About Wi-Fi profiles
A Wi-Fi® profile contains the information that you require to connect to a Wi-Fi network. You can have more than one Wi-Fi profile on your BlackBerry® device. For example, you can have one Wi-Fi profile that you use to connect to a Wi-Fi network at home and another Wi-Fi profile that you use to connect to your organization's Wi-Fi network. You can also have Wi-Fi profiles that you use to connect to Wi-Fi networks in public places such as community centers or libraries.
Your device tries to connect to Wi-Fi networks based on the order in which they appear in your Wi-Fi profile list.
