WiFi Jammer 

this is a great video! in the US its illegal to sell or use a jammer but not to own. Thank you for this informative video.

Saw a guy on the Long Island railroad with this and i have rarely been happier seeing him use it.

Great video! Very detailed with great instructions! Thank you!

Got to love that PRC quality control!

thank you for your video, it is educational. I here in the near future hope to start my little computer shop again ,but we live in a small community. I hope and have great respect for the law here in the USA. On occasions the law may need answers to technical questions. I aim to help them in every respect. I do see where jamming can have its uses though, like in a theater or concert possibly. its just one may never know the importance of a call or text if you would. As pointed out in your other subscribers replies, jammers can be tracked as well. To put it simple is knowledge is power.

Thanks for the video. Gave me some great ideas!

What a truly brilliant vid clever man 👍🏻😊

I knew there was a good reason to save those dozens of Wi-Fi antennas I got for free. At one time there was a small "antenna tester" called the AirHorn. It made a very effective Jammer (shh) too, and had its own GUI control package for the PC. It attached via a USB cable. As a jammer it was under-powered, but could be very useful in a large apartment complex for driving your neighbors to other channels

the transmitter you used in the video has 4 channels.can you specify the bandwidth of each channel and how much power is generated by the noise signal? many thanks

thanks for sharing andrew mcneil

Hi instead of jammer do you have 2.4Ghz amplifier for 4G booster circuit?

Love your videos thanks!

Can I use a 2.4ghz MONOPOLE antenna? Digikey sells them, they are a quarter size in length too.

Does this actually work? And if so wats the range

What do I do if my transmitter only has 3 places to connect the bridge to select the channels and anywhere i put it it wont work on anything but channels 9-13 The model is TX6729

Wifi jammers can be quite fun!

I am new to this particular type of project just curious how to increase the wattage to get a further range than just a few meters.

Que tal, tengo una consulta... también es posible bloquear las frecuencias 5.8 GHz? y si es posible se puede utilizar Sectorial 120° 19 dBi ubiquiti, para ese propósito?

Hi Andrew, please could you post the link for the switch?, they look pretty decent ones, thanks

Hi could anyone tell me if i could do this with just one antenna and one of the AV transmitter circuits?

I build the jammer but it doesnt work . I got one blue transmitter but dont know if i have to put à jumper on this one to?

Is there any way to solder and build an antenna for this because all the cables and antennas are a bit expensive all together, Thanks!

What products have an av transmitter in them? I might have one of them and can re use it instead f buying a new one.Thanks

how would you turn this into a gsm jammer ?

That resistor is to lower the amps the led can hold not volts. The led highest amps is approximately 1,5 amps.

So can you explain how this works and how would you jam 5ghz wifi and does this mean this would jam any signals at 2.4 ghz

what is the range like?

Andew the only boards i can get in the US only have 3 solder holes. Can these be used ? If so do you know where i run the jumpers from. I tried grounding but that didn't work.

mdk3 works for now. But i see this is like the old void11 program used back on pcim wifi cards. Can this be applied to cell signals. do they make 850mhz modules?

Hello, when building this do you have any heat problems? What is the range that this will work. Thank you

Is this working with each AV-Transmitter? I wanna overwrite a lower frequence and found some fitting Transmitter. How Much Power does one need?

Hi Andrew! I was wondering if you cut the pigtails in half or if they just came like that. Thanks!

I can't find the right antennas for the female adapters can you please send me a link

andrew what are the specs for the battery?

Where did you buy the plastic antennas? The link in the description is only for the pigtail. What type of antennas are they?

for making wifi jammer 3 same transmitter is to be used??

I was wondering how you ran all the power wires together and then all of the black wires together to make it that neat.

What is the SNR of the jammed signal (approx)?

Is there 5 ghz chips you could use as well?

I was wondering what good is a wifi jammer? i mean what do you do with it?

And what will happen if I connect all the chanel pins at the same time to the ground?

Great vid can the frequency be changed down to 900mhz ?

is it 1.5 battery or 3.7 volt battery? What resistor do you use?

What is the current draw for one of the transmitter pcbs?

How it work? Ur Av transmitter has 4 channel and u can crash all 13 channel wifi?

Blocking channels 1-12 should be plenty to knock out bluetooth which frequency hops all the way up to channel 14. I wonder how well bluetooth could be jammed with just one transmitter.

What is the bandwidth of the each channel in the transmitter?

Hi. Are you going to do a 5 GHz wifi jammer. or maybe do a 2.4 GHz and 5 GHz (Dusl) in the one case.

What is the range of this jammer? Thanks.

Any plans to do a 5.8ghz update?

Make many of these and hide them in starbucks

I really think you have to be considerate as well as very careful using such a jammer. What's good enough for the goose is good enough for the gander. I'd be very upset if some one was doing that to me. I'd use a WiFi direction finder to find out who was doing it and then there would be payback. Back in the days of CB Radio I tracked down some one abusing the CB bands, swearing, causing all sorts of problems night after night. I built a micro transmitter designed to transmit a messy carrier signal into all channels. It was only the size of a cigarette pack and transmitted only a very low power signal so I threw it onto his roof very near his antenna. It slide down into his gutter and shut him down for a couple weeks without bothering any one else until the the battery pack gave up. The really funny part was, he knew I fixed CB radios and brought his kit to me to fix. Needless to say I had serious problems fixing it. It took me weeks waiting parts it certainly did not need!

hello Andrew ! i live by the sea and there is no adsl ( no wired phone ) so the only way to connect is through a hotel i bought ALFA WiFi adapter ,,, it worked fine the first few days than it started disconnecting and reconnecting by itself ,, i spend hours googling to find a solution ,,, many say drivers ..updates ect.. all that didnt work i even formated my pc win 10,, than someone said alfa needs 500ma at least to work so i bought usb hub and a 12 V charger than the whole thing blows up, the usb hub and the alfa is there away to connect to the hotel ? the distance is only 300 meter please help ! i had enough buying data on my phone

This is a wonderful video ! How far do you think it works?

Can you use it or modify to use against Bluetooth?

can i consider wifi jammer as a embedded system

I have ordered all the parts... I'll let you know if mine works. My purpose is to help with temporary privacy of closed meetings. If there are any wireless cameras or microphones in the proximity, then hopefully they would temporarily be disabled during our meetings.

This is a very interesting video clip, it looks very easy but i don't think id be up to making one of these units.. Have you ever made one of these units and sold it on your shop.. Terry

You do great work. Do you need a helper?

Perfect way to troll your school. I think I'll build one.

can you use this for mobile data jamming

is the higher the dBm the better the signal and the same for is the higher dbi antennas better

Hi Andrew, I'm a penetration tester and this WiFi jammer would come in extremely handy in my testing as I normally need to run a deauth against the ap's. I've noticed you are not selling them in your shop, is there anyway I can purchase one from you, or can you recommend somewhere I can get one? Thanks

Hola tienes algun esquema para su construccion ? Gracias

Hello, your video has helped me a lot for the construction and presentation of one as a school project, so I thank you for the video, however I have some questions that I wondered if you could answer: With the Jammer that I have built, the signal is not inhibited , but dims, in my tests a 70mbps download and 31mbps upload connection dims to a 4.70 on both. Why has this happened? Why hasn't it been disabled? The components are the same and the only difference is the battery that in my case was used a 3.7 volt lithium cell phone battery, it was slightly discharged. Secondly, the inhibition area is quite poor, the devices to be inhibited must be extremely close for their signal to be attenuated. Finally, what is the spectrum analyzer program or device that you use, both the tablet and the computer?

transmitter wont ship to my country, is there any other alternative?

so the chip has multiple holes for different channels and each hole has a different channel. how do you select each channel, do you ground it? thanks!

I'm confused with jumpers is there detail plans on how to set them to jam all channels ?

How to block the radio signal or jam it with devices, e.g. computer keyboard etc. Because I had an attack and the one who did it knows my frequency of devices and knows when I turn on the computer etc.

How much meters does it work?

could you use AA or AAA batteries?

what are these transmitters actually transmitting?

Nowaday WiFi Jammer is very useful.It can protect our privancy well.

how many modules did you used?

Anyway for a link to the transmitter?

What's it do ? Just sends deauth packets ?

Are you working on cellular jammers too

I too was wondering about the battery/power supply. As far as I can tell, the transmitters are powered by 5V, what am I missing? Thanks ahead of time for your help.

Can it jamm an Rc signal

Hi Andrew! Nice project. I ordered 4 boards and the are different from both of yours. I wrote to the seller and he told me that I have to place the jumpers between pin 4 and 7 were 7 is ground - vcc, then lets say 5 and 7, and 6 and 7 and leave one board like you with no jumpers... Does it sound logical to you to use the ground? He says that way I will get channel 1 -2-3-4... I would love to send you a closeup picture of the board, but I do not now how. If you can give me a hand I would appreciate it very much. Cheers

i can modify for bluetooth speakers? how i can do it?

Is this also block bluetooth signals?

whats the 4th transmitter

i ordered a 17 Watt professional jammer from China, it went through customs. It was so powerful it was jamming 2.4, 5, vhf and uhf signals. I got scared and sold it. It was cutting off everyone across the street and block, it was too much. I will build this for sure..

I am having trouble with civilian drones eavesdropping at my windows at night. I want to disable it.....will this work for that?

hi, could you at least give me the name of the antennas you use? can't seem to find them anywhere. Thanks!

Where do I buy the antenna???

Does it works on 5ghz?

Can i use xl24017 transmitter

Need those at polling stachon

Sadly I don't need any wifi jammers to get shitty wifi at home :(

what's the range?

Thanks for the vid. Where can i get the 4w amplifier you used in your other jammer project? I have only found very expensive ones online.

how to put the modern house party next store to rest. hope no one gets out the cds..

Great! Just one thing I didn't really understand yet: did you solder the three different channels to gnd or with what did you connect them? Except that, everything is very clear to me and you explained well. Thanks a lot!

what are the specs of the battery?

lol love it great idea

do you sell of of these? and how mutch??

Do you have this for sale?

alguien seria tan amable de decir que que materiales uso en español? somebody can tell me what materials he use in spañish please?
