Most users install it, hit connect, and never touch the rest.

This step by step guide shows you how to use ProtonVPN properly.

Setup first, then every feature worth knowing.

ProtonVPN Pro Tips and Shortcuts

After two years with ProtonVPN, these are the shortcuts I actually use.

キーボードショートカット

ほとんどの人が見逃す隠れた機能

• スプリットトンネリング: Send your banking app outside the vpn tunnel while everything else stays protected.
• Stealth protocol: Disguises VPN traffic as normal HTTPS so ホテル and campus Wi-Fi stops blocking it.
• Router install: Put ProtonVPN on a compatible router and every device on the network is covered, including Android TV.
• Profiles tab: Save a country plus protocol combination and reconnect to it in one click.
• Browser extension: The Chrome and Firefox browser extensions protect web traffic without routing your whole device.
• Always on VPN: On Android, this setting will block connections that try to reach the internet outside the tunnel.

ProtonVPN Common Mistakes to Avoid

Mistake #1: Assuming the Kill Switch Is On

Mistake #2: Always Picking the Farthest Server

Mistake #3: Running an Outdated App

ProtonVPN Troubleshooting

Problem: The VPN Connection Keeps Dropping

原因： An overloaded vpn server or an unstable Wi-Fi link.

修理： Switch to a server at least 10 numbers away from the current one, then reconnect.

Problem: A Website Says You Are Blocked

原因： The site recognises the exit IP as a shared VPN address.

修理： Try another vpn server in the same country, or switch to the Stealth protocol.

Problem: Slow Downloads and Upload Speeds

原因： A distant server, high server load, or an older protocol.

修理： Switch to WireGuard, check the server load figure, and confirm VPN Accelerator is enabled.

📌 注記： If none of these fix it, paid users get live chat and everyone can use the Proton VPN Help and support page.
