Why Does A VPN Disconnect

Firstly, the most obvious reason. Connection to a VPN can disappear very often if you have a slow internet speed. Its that simple. A weak WiFi signal will take down your VPN every single time. Just because youre connecting to a distant server, it doesnt mean your WiFi usage is redundant.

Internet connection is almost as unpredictable as the weather. But we probably know that if you take an umbrella with you, there is nothing to worry about when you go outside. In a virtual world, a VPN kill switch is your umbrella. Once you get it, youre safe.

Other common reasons include your firewall, router, or other network gateway devices settings. They might cause you a disconnection if theyre not set up correctly. Your PC protection apps, even antivirus software, can block VPN networks features, so make sure you add your VPN providers app to the exceptions list on your firewall.

An overloaded server can also be a reason. If you accidentally select a VPN server that is congested with users, that might force your connection to go off. Make sure you check its usage before connecting to it.

Finally, choose the right VPN protocol. Connections tend to be more stable when you are using a TCP protocol instead of UDP. While TCP is slower, UDP is faster but error-prone.

The Best VPNs With A Kill Switch

Weve reviewed countless VPN services over the years. And we keep revisiting the good ones so we can keep you abreast of the latest info on the best of the best. When we do this, we keep coming back to three VPNs that currently rise above all the rest. One of the many reasons we consider these the best VPNs in 2021 is because all three of them have excellent VPN kill switches.

The three VPNs we can unequivocally recommend for anyone looking for a great VPN with a great internet kill switch are:

  • NordVPN
  • Surfshark
  • ExpressVPN

So lets examine each of these VPNs in more detail and the kill switches they offer.

What If Your VPN Connection Goes Down

Why might a VPN connection suddenly drop? Maybe the VPN server you’re connected to is experiencing a lot of traffic. Or maybe you get disconnected because your internet connection is unstable.

This doesn’t happen often, but when it does then your data is no longer protected.

In another case, sometimes you might want to switch between two VPN servers. For example, if the server you’re currently connected to is slow, you may choose to connect to a new, faster server. In the few seconds between disconnecting from the old server and connecting to the new server, you could be transmitting data without encryption.

When this happens, your VPN might not be as private as you think it is.

Why Should You Use A VPN Kill Switch

Even the most reliable VPNs experience occasional drops in connectivity. And if youre relying on a VPN to keep your sensitive information secure, youll likely want an extra safety measure to protect your data in case your VPN fails. This will guarantee that youll get the level of security and privacy you want at all times.

A VPN kill switch is your last line of defense to make sure that your IP address is never uncovered. It also makes sure no one can access your unencrypted data if your VPN goes down.

Is Network Lock Automatic

What is a VPN Kill Switch? (and do you *really* need one?)

Indeed it is! Network Lock is activated by default. Your internet traffic will automatically be blocked if the VPN drops or your network is disrupted. When the VPN connection is back up, youâll be unblocked and back in action in just moments.

Windows and Mac users can turn off Network Lock in a few clicks. For Linux, it only takes a couple of commands.

How Does A Kill Switch Work

Lets get to the more complicated stuff. Hopefully, after the last part, youre pretty sure about what is VPN kill switch. Now, for those who wonder how does a kill switch work, I have an answer for you.

A VPN kill switch usually works by monitoring your connection to a VPN providers servers. It instantly sees and detects if any changes to your connection happen.

Once a connection to the network is lost, a VPN kill switch feature functions as a firewall.

If you specify any particular apps that can be vulnerable when the connection is lost, a kill switch feature terminates these apps. It disallows them to send unwanted and unprotected information to the internet.

Usually, the process of terminating the connection takes only a few seconds. After a VPN kill switch acts, it takes your device back to the previous VPN server you were attached to. That’s what most of the top VPN providers do.

Speaking about turning on the kill switch feature, most of the time, youll need to do it only once and manually through your providers application.

Its worth knowing that a kill switch feature for smartphones is required to have in California from 2015.

However, it has nothing to do with a VPN kill switch. Even most of the machinery, such as locomotives, tower cranes, or elevators, have kill switches in case an emergency happens.

How Do I Activate The Internet Kill Switch

Securing your online activities has now been made easy and simple. Heres how to enable Kill Switch in your application:

  • Step 1: Right-click on the VPN software and Run as Administrator
  • Step 2:Tap the gear to access the Settings icon in the PureVPN app
  • Step 3: Search for the Advanced Options menu

Is An Internet Kill Switch VPN Automatic

It is not always that a Kill-Switch is automatic.

To enable kill switches for most VPNs you might need to go to the app settings and enable the feature.

For instance, the IPVanish VPN allow the users to customize the Kill-Switch feature.

On top of activating and deactivating the kill-switch feature, it allows you to choose whether the connection should restored automatically and whether the VPN should change the IP periodically.

Primary Causes For Frequent Disconnections

VPN Kill Switch

Unfortunately, frequent VPN disconnections may spoil your fun a great if you cannot access your desired geo-restricted content. Therefore, you should perform some tweaks to overcome VPN disconnection issues timely.

Here is the list of major reasons that do not allow your VPN services to work properly:

  • VPN protocol selection
  • Network congestion/ poor signal strength
  • Firewall or router settings

VPN protocol selection: Surprisingly, connections seamlessly perform when the network uses the TCP protocol compared to the default UDP protocol. If your connection is unstable, there is no harm in switching the protocol.

Network congestion / poor signal strength: When numerous people use the same Wi-Fi connection to access the internet, the strength of Wi-Fi connections may decrease to a certain degree. The same goes for VPNs as well. This is because the strength of Wi-Fi connections also influences the performance of VPN services a great deal.

This is the reason a VPN connection are disconnected quite often.

Firewall or router settings: At times, firewall or antivirus software may hamper the VPN connection speeds considerably. Therefore, you should disable these features to check the performance of your VPN service. If your VPN connection become stable once you have disabled the security features, you should not apply these settings on your VPN services.

The Different Types Of VPN Kill Switch

There are different types of kill switch depending on what software you use.

On a desktop, you can have a system-wide kill switch which blocks all traffic when the VPN goes down. Or you can have an app-specific kill switch which blocks traffic only from certain programs. On a mobile app, you will need to enable the kill switch in device settings.

VPN Kill Switch Explained

A VPN Kill Switch is a feature offered by many premium VPN providers that automatically kills an internet connection if the VPN connection breaks. This is to ensure that your IP address is never exposed if the VPN falls out of use for any reason.

More advanced versions of the kill switch feature include protection against DNS leaks, which is a common mistake made with VPN connections. Having a Kill Switch is not only important for protecting your IP address, but it can also ensure that you do not accidentally expose your true location to the public or other computers on your network.

When you are connected to the internet through a VPN connection, all of your web traffic passes through an encrypted tunnel, so hackers cannot sniff out your data. If you have a kill switch enabled and the VPN connection fails for any reason, your internet connection will be shut down immediately.

Reasons For VPN Connection Fails


Even the best VPNs can disconnect from the hardware theyre concealing. These are the most common reasons:

  • VPN Account Problems First of all, make sure that youre logged into your VPN service. If youre signed out, you probably entered incorrect login details or there was some sort of glitch.

Either way, double-check your username and password. If youre still having difficulty logging into your account, check its status. Maybe its inactive because your free trial has expired or your premium license has lapsed.

  • Outdated VPN Software If the version of your VPN client is old, it wont work flawlessly. Sooner or later, an Android, iOS, Windows, macOS, or Linux kill switch will detect that somethings amiss and keep your device from using the internet.

Check for updates to ensure that you have the right iteration of the software. If you cant upgrade it from the settings, uninstall it and download the latest version.

The solution to the first is to disable filtering through your devices TCP/IP properties page. The workaround for the latter is to try a different VPN protocol.

Consider using L2TP/IPSec if youre connected through OpenVPN, or vice-versa. If PPTP is part of the selection, consider it if either of the first two fails to fix the issue.

Close the unnecessary active apps and find out whether you have some running in the background.

But if your antivirus software sees your VPN as a harmful program, it may interfere.

What Causes A VPN Connection To Drop Out

Most VPNs maintain stable, reliable connections the vast majority of the time. But unfortunately all networks experience disruption occasionally, and all it takes is for the mask to slip just once to compromise your online safety and privacy.

Here are the most common reasons for VPN kill switches to kick in and keep you covered:

  • Firewall or router settings: Your internet router or antivirus software installed on your machine may interfere with your VPN, causing the connection to drop. Checking your preferences and settings may help, but nothing beats the safety-net of a VPN kill switch.

  • Start up: If your machine starts up without an active VPN, it cant establish a secure connection. But a kill switch will still engage to prevent risky, unsecured internet connections.

  • Signal strength: Any connection is only as strong as the signal maintaining it, so weak Wi-Fi due to interference or distance from the router can disrupt your VPN connection.

  • Network congestion: Internet connections that are overburdened by heavy usage can result in ISP throttling, making your Wi-Fi connection choppy and destabilising your VPN. This is a particularly common problem on public Wi-Fi networks where youre the most exposed without a VPN.

Not All VPN Providers Offer A Kill Switch

If youre using a VPN to protect your online privacy, making sure that youre using a kill switch adds another layer of protection. Unfortunately, not every VPN provider offers this functionality.

The good news is that many do, including ExpressVPN, Private Internet Access, VyprVPN, IPVanish, and PureVPN. Most services that support the feature will be upfront about it in marketing materials, but a quick internet search should show you for sure.

Since many of the largest services now offer the feature, it isnt something that you should be paying a premium for. Its also important to understand that just because your VPN provider offers the feature, that doesnt necessarily mean that its enabled by default.
