Stadiums, airports, and fan parks are some of the worst environments imaginable for public Wi-Fi. Tens of thousands of people competing for the same signal means packet loss, crawling speeds, and connections that drop without warning. So, for example, if you're heading to a few games at the FIFA World Cup 2026, things might not be as smooth as you'd like.
One of the best VPNs is a handy tool to have at your disposal on networks like these. While it's fairly unlikely nowadays you'll be caught out by a man-in-the-middle attack, boosting your privacy can only be a good thing – and when a VPN is set up right, a VPN may also be able to increase your connection speeds significantly.
Here, I'll run down a few quick settings to tweak to make your public Wi-Fi experience more bearable.
Pick your protocol
A VPN protocol is the set of rules that determines how your device encrypts and moves your data. On a congested or restrictive network, the wrong protocol can mean failed connections, throttled speeds, or both – and switching is often the quickest fix.
WireGuard should be your first port of call. It's a modern protocol built with a low data overhead and near-instant reconnection times, making it well suited to the kind of unstable connections you'll find in a packed stadium or airport terminal. Most VPN apps already default to it – but if you're on an iPhone, check your settings, as IKEv2 is often the default instead.
IKEv2 is a solid runner-up for mobile users who switch frequently between Wi-Fi and cellular data. It handles network changes smoothly, though speeds won't quite match WireGuard.
If you're struggling to connect at all, try OpenVPN. It's generally slower than WireGuard, but its ability to run on port 443 – the same port used by standard web traffic – means it's more likely to work on networks that try to block VPNs. For a deeper look at how the fastest VPNs handle different conditions, our dedicated guide is worth a read.
Stay stealthy
Many stadiums and airports actively manage their networks by throttling heavy data users – a necessary measure when tens of thousands of people are sharing the same connection, but one that can reduce your speeds to near-unusable levels during a big event.
VPNs can sidestep this by hiding your traffic from the network – if it can't see what you're doing, it can't single you out for throttling. The catch is that many venues have wised up to this, and will throttle any traffic that looks like VPN traffic too.
The fix is Stealth Mode – sometimes called Obfuscation or Scramble depending on which app you're using. It disguises your VPN traffic as ordinary web traffic, so the network treats it accordingly. You keep the speed benefits of bypassing throttling while your actual activity stays hidden.
Unfortunately, if the network you're connected to flat-out throttle's everyone's connection, regardless of how much data theyre using, a VPN won't make much of a difference. As always, there's an element of trial and error to this.
Set switches to kill
Switching between Wi-Fi and mobile data – or simply dropping out of range in a crowded venue – can cause your VPN connection to drop momentarily. That split second is enough for your real IP address to be exposed before the VPN reconnects, which defeats the purpose of using one in the first place.
A kill switch solves this by blocking all internet traffic the moment your VPN drops, preventing any leaks until the connection is restored. Pair this with Auto-Connect, which ensures your VPN engages automatically whenever you join an untrusted public network, and you've closed off the two most common sources of accidental exposure.
As a side-note, your VPN "blocking all internet traffic" sounds drastic, but in reality, it's nothing to worry about. This only equates to a second or two of downtime, which is very unlikely to be noticed.
Split the tunnel
Running all your apps through a VPN simultaneously puts extra demand on both your device and the network – bandwidth you can't afford to waste when thousands of people are competing for the same signal.
Split tunneling lets you choose which apps use the VPN and which don't. Route your sensitive apps – banking, email, social media logins – through the encrypted tunnel, and let everything else connect directly. Checking live scores or streaming music in the background doesn't need VPN protection, and bypassing it for those apps can free up enough speed to make a real difference. Plus, by reducing the amount of data you need to encrypt will also save you precious battery life.
Bottom line
A few seconds spent in your VPN's settings can be the difference between a working connection and a frustrating one.
Switch your protocol – WireGuard for speed, OpenVPN if you're struggling to connect – enable Stealth mode, turn on your kill switch, and set up split tunneling. Do all of this, and you'll be in a far better position than the thousands of other people on the same network.
What to look for in your app | What to set it to | What it does for you |
|---|---|---|
Protocol / Connection Type | WireGuard / OpenVPN | Generally gives you the fastest speed and quickest reconnections. If you have connection issues, try OpenVPN. |
Stealth / Obfuscation | ON (if you struggle to connect) | Not always necessary, but helps stop the venue's Wi-Fi from blocking your VPN. |
Kill Switch | ON (always) | Keeps you safe if the crowded Wi-Fi suddenly drops. |
Split Tunneling | Enabled (Select apps) | Saves speed by only protecting your most important apps. |
