WiFi jammer to solve some public network problems

In the “Wi-Fi Security Blog Trilogy”, I will introduce the opportunities I occasionally encounter when interfering with Wi-Fi signals, especially in the UK, where WiFi has recently seen some explosive developments. In the UK, entire urban communities are already compatible with WiFi. There is no doubt that we will increasingly rely on WiFi networks. Anyone who has read official books on computer security will have a comprehensive understanding of the CIA’s triad of security, confidentiality, integrity, and availability. This article will discuss uptime, that is, blocking WiFi signals. Now perfectjammer.com has better wifi jammer that can help you.

A few weeks ago, I finally gave in and purchased a Nintendo Wii game console for my kids. I think this will keep them physically active while playing video games, which is correct. Either way, I put the Wii under the main TV and try to connect the Wii to my home Wi-Fi network. This will allow the Wii to receive software updates, weather forecasts and even browse with the Wii Opera web browser The internet. Soon it was discovered that Wii could not connect to WiFi network.

Therefore, after one hour of troubleshooting, temporarily removing all security protection from the wifi jammer and plugging the wifi router as close as possible to the Wii, I found that the Wii cannot receive the signal from me. The maximum distance of the WiFi network is 10 cm! Even so, the bandwidth (network speed) still seems too slow. Well, I gave up this day because the kids want to play Wii sports. I just thought the Wii card for Wii was risky, but later that night, I encountered an eye-opener while watching satellite TV in bed.

You see, I have satellite TV, which can play the main TV. But, earlier this year, I wish I could watch all these beautiful satellite TV channels on my bedroom TV. Therefore, I purchased a cheap “Technika” broadcasting solution. The local supermarket will spend 20 pounds (about 40 US dollars) instead of paying more money to the satellite company to buy a second set-top box Sat Box. The device consists of a broadcasting unit connected to the scart output of a satellite TV decoder. The broadcasting unit sends TV images, sound and even infrared signals from the remote control to the receiver, which is connected to the Scart input on the TV. From the room. My epiphany was that in theory the TV broadcast unit would block the Wi-Fi signal, especially because Wii and TV broadcast services are located under the main TV. Therefore, I turned off the TV streaming device and immediately connected the Wii to the Internet.

The next day, I did some experiments with my laptop. I noticed that the TV broadcasting unit has been opened. In some parts of the house, the signal strength of the WiFi network was reduced by two-thirds, and all connections to the WiFi network were removed downstairs. Therefore, an effective Wi-Fi jammer can be obtained at a very cheap cost. I think with some custom settings, we can expand the range of Wi-Fi interference and make it a mobile device. I can think of many bad uses of WiFi interference, especially to cause other attacks, but it’s good. Although you may need to check applicable laws, in practice there may be policies that prohibit WiFi. broadcast.
