In these days having a WiFi connection to access the Internet is essential. The truth is that without an Internet connection we wouldn't even be able to finish organizing our day, as we are used to.

In short, today the internet is not only a tool that some use to work, but it has also become a means necessary for fun and entertainment, for example Facebook, for keep in touch with our friends via WhatsApp, and also for watching movies on a smart TV. Therefore, beyond the purpose for which we use a WiFi connection, the truth is that its presence has become ubiquitous.
It has become so important that today it is not enough for us have a WiFi connection in our homes and workplaces, but we need to connect to public WiFi networks in bars, hotels and even in public spaces.
What is WiFi?
In a broad sense, the WiFi is a radio signal that allows us to connect to the Internet without wires and in recent years it has spread to all corners, regardless of the cultural and socio-economic differences of its users.
It was developed in the late XNUMXs by a consortium of companies, now called the WiFi Alliance, with the aim of creating a method for connect to the internet quickly and easily, and completely free of connections.
This is the reason for one of the main advantages of WiFi lies precisely in the fact that you can have wireless Internet, making this a completely mobile connection, which means that whenever we have a Wi-Fi network nearby, we are able to enjoy the benefits of the Internet simply by connecting our smartphone, tablet or laptop to this network, both private and public.
How to connect to WiFi: the first step, see the available networks
connect to a Wi-Fi network and be able to use the internet on our portable devices, the first thing to do is to view the WiFi networks available around us, through the device we need to connect.
Luckily see WiFi networks to connect in Windows it is very simple because for example on a PC or laptop as soon as the system starts detect WiFi signals nearby warns us with a pop-up message, to know if we want to connect or not.
Manually, we can see the list of WiFi networks available in our area by clicking on the WiFi icon located in the notification area of the taskbar, near the clock. Once we click on this icon, we will see the WiFi networks available.
Once we can see the WiFi networks available, if we want to connect to one of them, we have to click on it and then press the button "Connect".
If it is a protected WiFi network, will ask for access to the password, which we must write in the box that will appear later.
It should be noted that in the case of a open WiFi network, ie not protected, it will not be necessary to enter any type of password to access the network.
Automatically Windows system will connect us to the chosen WiFi network not as soon as we have performed the steps mentioned above, without having to do anything else.
Similarly, when we need to connect to the internet via Wi-Fi in our mobile devices, such as an Android cellphone, we can access the WiFi network we want to connect to via the "Settings".
Here we have to click on the section “WiFi”, where the different WiFi networks available will be shown, and to connect to one of them, all we have to do is click on it. If it is a private network, there will ask you to enter the corresponding password.
I can't connect to WiFi
As we have seen, connect to WiFi it's a really simple task from any device or computer that allows it. However, it can happen that it is impossible for we connect to a WiFi network.
At this point, it should be noted that most of the time cannot connect to the Internet the problem it has more to do with our WiFi connection than problems with our ISP's internal or external infrastructure.
As mentioned, WiFi connections can be problematic for many reasons, which undoubtedly complicates the search for the true cause of failure. This has a lot to do with the type of connection we have, the device and its operating system, as well as other multiple variables. This means that the WiFi problem can be different for each particular case, that is, there is no single and specific solution.
However, we can do a series of fairly standardized checks, provided that the hardware involved, i.e. the router and the WiFi chip, are working properly.
Then we tell you what the main causes are which are the reason for which you do not connect to the Internet, as well as a basic solution that can get us out of the problem.
WiFi appears but I cannot connect
This is the problem that prevents us from connecting to WiFi most popular of all. Fortunately, the solution is simple, all we need to do is change the network SSD.
Problems with WiFi modem security
Another very common problem is certainly theunable to connect to WiFi a due to compatibility issues with the security protocol.
This can happen because there are still a large number of WiFi routers that aren't compatible with WPA2-PSK security type. At this point, it's best change the security type to WPA-PSK or even WEP.
The frequency of operation of the router
Also, another one very common problem is to connect to WiFi because the frequency with which the WiFi router is in operation is not accepted by the device we are trying to connect with.
To fix this, we need to log into the router and change the operating frequency from 5Ghz to 2,4Ghz.
Is the name of the WiFi network displayed?
Another of the most common problems among computer, phone and tablet users is to see the name of the WiFi network we want to connect to. This can be mainly due to two points.
The first is that we do not have the wireless function enabled in the device with which we want to connect to the network.
The second problem is that the name of the WiFi network, i.e. its SSID is hidden from view. To solve this problem, we have to access the router settings and change the parameters to show or hide the WiFi network.
Check the SSID of the WiFi router
In some situations, especially after some problems, it is possible that the WiFi router shows a different network name or SSID than the one we connected to. To correct this problem, all we need to do is access the router configuration and change the network name to match what we were using before the problem.
It should be noted that the appearance of the router interface may vary depending on the brand and model, however, the name of the functions is similar in all.
At this point, we must keep in mind that it can also happen that the SSID of the router is hidden, the which means it cannot be visible on devices. The solution to this problem is enter the modem or router settings and change the option to show or hide the WiFi network.
We connect but cannot navigate
Finally, after doing all the relevant checks and applying the solutions to the possible problems, it could still happen that although we connected to WiFi, the truth is that it is unable to browse the Internet.
Perhaps this may sound strange, however it is a fairly common problem and could be due, for example, to the fact that the network is out of range or that we have viruses or applications that prevent us from connecting. At this point it will be better uninstall all suspicious applications and use a good antivirus.
The WiFi connection is intermittent
It may also happen that the Internet connection is intermittent, the which may be caused by another WiFi modem or wireless device interfering with the signal.
This can be solved by changing the transmission channel of the modem.
Problems with devices and computers
When the inconvenience inability to connect to WiFi, where even some or all devices fail to even detect the existing Wi-Fi network, we must take into account that this could be due to various factors related to problems with the modem, router, or even the equipment itselfsuch as your phone, tablet or computer.
Faced with this situation, in principle the ideal is check if the problem occurs on one computer only or on all, in order to assess whether the problem is on the router or on the devices.
On notebooks: se our notebook connects to the internet, but it does not detect the signal of the existing Wi-Fi network, we must bear in mind that most of these types of laptops have a button that allows us to turn the wireless adapter on or off, a useful feature to extend battery life.
Therefore, if this button is in the off mode, the notebook cannot detect the existence of Wi-Fi networks.
On the other hand, if the notebook has the Windows 8 operating system, we must also bear in mind that it includes one configuration for power management, inside which is enabled by default when Internet is not used it is disabled by the Wireless Adapter software, to save energy.
You can disable this feature to access the "Control panel", then there is the card “Power Management” and then disable the option "Allow the computer to turn off this device to save power", thus changing the properties of the notebook or netbook wireless network card.
On the router: when we notice that the problem is in all or almost all the equipment and devices that we want to connect, one of the best options is to try the reboot method, as the truth is that sometimes the Internet signal can become weaker and more difficult for devices to detect.
In this case, what we're going to do is turn off the Wi-Fi router, then we will wait 20 or 30 seconds, then we will restart the device. In general, the router has an on / off button on the back, however, if this is not your case, we can resort to the direct disconnection of the cable from the unit to the outlet.
Likewise, it is always advisable to check if there is no external interference, since we must consider that some equipment can become an obstacle to the WiFi signal, such as some microwaves, some wireless landline phones, some televisions, which emit electromagnetic signals.
On the phone or laptop: a another problem that can arise is when we live in a building or are surrounded by neighbors, a scenario that is repeated in practically every corner of a moderately important city.
The large number of Wi-Fi signals that our router is able to track in this type of situation is very large and can cause the our wireless signal is not the first to appear in the list of available connections.
In this case, we can automatically configure the device to connect to our network, the which will save us time, plus we will have a connection available as soon as our phone, tablet or laptop is within the transmission range of the router.
How to improve our Wi-Fi connection
A really decisive point in this aspect is the position of the transmitter, which is perhaps one of the things we need to pay more attention to, since the Wi-Fi transmitter, if it is in an inappropriate location, will not be able to provide the best signal quality for which it was designed.
We have to place the Wi-Fi device on a mobile, must be raised from the floor, as well as observing that between this and the PC to which it sends its signal, no iron or metal surface must be interposed, as it would significantly degrade the signal quality.
Also, if possible, we should keep the device away from cordless phones or microwave ovens.
Another aspect to take into consideration is the improvement of the emission distance. In case somewhere in our home or office, we don't have good reception, the best we can do is implement the use of a signal repeater.
If what we want is optimize the reception of the WiFi signal, one of the best alternatives we can opt for is the use of a Wireshark network software, which will be a lot useful for getting the best Wi-Fi signal.
It is also very advantageous to use the WPA encryption method, which is much superior in terms of connection security to WEP.
