Check the Wi-Fi settings on a device that is connected to the network at your school to find out what the password is for the wireless Internet. It’s also very likely that your student ID and password will let you get on the network.
If you are using Windows, right-click the Wi-Fi icon in the system tray at the bottom right and click Open Network and Sharing Center. On the left, click Change Adapter Settings.
Then, right-click the Wi-Fi adapter and choose Status from the menu that appears. Click Wireless Properties, go to the Security tab, and check the box next to Network Security Key that says Show Characters. You can now see what the Wi-Fi password is.
If you have a computer that used to be connected to the network but isn’t now, click the Start button, click All Programs, and then click Accessories and then Command Prompt. Type “netsh wlan show profiles” and press Enter. Under Security Settings, look for the password next to Key Content.
On Mac OS X, open Keychain Access by going to Application > Utilities. Double-click on the network you want to use from the list. Type the administrator’s username and password, then click Allow. Check the Show Password box to see the Wi-Fi password.
You might also be able to connect to the network without a separate password. Some schools let students use their IDs and passwords to connect to the Wi-Fi network. When this happens, when you try to connect to a website, the network sends you straight to the login page.
