In the trilogy of Wi-Fi security blogs, I will introduce an occasional opportunity I encountered when scrambling Wi-Fi signals. WiFi, especially in the UK, has witnessed some WiFi explosions recently. 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 an official book on computer security will have a full understanding of CIA in security, the triad of confidentiality, integrity, and usability. This article will discuss availability, ie blocking WiFi signals. Now perfectjammer.com has better WiFi jammers that can help you.
A few weeks ago, I finally succumbed and bought a Nintendo Wii console for my children. I think this keeps them physically active while playing video games, and I think it’s fair. Anyway, I place the Wii under the main TV and then try to connect the Wii to my home WiFi network, which will allow the Wii to receive software updates, weather forecasts and even browse the web using the Wii Opera web browser. It was quickly discovered that the Wii could not connect to the WiFi network.
Therefore, after an hour of troubleshooting, by temporarily removing all my wifi jammer security and then plugging the WiFi router into Wii as close as possible, I found that Wii was unable to receive signals from my WiFi network at a maximum distance of 10 cm! Even so, the bandwidth (network speed) still seems too slow. Well, I gave up the day because the kids wanted to play Wii sports. I just thought the Wii’s Wi-Fi card was risky, but later that night, I encountered an epiphany while watching the satellite TV on the bed.
You see, I have satellite TV, and it powers the main TV. But, earlier this year, I wish I could watch all these beautiful satellite TV channels on my bedroom TV. So I bought a cheap “Technika” TV broadcasting solution. Local supermarkets cost £ 20 (about $ 40) instead of paying satellite companies more to buy a second set-top box, Sat Box. The device consists of a broadcast unit that is connected to the SCART output of a satellite TV decoder. The broadcast unit sends TV images, sound and even infrared signals from the remote control to the receiver, which is connected to the TV’s SCART IN Enter. From the bedroom. My epiphany is that in theory the TV broadcast unit is blocking the Wi-Fi signal, especially since the Wii and the TV broadcast department are under the main TV. So I turned off the TV broadcast equipment 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 had been turned on; in some parts of the house, the signal strength of the WiFi network was reduced by two-thirds, and at the bottom, all connections to the WiFi network were removed.
Therefore, an efficient 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 induce other attacks, but a good practice may be to enforce a non-WiFi policy, although you may need to check the relevant laws. broadcast.
