All the news on TCL 20 SE in our articles.

It is very convenient to use Wi-Fi via your TCL 20 SE, especially in public areas or inside the house.

But it is not uncommon that your TCL 20 SE 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 TCL 20 SE: 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.

Our other articles on TCL 20 SE can help you.

Therefore, it is not uncommon to prefer to connect your TCL 20 SE to Wi-Fi rather than using 4G or 5G cellular data service.

Not being able to connect to Wi-Fi with your TCL 20 SE 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 TCL 20 SE.

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 TCL 20 SE

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 TCL 20 SE.

Open the “Settings” menu, then “Additional Settings” and then “Date and Time”. From there you can set the date and time on your TCL 20 SE.

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 TCL 20 SE.

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 TCL 20 SE 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 TCL 20 SE 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 TCL 20 SE to try to get an internet connection.

Wi-Fi too slow on TCL 20 SE

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 TCL 20 SE.

In some cases, the bandwidth per device is itself limited: your TCL 20 SE 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.

Limited Wi-Fi

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 TCL 20 SE, 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 TCL 20 SE 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 TCL 20 SE

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 TCL 20 SE 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 TCL 20 SE.

These two methods are the most basic steps in troubleshooting a device that does not connect.

If both methods did not work on your TCL 20 SE, you can try the following methods.

Check for forgotten networks on your TCL 20 SE

The Forget Network feature is designed to eliminate Wi-Fi on your TCL 20 SE.

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 TCL 20 SE.

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 TCL 20 SE

Antivirus programs are very useful to protect your TCL 20 SE 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 TCL 20 SE.

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 TCL 20 SE, 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 TCL 20 SE.

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 TCL 20 SE.

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 TCL 20 SE repaired by an authorized specialist.

Also, don’t hesitate to make use of the warranty if it is still valid.

Learn more about Wi-Fi

A device that can use Wi-Fi (such as a personal computer, video game console, or your TCL 20 SE) can connect to a network source such as the Internet via a wireless network access point.

These access points (or “hotspots”) have a range of about 20 meters indoors and even more outdoors.

The coverage of access points can cover an area of a few meters or several square kilometers: this is made possible by using several overlapping access points.

Be sure to check that you are within the coverage area by connecting to your TCL 20 SE.

“Wi-Fi” is a trademark of the Wi-Fi Alliance and a brand name for products using the IEEE 802.11 family of standards.

Only Wi-Fi products that have completed the Wi-Fi Alliance interoperability certification test, such as your TCL 20 SE, may use the “Wi-Fi Certified” name and mark.

Wi-Fi provides services in private homes, main streets, stores and public spaces via free or paid Wi-Fi hotspots.

It is very convenient to connect to the internet with your TCL 20 SE in all these places. Organizations and companies, such as airports, hotels and restaurants, usually offer free access points to attract visitors.

Feel free to try to connect to various access points with your TCL 20 SE to test your connection.

Operators or administrations who wish to provide services or even promote business in certain locations sometimes offer free Wi-Fi access: take advantage of it!

With the advent of MiFi and WiBro (portable Wi-Fi routers, as available with connection sharing on your TCL 20 SE), users can easily create their own Wi-Fi access points: Internet is then available via a cellular network.

It’s a very good solution to save money and cancel your classic internet subscription: your TCL 20 SE can be used as a modem for any home via shared Wi-Fi connection!

Now, Android, Bada, iOS (iPhone), Symbian devices, including your TCL 20 SE are able to establish wireless connections.

Wi-Fi also connects places where you normally don’t have access to the network, such as kitchens and garden houses.

We hope we have helped you to solve your problem with the Wi-Fi connection on your TCL 20 SE.
