn densely populated areas, canals 2.4 GHz (e.g. 6 or 11) may be overloaded. Use apps like Wi-Fi Analyzer (For Android) or NetSpot (For Windows/macOS) to find the least loaded channel and set it manually in the router settings.

⚠️ Attention: If you use dual-band router (2.4 GHz + 5 GHz), try disabling network separation. Some TVs (for example, Samsung Series 6/7 2018–2020) don't work well with separate SSIDs for each band. Combine the networks into one with the same name.

Restart your TV and router|

Check if the Wi-Fi indicator on the router is on|

Make sure the network is not hidden (SSID broadcast is enabled)|

Try connecting to a 2.4 GHz network instead of 5 GHz|

2. Authentication errors: password, security type, and MAC filtering

One of the most common reasons is Incorrect password or incompatible security typeThe TV may not connect if:

  • 🔑 The password contains Cyrillic characters or special signs (For example, #, $, !). Some models LG And Philips do not process such characters correctly.
  • 🛡️ It's enabled in the router WPA3, and the TV only supports WPA2This applies to devices older than 2019.
  • 🖥️ Enabled MAC filtering, and your TV's address is not whitelisted.

To check these parameters:

  1. Open your router's control panel (usually at 192.168.0.1 or 192.168.1.1).
  2. Go to the section Wireless → Security (or similar).
  3. Install security type on WPA2-PSK (AES) - this is the most universal option.
  4. If used MAC filtering, find the MAC address of the TV in its settings (Settings → Network → Status) and add it to the list of allowed devices.

For TVs Sony Bravia (especially models X90J, X85J) there is another feature: they can conflict with routers TP-Link And ASUS, if enabled in the settings AI Protection or Parental ControlTry temporarily disabling these features.

Security type Compatibility with TVs Recommendations
WPA3 2020 and newer models only (Samsung Q80T, LG CX) Switch to WPA2 or update your TV's firmware
WPA2-PSK (AES) All models after 2012 The optimal choice for most devices
WPA2-PSK (TKIP) Obsolete models (before 2015) Unsafe, use only if no alternative
WEP Very old TVs (before 2010) Do not use - vulnerable to hacking
