Spain is one of the countries with better fiber optic coverage in the world. But our day to day is not very different, digitally speaking, of other countries. In mobility we depend on the mobile phone networks of the different operators and at home and at work we usually use a WiFi connection.
This connection is produced by a router that is the one that creates the network to which we connect. But That network can be safe or notdepending on the decisions we make. By default any configuration has basic parameters, but it is a good idea to make certain changes to have a connection more resistant to attacks and failures.
That is why it is recommended change the user and router password, change the name of the Wi -Fi network to which we connect or Use an especially safe password. All these actions can be done without technical concentrations, and relatively quickly, but they will help us a lot for a long time.
Ensuring access
To be able to Enter the adjustments of a router a user and a password is needed. Both data come as standard in the box when we buy a router or when the operator technician with which we have hired the Internet access line at home is installed. These data are usually very basic, and the user is usually simply admin and the very basic password.
This is a problem because operators information leaks can give access to these data, and we would be exposed to be like that. In addition, each router brand usually uses a combination of numbers or a very similar structure.

What we have to do is enter the configuration, Change the user and router access passwordat least that of the administrator and, of course, memorize it so as not to lose it since if we should not restore the state of the factory, with what it implies. It is important to note that these data are not the same as the following, those of the WiFi.
New Wifi and Password
The first thing we should do When configuring a new wifi is to modify not only the password that comes by default, but also the SSID. The latter is the name of the wifi, what appears on the mobile screen when we are looking to connect for the first time. To change it we simply have to go to the router settings and put a new one.

The same goes for the network password. The best is Do not use the one that comes by default printed on the back of the router. A long but simple password is better, one that has numbers and symbols. Using a phrase is a good idea, because it usually has all kinds of characters and is easy to remember. For example, we could put something like “My birthday is August 7, 1978”. It has length, numbers, letters and special characters.
Update the firmware
As with the rest of computer devices, routers have their own simple operating system that allows them to operate. The firmware, which is what is called, is updated from time to time, depending on the company. It is done to implement new functions but, above all, to cover security holes.
That is why It is important to keep it updated. In this way we know that we minimize the possibility that there is some kind of attack to it, whether from the Internet or from the physical surroundings of the same with antennas or other devices. This is important to do it the first time we set up the router, but it is also a good idea to look a couple of times a year at least to see if there are changes.
Types of encryption
Routers have encryption systems that allow comuncations to be safer. These systems are optional, so we must confirm that we have them assets. The most normal is the so -called WPA in some of your configurations. Depending on the router we will have WPA3, WPA2 or a different one.

It is best to choose the highest available For the Wi -Fi network we are configuring. If at any time a device cannot connect to the network by it we can temporarily turn it off, configure the device in question and then proceed to enable it again.
Remote access
Many routers have Remote access systems QThey allow them to be used from the outside. This is somewhat comfortable if we use it a lot, but it is also an attack vector because any part of the world could enter. If we turn it off, we prevent that.
Thus, we must search the configuration sections such as remote access, WAN or the like. When we locate them we can deactivate them. From that moment we must be within the scope of the Wi -Fi network to be able to operate with the router adjustments, which will be normal in 99% of cases as little.
WPS
The last adjustment to consider is wps, an pairing system that replaces the password with a pin And that makes the configuration of a Wi -Fi device much more comfortable, but it also makes it more insecure. This option is used by pressing a physical button on the router, but if we want it to be as sure as possible it is a good idea to deactivate it.
Normally this is recommended in public environments, such as offices and the likebut at home it does not seem that it will be the reason D attack on our wireless network. However, it is good to know that it is something to be aware if we are analyzing the security of our domestic connection.
