このガイドを信頼する理由

I have run FastestVPN for six months across Windows, アンドロイド, and a home router.

Every step here comes from my own screen, not a press kit.

FastestVPN is a budget VPN that punches above its price.

Most users install the app, hit connect, and never touch the settings.

That leaves half the service unused.

This guide shows you how to use FastestVPN properly, feature by feature.

FastestVPNチュートリアル

This How to Use FastestVPN tutorial walks through setup, then every feature in the app.

最速VPN

Protect 10 devices with AES 256-bit encryption and a kill switch. FastestVPN offers a lifetime subscription plan for $40, backed by a 31-day money-back guarantee.

How to Use FastestVPN App

デバイスの互換性 lets you run the same account on nearly every device you own.

以下に、その使用方法をステップごとに説明します。

Step 1: Open the Downloads Page

Open the download page and pick your platform.

ステップ2：アプリをインストールする

Run the installer on Windows or macOS.

On Android and iOS, install the app from your store instead.

これがその様子です。

✓ チェックポイント: The FastestVPN home screen loads with a Smart Connect button.

Step 3: Set Up Devices Without Apps

Apple TV and consoles need manual configuration options instead.

A router install covers every device on your network at once.

✅ 結果: FastestVPN now runs on all your supported devices.

💡 プロのヒント: Install FastestVPN on your router first, then count it as one connection.

FastestVPNスマートトンネルの使い方

スマートトンネリング is split tunneling under a friendlier name.

以下に、その使用方法をステップごとに説明します。

ステップ1：設定を開く

Click the gear icon on the app home screen.

Scroll to the Smart Tunneling panel.

ステップ2：アプリを選択する

Toggle Smart Tunneling on and select which apps use the VPN.

Banking apps usually work better outside the tunnel.

これがその様子です。

✓ チェックポイント: Only the apps you ticked show the VPN location.

Step 3: Reconnect and Test

Save your list, then connect to any vpn server.

Check that excluded apps still show your local IP.

✅ 結果: Your traffic is split exactly the way you want it.

💡 プロのヒント: Keep your browser inside the tunnel and your printer software outside it.

How to Use FastestVPN Connectors

同時接続 lets you protect up to 10 devices on one plan.

以下に、その使用方法をステップごとに説明します。

Step 1: Log In Everywhere

Use the same username and password on each device.

There is no extra seat to buy.

Step 2: Track Active Sessions

Open your account dashboard to see what is connected.

Ten is more than CyberGhost and most VPNs allow.

これがその様子です。

✓ チェックポイント: Each device shows a connected status without kicking the others offline.

Step 3: Free Up a Slot

Disconnect an idle device if you hit the limit.

Router coverage saves slots for phones and laptops.

✅ 結果: Your whole household runs on one subscription.

💡 プロのヒント: Share the plan with family, but change the password if someone leaves.

How to Use FastestVPN DNS Leak Prevention Tool

DNSリーク防止 keeps your DNS queries inside the encrypted tunnel.

以下に、その使用方法をステップごとに説明します。

Step 1: Turn On the Setting

Open Settings and enable DNS leak protection.

It stays on across reboots.

Step 2: Connect and Test

Connect to a server, then open the leak test page on the FastestVPN site.

Run both the DNS and WebRTC checks.

これがその様子です。

✓ チェックポイント: The test page shows only FastestVPN DNS servers.

Step 3: Fix a Failed Test

Switch protocols and flush your DNS cache if a leak shows.

Retest before you trust the connection.

✅ 結果: Your browsing requests never reach your internet provider.

💡 プロのヒント: Test again after any Windows update, since updates often reset network settings.

FastestVPNライブチャットの使い方

ライブチャット connects you to customer support at any hour.

以下に、その使用方法をステップごとに説明します。

Step 1: Search First

Open the knowledge base and search your device name.

FastestVPN keeps setup guides for every supported platform there.

Step 2: Start the Chat

Click the chat bubble in the corner of the site.

Give your plan type and the exact error you see.

これがその様子です。

✓ チェックポイント: An agent replies inside the chat window within a few minutes.

Step 3: Escalate If Needed

Ask for a ticket when the fix needs engineering.

Email support is slower and less helpful in my testing.

✅ 結果: You have a fix or a ticket number in hand.

💡 プロのヒント: Screenshot the chat log before closing it, since transcripts are not always emailed.

FastestVPNのインターネットキルスイッチの使い方

インターネットキルスイッチ cuts your internet the second the tunnel fails.

以下に、その使用方法をステップごとに説明します。

Step 1: Enable the Switch

Open Settings and turn on Internet Kill Switch.

Leave auto-connect on so the app reconnects itself.

Step 2: Test the Drop

Connect, then pull your Wi-Fi for five seconds.

Your browser should stall instead of loading.

これがその様子です。

✓ チェックポイント: Pages stop loading while the VPN reconnects.

Step 3: Set Your Exceptions

Turn it off only when a captive portal blocks the login page.

Switch it back on right after.

✅ 結果: Your real IP address never shows during a dropout.

💡 プロのヒント: Pair the kill switch with auto-connect on untrusted Wi-Fi networks.

FastestVPNの複数のプロトコルを使用する方法

複数のプロトコル lets you change your vpn protocol without reinstalling anything.

以下に、その使用方法をステップごとに説明します。

Step 1: Open the Protocol List

Go to Settings and open the protocol menu.

The default is usually automatic.

Step 2: Pick the Right One

The WireGuard protocol gives the best connection speeds.

For example, OpenVPN TCP is slower but slips past strict firewalls.

これがその様子です。

FastestVPN 高度なプライバシーガイド：セキュリティ強化のためのダブルVPN + 広告ブロッカー

✓ チェックポイント: The status bar names the protocol you just picked.

Step 3: Try Double VPN

Double VPN (D-VPN) routes you through two encrypted servers.

Expect lower speed in exchange for extra cover.

✅ 結果: Your connection matches the network you are on.

💡 プロのヒント: Keep PPTP for old routers only, since it offers almost no real security.

FastestVPNのAES 256ビット暗号化の使い方

AES 256ビット暗号化 scrambles your traffic with military-grade AES 256-bit encryption.

以下に、その使用方法をステップごとに説明します。

Step 1: Confirm the Cipher

Open the app details panel and check the cipher line.

AES 256-bit is applied on every plan by default.

ステップ2：サーバーの場所を選択する

Pick a country close to you for the fastest handshake.

Distance costs more speed than encryption does.

これがその様子です。

✓ チェックポイント: The IP shown online matches your chosen server, not your city.

Step 3: Verify You Are Covered

Load any IP チェッカー site and confirm the new address.

Your provider now sees encrypted noise only.

✅ 結果: Everything you send is unreadable in transit.

💡 プロのヒント: Encryption cannot hide a logged-in Google account, so use a private window too.

FastestVPNの無制限帯域幅の使い方

無制限の帯域幅 removes data caps from every server in the network.

以下に、その使用方法をステップごとに説明します。

ステップ1：ストリーミングサーバーを選択する

Choose a country that carries the library you want.

US servers work best for Netflix catalogues.

Step 2: Start Streaming

Open the app or site and press play.

Unlimited bandwidth means no throttling mid-episode.

これがその様子です。

✓ チェックポイント: Video loads at full quality without a proxy error.

Step 3: Switch If Blocked

Some streaming sites detect and block VPN ranges.

Change servers and clear cookies to bypass the check.

✅ 結果: You can unblock streaming services without watching a data meter.

💡 プロのヒント: Wired connections beat Wi-Fi when you want the fastest streaming speeds.

FastestVPNのプロ向けヒントとショートカット

After six months of daily use, these are the tips that stuck.

キーボードショートカット

アクション	ショートカット
Show or hide the app window	Click the tray or menu bar icon
Connect to the last used server	トレイアイコンを右クリック → 接続
Open Settings on Windows	Ctrl + , (from the app window)
Quit without disconnecting	Close to tray with the X button

The desktop apps lean on the tray menu more than hotkeys.

ほとんどの人が見逃す隠れた機能

Browser add-ons: Firefox and Chrome extensions protect one browser without routing the whole machine.
Bundled extras: Some plans include a password manager and cloud storage at no extra cost.
Fire TV Stick sideloading: Enable Developer Options and allow unknown sources to install the app.
Router credentials: Log in to your router admin panel and enter the L2TP server addresses manually.

FastestVPNで避けるべきよくある間違い

Mistake #1: Leaving the protocol on automatic

❌ 間違い: Accepting the default and then complaining about connection speeds.

✅ 右: Set the WireGuard protocol manually, since it averages around 730 Mbps.

Mistake #2: Ignoring the kill switch

❌ 間違い: Torrenting or streaming with the switch off to avoid interruptions.

✅ 右: Leave it on so a dropped tunnel cannot expose your real IP address.

Mistake #3: Judging the service in one day

❌ 間違い: Cancelling after one slow server without testing others.

✅ 右: Use the 31-day money-back guarantee window to test several server locations.

FastestVPNのトラブルシューティング

Problem: Netflix shows a proxy error

原因： Streaming services blacklist known VPN IP ranges.

修理： Move to a nearby server location and switch back to WireGuard.

📌 注記： If none of these help, contact FastestVPN support through live chat.
