Most laptops have a way to turn off the wireless antenna and it is easy to turn it off accidentally. Find the switch and turn it back on if it is off. First look to the sides of the laptop, typically it will be a slide switch marked with an antenna with semi-circles around it. Some laptops place this button next to the monitor.
Examples of wireless antenna icons:
Other laptops may use a keyboard shortcut using the laptops FN key and a function key. The function key will be marked with a tiny wireless icon.
Be patient when you turn this on it may take time for your PC to recognize that the antenna is on. After a few seconds try to connect to a network the way you normally do. If this is your first time try the instructions in this link.
Your PC or other device remembers the settings for any wireless connection you connect to. Sometimes the network changes slightly or settings you tried were not correct. When this happens you need to completely remove the settings with the process known as "forget this network". The academic computing department has complied the instructions for this for any kind of device. Find the link for your device on the ACS page and click the link that corresponds to your device.
Sometimes the setting causing the problem is not in the remembered wireless connection but in a hardware setting instead, for example if you or someone set a fixed IP address to connect in some other location. If you changed your settings you should know how to change them back to connect to a public access point. If not
