Final answer:
To manually connect to a secured wireless network, access the wi-fi settings, select the desired secured network, and enter the network's password.
Step-by-step explanation:
To manually connect an Android or iOS device to a secured wireless network, the following three steps must be completed:
Access the device's wi-fi settings by going into the settings menu and tapping on Wi-Fi or wireless settings.
Choose the secured wireless network you wish to connect to from the list of available networks.
Enter the network's password when prompted, ensuring that you input it correctly, as the password will be case-sensitive.
Note that if the network is hidden, you may need to enter the network name (SSID) manually before providing the password. Once the password is accepted, your device should indicate that you are connected.
