Some time ago we showed you how to hack the password of a Wifi, but in this case we will do the opposite, learn how to protect it and to kicking intruders out of our Wifi.
At first it may seem like a complicated task, but you will realise right now that this is not entirely true. The first thing we have to do is to detect that we are being robbed of Wifi, and to do this we will use tools that measure the speed of our connection. The most commonly used is TestdeVelocidad.esa website dedicated solely and exclusively to this function.
Something we have to take into account when starting the test is that, on our part, the network has to be totally free, that is to say, not being used for downloads or browsing, as this could distort the measurement. Another point is the fact that the speed that actually reaches our homes is not even close to what we have contracted, for example, with a 20mb connection I get about 7mb at most.
Well, once the problem has been detected, now the coherent thing to do is to confirm it by looking at the connections made to our router, for which there are some very good programmes, AirSnare, a little out of date, and Zamzom, the same, but a little more limited.
Now for the ways to protect ourselves, first of all we should try to use the new encryption methods for our Wifi such as WPA/WPA2/WPA2-AES.
The second thing is to change the password of our router, which normally comes by default and is easily detectable through lists like this one or this one.
By carrying out these tips, our Wifi connection will be safe from intruders.
