How to set up a VPN on Windows, Mac, iPhone, Android, smart TVs, games consoles and routers, how many connections you need, browser extensions vs full apps, split tunnelling, and troubleshooting common problems.
Most people have several connected devices: a phone, a laptop, perhaps a tablet, smart TV and games console. Covering them all with a VPN takes a little planning, because not every device can run a VPN app.
Count your devices
VPN subscriptions limit how many devices can connect at once, or allow unlimited connections. List the devices you'd actually use with a VPN. For most people, phones and laptops used on public Wi-Fi matter most.
Computers
- Windows and macOS: install the provider's official app from its website or the Mac App Store. Turn on the kill switch and auto-connect for untrusted networks.
- Linux: many providers offer command-line apps or WireGuard and OpenVPN configuration files.
Phones and tablets
- iPhone and iPad: install the app from the App Store and allow it to add a VPN configuration. Use the app's auto-connect or "on demand" settings.
- Android: install from Google Play. Android's settings include "Always-on VPN" and "Block connections without VPN", which act as a system-level kill switch.
Modern protocols such as WireGuard use less battery than older options.
Browser extensions
Many VPN providers offer browser extensions. These usually protect only traffic from that browser, acting like a proxy, while other apps on the device go direct. Use the full app for complete coverage.
Smart TVs and streaming sticks
Some smart TV platforms and streaming sticks, such as Android TV, Google TV and Amazon Fire TV, have VPN apps in their app stores. Many other TVs don't support VPN apps. For those, a router VPN or a provider's smart DNS feature (which changes location but doesn't encrypt traffic) may be options. Check streaming services' terms.
Games consoles
PlayStation, Xbox and Nintendo Switch don't run VPN apps. Options include:
- a VPN on your router;
- sharing a VPN connection from a computer;
- a provider's smart DNS feature, which doesn't encrypt traffic.
VPNs can add latency to online games, so connect to a nearby server.
Routers
A VPN on your router covers every device on your home network, including ones that can't run apps, and counts as one connection. But:
- many ISP-supplied routers don't support VPN client mode;
- router processors can limit speeds;
- everything goes through the VPN unless you set up exceptions;
- setup is more technical, using WireGuard or OpenVPN configuration files.
Some people use a second router just for VPN devices.
Split tunnelling
Split tunnelling lets you choose which apps or sites use the VPN. It's useful for banking apps, local network printers, and services that block VPNs, while keeping the rest protected. Availability varies by device and provider.
Troubleshooting
- Can't connect: try another server or protocol, check the date and time on your device, and restart the app.
- Slow speeds: choose a nearby server and try WireGuard.
- Apps not working: use split tunnelling for that app.
- Too many devices: log out of old devices in your account dashboard.
- Local devices disappear: enable "allow LAN" or local network access in the app's settings.
Security tips
- Only install official apps from the provider or official app stores.
- Use two-factor authentication on your VPN account.
- Keep router firmware updated if you use a router VPN.
Frequently asked questions
Does a router VPN protect me on public Wi-Fi?
No. It only covers devices on your home network, so use the app when you're out.
Can I use one subscription for my family?
Usually yes, within the connection limit, but check the provider's terms.
