What frequency bands does WiFi have? I want to buy a jammer to block the WiFi signal at home

Wifi jammers are one of the most common jamming devices on the market for all wireless signals in the WiFi frequency range (2.4-2.5 GHz). They can successfully intercept these signals and are designed to help people solve problems caused by mobile phone connections. Every signal jammer can operate in a specific frequency range, and wifi jammers are no exception. To prevent unauthorized persons from "leaving" confidential information, great care must be taken when using jammers.
