Why a VPN connection drops
A tunnel can break for everyday reasons. The Wi-Fi signal gets weak, a laptop wakes up from sleep, a phone moves from home Wi-Fi to mobile data, or you switch to another server.
Some networks also cut VPN traffic on purpose. Hotel, office and campus Wi-Fi do this more often than home networks.
What happens with and without it
Without a kill switch, the operating system quietly sends traffic over your normal connection as soon as the tunnel is gone. Background apps such as cloud sync or an open browser tab keep talking to the internet with your real IP address, often before you notice anything.
With the kill switch on, VPN Club blocks internet access on the device the moment the tunnel breaks. Those requests fail instead of leaving unprotected. When VPN Club reconnects, traffic moves through the tunnel again.
Signs that it is working
If pages suddenly stop loading and the app says you are disconnected, the kill switch is doing its job. VPN Club keeps trying to reconnect, and you can also pick a different server yourself.
To use your normal connection, press Disconnect in the app. A disconnect you choose lifts the block right away. The block only stays when the tunnel drops on its own.
Where to switch it on
Every VPN Club plan has the kill switch, Basic included. On desktop it is one toggle in the app settings.
Android has its own always-on VPN option, and it works best when you turn it on next to the app setting. If you run VPN Club on a router with a WireGuard configuration file, the behavior depends on the router firmware, so look in the router settings.
- Windows, macOS, Linux: Settings > Connection > Kill switch
- Android: Settings > Connection > Kill switch in the app, then in the phone's VPN settings turn on Always-on VPN and Block connections without VPN for VPN Club
- iOS: Settings > Connection > Kill switch
