Why Smart TV doesn‘t see Wi-Fi in 5 GHz range?
There are a lot of Smart TVs on the market now, as well as dual-band routers that can distribute Wi-Fi at the same time at 2.4 GHz and 5 GHz. But it’s not uncommon for a TV not to see a Wi-Fi network in the 5 GHz band. It just can’t find it and it doesn‘t show up in the list of available networks. In this case, other devices usually find this wireless network and connect to it. Of course, to solve this problem makes sense only if your TV has support for Wi-Fi 5 GHz (standard 802.11ac) and you have a dual-band router. We are going to try to figure that out. I can only add that the manufacturer of the TV in this case does not matter. This problem is observed on LG Smart TVs (WebOS). Smasung, Sony, Philips, TCL, Kivi, Ergo, etc. д.
There are many reasons why a TV set can’t see wireless networks. I have written about some of them in this article (by the example of LG TVs). In this article we will look at the problem with connecting to networks in the 5 GHz band. Before you go to the problem and try to make your TV connect to Wi-Fi at 5 GHz, be sure to verify:
- That your TV has support for Wi-Fi 5 GHz (802.11ac). Very often people try to connect to a Wi-Fi router a TV which has no Wi-Fi, or does not support Smart TV (such TV can’t be connected to the Internet at all). Find out the model of your TV (look on the box, on the sticker). Type the model in a search engine, go to the official site of the manufacturer and look at the specifications. If it says it supports the 802 standard.If it’s 11ac, you’re sure your TV can connect to a network in the 5 GHz range. If 802.11n. probably not. Unfortunately not all manufacturers specify such detailed characteristics of the built-in Wi-Fi module. And on the various sites, or in online stores, most often this information is not specified at all (even if it is on the official site). In any case, knowing your TV model, you can always dial the manufacturer’s support number and ask.
- That you have a dual-band router and it broadcasts a Wi-Fi network in the 5 GHz band (it can be disabled in the router settings). That the name of a 5 GHz Wi-Fi network is usually distinguished by the prefix “_5G” in the wireless network name. Make sure that other devices (that support this band) are detecting your network and will connect to it. Why your laptop, smartphone, or tablet does not see the 5 GHz Wi-Fi network.
- That the TV is within stable 5GHz wireless network coverage. Don’t forget that compared to band 2.4 GHz, the range of this network is usually a little less.
If all three points are correct, the router broadcasts the desired network, and the TV should connect to it (but for some reason does not see it). you should try one solution that usually helps in this situation.
If TV doesn‘t connect to Wi-Fi line, first of all we check the equipment. router. To perform the task, it is enough to connect a cell phone or tablet to the network and check the performance of the mobile gadget. If there is a connection, the problem is in the regulation of the TV receiver.
Otherwise, the issue is a problem with the router or its network parameters. Also the failure is caused by technical works at the provider, for clarification contact the hotline.
There are other primary sources of failure, which are solved by separate approaches. What to do if the TV does not see Wi-Fi?
Check if the equipment is connected correctly
Most problems are related to the router itself or its physical connection to the wire from the service provider. To exclude this type of the problem it is necessary to make sure that the wires in the adapter are correctly placed in the WAN-port. Also make sure that they are intact and there is no obvious physical damage.
Reboot both devices
If there is no Wi-Fi on the receiver only you have to restart it. To perform the task it is enough to switch it off and then on again. If even after disconnection the TV receiver remains connected to the grid, the plug of the device is pulled out of the socket.
Router can be rebooted in the same way. Before reactivating it, you need to wait about a minute until the Internet session is over. Connection will be automatically reset and equipment will turn on with updated settings.
Change the location of the router
The problem of an unstable signal can be solved by moving the equipment closer to the receiver.
In order for the two devices to easily detect each other, there must be no obstacles between them:
- Household appliances operating on a similar frequency;
- metal objects;
- mirrors in the signal path;
- indoor flowers and plants.
Walls are also difficult for radio signals to get through. To improve its performance and increase the speed mode, you need to install the device as high as possible: mount it on the wall or put it on the cabinet.
Eliminate DNS server errors
The last step is more often used on Samsung corporation models. When the firm’s servers are overloaded, it starts to have problems with the clear network radio signal. To connect to the World Wide Web directly, bypassing the infrastructure of the manufacturer, use the free DNS from Yandex or Google.
Why the TV does not connect to Wi-Fi and what to do?
Modern technology does not stand still. Today everyone has an opportunity to buy a TV set with Smart TV function. Such a device not only allows you to watch TV, but also expands other features.
- social services;
- message exchange;
- visits to various sites;
- listening to music;
- Viewing downloaded movies.
The most common way to connect TV equipment to the Internet is a wireless connection, also known as a Wi-Fi module. However, in the process of operation, there are often failures, errors, and the signal at some point disappears. It is worth to understand in detail why the TV set can no longer connect to Wi-Fi, and what to do in this situation.
Problems with Wi-Fi on LG Smart TV: can’t see Wi-Fi network, can’t connect, internet not working, network error 106, 105
To the article, in which I showed you how to connect LG Smart TV to a Wi-Fi network, more than eight hundred Комментарии и мнения владельцев have been left so far. These are mostly questions that have to do with all sorts of issues that arise when connecting LG TVs to a Wi-Fi network. The most popular problem. when the TV does not see the Wi-Fi network, or does not connect to the wireless network. And of course, after connecting to Wi-Fi, the Internet very often simply does not work. In the settings the connection scheme is displayed, and there is a connection between the TV and the router (gateway), but there is no connection to the DNS and therefore to the Internet.
In the settings of LG Smart TV there is an error “No connection to Internet via Wi-Fi. Internet does not work in your browser or TV application. Can’t watch video on YouTube app. Error “connect to network (-105). Cannot find requested address. Check network connection”, or error 106: “Network not connected. Check the network connection status”. Also there are often problems with connection to wireless networks at 5 GHz frequency. Even when your TV supports the 5 GHz band (802 standard).11ac). Many TV sets have no built-in Wi-Fi receiver at all. They can not connect to wireless networks, or only after connecting a proprietary USB receiver (Wi-Fi hardware dongle).
In this article we will talk about solving problems with Wi-Fi connection on LG TVs with Smart TV system webOS. Which has long been installed on all new TVs of this manufacturer. Personally, I think it’s the most convenient, beautiful, fastest and functional platform of all that is now on the market. I think that solutions from this article can also be applied to LG televisions that run on the old Smart TV system.
How to update the firmware
Perhaps the software of your TV is outdated, which often causes problems with the connection to the wireless network. In this case you need to update the firmware. You can do it over the Internet, connecting via a network cable, or download the firmware from an external storage device, such as a disc or flash drive. Depending on the manufacturer, there are different ways to update the firmware.
The software update guide for these devices looks like this:
- Go to settings and select the section ” Support “.
- Find ” Software Update ” and click the line ” Update Now “.
- The device will connect to the manufacturer’s server and check if the new firmware is available.
- If a new firmware version is found, the TV will ask you to confirm the firmware.
- After installing the new software, you need to reboot the device.
To update the firmware proceed as follows:
- Go to the manufacturer’s official website and search for your device model.
- Find “Support” and select the “Drivers, Firmware and Software” tab.
- A list of firmware will open, among which you need to choose the newest one and download it to your PC.
- Upload the firmware to a new folder and then copy this folder to a flash drive.
- Then insert the flash drive into the USB slot and wait until the device sees the firmware offered.
- The system will start the software update process and will ask you to confirm the operation.
Any other TV
On devices from other manufacturers (Sony, Philips, etc.).e) The process of updating is not essentially different from the previous ones. Here’s how to proceed:
- Go to the official web-site of the manufacturer and download the new firmware for your model.
- The flash drive must first be formatted in the FAT32 system and then the downloaded file must be dropped there.
- Click on “Extract” to extract the file.
- After unzipping, remove the USB flash drive from your computer and plug it into a USB port on your TV.
- Go to settings and select “Support”.
- Find “Software Update” and press the “Update Now” line.
- The system prompts you and you need to confirm it.
- The device will search for the firmware file on the flash drive, once found it will display: “Update”, which should also be pressed.
The updating process will start, after which the TV should automatically reboot.
The TV set is not connected to the Wi-Fi router
TVs have long ceased to be solely a means of reception and playback of television signals. Modern models have a number of additional useful options that allow you to expand the functionality of your multimedia device. Among them, a special place belongs to the possibility of access to the Internet. Thanks to which the receiver is no longer the usual electronic equipment, capable of playing back on the screen only transmitted images with the use of loudspeakers. Such advanced units are called Smart TV or “smart TVs.
You can connect to the World Wide Web in two ways: via LAN cable or via Wi-Fi. The first one is considered less attractive and insecure.к. Involves a lot of wires that need to be hidden somewhere. And it does not look very aesthetically pleasing in terms of space ergonomics.
The optimal variant is to use a wireless network. The latest TV models come with this function by default, so it is in high demand among buyers. However, statistically, mishaps happen with these samples as well. The TV does not connect to the Internet. the main problem faced by the happy owners of “smart equipment”. There is a reasonable question: “Why can’t the TV connect to the Wi-Fi router??” To find the answer, you must deal with the cause and troubleshoot. You can do it yourself. How, read the article.
Buffering of connection
Streaming content for your TV may need more bandwidth for a good high-resolution transmission. If several devices are using this network at the same time, it can increase the bandwidth and cause buffering problems. Depending on the type of Internet connection and provider’s capabilities, users can often get slower transfer speeds during peak hours, which also causes buffering failures. Updating the user Internet plan with more bandwidth can solve the network congestion errors.
There are several factors that can also cause WI-FI signal failure:
- Distance from the router to the TV. If it is too large, the signal will be weak, interruption of the streaming video will be a frequent occurrence in the house, especially during peak hours. To avoid it is necessary to move the TV or router positions closer to each other. If their positions can’t be changed, then a Wi-Fi extender would be a good option to extend the range of your wireless network.
- It is not recommended to install the router close to any devices that generate large magnetic fields, such as a microwave oven. This will cause signal loss.
- If there are too many devices connected to the Wi-Fi network, it can cause congestion problems. You need to limit the number of receivers, or disable those not in use, to free up bandwidth in your Wi-Fi network.
- If you can run an Ethernet cable between your router and your TV, it is recommended that you do so. It will be faster and more stable than Wi-Fi.
TV sees Wi-Fi, but can’t connect
Another common problem is that the device detects the network, but throws an error when you try to connect. If this problem occurs, this is already a good thing, as it is much easier to solve than if the TV did not see the network at all. Usually the device gives an error “Connection error” or “Incorrect/Invalid password”. Users often forget network password and use automatic connection or share network with QR code.
The password from the network can be viewed in the settings of your PC, connected to this Wi-Fi, or in the settings of the router. As for the network key, it is registered on the router itself, as a rule, on its lower part. Most often, the TV asks for the exact numbers that are registered in the router. The network key can also be changed during operation, users often forget the key set. Therefore, the best way to connect is as follows:
- Reset the router to its factory settings. You need to press and hold the “RST” (“Reset”) button on the router for 10 seconds, until all the signal LEDs start flashing.
- Refresh the search window of the available Wi-Fi networks on your TV.
- Make the connection.
- In the window “Password”, specify the network key prescribed in the router.
After that the connection is always successful. In some cases there may be no internet connection, but the connection to the LAN network will be made.
How to connect to Wi-Fi?
In order for TV to work with existing router its settings must be configured correctly. If we talk about the wired connection to the router, then we must check the accuracy of the IP-address, default gateway, DNS-server and subnet mask (or automatically set them). When connecting wirelessly, in addition to the above parameters, you must make sure that there is a connection to the Wi-Fi network, which requires a password.
All Samsung Smart-TV modifications have the same settings. Only the order of entering the necessary settings in the menu differs. Let’s look at some examples.
Setting up connection to Smart-TV
Let’s take Samsung K-Series receiver as an example. To set up wireless connection in auto mode there’s no need to enter IP-address and other parameters of the network, you just need to do a few actions.
- Enter the settings menu via the remote control or the buttons on the TV.
- Open the “Network” tab on the left side of the settings menu.
- Select “Network Setup” in the box that opens.
- If it is set that the TV is connected to the network via a network cable, select “Cable” in the dropdown menu “Choose network type”, then the setting is complete. If the wireless connection is used, it is selected as “Wireless.
- It will take some time for the receiver to scan for available wireless networks. After scanning is complete, available Wi-Fi networks will appear on the TV screen. Choose your network.
- If the receiver has not been connected to a Wi-Fi network before, you will need to enter it on the next page of the connection settings.
- Check the box next to “Show Password” to make sure that you do not mess up the password for the Wi-Fi network.
- If the password is correct and the TV and/or the router are working properly, you will see a message on the TV screen saying that it is successfully connected to the Wi-Fi network.
- An icon in the upper area of the screen will indicate that there is a connection to the network. If there is a connecting line (orange dots) between the icon with the planet and the router icon, it means that the TV has network access. The configuration is complete.
How to Fix All Wi Fi Problem for Android Smart TV (Not Connected, No Internet, Authentication)
Autosetup is possible only if a DHCP server is connected to the router (an option that allows you to connect to the Internet without having to manually enter the network settings).
If the DHCP server is not enabled, you can activate it by reconfiguring your router. It is possible to correct the situation by tuning TV-receiver network parameters in manual mode.
Let’s study an example of Wi-Fi connection settings on Samsung Smart-TV UE-series.
- Open the settings menu of the receiver, go to the “Network” tab, then select the “Network Setup” section.
- Select “Next” in the next window.
- If the TV is connected to the internet via cable, you need to select “Cable” from the “Choose Network Connection Type” list. If the connection is made by Wi-Fi, select “Wireless. (general), then click on the “Next” button.
- On the screen you will see a list of available networks. Select your.
- In the next window, enter the password from the Wi-Fi network, click “Next” to connect.
- If the receiver receives the network parameters from the router, you will see a window with the information.
- If in the fields “IP-address”, “Subnet Mask”, “Gateway” and “DNS Server” are entered values, simply click on the “Next” button to complete the connection settings. If this is not the case, click the “IP settings” button to manually enter the appropriate network parameters.
- In the next window in the menu “IP Mode” select “Manual”. Fields with network parameters will appear on the TV screen.
- All fields should be filled in according to the settings of the router. They can be seen, for example, in the properties of the network connection on your PC or smartphone connected to the same router. Make the same settings in the TV receiver, except for the IP address (the last number in it must be changed).
