How to Create a Wi-Fi QR Code and Connect by Scan
A Wi-Fi QR code helps guests join a wireless network without manually typing a long password. It is useful in homes, offices, cafés, hotels, waiting rooms and rental properties. On supported phones, scanning displays a prompt to join the network.
Information required
You need the Wi-Fi network name, also called the SSID, its password and the security type. Common choices include WPA/WPA2/WPA3, WEP and no password. The network name and password are case-sensitive, so uppercase letters, spaces and symbols must be entered exactly.
Steps to generate the code
Open the AeroQR Wi-Fi generator, enter the exact network name, select the security type and enter the password. Mark the network as hidden only if it does not broadcast its name. Generate the code and test it with Android and iPhone devices when possible.
Where to display it
Place the code where authorized guests can see it, such as reception, a meeting room or a welcome card. Do not publish a private network password on a public webpage. Businesses should consider a separate guest network so visitors do not join the network used by staff devices and internal systems.
When network details change
A static Wi-Fi QR code contains the details entered when it was created. If the network name, password or security setting changes, create and print a new code. Remove old copies so guests do not try outdated credentials.
Troubleshooting
If scanning does not connect, compare every character with the router settings. Confirm the security option, check that the network is in range and make sure the phone supports Wi-Fi QR joining. A router device limit or access rule may also block a new connection.
Frequently asked questions
Does the code show my password?
The password is encoded inside the code and may be readable with suitable tools, so share it only with users you trust.
Can it work with a hidden network?
Yes. Select the hidden-network option and enter all details accurately.
Will it work without internet access?
The code can provide local Wi-Fi credentials, but internet access depends on the network.
Should a business use its main network?
A separate, restricted guest network is safer and easier to manage.
Quick checklist
- Copy the SSID exactly.
- Choose the correct security type.
- Check capitalization and symbols in the password.
- Use a guest network for visitors.
