Now, with the development of the Internet, wifi has become an indispensable part of our lives, so do you know how to block wifi?
Many people have wireless routers at home to meet the needs of devices to access the Internet, which has also spawned a lot of people who surf the Internet. Isn't your home wireless network being used by others? Has your wireless broadband been "rubbed" by others? How to block wifi from others?

First enter the web configuration interface of the wireless router AP, find the basic settings menu to modify the SSID name, select Disable SSID broadcast, then modify the default IP address of the wireless router AP, turn off the DHCP function, and adjust the wireless transmit power to control the wireless network coverage.

Enter 192.168.1.1 in the IE address bar, and then see the password and user name, both are admin. This will allow you to see the currently connected project. If there are redundant devices, they will be cleared. If it is a wireless router, it is best to turn off the wireless broadcast.
Step 1: Turn off SSID (network name) broadcast
After turning off the SSID broadcast of the wireless router AP, it is difficult to find this wireless network when searching for wireless. The setup method is very simple. Enter the web configuration interface of the wireless router AP, find the "Basic Settings" menu, modify the SSID name in it, and then select "Disable SSID Broadcast".

Step 2: Turn off the DHCP function

After turning off the SSID broadcast, we also need to turn off the DHCP function, which means that the wireless router/AP cannot automatically assign IP addresses to wireless clients. In order to further prevent being "robbed", we'd better modify the default IP address of the wireless router/AP. For example, the default IP address is: 192.168.1.1, we can modify it to 10.0.0.1. Enter the web configuration interface of the wireless router/AP, find the "LAN Settings" menu, then modify the default IP address, and select "Disable DHCP Server" to confirm.

Step 3: Reduce the transmit power and upgrade the firmware

If some wireless routers/APs currently have the function of adjusting the wireless transmission power, the coverage of the wireless network can be controlled by adjusting the wireless transmission power, making it difficult to search for wireless signals. Upgrading the firmware of the wireless router/AP is also important, because it not only fixes some security holes, but may also add additional protection features for better security.

Generally speaking, you have to log into the router background to hide the wifi signal. You can hide the wifi signal by logging into the router management background and selecting wifi settings to turn off the ssid broadcast.
If you feel that the above steps are too many and too complicated, you can also consider buying a wifi signal jammer, which can easily help you solve the problem of being hacked on your network.

More and more people pay attention to the development of signal jammers

Yakima Training Center, Washington - Soldiers of the 1-2 Stryker Brigade Combat Team learned about the dangers of enemy jamming technology during a degraded environment course at the Yakima Training Center, Washington, Nov. 5-7.

The course focuses on GPS interference identification and reporting, while emphasizing the importance of not relying on electronic technology for navigation.

"A lot of people don't realize the capabilities of our adversary in terms of jamming," said Lisa Prue, a training exercise instructor for the U.S. Army Space and Missile Defense Command/Army Strategic Command. "We try to introduce them to these concepts, and Train them how to mitigate this when they find themselves in a GPS jamming environment."

Training is important because soldiers in the future are likely to fight in GPS-degraded environments, Sgt. 1st Class Juan Jaramillo, an EW sergeant with a 1-2 SBCT. Minimizing this training will help mitigate many of the risks they will face in the future.

"We also teach some basic techniques in the classroom, such as body masking, digging holes in the ground, using terrain or metal objects to block jamming signals in order to re-acquire GPS signals," Prue said. "Old school techniques are also important, being map savvy. And compass skills are important."

According to Prue, one of the most important things a soldier can do is report a distraction.

"We won't be able to find or target the jammer until a report is made," she added. "The jammers are easiest to find by field personnel on a mission. When the information reaches the appropriate channels, we can find the military signal jammer and process them."

Anyone can use a GPS jammer - making it even more important for soldiers to report the source of the jam, Prue said.

 

"Anyone in the world can go online and buy a GPS jammer," she said. "If you google it, you'll get over a million hits for GPS jammers. This can be purchased commercially. Our potential adversaries will have more advanced capabilities.

As the college entrance examination season is approaching, many schools are facing the problem of preparing for the college entrance examination room, such as the purchase of materials and equipment, which are necessary to maintain the order of the examination room. However, what more schools are now facing is how to prevent the increasingly rampant cheating phenomenon, because some people choose to use "black technology" to use communication equipment to cheat in the examination room. In response to this phenomenon, the examination The mobile cell phone jammer also came into being. This kind of equipment can prevent the occurrence of electronic signal cheating in the examination room in an orderly manner.

Portable jammer

Recently, many students reported that they have seen a new batch of new machines installed in the classrooms of the school, which made many people wonder what it is. In fact, it has been vigorously promoted and installed in the classrooms of the examination room. The equipment of the signal jammer is now used in the major examinations in the school, and when the college entrance examination is approaching recently, basically every examination room has been installed with this kind of equipment. This is to prevent more and more problems in recent years. The more serious the phenomenon of cheating occurs, the candidates can take exams with peace of mind in a stable and orderly examination room.

Signal jammers generally do not disturb candidates

The frequency bands of general 4G signals and WIFI signals are between 800MH and 26000MH, and the test WiFi signal blocker is a device that can effectively block all communication signals in this frequency range, so whether it is a 4G signal or a WIFI signal, It's all out of the question. And now facing the arrival of the college entrance examination, some candidates who do not focus on their studies and want to cheat by illegal means, the wifi jammer is undoubtedly a powerful tool to break their intentions, which can maintain the normal order of the examination room and allow the examination room The test takers can take the test with peace of mind, and there is no noise during the use of this equipment, which can ensure that the test process will not be disturbed by the test takers.

Many people are also very curious about how the test 4G jammer counteracts the occurrence of these cheating phenomena. In fact, based on the method of cheating by using communication equipment, no matter what method is used, it is necessary to send and receive signals in the test room. However, in the test The signal jammer cannot receive any signal in the effective shielding range, because it has the function of isolating communication signals and WIFI signals. This range is generally about 0 to 50 meters in radius, and a low-power device can just cover it. We live in one classroom, so all we can see is that each classroom has a computer installed. In fact, for schools, when buying test signal jammers, you must choose high-performance ones, because in this way, a strong shielding effect can be guaranteed and every part of the test room can be covered.
