How does a deauthentication attack, often facilitated by Kali Linux tools, impact a Wi-Fi network?

A deauthentication attack works by sending spoofed management frames to connected Wi-Fi clients and the access point, tricking them into thinking they need to disconnect. This forces clients to drop their connections. By repeatedly sending these frames, an attacker can prevent legitimate users from connecting or staying connected to the Wi-Fi network, effectively causing a denial of service.
