A Wi-Fi sharing code helps another device join a network without copying the password character by character. First check which network your Pixel is actually connected to. Sharing your home network when you meant to offer the guest network gives the other device a different kind of access.
Open the network’s Share control
On Pixel, open Settings → Network & internet → Internet. With Wi-Fi on, find the connected network, open its settings and choose Share. Verify your identity on the phone if requested, then show the QR code to the intended recipient. Google also documents Share Wi-Fi in the Internet panel of Quick Settings.
The current Pixel guide notes that some instructions require Android 11 or later. Other Android manufacturers can use different labels, so follow the device’s own network-sharing instructions rather than looking for an identical menu everywhere.
Check the result on the other device
On a second device you are allowed to connect, scan the code with a QR scanner that supports Wi-Fi codes and confirm the displayed network name. After joining, open a normal page and check that it is using the expected Wi-Fi. A successful scan alone does not prove that internet access works.
Only share a network you are authorized to share. Treat the QR code as access information: avoid leaving its screenshot in a public album or chat. If the receiving device stays connected later, manage that saved network on the receiving device. Closing the code on your Pixel is not a remote disconnection command.
