VPN Keeps Disconnecting
What's happening
Your VPN keeps disconnecting. You reconnect. It drops again.
It's been happening for days or weeks. Nothing you try fixes it.
You can't rely on it anymore. Every drop breaks something.
It's fine when you're sitting still. It drops when you switch from Wi-Fi to mobile data, or move between networks.
What people assume
Most people assume the VPN is broken or unreliable. Most people assume the VPN is broken or unreliable. Often it's the network — not the VPN. Mobile networks, hotel Wi-Fi, and networks with aggressive timeouts create conditions that make maintaining a persistent tunnel difficult for any provider.
Most people assume reconnecting fixes the problem. It fixes the symptom. If the underlying condition — an unstable network, a protocol mismatch, a timeout setting — doesn't change, the VPN will disconnect again.
Most people assume all disconnections are the same. A VPN dropping because the network changed is different from a VPN dropping mid-session on a stable connection. The pattern of when it happens is more useful than the fact that it happens.
What's actually going on
A VPN is a persistent tunnel over a network that isn't persistent. Every time the underlying connection shifts — a network switch, a timeout, a packet loss spike — the tunnel has to recover.
How well it recovers depends on the protocol, the provider's infrastructure, and what the network is doing. Disconnections aren't failures — they're a stress test the VPN either passes or doesn't.
Where this leads
If disconnections happen during work — sessions drop mid-call, tools lose connection, reconnecting takes long enough to matter — that's a reliability problem with real consequences. See how session reliability works in work contexts
If disconnections happen when switching networks — moving from Wi-Fi to mobile data, changing locations — the problem is how the VPN handles network transitions, not steady-state performance. See how network switching affects VPN stability
If disconnections are followed by a spike in lag or a slow reconnect — timing matters and every interruption costs something — that's a latency-adjacent problem. See how reconnection overhead works
If the pattern is general instability without a clear trigger — just drops, at random, on any network — that's a broader reliability question. See how VPN stability breaks down as a conflict
No guarantees
No VPN maintains a connection through every network condition. Aggressive NAT, packet filtering, and network timeouts can interrupt any tunnel.
Kill switch behavior matters here. If the VPN drops and traffic continues unprotected before reconnection, the interval of exposure is real — however brief.
Switching providers doesn't fix disconnections caused by network conditions. The network is the variable, not the software.
