What is the way to surf the Internet on campus wlan?

WLAN, namely wireless local area network, is a local area network based on radio frequency communication technology. Although no cable is used, it can provide all the functions of traditional wired LAN. Wireless data communication can be used not only as a supplement and extension of wired data communication, but also as a backup of wired network environment.

Mainly uses the wireless controller AC (access controller) plus AP (access point), and uses the networking mode of the operator's original fixed network system. In the school dormitory area, deploy AP, that is, wireless access point, so that users can connect to the wireless network in the form of notebook or desktop+wireless network card. There are two ways to access the Internet. One is that the user connects to the wireless signal, and then opens any webpage of the browser, which will jump to an authentication page, and then enter the user name and password to surf the Internet. User name and password can be obtained by issuing cards by operators, sending passwords by mobile phones, and applying for services by mobile phones. This authentication method is called web authentication or portal authentication.

The other is to dial-up the internet through the client provided by the operator after connecting to the network, which belongs to PPPOE authentication.
