Kill switch: the safety lever for dropped tunnels

Most tunnel failures last only a moment, and you rarely notice them. Your device does, though. It quietly reaches for the ordinary connection, and every app running in the background goes out with your real IP. Our kill switch shuts that door: no tunnel, no traffic, until the CoxVPN connection is back.

What can leak in a three second gap?

More than you would guess. Messengers ping their servers to stay reachable. Cloud drives upload the photo you just took. Weather and news widgets refresh on their own schedule.

Each of those requests carries an IP. If the tunnel is down and nothing stops them, that IP belongs to your home line or your carrier. With the switch on, they wait in line and leave through CoxVPN a few seconds later.

When does the tunnel usually drop?

Everyday moves cause most of it. Your phone hands off from mobile data to home Wi-Fi as you get in. A laptop wakes up after a night in sleep mode. You ride a subway car between stations with a weak signal. You pick a new city on the server screen.

Networks can force it too. Some campus and hotel networks reset long encrypted connections every so often.

Where will I find the switch?

It is part of Basic, Plus and Pro at no added cost. Our apps are still being prepared, and the switch will live in their connection settings.

On Android, the system adds a second guard. In system settings, set CoxVPN as the always-on VPN and turn on the option that blocks connections without it. Routers are different. If yours runs our WireGuard profile, its own firmware sets the drop behavior, so look there.

  • Windows, Mac and Apple mobile devices: open Settings, go to Connection, flip Kill switch
  • Android: our switch first, and in system settings mark CoxVPN as Always-on VPN with Block connections without VPN
  • Router: the WireGuard section of your firmware

How do I get traffic moving again?

During a block, pages spin and the app reports that it is reconnecting. Usually it comes back on its own. If it takes too long, tap a different server.

Pressing Disconnect yourself releases everything at once. Holding only applies to drops you did not ask for.

Common questions

Is the kill switch an add-on for Basic?

No. It comes with Basic, Plus and Pro, and the price of the pass already covers it.

The sign-in page for hotel Wi-Fi never opens. Why?

Before the VPN connects, the kill switch can hold that page back. Disconnect, accept the hotel's terms, and connect CoxVPN again.

Will I notice it in my speeds?

No. As long as the tunnel is healthy, the switch just sits and watches. It only acts once the tunnel is gone.
