Checking the Wi-Fi settings on a device that is linked to the network will reveal the wireless Internet password of your school. Additionally, it is quite likely that your student ID and password will grant you access to the network.
To open the Network and Sharing Center on a Windows computer, right-click the Wi-Fi icon in the system tray on the right and select Open Network and Sharing Center. Click Change Adapter Settings on the left, then pick Status from the context menu after right-clicking the Wi-Fi adapter. Check the Show Characters box under Network Security Key on the Security tab of the Wireless Properties window. You can now view the Wi-Fi network’s password.
If you have a machine that was formerly linked to the network but is no longer, click the Start button, select All Programs, and then click Accessories Command Prompt. Enter “netsh wlan display profiles” and press Enter. Under Security Settings, locate the password next to Key Content.
Launch Keychain Access from the Utilities folder under Application on Mac OS X. Double-click the network you wish to connect to from the list. Enter the username and password for the administrative account, and then click Allow. Check the Show Password box to see the Wi-Fi password.
It is also possible to connect to the network without a distinct password. Using their student IDs and passwords, some schools permit students to connect to the Wi-Fi network. In such instances, when you attempt to connect to a website, the network automatically redirects you to the login page.
