How to Block the WiFi Network?
To disrupt the wireless network, you must send interference signals at the same frequency and strength as the routers. The easiest way is using a jammer, but that’s not possible in some countries because the legal reason. For more information, you can find it on Brouilleurdonde.com.
WiFi jammer, does it works?
Short answer – Yes. WiFi jammer works like a charm. But you have to ensure these kinds of devices are legal to be used in your country.
Jammer is a signal generator that can transmit interference radio waves to disrupt the target frequency. For example, a mobile phone jammer (Brouilleur Telephone) can prevent your phone from connecting with the cell tower, so no one can call or send you a message. WiFi jammer working in the same way. It will send a noise signal to disable the routers, so all smart devices connected to that router will lose internet access.
WiFi jammers may interfere with emergency radio communications and other vital communications. It is best to avoid using a WiFi jammer in densely populated areas, even if it’s legal.
Decide the frequency at which it should be jammed
If WiFi jammers are banned in your area, you will need to use a more targeted approach. Each wireless device transmits signals at one frequency. You will need to respond on the same signal to drown it out. Use this frequency guide to find the name of the device you wish to jam.
You can still identify by their standard if you don’t know which frequency your routers are working on. In most cases, WiFi routers that use 802.11b and 802.11g standards work on the 2.4GHz frequency. The 802.11a routers operate 5.0 GHz.
The 802.11n standard is compatible with both 2.4 and 5.0GHz. It is possible to jam these frequencies. Modern routers that use this standard can automatically change the frequency of their frequencies, making them harder to jam.
You can download an app to see nearby wireless networks if you don’t know which type of router it is. While some programs can determine the channel and frequency, others don’t.
Switch on a device at the same frequency
A microwave, another cordless phone, or another wireless device can be used to block a 2.4GHz wireless signal. The device must be able to interfere with the nearby 2.4 GHz network as long as it is 2.4 GHz. It can cause a slight slowing or complete loss of signal. Unfortunately, it is not possible to predict what the effect will be.
The device must transmit a signal. You can play music on your phone or tap the number buttons to ensure they are always pressed.
You can increase the jamming power of a cordless phone at 2.4 GHz by getting your hands dirty and connecting the antenna cables to a wire taped to a CD. If jamming is prohibited, it may be illegal.
Modify router
You can modify your router to gain more control over interference. You can adjust your router’s settings to create intentional interference if it is operating on the same frequency. First, access your router settings. Start an Internet browser. Type your router’s address into the URL address field. These are the most popular options until you reach the settings page for your router.
- http://192.168.0.1
- http://192.168.1.1
- http://192.168.2.1
- http://192.168.11.1
If none of these options work, try searching the internet for the IP address on your router model or looking in the network settings or WiFi list on your mobile.
Before you can access the settings, you may need to authenticate. If you are unsure of the password, consult your router’s manual.
Select the transmission channel. The router cannot use all frequencies simultaneously. The frequency band can be divided into 14 channels in the 2.4GHz band and 23 in the 5.0 GHz band. You may not be able to access all channels depending on your router. Or, you may have limited options for changing the configuration. Use as many channels possible as you can. You can only use one or two channels at once, so switch from one channel to the next and check to see if there is a decrease in signal strength.
Most routers at 2.4 GHz operate on channels 1 through 6. These channels can be used to interfere with other networks.
Interference can be caused by neighboring canals being nearby. You can slow down most WiFi networks by using channels 7, 11, and 11. Many more channels are available at 5.0 GHz.
