How to Create a WiFi QR Code for Your Home or Business

Guests at your home, customers at your café, visitors at your office — everyone needs WiFi. A QR code removes the awkward "What's the password?" moment and lets anyone connect with a single scan.

This guide shows you how to create one in under two minutes, where to put it, and how to handle the setup for a business.

What You'll Need

Before you start, find these three things:

If your router password is printed on a sticker on the router itself, that's the one to use. If you changed it since setup, you'll need to look it up in your device settings or router admin panel.

Finding your password on common devices:

• Windows — Settings → Network & Internet → your network → Show password
• Mac — Open Keychain Access, search your network name, double-click, check "Show password"
• iPhone (iOS 16+) — Settings → WiFi → tap your network name → Password
• Android — Settings → WiFi → tap your network → Share (shows a QR code you can decode instead)

Step 1 — Generate the QR Code

1. Go to WifiQRScan — Generator
2. Enter your network name exactly as it appears (case-sensitive)
3. Enter your password exactly (one typo here breaks every connection)
4. Select your security type — choose WPA/WPA2 for most home and business routers
5. If your network is hidden (not visible in the device's WiFi list), check the Hidden Network box
6. Click Generate

Your QR code appears immediately. Nothing is sent to any server — the code is built in your browser.

Step 2 — Test It Before You Print

Always scan your new QR code yourself before printing or sharing it.

1. Open your phone's Camera app (not a QR scanner app — the built-in camera)
2. Point it at the code on your screen
3. Tap the connect notification that appears
4. Confirm you join the network

If it doesn't connect, check that your password has no typos. Re-enter it and regenerate.

Step 3 — Download and Print

Once the test passes:

• Click Download PNG to save the image
• For home use, print it on a regular sheet of paper or label
• For business use, see printing options below

Print tips:

• Print at least 4 × 4 cm — smaller than that becomes hard to scan
• Use a white background with high contrast (black on white scans best)
• Laminate it if it will be in a high-humidity area like a kitchen or bathroom

Where to Put It — Home

Placement determines how often it actually gets used. Put it somewhere guests naturally look when they need WiFi:

• Living room — a small framed card on the coffee table or side table
• Guest bedroom — on the nightstand or bedside table
• Kitchen — on the refrigerator or inside a cabinet door
• Entryway — near the front door for guests who ask immediately on arrival
• Home office — on your desk for quick sharing during video calls

A small picture frame from any store works perfectly. Print the QR code, add "WiFi" as a label underneath it, and drop it in the frame.

Where to Put It — Business

For a business, a QR code that guests can actually find is part of the experience.

Café or restaurant:

• Table tents or table stickers
• Printed on the menu footer
• Framed near the register or entrance

Airbnb or short-term rental:

• Framed on the kitchen counter or bedside table
• Laminated card in the welcome packet
• Printed on a dedicated "Welcome" sheet left on the bed

Office or coworking space:

• Reception desk
• Conference room walls
• Printed on visitor badges or welcome cards

Retail or waiting room:

• Near the point of sale
• In the waiting area
• On a small tabletop display

Home vs. Business — Which Network to Use

For a home network you share with people you trust, using your main WiFi network is fine.

For a business — or even an Airbnb — use a guest network instead.

A guest network is a separate WiFi connection that runs on the same router but is isolated from your main network. Guests connected to the guest network can reach the internet but cannot see your other devices (computers, NAS, printers, smart home devices).

To set one up:

1. Log in to your router's admin panel (usually 192.168.1.1 or 192.168.0.1)
2. Find the Guest Network or Guest WiFi option (location varies by router brand)
3. Give it a simple, memorable name and password
4. Enable it and generate a QR code for it

Most modern routers support this. Check your router's manual or search "guest network" + your router model if you can't find the option.

Updating Your QR Code

If you change your WiFi password — or your router's password — you need to regenerate the QR code.

The code itself doesn't expire, but it stores the password that was active when you created it. An outdated code will scan and decode fine but the connection will fail.

Make it a habit: whenever you change your WiFi password, regenerate the QR code and replace the printed version immediately.

Troubleshooting

Phone scans the code but doesn't connect

• The password in the code doesn't match your current router password. Decode it at WifiQRScan to check what's inside, then compare with your router.

iPhone camera doesn't react to the code

• Use the built-in Camera app, not a third-party scanner.
• Check Settings → Camera → Scan QR Codes is enabled.

Android shows a connection prompt but it fails

• Your phone may not support your router's frequency band (5 GHz only). Try switching the router to broadcast 2.4 GHz as well.

QR code prints fine but doesn't scan

• The print may be too small or low resolution. Print larger and ensure the background is white with clean black modules.
