Wi-Fi QR Code Generator
Create a guest Wi-Fi QR code so visitors can join without typing a long network name or password. This is useful for cafes, offices, rental properties, salons, clinics, and event venues.

What to include
- Network name exactly as it appears on devices.
- Password with correct capitalization and symbols.
- Security type, usually WPA for modern routers.
- A short printed note such as "Scan to join guest Wi-Fi."
Set up a guest network before making the sign
A QR code does not add security to the network. It only packages the same credentials that a guest could type manually. When possible, create a separate guest network with client isolation and a password that can be changed without affecting staff devices, printers, or smart equipment.
Copy the network name from a device that is already connected instead of relying on memory. Network names and passwords are case-sensitive, and leading or trailing spaces are easy to miss. If the router broadcasts separate 2.4 GHz and 5 GHz names, encode the network most visitor devices can reach reliably in the intended area.
Choose the correct security setting
| Network setup | Generator choice | Check before printing |
|---|---|---|
| WPA2 or WPA3 personal | WPA | Confirm a phone can join using the same password manually. |
| Open guest network | None | Confirm whether a browser sign-in page appears after joining. |
| Hidden network | Use the hidden-network option when available | Test on Android and iPhone because support can differ. |
| Enterprise login | A basic Wi-Fi QR may not be sufficient | Enterprise networks can require identity, certificates, or device management. |
Print tips
Use a high-contrast QR code, print it at least 1.6 inches wide for table signs, and test the final sign from the distance guests will actually scan it.
Wi-Fi QR code troubleshooting
If a phone cannot join after scanning, check the network name first. Wi-Fi QR codes are case-sensitive, so a hidden space, wrong capitalization, or old password can break the scan even when the QR code itself is readable.
- The camera reads the code but does not join: verify the security type and try the credentials manually.
- The phone joins but has no internet: complete any captive-portal sign-in and check router access rules.
- Only some phones connect: confirm the network band, hidden-network support, and device compatibility.
- An old sign still works: replace every printed copy after changing the guest password.
Privacy and placement
Anyone who can photograph the sign can recover the credentials later. Place employee and private-network details out of public view, and use a guest network for reception areas, rentals, waiting rooms, and events. Print the network name below the code so staff can confirm which sign belongs to which location.
