A Wi-Fi QR code does not connect
The phone recognizes the code but joining fails, or it never offers to join.
Check these in order
- Check the network name. It must match exactly, including capital letters and spaces. Compare it with the name shown on a phone that is already connected.
- Check the security type. Choose the one your router uses. WPA / WPA2 suits most networks. If you pick the wrong one, the phone cannot join.
- Check the password. Retype it in the generator and read it twice. One wrong character is enough to fail.
- Hidden network. Tick Hidden network if your network does not appear in the phone’s Wi-Fi list. Leave it off if it does appear.
- Pick the right network. Many routers have two networks, for example one for 2.4 GHz and one for 5 GHz, with different names. Use the name of the one you want guests to join.
- Try another phone. Some older phones and some tablets do not read Wi-Fi codes, even though they can scan links.
Still not working?
If a phone joins when you type the password by hand but not from the code, the code was made with a different name, security type or password. Make a new one and compare each field. See Make a Wi-Fi QR code.
