Smart TV Not Recognizing Wi-Fi: Causes and 10-Minute Fix

Your My smart TV suddenly stopped detecting Wi-Fi., although other devices connect without problems? This situation is familiar to many: a device that was just working Samsung QLED or LG OLED Suddenly, your home network connection becomes "blind," and the message "No networks available" or "Unable to connect" appears on the screen. The causes could lie in both the TV's settings and the router's parameters—from a simple firmware glitch to a standard conflict. Wi-Fi 5/6.

In this article we will look at all possible failure scenarios — from simple (rebooting the equipment) to complex (manually setting the router channels). You'll learn how to diagnose the problem, which parameters to check first, and what to do if the TV doesn't detect only your network, but finds neighboring ones. The instructions are suitable for models Sony Bravia, Xiaomi Mi TV, Philips Android TV and other brands on platforms Android TV, webOS And Tizen.

1. Checking basic parameters: router and TV

Start with the basic steps—they solve the problem in 60% of cases. Most often, The TV doesn't see Wi-Fi Due to a temporary malfunction of the router or the TV itself. Here's what to do:

• 🔄 Reboot your router: Unplug it for 30 seconds, then plug it back in. Wait until it boots up completely (the indicators should be steady).
• 📺 Restart your TV: Unplug the power cord for 1 minute (do not use the power button on the remote control - this is not a hard reset!).
• 📶 Check network visibility on other devicesIf Wi-Fi doesn't find your phone or laptop, the problem is with the router, not the TV.
• 🔌 Make sure Wi-Fi is turned on on your router.: on some models (TP-Link, ASUS) button WPS/Wi-Fi may be accidentally released.

If after rebooting the TV still doesn't see the network, but other devices connect, proceed to the next section. If Wi-Fi isn't working at all, the problem is with your router: check your settings or contact your ISP.

2. Setting up the Wi-Fi channel and standard on the router

One of the most common reasons why Smart TV can't find the network - incompatibility with the current router settings. Modern models (Samsung QN90C, LG C3) support Wi-Fi 6, but may conflict with:

• 📡 Too wide a channel (For example, 160 MHz instead of 20/40 MHz).
• 🔢 Automatic channel selection (the router can switch to a busy or prohibited channel).
• 🔒 Old safety standards (WEP instead of WPA2/WPA3).

To fix this:

1. Open your router's control panel (usually at 192.168.0.1 or 192.168.1.1).
2. Go to the section Wi-Fi → Wireless Network Settings (the name may differ).
3. Install:
   • Standard: 802.11n/ac/ax (or Wi-Fi 5/6).
   • Channel: 20/40 MHz (For 2.4 GHz) or 80 MHz (For 5 GHz).
   • Security mode: WPA2-PSK (or WPA3, if the TV supports it).

Save the settings and reboot the router.

Set Wi-Fi 5/6 (802.11ac/ax) standard|

Select a fixed channel (e.g. 6 for 2.4 GHz)|

Disable the "Auto Channel Selection" feature|

Set channel width to 20/40 MHz (for 2.4 GHz)|

Enable WPA2+WPA3 compatibility mode (if available)

-->

Important: If your TV was released before 2018 (for example, Samsung MU6xxx or LG UK6xxx), it may not support Wi-Fi 6 or channels of width 160 MHzIn this case, select Wi-Fi 5 (802.11ac) and the channel 80 MHz.
