Samsung TV cannot find wireless network

Finding problems with a WI-FI router

If you are having difficulty connecting to a wireless network, the router settings may be incorrect. To change them, go to the control panel. Click the DHCP tab and make sure the DHCP server is enabled and working properly. Disabling it will not automatically assign a local IP address to the TV and other network devices. Normal routing and internet access will not be possible.

samsung, cannot, find, wireless

Check the “Security” tab in the router settings. If client MAC filtering is enabled, disable it. On routers ASUS, TP-Link, D-Link, Huawei and some other manufacturers, the MAC address of any device can be whitelisted. In the future, the connections of devices from this list will not be blocked, so the normal operation of WI-FI on the TV will be restored.

The MAC address of Smart TV is specified in the settings. The exact path differs depending on the brand, on most TVs of popular manufacturers, the necessary information is in the menu:

  • Samsung: “Support. Contact Samsung. Arrow to down. Wireless MAC “.
  • LG: “Setting. Support. Product Information “.
  • Philips: “Installation. Manual network configuration. View network settings. Start”.

Important! After adding MAC address of Smart TV to the “white list” or changing other parameters of the router, restart it. To do this, use the menu item “System” or “System Tools”. You can also use the power button on the case or temporarily disconnect the device from the outlet.

Manually specifying connection data

Using the built-in Smart TV menu, go to the WI-FI connection options. Select the manual mode for specifying settings if the DHCP server is disabled on the router, and the connection with automatic parameter detection does not work. In the “IP address” line, enter any IP from the local range. Valid start and end addresses are available for clarification in the admin panel of the router.

In the “Subnet mask” field, you must specify which part of the IP range will be used to address clients on the local network. The common value for this parameter is In the “Gateway” line, enter the IP address of the router, which is used to enter the settings.

Advice! The subnet mask and gateway can also be checked through any computer connected to your router. To do this, select Command Prompt from the context menu of the Start button. In the window that opens, enter the command: “ipconfig / all” and press “Enter”.

Replacing the WI-FI adapter with an external one

This method will not correct any problems with the internal radio. But if it is because of them that errors occur when connecting, use an external device. The form factor of such a WI-FI adapter resembles an ordinary USB flash drive. Like most other devices, it works when connected to a TV via USB.

On sale there is another type of adapters for receiving WI-FI. They have an external multi-directional antenna that provides better signal reception from the router. It is recommended to connect such modules via a USB extension cable, placing them at some distance from the TV. Thanks to this connection, interference from a working Smart TV will be minimized, and the data exchange speed will increase.

Important advice! Before purchasing an external adapter for connecting to a wireless network, check the list of supported devices in the instructions. This information can also be found on the manufacturer’s website or in technical support.

Changing the location of the router

Problems with the wireless network on the TV may be due to poor signal reception from the router. If possible, move the router closer to the Smart TV and install it so that there is less interference in the path of radio waves. Signal barriers are walls, furniture, and working appliances.

Installing an access point on an elevated level will help ensure a better WI-FI connection. For example, you can put the router on a closet or hang it over the door. If you cannot move the router closer to the TV, connect a more powerful antenna to it. The higher the antenna gain, the better the network will work on Smart TV.

Top 10 Ways to Check and Repair Wi-Fi on TV

There are 10 main ways to restore WI-FI to work on modern TVs. Most of them are related to correcting wireless settings. Required settings on Samsung, LG, Panasonic and Sony devices can be changed at home without contacting a service center.
Let’s take a look at all the main ways to fix configuration errors in turn:

Resetting your TV

A quick way, which in some cases helps to solve problems with WI-FI operation on Smart TVs, is to restore factory settings. Before executing it, it is advisable to rewrite the values ​​of the main parameters not related to the network. After the reset, you can get them back based on the recorded information. Menu path for restoring factory settings on popular TV models:

Samsung LED Smart TV Restarting On Its Own. Wifi Not Working. Samsung TV Support

  • LG: “Settings. Additionally. Are common. Factory reset “.
  • Samsung: “Support. Self-diagnosis. Reset “.
  • Panasonic: “Settings. System menu. Initial settings “.

Note! Factory reset will return more than the default network settings. Picture, sound, power saving and other Smart TV settings will not be saved.

Reboot TV and router

The first steps that need to be taken if WI-FI does not work on the TV is to reboot the Smart TV and the router. The malfunction can be programmatic and can be easily corrected by reinitializing the device drivers. To restart the TV, turn it off and on again. Some experts also recommend removing the plug from the electrical outlet and then plugging it back in. This advice makes sense for those TVs that remain connected to the local network even after the screen is turned off.

During the reboot of the router, you must wait 10-20 seconds between turning off and on. During this time, the previous Internet session will be closed on the provider’s side. Therefore, the connection will be made anew, with the settings reset to zero. When Smart TV and router turn on again, try to connect WI-FI.

Using a different WI-FI connection method

If you established the connection by manually entering the password from the wireless network, try connecting via WPS. WI-FI Protected Setup technology allows you to activate the fast connection mode in the TV settings. After that, a similar mode must be activated on the router. This is done through the control panel or a dedicated button on the back of the case.

To access the router’s web interface, turn the device over and find the login sticker. It is usually located on the bottom side and indicates the standard IP address, username and password. Enter the IP in any browser and enter the account information available on the sticker. Then go to the “WPS” section and activate this function. Fast connection will be available within 1-2 minutes.

In the case when the WPS protocol was used initially, but at the moment the connection cannot be established, enter the information manually. When connecting to a hidden network, you will need to specify not only the access key, but also the WI-FI name (SSID). TVs with earlier firmware versions do not always support Hidden Network Search. Therefore, before updating the software, it is recommended to remove the hiding of the network name in the router settings.

Transmitter technical problems

The next reason is on the transmitter side. The absence of a signal can be corrected in two ways:

  • If using cable TV, use a multimeter and check all the contacts, right down to the shield. You may need to contact a company to troubleshoot a problem that maintains your home and provides access to television.
  • Do you use satellite or terrestrial television? Contact your provider. Probably, planned technical work is underway or an accident has occurred due to weather conditions, which is already being corrected by specialists. Visit the official website of the operator, usually there they always update information and notify customers about preventive maintenance.


The equipment is connected first. Make sure you have followed this procedure correctly. Also check if it supports the required DVB-T2 broadcast format. Previously, this standard was not available in Russia, it was borrowed from Europe, and is used to watch digital TV. Outdated equipment will not be able to receive the desired DVB signal.


Does the device only detect analogue channels? Check cable and inputs for continuity. If the TV set does not find broadcasts, then first of all you need to check the cables. Everything is fine? We look at the following reasons.

If you have any questions or complaints. let us know

How to set up channels correctly

Can’t tune digital TV on LG? Make sure the setup is correct. Usually the search procedure is the same for all modern TV models. The only difference is in the names of the menu items. First, let’s look at the instructions for new LG TVs with Smart TV:

  • After connecting the equipment, on the remote control press the Setting button, which will open the parameters.
  • Click on the “Channels” tab and go to “Search” as indicated in the screenshot.
  • In the list, select the first option. Terrestrial TV (DVB T / T2 and analog).
  • If you are only interested in digital broadcasts, then check the box next to the corresponding item.
  • The system will start an automatic search and show the detected broadcasts.

The device did not find all TV channels? Change the position of the antenna and repeat the auto search.

If your TV does not support Smart TV:

  • Open the settings and go to the “Channels” tab.
  • Select “Autosearch”.
  • Check the box next to “Terrestrial TV” and “Digital only”.
  • Click “Next”.
  • Finally, make sure the device has found all channels.
  • Click “Close” to save the settings.

Why LG TV Won’t Find Terrestrial Digital Channels: Reasons What To Do?

In 2021, a TV is available in every apartment. If earlier simple devices were popular, now models with Smart TV technology are mainly used. But, sometimes the technique in question fails. What to do if LG TV cannot find digital channels? In the article, we will study the procedure for searching for TV broadcasts, consider common mistakes and solutions.

Search setting

It is important to specify the search parameters correctly. Earlier in this article, we covered the procedure for setting up a search. Use the instructions. One solution is to change the country.

Software glitches

Often times, a system crash is due to the users themselves. Why? Usually, incorrectly specified parameters are to blame. For example, an incorrect frequency has been entered, or the installed software in the receiver is no longer supported by the developer and now does not receive the necessary updates. In this case, you will need to reinstall the software.

Resetting the parameters to the factory settings can also eliminate the system failure. In the settings, select the appropriate item and wait for the system to complete the procedure. After reset, you will need to search for channels again.

Why Samsung TV Can’t Find Digital Channels Through Antenna, Cable

In some situations, the automatic channel search does not produce results, which indicates a malfunction. The error can be hidden in signal reception, connection, set parameters, software failure, or mechanical damage. Below we will study the existing problems in detail and analyze the ways to fix them.

Why Samsung TV Can’t See Digital Channels: Reasons What to Do?

Samsung TV cannot find digital channels. a common problem among viewers. Most of the problems are fixed on their own and do not require repair at the service center. But, in order to fix the problem on your own, you need to find out the reason.

Search setting

Search customization is often the cause of the issue in question. If the automatic search did not return any results, use the manual one. Do not forget to specify the parameters in the form of connection type, change the country, etc. Use the instructions attached at the beginning of the article.

Hardware connection problem

Samsung TV won’t pick up digital channels? Check if the connection is correct. Take your time to tune the digit. First, make sure you have connected all the hardware correctly. For example, a decimeter antenna, implying a built-in amplifier, must be connected to a receiver, which in turn is connected to the TV itself.

If you have any questions or complaints. let us know


Make sure the connected equipment can receive the broadcast format you want. DVB-T2 is a European digital TV standard that has been adopted in our country. That is, if you cannot use the new format and watch digital broadcast, then your equipment is probably outdated and cannot broadcast the accepted DVB-T2 standard.


Make sure the cable is intact and also check that the connection is correct. If earlier the TV showed channels without interruption, and now it shows no more than 10 broadcasts, then it is likely that preventive work has begun on the side of the provider. Usually, if the cable or inputs are damaged, the telly shows nothing at all.

Why won’t digital channels be tuned in to my Samsung TV

  • Software glitch.
  • Improper antenna or equipment connection.
  • Damaged cable.
  • Technical problems on the provider’s side.
  • Incorrect setting.

Using a cable connection

A breakdown of the radio module in the TV is the main reason why the previous tips may not help solve the problem. If you have tried all the ways to solve problems with WI-FI, most likely there is a malfunction at the hardware level. It is recommended to take the device to a service center. Within the warranty period, the replacement of the WI-FI module will be performed free of charge.

If it is not possible to take the device to a workshop, you can use a cable connection. To do this, plug one end of the power cord into the “LAN” port on the router, and connect the other to the TV. Routers usually have 2-4 Ethernet outputs, you can use any of them to connect a TV.

Most modern routers divide the Internet channel equally for all connected devices. But, for example, viewing multimedia content on Smart TV requires a very long wait in this case.

That is why, along with other optimized HD TV accessories, Samsung‘s CY-SWR1100 WI-FI router with the “Samsung’s Auto Prioritized QoS” function was released. It is with its help that streaming content receives the highest priority and, accordingly, the highest data transfer rate to your TV.

Resetting TV and router settings

Resetting the network parameters is quite simple. As an example, let’s take a look at the step-by-step instructions for Samsung Smart TV:

  • Turn on the TV device.
  • Press the buttons quickly in the appropriate sequence: Info, Menu, Mute, Power to open the system menu.
  • Select the “Option” section by pressing the Enter button.
  • Activate the “Factory Reset” function.
  • Turn off the TV to close the service menu.

Turn on the TV and re-configure the device, having previously changed the name of the home network and the password to it.

If you still can’t connect to Wi-Fi, do the following:

  • manually change the DNS value to parameters: or First you need to disable the “DHCP” option on the router;
  • open the main menu, and then the section “Control”, switch to the subsection “Sub Option”, and then to the tab “RF Mute Time”. Set the frequency with which you will switch to the next TV channel (you need to specify the time in milliseconds). Initially set to 600 milliseconds.

If you are still not connected to the network via Wi-Fi, you need to reset the router settings. It is very easy to do this, but you should only do it if you are sure that you can configure it again. When turning on the router, press and hold the WPS / Reset button (about 10 seconds) until the SYS indicator starts flashing quickly. Release the button and wait for the device to roll back to the basic parameters.

Quick guide for connecting Samsung TV to Wi-Fi

To determine the causes of problems with connecting to wireless networks, you must first carefully study the main features of setting up a Wi-Fi interface. It cannot be ruled out that the TV is not connected to the router due to incorrect user actions. Follow the simple instructions:

  • Turn on the router.
  • Take the remote control and open the main menu of the TV.
  • Go to the “Network” subsection, and then select “Network Settings”.
  • Choose the best connection method. “Wireless Connection”.
  • Connect to your home wireless network.
  • Enter your password and click “OK”.

The step-by-step guide clearly demonstrates that connecting to the Internet via Wi-Fi is a very simple and straightforward process. Users shouldn’t have any problems.

What to do if the Internet was there, but then stopped working? It is necessary to determine the cause of the failure. Based on this, remedial measures are determined.

IEEE 802.11 ac standard: what gives 5 GHz frequency?

Most routers distribute wireless Internet at 2.4 GHz. the same frequency that phones and microwaves emit their waves. This frequency was allocated as a working frequency for the old standards of wireless communication. IEEE 802.11 versions b, g, n.

Since 2009, Wi-Fi standards have gradually begun to use another frequency. 5 GHz, and in 2016 the Ministry of Communications of the Russian Federation officially allowed the use of the 5 GHz band for wireless Internet access. 5 GHz frequency support first appeared in the 802.11n standard and became permanent in the latest version. 802.11ac, with which the most current routers work today.

The new standard is backward compatible with the old ones, so devices that support 802.11ac are able to distribute the Internet in two frequency ranges: 2.4 and 5 GHz. Thus, all gadgets can be connected to them. both new ones that “understand” the 5 GHz frequency, and old ones that can only catch Wi-Fi in the 2.4 GHz range.

Here are the main advantages of a router that operates on the 802.11ac standard at 5 GHz.

  • Huge bandwidth. up to 160 MHz.
  • MIMO technology. Wi-Fi signal can include up to 8 spatial streams, while at 2.4 GHz there can be only 3.
  • Beamforming technology. the router detects where the device that is using the network is located and directs the signal from the antennas directly to it.

What does this mean in practice? With support for a large number of high-frequency channels, high bandwidth and smart search for connected devices, a Wi-Fi router with support for 802.11ac is capable of delivering sky-high Internet speeds. up to 7 gigabits per second.

Reboot TV and router

The first steps that need to be taken if WI-FI does not work on the TV is to reboot the Smart TV and the router. The malfunction can be programmatic and can be easily corrected by reinitializing the device drivers. To restart the TV, turn it off and on again. Some experts also recommend removing the plug from the electrical outlet and then plugging it back in. This advice makes sense for those TVs that remain connected to the local network even after the screen is turned off.

During the reboot of the router, you must wait 10-20 seconds between turning off and on. During this time, the previous Internet session will be closed on the provider’s side. Therefore, the connection will be made anew, with the settings reset to zero. When Smart TV and router turn on again, try to connect WI-FI.

Configuring the router itself

Setting up a Samsung router is quite simple thanks to a convenient, intuitive interface, which is not much different from the menu of similar WI-FI models from other companies. Let’s consider an indicative order of actions.

  • We find in the computer in the control panel “Network Connections”, we find our “Local Area Connection”, with the right mouse button we call the sub-item “Internet Protocol TCP \ IP”. Calling the item “Local Area Connection”
  • We choose to automatically obtain IP and DNS server addresses. Internet Protocol Configuration
  • We connect the cable of our Internet provider to the router in the WAN connector, which is an Ethernet network port. Router connectors
  • In any internet browser, enter This will bring up the menu for entering the router settings.
  • We enter there the username and password specified in the instructions for the router.
  • Go to the manual setting mode and select the “Parameters” item.
  • In the item “Internet Connection Type” select “Russia PPPoE (Dual Access)”.
  • In it we specify Dynamic PPPoE, enter the login and password, the network MAC address, the rest is by default.
  • We save the settings.
  • Turn on DHCP.
  • We make local network settings, here you need to enter the ip address of the router and the name of your network, the rest can be left by default or set to auto.
  • We save the settings.
  • Setting up additional services.

Note: when configuring additional services, do not forget to activate “Auto Prioritized QoS”.

A router with 5 GHz support: how it is useful now?

All of the above, of course, sounds very cool. But in reality, such an Internet does not yet exist. at least to the extent that it can be called publicly available. Modern Russian providers offer tariffs for a maximum of 1 Gbit / s, and even those are mainly in the capital.

If you are lucky enough to be a subscriber of one of the fast tariffs, then a router with 802.11ac support, tuned to a frequency of 5 GHz, is a must for you. Otherwise, you simply will not get your gigabit. at 2.4 GHz, about half the speed will be “cut off”.

In addition, the 2.4 GHz band is now overloaded: many routers, all Bluetooth-enabled devices, as well as a host of other equipment, including microwaves, work in it. Naturally, they compete with each other, interfering with each other‘s work.

2.4 GHz router and microwave oven work on the same frequency

Only Wi-Fi works at 5 GHz. So even if your tariff is not very high, you can buy a dual-frequency router and turn on the distribution of the Internet on it in the 5 GHz range. Then your devices that can “catch” Wi-Fi at this frequency will be able to freely use the Internet without interference.

Speaking of interference, the 5 GHz Wi-Fi signal is shorter, and this is a real gift in an apartment building. Your Wi-Fi will only work inside your apartment and will not be disturbed by the neighbors’ routers. Most likely, the neighbor will not even see your network in the list of available ones (and will not be able to hack it).

Finally, with support for MIMO and Beamforming technologies, each of your 5 GHz devices will receive a stable signal on a separate channel pointed directly at it. Therefore, despite the lack of speeds, it is already very profitable to use a 5 GHz router.

Home router 5 GHz: main functions and capabilities

As we said, a regular router that supports the 802.11ac standard works with the older b / g / n standards as well. Devices equipped with Wi-Fi modules of different generations will be able to connect to its network. from an old wireless printer to a flagship smartphone. In most cases, a home dual-frequency Wi-Fi router is equipped with multiple antennas for better signal transmission. On average, such a device is capable of providing a maximum wireless communication speed of 800 Mbps.

A consumer dual-frequency router usually has 2 to 8 LAN ports for wired connections. They have a standard bandwidth of 1000 Mbps within the local network. In addition, a 5 GHz router often has USB ports for connecting various devices, for example, a 3G modem to organize a mobile access point, or a USB drive for printing files to a network printer or sharing files over Wi-Fi.

For example, the popular Xiaomi Mi Wi-Fi Router 3G supports 802.11 b / g / n / ac standards and is equipped with four antennas for better signal transmission using MIMO and Beamforming. The maximum wireless speed of the router can be 1167 Mbps. and this is the average speed that covers the needs of the user, taking into account the capacities that Internet providers are able to provide.

In addition, the Xiaomi router has two Gigabit LAN ports and two USB ports. The device can operate as a file server, FTP server and print server, as well as a mobile access point, provided that a 3G modem is connected to one of the ports.
