5 Mistakes People Make After Buying a VPN

So you just bought a VPN. Good move. But here's something most people don't realize — purchasing a VPN subscription is only half the battle. The way you use it matters just as much as having it in the first place. And honestly, a lot of people set it up, assume they're protected, and then unknowingly leave huge gaps in their privacy.

I've seen this happen a lot. Someone buys a VPN thinking it's a magic shield, never touches the settings, and wonders why their experience feels exactly the same as before. The good news is that these mistakes are easy to fix once you know what to look for. Let's walk through the five biggest ones.

Why Getting Setup Right Actually Matters

A VPN works by routing your internet traffic through an encrypted tunnel, masking your IP address and making it harder for third parties — your ISP, advertisers, hackers on public Wi-Fi — to spy on what you're doing online. But that protection only works when everything is configured properly. Think of it like buying a deadbolt for your front door and then never actually locking it. The tool is there, but you're not getting the benefit.

According to the Electronic Frontier Foundation, privacy tools are only effective when users understand how to use them correctly. That's not a knock on regular people — VPN apps can be surprisingly confusing, and the defaults aren't always set up in your best interest.

Now let's get into the actual mistakes.

Mistake 1 — Ignoring the Kill Switch Setting

This is probably the most common mistake, and it's a big one. A VPN kill switch is a feature that automatically cuts your internet connection if your VPN drops unexpectedly. Without it, your device will just reconnect to the internet normally — exposing your real IP address without you even noticing.

VPN connections drop sometimes. It happens due to server issues, network changes, switching between Wi-Fi and mobile data, or just random hiccups. If your kill switch isn't enabled, that brief moment of disconnection is enough to leak your real location and identity to whatever site or service you're using.

Here's the thing — most VPN apps have a kill switch, but it's often disabled by default. You have to go into the settings and turn it on manually. It takes about thirty seconds, and it makes a massive difference. Seriously, go check right now if you haven't already.

Mistake 2 — Always Connecting to the Nearest Server

This one is a bit counterintuitive. Your nearest server will usually give you the fastest speeds, which is great for general browsing. But blindly defaulting to the closest server every single time means you're missing out on a lot of what a VPN can actually do.

Say you want to access content that's only available in another country, or you're trying to avoid geo-restrictions on a streaming platform. Connecting to a server in the same country you're already in won't help with that. And if you're traveling abroad and want to access services from back home, you'd actually want to connect to a server in your home country.

Beyond streaming, there are also privacy reasons to mix up your server choice. Always connecting to the same server creates a more predictable pattern. Rotating between servers occasionally — especially if you're privacy-conscious — adds an extra layer of unpredictability to your traffic. It's not something most casual users need to worry about, but it's worth knowing.

The bottom line here is to be intentional about which server you pick. Don't just hit "Quick Connect" every time and forget about it.

Mistake 3 — Not Checking for DNS Leaks

This one trips up even people who are pretty tech-savvy. A DNS leak happens when your DNS requests — basically the queries your device makes to look up websites — are sent outside the VPN tunnel, often directly to your ISP's DNS servers. That means your ISP can still see which websites you're visiting, even though you're connected to a VPN.

It sounds technical, but the fix is simple. Most reputable VPNs handle DNS internally to prevent leaks, but you should verify this yourself. There are free tools online like dnsleaktest.com where you can run a quick check. Connect to your VPN, visit the site, and run the extended test. If the results show your ISP's DNS servers instead of your VPN provider's, you've got a leak.

If you do find a leak, the first step is to check your VPN app's settings for a "DNS leak protection" option and make sure it's enabled. If the problem persists, it might be worth switching to a VPN that handles this more reliably. According to research from Princeton University's computer science department, DNS leaks are more common than most users realize, and they can completely undermine the privacy you're trying to achieve.

Running a DNS leak test takes about two minutes and should honestly be the first thing you do after setting up any VPN.

Mistake 4 — Assuming a VPN Makes You Completely Anonymous

This is a mindset mistake more than a settings mistake, but it might actually be the most dangerous one on this list. A VPN does a lot of great things — it hides your IP address, encrypts your traffic, and makes it harder for your ISP to snoop on your activity. But it does not make you invisible on the internet.

Here's the thing — if you're logged into your Google account while using a VPN, Google still knows who you are. If you're posting on social media, those platforms still have your account information. If you've accepted cookies on websites, trackers can still follow you around. A VPN masks your IP address, but it doesn't erase your digital identity.

There's also the question of what your VPN provider itself can see. If a VPN keeps logs of your activity, that data could potentially be accessed by authorities or leaked in a breach. This is why choosing a VPN with a verified, independently audited no-logs policy matters so much. Not all VPNs are equal on this front.

I think a lot of people buy a VPN and then start doing things online they wouldn't normally do, assuming they're completely anonymous. That's a risky assumption. A VPN is a powerful privacy tool, but it works best as part of a broader approach to online privacy — not as a standalone solution.

Mistake 5 — Never Updating the App or Checking Protocol Settings

This last one sounds boring, but it genuinely matters. VPN apps get updates for a reason — security patches, bug fixes, performance improvements, and new features. If you installed your VPN app six months ago and haven't updated it since, you might be running outdated software with known vulnerabilities.

Most apps update automatically, but it's worth checking occasionally, especially if you notice your VPN behaving strangely or your speeds feeling sluggish.

On top of that, take a look at your VPN protocol settings. The protocol is basically the method your VPN uses to create and maintain the encrypted tunnel. Older protocols like PPTP are outdated and considered insecure. Modern options like WireGuard or NordLynx (which is NordVPN's implementation built on WireGuard) offer much better speed and security. If your app is defaulting to an older protocol, switching to a modern one can make a noticeable difference in both performance and protection.

According to the official WireGuard documentation, the protocol is designed to be faster and leaner than older options like OpenVPN, while maintaining strong cryptographic standards. Most top-tier VPNs now support it, so there's really no reason to stick with outdated protocols.

Common Questions About VPN Mistakes

Does turning on a VPN automatically protect me from everything?

Not quite. A VPN protects your IP address and encrypts your traffic, but it doesn't block malware, prevent phishing attacks, or stop you from being tracked through cookies or account logins. It's one layer of protection, not a complete security solution on its own.

How do I know if my VPN kill switch is working?

The easiest way is to connect to your VPN, find out your current IP address (just Google "what is my IP"), then manually disconnect the VPN while keeping your browser open. If the kill switch is working, your internet should cut out immediately. If you can still browse normally, the kill switch isn't active and you should check your settings.

Is it safe to use the free version of a VPN?

This is tricky. Some free VPNs are legitimate but limited versions of paid products. Others — and there are a lot of them — make money by logging and selling your data, which is literally the opposite of what you want from a privacy tool. I'd personally be very cautious about free VPNs from unknown providers. If cost is a concern, look for a reputable paid VPN with a money-back guarantee so you can try it risk-free.

How often should I switch VPN servers?

For most people, there's no strict rule here. Connect to whichever server makes sense for what you're doing — closest server for general speed, specific country for geo-restricted content. If you're more privacy-focused, rotating servers occasionally is a reasonable habit, but it's not something the average user needs to stress about daily.

Bottom Line

Buying a VPN is a smart move for your online privacy, but it's not a "set it and forget it" situation. The five mistakes above — skipping the kill switch, defaulting to the same server, ignoring DNS leaks, overestimating anonymity, and never updating the app — are all easy to avoid once you know about them. Take fifteen minutes to go through your VPN settings after reading this, and you'll be in a much better position than most people who just hit "connect" and hope for the best.

If you're still looking for a reliable VPN or thinking about switching, VPNTierLists.com consistently rates NordVPN at the top for its combination of speed, security features, and a genuinely verified no-logs policy. It's the one I'd recommend to most people without hesitation.
