Why does my VPN keep disconnecting?

The most common reason for VPN disconnection is your Wifi network. If you are connecting to the internet via Wifi, and then connecting your VPN, you’re likely to experience drop-outs. This is because Wifi isn’t continuous. It may appear to...

FAQ · Troubleshooting VPN Disconnections

A VPN keeps disconnecting most often because it is running over an unstable wifi network rather than a wired connection — wifi appears continuous but briefly drops out for a split second regularly, and that is enough to break a VPN session even though it goes unnoticed during ordinary browsing.

Diagnosing the cause

Check the connection type: if you are on wifi rather than a wired ethernet connection, this is very likely the cause.
Check distance and interference: weak signal, thick walls, or interference from other devices increases how often wifi drops occur.
Rule out the VPN software itself by testing on a wired connection — if disconnections stop, the wifi network was the cause.

How to fix it

If your PC is close enough to your home modem or router, connect them directly with a network cable rather than relying on wifi. This provides internet access via a stable wired connection instead of wifi, and VPN connections become substantially more reliable as a result. Where a wired connection is genuinely not possible, positioning the device as close to the router as possible and reducing interference from other wifi devices helps, though it will not fully eliminate the issue.

Frequently asked questions

I've restarted the VPN client many times and it still disconnects — what next?

Restarting the client does not address the underlying wifi instability causing the drops; test with a wired connection to confirm the cause before assuming the VPN software itself is faulty.

Does the office end of the VPN connection matter too?

Yes, though home wifi instability is by far the more common cause; if a wired home connection does not resolve the issue, the office-side VPN configuration should be checked next.

Yes, Fresh Mango Technologies can advise on and help configure a stable wired home working setup, including VPN configuration, as part of remote working support.

The most common reason for VPN disconnection is your Wifi network. If you are connecting to the internet via Wifi, and then connecting your VPN, you're likely to experience drop-outs. This is because Wifi isn't continuous. It may appear to be, but occasionally it will drop out - just for a split-second. That split-second is enough to drop your VPN connection. How can you ensure VPN continuity? If your PC is close enough to your modem/router, then connect them both with a network cable. This will provide internet via cable, not wifi, and your VPN connection will be much more robust.
