Jamming can interfere with emergency radio communications and other vital communications. Even if it is legal in your area, it’s best not to use a jamming device in a densely populated area. [2] X Expert Source Luigi OppidoComputer & Tech Specialist Expert Interview. 30 September 2021. Don’t assume jamming devices are legal just because someone in your area is selling them. These merchants may be breaking the law.
Wi-Fi routers that follow the 802. 11b or 802. 11g standards operate at a frequency of 2. 4GHz. This is a safe bet if you can’t identify the router. Wi-Fi routers with the 802. 11a standard operate at 5GHz. The 802. 11n standard can operate at either 2. 4 or 5GHz. You may need to jam both frequencies. Some modern routers with this standard can alter their frequency automatically, which will make it much harder to jam. [3] X Research source If you don’t know the type of router being used, try downloading a program or app for viewing nearby wireless networks. Some of these will identify the frequency and channel being used, but the free versions usually do not.
The device must be broadcasting a signal. For instance, play music into a phone, or tape down the number buttons so they’re being pressed continually. Do not run a microwave with nothing inside. To improve the jamming ability of a 2. 4GHz cordless phone, expose the circuitry, then attach the antenna leads to a wire taped to a CD.

At 2. 4GHz, most routers operate on the 1, 6, and 11 channels. Use these channels as well to interfere with the other network. Nearby channels overlap with each other, causing some interference. Using channels 3, 7, and 11 will slow down almost any nearby Wi-Fi network, at least a little. At 5GHz, there are many more channels available.
Set “Channel Width” or “Bandwidth” to the largest possible range. Disable automatic channel selection. Boost power output to maximum.
5Ghz Wi-Fi signals are are particularly bad at penetrating objects.
If your kids are sneaking online when they’re supposed to be sleeping, consider turning the power level down to minimum each night. Increase it again in the morning.
To save some money, make your current antenna “directional” by placing a sheet of aluminum foil in any direction you don’t want the signal to travel.
If your router allows access to channels 12 or higher, test the highest channel. Many modern routers have the option to automatically detect low-interference channels and switch between them. Enable this option if available. Each router manufacturer arranges its own settings. If you can’t find a channel option, refer to the router manual for a guide.
Select WPA encryption, which is more difficult to hack than WEP.
