• Meta Platforms owns WhatsApp, an internationally available freemium, cross-platform centralised instant messaging (IM) and voice-over-IP (VoIP) service. Users can exchange text and voice messages, make audio and video chats, and share photographs, documents, user locations, and other stuff through the app.
• Because different routers have different settings and menus, there is no definite solution to disable WhatsApp on wifi.

• To restrict WhatsApp on wifi, go to your router's settings and add the name of the website or application to the blocked list.
