Wireless jamming devices are tools that help block your Wi-Fi and any other wireless signals. You can buy them online or in stores, depending on the type of jammer you're buying. There are several types of wifi jammer: Portable Wi-Fi Signal Jammers, Mobile Signal Jammers, and Wi-Fi Repeaters/Amplifiers.
Here is my go-to wifi jammer:
EO12001US - This is a powerful little device that blocks all types of signals, including cell phones, tablets and WiFi devices. It's small and portable so you can take it with you for a quick fix at the office or at home when you need it! It's definitely one of the most expensive options out there, but if you're looking for something that works on its own (no messy wires) and is easy to carry around, it's worth every penny!
Buy a WiFi Blocker
Because some WiFi routers have more advanced features, you'll need to review your router's settings before buying a wifi frequency jammer. Basic router models may only have one or two settings to choose from, while others may give you more control.
The basic rule is to buy a WiFi signal jammer that can interfere with the exact frequency your WiFi router uses to communicate with your device. To do this, you need to check exactly which channels your router is capable of, and then buy a jammer that can interfere with at least one of them.
For example, if you can manually set your WiFi router to only operate in the 2.4GHz range, buying a basic jammer that only blocks the 2.4Ghz range will do. If you can't control your WiFi router's channels, you'll have to buy a more advanced WiFi blocker.
Decide what kind of equipment you want and choose the best wireless shield for your budget. Consider the size of your room, house or apartment and how much equipment you need to shield. The best wifi blockers are the ones that meet your specific needs. If you are looking for a device that can block Wi-Fi in your hotel, office or school, I recommend you to buy this wifi jammer device.
