Hello friends, welcome once again to radio bunker, we continue with the series of videos about PORTAPACK. This time we are going to be seeing an answer to a question that has been asked a lot on the internet about whether it is possible with the PORTAPACK to block or interfere with a Wi-Fi signal. Well, without wasting any more time, the answer is yes and no and because if not, well, first Wi-Fi is a communication protocol that was conceived, its nature has as a priority to be highly resistant to interference, so we start with, let's say, the difficulty of the Wi-Fi system. communication is very resistant to blockages or radio interference but if we study a little how the Wi - Fi works we will be able to see that if it is possible by making a small exception with a small trap we will be able to block or interfere with a Wi-Fi signal such as If you and you see in the PORTAPACK if one goes to the transmission menu we have a function that is the jammer is the one that we are going to be using and we are going to go into that a little later before we are going to have to study a little how The wifi system works to understand and know how to be able to carry out the interference very well, we are here, we have put up a small notebook to be able to analyze what it is like the operation of the wifi and how to proceed to how to proceed with its interference or perfect jamming uefa and wi fi which frequencies works well basically the domestic wifi the one we have in our homes works let's say in two frequency bands mainly one is the 2.4 gigahertz and the other is the newest one that is being used and that it is increasingly common to see the one that is around the perfect 5 gigahertz in which we are going to focus today on the 2.4 gigahertz because it is the one I have here at home and that is where we are going to do the island experiment to which we are going to interfere is let's say even also a range although the two frequency ranges the hacker efe can cover those at the 2 point of 2.4 gigahertz we can have a little more success because the antennas are also a little easier to find but hey, then let's see how the wifi works and in what frequency range and why I told them first that it can and can not be very well we are going to make a small graph of how the wifi works here we are going to have frequencies in this axis and in this we are going to put amplitude the wifi works the wifi from 2 to 4 arrives here it works by channels in a frequency range That starts from 2 we are going to wear it yesterday to make it easier for 2401 megahertz and ends at what would be 2,495 megahertz. ok that is the frequency range that wifi works in this band that passes within this frequency range we are going to have different channels we are going to have channel 1 channel 2 channel 3 tata tata tata up to channel 14 each of these channels for example to give you an idea channel 4 easier channel 2 works this is channel number 2 channel number 2 works between 2 thousand 406 megahertz to 2000 428 2,406 to 2428 that is to say that each channel has a bandwidth 22 mega perfect and more or less have the structure of how the wifi works us in our homes we almost always the router does automatic way but we're connecting to each of these channels of course always what is recommended is to use the channel that has fewer users so that the Wi-Fi internet goes better, faster and with less interference, perfect what is it that matters to us? Here is the first problem, look at the total width of the Wi-Fi all this Let's say width of the entire band is very very very large that is, it is 2,495 minus 2,401 are 94 megahertz this is a very very large bandwidth and if we take into account that the hacker uses the maximum bandwidth that can be transmitted is 20 megahertz approximately we see that we are facing a problem because we cannot cover all the wifi to attack it to block it to emit a signal and cancel it we cannot because the bandwidth is very wide this in our hacker efe the maximum that can be 20 m yesterday but but notice you that each channel its bandwidth is 22 megahertz that is to say that I am going to be able to interfere a channel but not all at the same time so this is the reason why I told you that if you can block making a Gaming attack or let's say interfere with the wifi I said yes and no because if you can a channel but you can not the entire wifi band, that is, all the channels then with this already in mind with this already studied blog or the theoretical step for To do the attack would be to know which wifi here is the wifi channel and the pc or mobile phone that we want to attack is connected to select it, enter these values ββin the gaming hummer application of the hacker efe and in theory it should be blocked, so let's move on to that. I hope this has become clear anything let me comment on video and already I say and want to subscribe for more videos are all invited we then find out which channel is connected to my wifi and we will attack him what such good friends are already here On the pc we have everything configured and what we are going to do is find out which Wi-Fi channel my computer is connected to, a caveat and something very important to keep in mind is that my router only works in the two points 4 arrives here it has no bandwidth 5 gigahertz, so that's an advantage, it makes the attack easier to know what the water is like or where the water is, which channels are connected to our pc to wifi, it's very simple, let's go here networks we select these networks properties we go down a little and we see that here it appears that the network channel is channel number 11 so well we look for the channels we are going to see that channel 11 which is where it is connected I am not going to walk a little bit channel 11 It goes from 2 thousand 451 megahertz to 2 thousand 473 megahertz perfect then the only thing that remains now is to enter this data in the jammer application of the porta pack transmit and well see if we can attack my own Wi-Fi network very well friends we are here with it porta pack we already have located the wifi channel to which my presence is connected so what we have to do is simply enter the values ββin the jammer application and this and then transmit to see what happens we are going to transmit we are going to call and what we have to do is first of all we are going to center our frequency we had said that channel 11 started at 2,451 and ended at 2,473 if the bandwidth is 20 m yesterday 22 what we are going to do is add to the lower part 2 thousand 451 plus half the bandwidth would be in 2004 61 in 2000 40 31.00 there we have the center and we already have the center of the channel what we are going to put now is a bandwidth that bandwidth we had said that the maximum that the hacker efe gives is 20 megahertz, also, notice that the interference signal is going to start at 2,451 and it will end at 2,471, it will cover almost the entire channel d on channel 11 of the wave and what we are going to change we are going to change that generates a tone we are going to put it to make a tone we are going to put it let's try first with an fm tone ok and see what happens very well let's go Let's see if we are lucky, very good friends, well, I already have the pc here which is going to be the victim of the attack and I already have the porta pack here with the data entered, I have connected remote administration because why is this, let's say is a connection that It has no basis or anything like that if I put a video or from YouTube there is probably always a small buffer, let's say that no matter how much the transmission is cut, a little bit is recorded on the pc and we could not see the effect immediately instead, here we are seeing that in the round trip transmission to Argentina they are 320 milliseconds and the important thing is to note that it indicates the lost packets so as soon as we activate our signal blocker the hammer we will immediately see if there is a loss in the data if it is affecting the transmission that we have configured is interesting to know Also that the power is not very great and I am not very distant from the pc and even well the router is over there more or less so well let's go and see how we do in the application of the porta pack the only thing that I have done that before I had not commented to him is to activate that green which is the range level so that the system can say activate the range that we have activated very well we are on channel 11 is the pc no s If you can hear the white noise from the radio in the background, we are going to start the transmission and it automatically cuts out and the lost packets begin to increase, finished and recovers, so perfect, the signal blocking is working, I start again and come. How do you increase the packets, deactivated the function and the packets stabilize again, let's see if I do a little bit of let's do an experiment, I'm going to set the volume a little higher, I'm going to zoom out to see what range we have perfect from here very well I'm going to go to another part of the room I try from here and also well apparently this works very very well it could even be improved let's leave this over here let's lower the volume this could be improved of course with an antenna of 2.4 since it was adjusted I the truth that I do not have so well I am using this even if we use a directional let's say the effectiveness of the block would be much higher eg ro good it has been shown that if you can block a wifi signal but the problem is that we only have to know the channel we can block a wifi channel not a complete signal good it ran out of battery yes enough that it was turned on but it works without problems Thank you very much hand up comments and do not stop subscribing
