Why Samsung Wont Connect To Wifi

Replacing the WiFi adapter with an external one

This method will not correct the problem 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 WiFi adapter resembles a regular USB flash drive. Like most other devices, it works when connected to a TV via USB.

There is one more type of adapters for WiFi reception on sale. They have an external multi-directional antenna, which 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.

Why Samsung Wont Connect To Wifi

Using a different WiFi connection method

If you established the connection by manually entering the wireless password, try connecting via WPS. Wifi 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 WiFi 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.

Changing the location of the router

Problems in the operation of the wireless network on the TV may be associated with 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. Major Signal Obstacles Walls, Furniture and Working Appliances.

Installing an access point on an elevated level will help ensure better WiFi connectivity. 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.

Reset TV settings

A quick way that in some cases helps to solve problems with WiFi on Smart TV is restoring 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 information recorded. Menu path for restoring factory settings on popular TV models:

  • Lg: Settings. Additionally. General. Factory reset.
  • Samsung: Support. Self-diagnosis. Reset.
  • Panasonic: Settings. System menu. Initial settings.

Manually specifying connection data

Using the built-in Smart TV menu, navigate to the WiFi 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 255.255.255.0. In the Gateway line, enter the IP address of the router, which is used to enter the settings.

Finding problems with a WiFi router

Difficulty connecting to a wireless network may be caused by incorrect router settings. 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.

Check the Security tab in your 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, connections of devices from this list will not be blocked, so normal WiFi operation on the TV will be restored.

Smart TV MAC address 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.

Why Laptop Can’t See Wi-Fi Typical Causes of Wi-Fi Connection Problems

Portable devices such as a laptop, today are closely related to the life of any modern person, being an indispensable tool for processing information of any nature. One of the main advantages of this type of computer, in addition to its mobility, is the ability to connect to the Internet or other local network devices (printers, other computers, file storages, etc.), regardless of whether the user is at home, in an office, in a hotel, airport, cafe or even a park. Such capabilities are made available thanks to the built-in wireless LAN adapter using Wi-Fi technology.

Problems with connecting to Wi-Fi can cause serious inconvenience to the user when using a laptop, greatly reducing its consumer qualities. The most common reasons include:

  • Errors in the operation of network services of the Windows operating system;
  • Incorrect operation of the Wi-Fi adapter of the computer due to its malfunction or incorrect functioning of the device driver;
  • Changed (for example, by the network administrator) or incorrectly entered credentials to access a specific Wi-Fi network;
  • Malfunction or incorrect settings of the Wi-Fi network router;
  • Considerable distance from the Wi-Fi router or / and location near source of strong electromagnetic interference.

Let’s consider in more detail the most common situations, as well as ways to eliminate them.

The laptop does not connect to wifi although wi-fi sees

If the laptop does not connect to the wifi laptop, but Wi-Fi sees, then to solve the problem, you need to do the following steps, described in detail in the article.

What to do if the laptop does not connect to wifi

If the laptop does not connect to wifi, then the first thing to do is restart the operating system. In view of the presence of many Windows system services, on which the correct operation of the wireless network depends, under a certain set of circumstances (enabled automatic updating of device drivers, operating system, utilities preinstalled by the laptop manufacturer, as well as other application software), a situation may arise in which a restart your computer is really capable of fixing the problem.

The second step to be done is to check the availability of the wireless network that you want to access. This can be done by viewing the list of broadcasting wireless networks from a mobile phone equipped with a Wi-Fi module, or in the list of wireless networks displayed by Windows, for which you need to search for available wireless networks.

In the event that the desired name of the wireless point is absent, or the connection to it is unstable (there is no access to the Internet), one of the reasons may be a malfunction of the router itself, whose task is to create a wireless network with routing of connected devices in the right direction. As in the first example, sometimes it is possible to fix the situation by rebooting the router. As a result of power outages, overheating or overloading of the device itself, it is possible that some internal processes loop and, as a result, its improper functioning. The variant of a malfunction of the Wi-Fi router is more likely if several clients connected to it have connection problems at the same time.

With normal operation of other computers in the same wireless local area network, we will consider a number of measures to find out the reason why the laptop does not connect to wifi.

Checking the Wi-Fi module of the laptop

Incorrect operation of the built-in wireless adapter can be one of the reasons why the laptop does not see the wifi network. The correct operation of the Wi-Fi module can be checked in the Network adapters section located in the Device Manager of the operating system, to access which there are several ways:

  • Open the properties dialog My Computer (This PC) with the Windows Pause \ Break key combination and go to the Hardware section. Device Manager or go directly to the corresponding link (on Windows 10);
  • By calling the Device Manager snap-in with the Run utility (Windows R) in the line of which you need to type the process name devmgmt.Msc and click OK.

In the Device Manager window that opens, you need to make sure that there are no problems with the Wi-Fi module, its direct presence in the Network adapters group, and also that there are no system warnings (exclamation or question marks).

If the name of the Wi-Fi adapter is displayed correctly, it is possible to assume that the module is working properly, and the reason that the laptop does not see the wifi network is likely to be incorrect connection settings. Otherwise, to fix the problem, you may need to check the network adapter drivers.

Driver check

The Wi-Fi module driver is also checked in the Device Manager snap-in, where in the Network adapters group you need to select the properties of the wireless adapter. In the Wi-Fi adapter dialog box, you need to check the following points:

  • System messages in the Device Status section of the General tab make sure that the device is recognized and is working normally;
  • Check the Events tab for system messages about device operation;
  • Make sure that all fields on the Driver tab are filled in correctly (there are no entries No data, Unknown supplier, etc.).

To exclude incorrect operation of the adapter, due to the device driver, it is advisable to reinstall it, after downloading the most recent version of the software from the laptop manufacturer’s website. Before reinstalling or updating the driver, you must first remove the device from the system by clicking on the Remove button on the Driver tab, and then run the updated driver version downloaded from the manufacturer’s website. As a rule, it has its own installer, which will perform all further necessary installation procedures on its own.

Setting connection parameters

Incorrect connection parameters can also be the reason why the laptop does not see Wi-Fi. The configuration procedure is performed in the Network and Internet section located in the Control Panel. To configure Wi-Fi, in this section, select the Connect to a network link and select the required network and click the Connect button. It should be noted that to connect to a Wi-Fi network, you need to know its full name and access key (password). Upon successful completion of the sounded procedure, a working and configured router, the connected workstation should already have access to the Internet.

If the tasks of connecting to a Wi-Fi network include the need to manage shared access to files, folders and printers from other computers on the local network, then the next step after successful authorization in the Wi-Fi network is to configure the Homegroup. This snap-in will allow you to make the required settings for sharing both files and folders, and other devices (printers, scanners, etc.).

Password check

You can check the password and change it, if necessary, in the Network and Internet section located in the Control Panel, where you need to click on the Network and Sharing Center link and select the property of the required connection. To view the account information in the opened dialog box of the network connection status, click on the Wireless network properties button. Password verification is available on the Security tab. By default, the password is displayed with hidden characters, which can be seen by setting the checkbox opposite the line to display the entered characters.

Mac filter settings

One of the reasons why the laptop does not connect to wifi may be the security setting of the router, namely the set permissions of the MAC filter. The MAC filter is configured directly in the section dedicated to the security of the wireless network located in the settings of the router itself. To allow a laptop to use a Wi-Fi network through a router, an entry must be present in the security settings of the router for connecting the physical address of the network card of this device.

Setting up a router

You can access the settings of the router by going to its IP address. The exact IP address of the router, as well as the login and password for accessing its settings, can usually be found by the sticker on the back of the device (provided that the accounts have not been changed by the user). Upon successful authorization on the router, to facilitate its correct configuration, most devices provide for the use of the Assistant, which allows you to step by step configure the network in such a way as to ensure the desired operation of all connected devices at the proper level in the shortest possible time. It is advisable to make finer settings for the router only after reading the operating manual for the router posted on the manufacturer’s website.

It should be noted that it is advisable to configure the router using a wired connection to it (most routers are equipped with a specially made crossover network cable).

Doesn’t connect to wifi on windows 10 laptop

If the laptop does not connect to the wifi network and the user has taken the above recommendations, then it will not be superfluous to try resetting the TCP / IP protocol parameters manually, for which it is necessary:

Open the Command Prompt as administrator (from the Start menu, Windows System section in the properties of the Command Prompt item, select Run as administrator);

At the command prompt of the window that opens, enter the command: netsh int ip reset c: \ resetlog.Txt
to restart a computer.

It is worth noting that Microsoft has also created a specialized utility for the convenience of users (available at: https://support.Microsoft.com/ru-ru/help/299357/how-to-reset-tcp-ip-by-using- the-netshell-utility in the Easy Fix section) to interactively perform the above TCP / IP reset procedure.

Also, in some situations, updating the IP address received from the router can help correct the situation with connection errors. To do this, enter the following two commands in turn at the command line prompt:

  • Ipconfig / release
  • Ipconfig / renew

This command will force the update of the IP addresses of all network adapters installed in the system.

Doesn’t connect to wifi on windows 7 laptop

Finding the reasons why the laptop does not see Wi-Fi with Windows 7 installed is practically no different from the recommendations given for Windows 10. A feature may be the presence of warnings issued by the User Account Control (UAC) component. For successful completion of the procedures, it is necessary to allow the actions performed in the above recommendations.

Another method that can help in solving the problem is to create another Wi-Fi hotspot on a laptop.

The easiest way to create a software access point is to use the command line, at the prompt of which it is enough to enter the following commands one by one:

  • Netsh wlan set hostednetwork mode = allow ssid =”Name of the access point to create” key =”Access password for the created access point” keyUsage = persistent
  • Netsh wlan start hostednetwork

This procedure creates a virtual Wi-Fi access point (Virtual WiFi), access to which is allowed to all other devices. This will check the serviceability and correct operation of the adapter installed in the laptop.

If you need to turn off Virtual WiFi, just enter the following command in the command line: netsh wlan stop hostednetwork

Why the TV does not see the router (does not connect to Wi-Fi)?

Very often, people who have bought a new TV for themselves face such a problem when trying to set up the Internet on it, he does not see the router, or he sees but does not connect to wi-fi. There can be many reasons for this, so it makes no sense to list them all. For this reason, we will look at the most common ones.

  • First you need to determine if your TV directly sees any wi-fi device (for example, a smartphone) on which the software is installed. This will give you the ability to determine if wi-fi works at all on your TV.
  • The TV does not have automatic network detection enabled. In order for the TV to see the router, you must enable this function in the menu. After that, the TV will start searching for available routers in automatic mode.
  • The TV does not see the router even when network detection is on. Perhaps the reason for this lies in the router itself. Try to properly configure the router by contacting your Internet provider.
  • The router works fine, the Internet is available on other devices, but the TV still does not see it. In this case, you should start looking for the problem in the TV itself. To do this, disable DHCP on the router for a while. The TV itself has network settings that must be specified in accordance with the parameters of the router. For example, if the gateway address of the router is standard 192.168.1.1, then on the TV we indicate the following parameters:

Ip address 192.168.1.2
Subnet mask 255.255.255.0
Gateway 192.168.1.1

In most cases, with these settings, the TVs begin to see the router and connect to the Internet via wi-fi.

  • Your TV model may not support Wi-Fi network connectivity. In this case, you can solve the problem by additionally purchasing a special wi-fi adapter. Please note that there are a lot of adapters, and not all of them will be able to fit your specific TV model. Therefore, before purchasing, consult a specialist.
  • If you’ve just set up a wireless connection and the TV still can’t see the router, try restarting the router and turning the TV off and on. This in some cases helps devices see each other.
  • Everything is set up correctly on the TV, the router has Internet, but the TV does not see it. In this case, you should start looking for the problem in the router itself. The fact is that there are very few network settings on the TV, but there are plenty of them in the router. Contact your provider and clarify what exactly needs to be changed in the router settings.

If you tried all of the above and nothing helped, then we recommend that you contact the TV Service Center to specialists in the repair and setup of TVs. Only they will be able to determine exactly what is the real reason that your TV does not see the router and does not connect to wi-fi. Timely contacting our masters will allow you to avoid many problems in the future, since self-changing some of the TV’s settings may even lead to its breakdown. In addition, it is very convenient to contact TV masters, since you do not have to take your TV anywhere, and experienced specialists will carry out full diagnostics and eliminate all problems right at your home.

Checking Router Settings

An error connecting the phone to a wireless WiFi network, often occurs due to incorrect router settings. The fact is that modern Wi-Fi routers support DHCP technology. This means that all data on the connection of the router is automatically sent to the phone. This is exactly what smartphones and tablets are focused on. If you disable this function, then the phone will not be able to obtain an IP address, and, accordingly, connect to the network.

The solution to the problem is to enable this feature if it is disabled. To do this, go back to the router settings and open the advanced settings. Now we are interested in a window called Network. In it, go to the LAN section. These are local network settings.

This is where you can turn DHCP on or off. It should be noted that to enable the function, the Mode line should be set to Allow. Below is the range of IP addresses, you can also change it. After enabling the DHCP function, apply the parameters and save the changes. It is also recommended to reboot the router. After that, try to connect your phone again.

Why the smartphone does not see the Wi-Fi network: Why won’t my phone connect to a Wi-Fi hotspot

The phone won’t connect to the WiFi hotspot, this is a common mistake these days. The fact is that smartphones with a built-in Wi-Fi adapter have already become part of people’s lives, and almost everyone already has such a device. Smartphones have gained such distribution due to their undeniable qualities. After all, they allow you to use the Internet and solve problems no worse than a computer, but at the same time are mobile and compact.

Unfortunately, although in most cases the connection to the WiFi network goes through without problems by pressing just one button, sometimes there are still various errors that not every user can solve on their own. That is why in this article we will look at why the phone does not connect to the home WiFi network, as well as how to fix this error.

Reasons why the phone does not connect to the WiFi network

We will analyze the most common problems, and also consider how to solve them. Their list includes the following:

  • Incorrectly entered security key.
  • Incorrect Wi-Fi router settings.
  • Router malfunctions (freeze).
  • Android platform crash (rare, but still occurs).

So, let’s look at all these errors in more detail.

How to connect to WiFi router in Windows 8 :. Wifi router malfunctioning

Another reason why the phone sees a WiFi network, but does not connect to it, is that the device simply hangs. In this case, for example, a laptop can work normally and access the Internet. The fact is that, speaking of freezing, one should understand crashes and stoppages of some functions. For example, DHCP may stop working due to overload or power outages. At the same time, devices that were connected to the access point earlier have already received an IP address and can work normally. Other functions of the Wi-Fi router may also stop working.

The solution to this problem is to simply reboot the device. And for this you don’t even need to go into the parameters. It is enough to turn off the power supply of the router from the outlet for 7-10 minutes. After that, enable it and wait for the download. Try connecting again from your phone. Such freezes can occur not only on budget models of routers. The only difference is in the frequency of such errors.

If you have completed all the above steps, but the error of connecting the Wi-Fi network on the phone remains, then it is quite possible that the failure occurred in the smartphone itself. The fact is that mobile devices use conventional wireless adapters, which can also freeze or malfunction. But unlike a computer, there are no advanced settings on the Android platform. On such platforms, all parameters are entered initially, and there is no way to change them. This means that you can solve this problem in the same way as in the previous case, just restart the device.

Now you know the most common reasons why your phone’s WiFi won’t connect. As mentioned above, there may be other connection problems, but solving them requires an individual approach.

You can read more about solving problems connecting your phone to a WiFi network in the following article.
