Our school library is equipped with a wireless router, so I can surf the Internet wirelessly in my notebook if I need anything else.
Generally speaking, your laptop is equipped with a wireless network card. If not, you need to install it. If you have it, open it. Right-click my computer, properties, hardware, device manager, network card, which has a wireless network card. Just see the word wireless. After the computer is turned on, there should be a wireless switch button on the computer keyboard. After pressing, click the wireless network logo in the lower right corner, and then search for available networks.
