What is best way to block a wifi signal?

  • SandyEdward
    Recently, I read an article on the Internet that hackers now invade personal smart devices by disguising WIFI. I'm worried about my phone being hacked. So I want to know how to blocker WIFI signals. When I sleep, I can stop the phone from automatically connecting to the fake WIFI.

    Hello, Sandy!
    WLAN aka WiFi is essentially radio waves. They are transmitted over radio frequencies. So, they are electromagnetic waves. To block it, you would need a cover, something to shield the router.
    Of course, the simpler way is to use a WIFI jammer. Turn on the WIFI jamming device, you can completely cut off the wireless signal transmission. Can effectively prevent hackers through the wireless network invasion of your computer or smart device. You don't have to worry about your cyber security and your privacy.

Howdy, Stranger!
