Samsung doesn’t connect to Wi-Fi

My phone can’t connect to Wi-Fi: Causes and solutions [Android]

Nowadays, Wi-Fi networks cover almost everything and everywhere: houses, parks, airports, hotels, etc.д. And while mobile internet is still not cheap and available enough, somehow you have to connect to these Wi-Fi networks when using your phone.

The fly in the ointment is that about every 10th connection from the phone fails.

In fact, that’s why I decided to “focus” the topic of today’s article on this problem (especially since there are a lot of questions about it). I would like to point out that in this article I will refer to those devices that run on Android (Android).


By the way, a lot of people complain about the too short battery life of the phone.

If you want to know what can cause the rapid battery drain, to eliminate these causes and increase battery life of your smartphone, I recommend this post

Checking the functionality of the built-in Wi-Fi module.

As cliché as it sounds, the first thing you should do is to make sure that your TV model has a built-in Wi-Fi module. If it is not, you can purchase an external Wi-Fi adapter that is compatible with your model. Assuming that your phone has Wi-Fi support, you need to check whether the wireless module is working.

Go to “Menu”. “Support”. “Contact Samsung” on your TV and scroll down a few pages. If you see just zeros, dashes or other monotonous values in the MAC-address line (unique ID), then the built-in WI-Fi module of your TV is not working. Usually manufacturers provide two MAC addresses on this page. One for wireless and one for wired. Also you can see the MAC-address value at the following address: “Menu”. “Network”. “Network status”.

Depending on the connection to be created (wired or wireless) the MAC-address will be automatically substituted for the chosen mode. To definitively check if the Wi-Fi module is working or broken, make a direct connection. To do this, you can take a smartphone and turn on the access point in it, and then try to connect to the mobile Internet from your TV. If the Wi-Fi connection or network fails, contact a specialist workshop for a replacement, or contact a Samsung Cyber Service Center.

If the mobile connection took place, then make sure in the stability and quality of the wireless signal from the Wi-Fi router and, if necessary, switch to another channel. What affects signal quality, read here, and how to diagnose your Wi-Fi network and choose a less congested one in an earlier article. You can just experiment with “Auto” mode and channel 11 and boom change the frequency from 2.4 to 5 or vice versa.

Try to create a wireless connection automatically. To do this you need to activate the DHCP-server function in your Wi-Fi router and try to create a connection from your TV automatically. Here is how to get into the interface of your network device.

Some Internet Service Providers may block the IP addresses of Samsung servers. Contact your service provider and ask him about these things. If everything is OK and there is no blockage, then move on.

Try to reset the network settings of the wireless router, and if there is new official firmware, be sure to update it. In our previous posts I wrote about how to flash TP-Link and Asus router. By the way, if you’re using a Wi-Fi router that your ISP company kindly gave you with its network settings coded in, even after updating the firmware on it, the TV may not connect to it.

  • Long distance from the router and small range. In that case, go to the settings, and increase the range of the device.
  • The frequency on which there are a large number of networks. Most often we purchase a router that operates at a frequency of 2.5 MHz. If you enable wi-fi search. The number of devices will be displayed. They clog each other’s work, because of being on the same frequency. In this case rebooting, firmware, change of channel may not give any results. The only effective option will be the purchase of a new router which works on a frequency of 5 MHz.
  • Channel congestion. Look in the settings of the router, on which channel it works. It is usually recommended to set a certain channel in the same models. As a result, on the same channel will be observed overload, a large number of devices. Having changed the channel, you can considerably improve the situation.

Improperly configured router

To change the TP-Link router settings, go to “DHCP. Check if the DHCP server is activated and functioning correctly. If this option is deactivated before, the TV and other devices connected to your home network will not have an IP address automatically assigned. You can’t get quality routing without automatic IP configuration.

Go to “Security” in the router settings. Turn off customer MAC filtering if it’s been enabled by default. On Asus, D-Link, TP-Link, Huawei routers and devices from many other manufacturers you can put the MAC-address of a device into a “white list. What it does?

Why Samsung doesn’t connect to Wi-Fi

There can be several visible reasons for a connection error. often than not, problems arise from the router side or internal network settings. Before looking for the causes of the lack of connectivity, you need to do some superficial diagnostics:

  • Make sure the network you are looking for even exists. Often users try to connect the TV to a network that doesn‘t exist. You can use any other device with Wi-Fi: a phone, a laptop, or a tablet to check network availability. Make sure that the other devices can see the network, and successfully connect to it.
  • Can the TV connect to other networks. If the problem lies in the network settings, then connecting the TV to other networks will not cause any problems. If the TV sees all networks, but cannot connect to any of them, you will need to change the TV settings.

If your Samsung TV does not connect to the internet, but you have successfully connected to a wireless network, it is recommended to reboot the router and turn off the TV for 10-15 minutes. Then you will need to reconnect, and in most cases the problem will go away. If the TV still won’t connect to the internet, you’ll need to diagnose and fix the problem.

Now you know what to do if your Samsung TV has lost Wi-Fi. If the TV-device has stopped catching the signal or the speed of Internet is very slow, use one of the listed ways of solving the problem.

If you connected an external Wi-Fi adapter, but the TV set can’t see the device, this indicates the presence of compatibility problems. To avoid such difficulties, buy only brand-name devices. It is desirable to buy a device from the same company as the TV.
