How do I solve a network security key mismatch?

1. Check the network name (SSID) of the Wi-Fi network that you’re connected to for any typos or mistakes, or whether the name has changed.
2. Confirm that the Wi-Fi network you intend to connect to is visible within the list of networks available.
3. Validate the security key used for the Wi-Fi connection. Ensure that both the router and the device have the same key.
