How to know if the Internet is being stolen via WiFi easily and quickly? Step by step guide

A recurring problem that exists in wireless connections is the entry of intruders or people who are not authorized to the WiFi network , in this way we have serious inconveniences regarding connection speed, as well as jeopardizes our security.

There are many ways to expel these unwanted visits, some of them are directly related to the privacy settings of our router. If we don’t want to have problems, we will have to follow the steps that we will mention in the following paragraphs to have a perfect shield of the router .

So that you know a little more deeply about WiFi theft, we have written this report so that you can configure your router and thus strengthen it against foreign income. We also bring the best applications related to this topic that will serve you incredibly.

What are the main problems that cause you to steal the Internet over WiFi ?

When we think that sharing the Internet signal with unauthorized people is simply an act of our selfishness, we are wrong. Because, in addition to dividing bandwidth into more devices, we will also have other much larger inconveniences.

Next we will show what are the main problems when strangers enter the WiFi network without our authorization:

Speed ​​loss

If we have a router with 2.4 GHz frequency that has 13 channels, these are saturated more by having a greater number of devices connected in the same network, so it is necessary “clean that highway” of the Internet so that we can transit more quickly and safely.

Access to our privacy

Acceso a nuestra privacidad

As with almost all networks that are not configured, the devices that are part of it can access each other. In this way , an intruder can enter our private data in a very simple way , thus generating a very high risk in our privacy.

Change in revenue data

If we have not been able to block the entry of an unwanted person, they can access the configuration of our router and change, among other things, the SSID and password , generating that we do not We can enter our WiFi network.

We can solve it by calling our Internet operator to manage the necessary changes.

Disclosure of our SSID

Another factor to consider when intruders enter is that, they can do absolutely nothing for us to realize, just share our password with other people, so the number of connected devices will be increasingly large .

In this way, the connection speed will decrease considerably. This will also put our security at risk.

Why shouldn’t you let anyone steal internet from your WiFi? Causes

The reasons why it is not convenient for us to steal WiFi are:

Login with our IP

When we browse the Internet, the IP address that identifies us is the one that our operator gives us, therefore, if you enter any intruder and carry out illegal activities, they will be registered with our address .

In this way, one of the most important causes in terms of legality is to have absolute control of access to our wireless network.

Document theft

When our WiFi network is illegally accessed they can access our devices and thus obtain all the documents that we have stored in them.

In addition, you can enter different passwords from banks or other sites that are really private and be able to lose money without us noticing.

Join our Web Cam

Another factor to keep in mind is that, strangers or unauthorized people entering our network can have access to the webcam of some of the devices so our privacy has a high risk of being violated.
