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.

This problem is one of the most serious, we will not be able to connect to the Wi-Fi network and therefore we will not have access to the Internet except through mobile data. In other cases Wi-Fi network is disconnected from Samsung mobile. The problem that is closely related.
Clear all WI-FI data
The first thing we should do, and this is in most cases the ideal solution. Is to erase all data from the Wi-Fi network. Samsung cell phones include an option to make the process easier, forcing us to perform the following steps and we can immediately return to browsing without problems after restoring the network:
Disable GPS Accuracy Increase
Failures when connecting to WI-FI can be related to GPS, as we have among the One User Interface options to improve the location, relying on this connection. To check this ourselves, we just need to go into Settings Location Method Phone Only Improve Accuracy Disable Search with WI-FI. After disconnecting, we will check if that was part of the problem.
Analyze WI-FI problems on Samsung
Samsung cell phones combine great intelligence based on components and software that we can use at this time to find Samsung Wi-Fi glitches. We only need to open the Samsung Members application, which is available on all cell phones, and we will be able to test its sections at once.

Why is the Wi-Fi not connecting on your phone?
Often, after a long time, the router will connect, then disconnect. Phone can switch to mobile network by itself.
Why Wi-Fi isn’t connecting on your phone:
- 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
In some situations, TV set doesn‘t connect to the Internet via Wi-Fi due to incorrect router settings. To configure the device, open the control panel. To do this, enter the appropriate combination of numbers in the address bar of your browser. For details on how to open the main menu of your router, please refer to the user manual.
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? In the future, devices added to this list will not be blocked. Therefore, communication through the router will be correct.
How to know the MAC-address of your TV? All the information you need is displayed in the settings. The exact path varies depending on the equipment manufacturer. Let’s look at a few of the most popular options:
- Samsung: Go to settings, then to “Support” and select “Contact Samsung”. Click on the down arrow and then select “Wireless MAC Address.
- LG: Open the settings and go to “Support”. Open the “Product Info” tab. This is where the MAC address will be.
- Philips: Go to settings and select “Setup. Then you need to select “Manual Network Setup”. You need the “View Network Settings” command.
If you change the router’s network settings or add the TV’s MAC address to the “white list,” reboot the router for the changes to take effect. Reboot from the “System” tab. Alternatively, press and hold the router’s power button.
If you have tried to connect your TV to your home wireless network by entering the password manually, then it also makes sense to try another way of setting up the Internet connection. WPS. Wi-Fi Protected Setup technology. allows you to quickly set up the Internet on your TV. But this mode must also be enabled on your router. You can do it via the system settings or by clicking on the appropriate button. It is located on the router.

What to do if the WPS mode worked correctly before, but later the TV stopped connecting to your home network? Enter all the necessary information manually. To connect to the hidden point, you must enter not only the security password, but also the name of the network. SSID. Televisions with older OS versions far from always support scanning for hidden wireless networks. Therefore, before updating the software, remove the hidden network names in the router settings.
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.
Firmware the TV
