Wi-Fi problem Samsung Galaxy A42
All the news on Samsung Galaxy A42 in our articles.
It is very convenient to use Wi-Fi via your Samsung Galaxy A42, especially in public areas or inside the house.
But it is not uncommon that your Samsung Galaxy A42 can no longer connect to the Wi-Fi network. We will see in detail how to solve this problem.
Firstly, the simplest solution is to use an automatic Wi-Fi application as offered on the Play Store. In particular, we recommend WiFi auto connect, Wi-Fi Fixer and Cleaner and WiFi Doctor.
Wi-Fi is all the more practical since it does not overload your data consumption on your Samsung Galaxy A42: your telephone operator, 4G or 5G, does not generally charge for Wi-Fi as for mobile data.
In addition, many places do not hesitate to offer relatively fast Wi-Fi networks.
Therefore, it is not uncommon to prefer to connect your Samsung Galaxy A42 to Wi-Fi rather than using 4G or 5G cellular data service.

Not being able to connect to Wi-Fi with your Samsung Galaxy A42 is certainly not pleasant: we often rely on Wi-Fi networks for data-intensive needs, such as streaming video playback or online games.
Wi-Fi is particularly useful for using social networks such as Facebook, WhatsApp, Snapchat, Instagram or TikTok.
So let’s see how to solve this Wi-Fi failure on your Samsung Galaxy A42.
First, don’t hesitate to have a look at the Google Wi-Fi troubleshooting help, which often proves to be very useful.
Setting the date and time on your Samsung Galaxy A42
This may seem benign, but one of the first things to do is to check if the date and time are up to date. If the date and time do not match the outside time then you need to adjust these settings.
Indeed, for security reasons, many Wi-Fi networks will not give you access if the date and time are not correct on your Samsung Galaxy A42.
Open the “Settings” menu, then “Additional Settings” and then “Date and Time”. From there you can set the date and time on your Samsung Galaxy A42.
It is best to choose the automatic setting so that this parameter will lock to your operator’s network.
Next, remember to clear the Wi-Fi cache on your Samsung Galaxy A42.
To do this, go to “Settings”, then “Additional Settings” and “Application Management”. Then search for “Wi-Fi Settings” and then tap “Clear Cache”.
Repair your network with the Wi-Fi Doctor application
Wi-Fi Doctor is a free Android application that can be used to analyze and repair Wi-Fi networks, especially when the signal is too weak.
This application will help you to make the Wi-Fi network stronger, so that they can be used on your Samsung Galaxy A42 to access the Internet.
You can download the Wi-Fi Doctor application for free via the Google Play Store. Also two very useful applications to unlock Wi-Fi on your Samsung Galaxy A42 are Wi-Fi Fixer and Cleaner and WiFi Fixer.
Restart the device or router
If the above method does not work and you are connected to a public Wi-Fi network, try restarting your device.
For those of you using your own network, this method also applies to routers.
So don’t hesitate to restart your Box or modem to reset the Wi-Fi.
Although it sounds simple, this method is powerful enough to solve Wi-Fi problems.
Then try to reconnect with your Samsung Galaxy A42 to try to get an internet connection.
Wi-Fi too slow on Samsung Galaxy A42
Too slow Wi-Fi occurs mainly on campus or in public spaces with many users.
The total bandwidth being limited, the number of users ends up making Wi-Fi very slow for your Samsung Galaxy A42.
In some cases, the bandwidth per device is itself limited: your Samsung Galaxy A42 can then have access and not interfere with other devices. As a user, you can only ask the campus or the owner to improve the service and quality of the Wi-Fi zone.
Another possibility for which Wi-Fi cannot be connected is that the maximum number of users (number of IP addresses) has a limit on the network. The number of users may have reached this limit and new devices, such as your Samsung Galaxy A42, cannot connect.
Specifically, a Wi-Fi service on a campus or café typically provides an IP address limit of up to 200. Once this limit is reached, other users cannot connect.
To be able to log in, you have to wait for other users to log out of the service.
This means waiting for an IP address to become available.
Only in this case you will be able to connect your Samsung Galaxy A42 to the network.
In this kind of case, you as a user of the service can do nothing: just wait for an IP to be released.
Check the network connection on your Samsung Galaxy A42
One of the first steps to spot problems with a Wi-Fi connection is to make sure the feature is active.
It is quite common to forget to turn Wi-Fi on or off as needed.
Enabling Wi-Fi on your Samsung Galaxy A42 is quite simple: just slide your finger from the top to the bottom of the screen and press the Wi-Fi symbol.
Another parameter that should be deactivated is the aircraft mode.
When this feature is active, Wi-Fi will be automatically turned off.
With this option, all Internet connections are turned off.
So you need to disable the airplane mode on your Samsung Galaxy A42.
These two methods are the most basic steps in troubleshooting a device that does not connect.
If both methods did not work on your Samsung Galaxy A42, you can try the following methods.
Check for forgotten networks on your Samsung Galaxy A42
The Forget Network feature is designed to eliminate Wi-Fi on your Samsung Galaxy A42.
This may interfere with your device’s access to Wi-Fi.
To resolve this, try to delete the network you want to connect to.
After that, you can try to reconnect.
To do so, simply press the network you wish to delete and select “Forget”. If you plan to reconnect via the network, you will have to start over again.
This includes re-entering the required password.
Make sure the router name and password are correct.
Another reason why your device cannot connect to the Internet is probably because it is connected to the wrong network.
To do this, always make sure that your device is actually connected to the network you have chosen.
You can check this via the “Settings” and “Wi-Fi” menu of your Samsung Galaxy A42.
This will display the name of the Wi-Fi network currently in use.
Once the connection to the correct network is established, check the password entered. The password entry is available in the same menu.
Deactivate the antivirus on your Samsung Galaxy A42
Antivirus programs are very useful to protect your Samsung Galaxy A42 from malware.
These programs are both offline and online threats.
But sometimes an antivirus can block Hotspot services.
These services being public, they can indeed represent a threat to the security of your Samsung Galaxy A42.
With some antivirus software, any Wi-Fi connection can also be blocked.
To counteract this, you simply need to disable the antivirus when using Wi-Fi.
Perform a Factory Reset
This step is the last option because it can erase all data from the device.
On the other hand, this method should be tried because a factory reset can remove all possible bugs on your Samsung Galaxy A42, we are thinking in particular of possible computer viruses that could make your Wi-Fi malfunction.
Be careful, this method will delete absolutely all data from your Samsung Galaxy A42.
Therefore, before you do so, make sure you back up the files in the device, including photos, videos and contacts.
Then, once these backups are done, you just have to open the “Settings”. Then go to “Backup and Reset” and select “Reset Factory Data”.
Then turn on your Samsung Galaxy A42.
You can immediately try to reconnect it to the Wi-Fi network. If this does not change, the last step you can take is to have your Samsung Galaxy A42 repaired by an authorized specialist.
Also, don’t hesitate to make use of the warranty if it is still valid.
