WiFi QR code scanner
If the QR already exists, start with the receiving phone's built-in QR tools. The job here is scanning and joining—not generating another code.
RepointQR creates WiFi QR codes; scanning happens on the receiving device. Only create a replacement when the existing code is unreadable or its network details are no longer current.
Change WiFi name or password after printing
No reprint needed.
Scanner-first, not generator-first
Use the QR-reading feature already available on the receiving phone before reaching for a separate generator.
A successful scan is only step one
The QR can decode correctly while the network still rejects an old password or requires another access step.
Treat reading the code and joining the network as two separate checkpoints.
If the phone cannot read the QR, work on camera, focus, lighting, or the image. If it reads the QR but cannot join, investigate the network instead.
Use the QR tools already built into the receiving device when they support the job. For example, Apple documents QR scanning with Camera or Code Scanner, while Google documents Camera and Quick Settings scanning on Pixel phones.
Create a new code only after confirming that the old one is damaged, outdated, or based on credentials that have changed.

Workflow
Keep the code-reading step distinct from the network-joining step.
Use the receiving device's current QR-reading path. On iPhone, Apple documents Camera and Code Scanner. On Pixel, Google documents Camera and a Quick Settings QR scanner. Other Android phones can expose a different path.
Before accepting the resulting action, make sure the network name or connection prompt matches the WiFi you expected to join.
Check whether the password changed, the network is reachable, or an additional guest portal or policy is required. Repeatedly rescanning the same stale QR will not repair the underlying network access.
The searcher already has a code and wants a reliable path from scan to connection.
A guest at a home, office, café, or venue wants to scan the posted WiFi QR rather than type the credentials.
The QR appears on a sign, but users report either scan problems or failed joins and the host needs to identify which layer is broken.
Comparison
This distinction prevents a working QR image from being blamed for a WiFi configuration issue.
Check image quality, focus, lighting, cropping, viewing distance, or whether the device has an appropriate QR-reading path.
The encoded credentials may be stale, the network may be unavailable, or another access requirement may exist after association.
Common questions when the code already exists.
No. This page explains the scanning workflow. Use the receiving device's built-in QR tools; use RepointQR only when you need to create a replacement code.
Not automatically. Start with the QR capabilities already provided by the phone or operating system, then consider another tool only if the built-in path cannot perform the required job.
The QR may contain an outdated password, the network may be unavailable, or the network may require another access step. Decoding the QR and successfully joining WiFi are different checkpoints.
The image may still scan, but the encoded credentials can be stale. Create and distribute a new QR with the updated network details.
Not exactly. This page starts with an existing QR and focuses on reading it and diagnosing scan-versus-connection failures. A full join workflow also includes how the QR was prepared and what the network expects after the scan.
Recover the current network details from a trusted source and generate a clean replacement rather than trying to preserve an unreadable code.
If the existing code is stale or unreadable, create a new one from the current network details and test it before reposting.
