Samsung — especially models of the series QLED, Crystal UHD or The FrameThe problem may occur after a firmware update, a power failure, or even for no apparent reason.

In this article, we'll look at all the possible reasons for Wi-Fi to disappear, from the mundane (like a disconnected router) to the technical (like a damaged wireless module). You'll get step-by-step instructions With illustrations, diagnostic checklists, and tips on how to avoid recurring problems. And if your TV is still under warranty, you'll find out when it's time to contact a service center. Samsung.

Important: Network recovery algorithms may differ depending on the TV year and version Tizen OSFor example, in models 2020–2022 The path to network settings is different from TVs 2023–2026We've taken these nuances into account and divided our recommendations by generation.

1. Check the obvious causes: router, cables, and power

Before you dig into your TV settings, make sure the problem isn't with your home network. 30% of cases Wi-Fi disappears due to external factors, not a TV malfunction.

Start with the router:

• 🔌 Reboot your router: Unplug it for 30 seconds, then plug it back in. Wait 2-3 minutes until the indicators light up normally.
• 📡 Check your Wi-Fi range: some TVs Samsung (especially older models) do not support networks 5 GHzSwitch the router to the mode 2.4 GHz or activate both ranges.
• 🔒 Make sure the network is not hidden: in the router settings (192.168.0.1 or 192.168.1.1) check that the option Hide SSID disabled.
• 📱 Test on other devicesConnect your smartphone or laptop to the same network. If the internet works, the problem is with the TV.

If the router is ok, inspect the TV:

• ⚡ NutritionUnplug the TV for 1 minute, then plug it back in. Sometimes Wi-Fi module issues can be resolved with a cold reboot.
• 🔌 Cables: if you use LAN adapter (for models without built-in Wi-Fi), check its connection to the port USB or Ethernet.

⚠️ AttentionIf, after rebooting the router, the TV still can't see the network, but other devices connect normally, the problem is definitely with the TV. Proceed to the next sections.

2. Firmware update: why it might help

Outdated software is one of the main causes of Wi-Fi problems. Samsung regularly releases patches to fix bugs, including network connection errors. For example, in the firmware T-MSMDEUC-1402.1 (2023) A bug with the Wi-Fi icon disappearing after waking up from sleep mode was fixed.

How to update firmware without internet (if Wi-Fi does not work):

1. Download the latest firmware for your model from the website. Samsung support (use PC or smartphone).
2. Unzip the file and copy it to empty flash drive (format FAT32).
3. Insert the flash drive into the port USB TV.
4. Go to Settings → Support → Software Update → Update Now.
5. Select an option Update from USB and follow the instructions.

If the TV is still connected to the network via cable Ethernet, the update can be run directly:

Settings → Support → Software Update → Online Update

⚠️ AttentionDo not turn off your TV during the update! If the process is interrupted, the TV may not turn on. In this case, you will need to reflash the firmware using service mode.

What should I do if my TV is stuck on the update screen?

If the indicator is lit but the update hasn't started for more than 20 minutes, unplug the TV for 5 minutes and then plug it back in. If this doesn't help, contact a service center: interrupting the update yourself may damage the firmware.

3. Resetting network settings: step-by-step instructions

If updating the firmware doesn't help, the next step is to reset the TV's network settings. This will delete all saved networks and return the connection settings to factory defaults.

Instructions for Tizen OS (2016–2026 models):

1. Open Settings (button Home on the remote control → gear ⚙️).
2. Go to the section General → Network Settings.
3. Select Network reset (or Restore network settings to factory defaults).
4. Confirm the action by entering the PIN code (by default 0000 or 1234).
5. After rebooting, try connecting to Wi-Fi again.

For older models (2015 and earlier) the path may differ:

Menu → Network → Network Settings → Reset

If after resetting the networks are still not showing, check:

• 🔍 Regional settings: Wi-Fi range is limited in some countries. Make sure Russia is selected in your TV settings (Settings → General → Language and Region).
• 📶 Wi-Fi channel: in the router, try changing the channel from automatic to fixed (for example, 6 or 11 For 2.4 GHz).

4. Checking hardware faults: Wi-Fi module and antenna

If software methods do not work, the problem may lie in hardwareOn TV Samsung A separate module controls Wi-Fi, which eventually fails. Typical signs of failure:

• 🔴 The Wi-Fi icon is gray and inactive despite resetting the settings.
• 🔄 The TV "sees" the network, but does not connect (it says "Authentication error").
• 📉 The signal constantly drops, even if the router is nearby.

How to diagnose a hardware failure:

1. Check the antenna connection: in some models (for example, QLED Q70TThe Wi-Fi antenna is connected to the motherboard with a separate cable. If it becomes disconnected, there will be no signal.
2. Test with external adapter: connect to TV USB Wi-Fi adapter (For example, TP-Link TL-WN725N). If the network works with it, the problem is in the internal module.
3. Testing with a multimeter (for advanced users): check the resistance on the Wi-Fi module contacts. The normal value is 50–100 Ohm.

If the module is confirmed to be faulty, you have two options:

• 🔧 Replacing the module: the cost of a new Wi-Fi module for Samsung TV — from 1,500 to 4,000 rubles (depending on the model). You can replace it yourself if you have experience using a soldering iron.
• 🛠️ Contacting service: official centers Samsung They provide a repair warranty (from 3 months). The average cost of diagnostics is 500–1,000 rubles.

⚠️ AttentionOn TV Samsung series JU6400, KU6000 And MU6100 (2015-2017) the microcircuit often fails BCM4356 (Wi-Fi/Bluetooth module). Replacing it requires specialized equipment—we don't recommend doing it yourself.

5. Alternative ways to connect to the Internet

If you can't restore Wi-Fi, but you urgently need internet access on your TV, try these alternative methods:

1. Connecting via Ethernet cable

• 🔌 Connect the cable from the router to the port LAN on the back of the TV.
• 🖥️ In the network settings, select Wired connection.
• ⚡ The speed will be more stable than via Wi-Fi (especially important for 4K content).

2. USB Wi-Fi adapter

• 🛒 Buy an adapter with support Samsung TV (For example, Edimax EW-7811Un or TP-Link TL-WN725N).
• 🔌 Connect it to the port USB TV.

6. When to contact the service center

If none of these methods work and your TV still can't connect to Wi-Fi, the problem likely requires professional intervention. Contact a service center. Samsung in the following cases:

• 🔧 After the TV has fallen or been hit (the motherboard may be damaged).
• 🔥 If the TV overheats or turns off spontaneously.
• 📵 If there is not even a section in the network settings Wi-Fi (this indicates that the module is broken).

7. Prevention: How to avoid Wi-Fi problems in the future

To avoid Wi-Fi drops again, follow these tips:

• 🔄 Update your firmware regularly: Turn on automatic updates in Settings → Support → Software Update.
• ⚡ Use a voltage stabilizer: Power surges often damage the Wi-Fi module.
• 📡 Optimize your router's location: keep it no more than 10 meters away from the TV, without obstacles (walls, furniture).
• 🔒 Don't use complex passwords: some models Samsung TV do not support special characters (!, @, #) in the Wi-Fi password.
• 🔌 Reboot your router periodically: This clears the cache and prevents freezing.
