Forgot the steps to retrieve the campus WLAN password: 1. If the campus WLAN network is created by the school itself, you need to contact the information technology center of the school to retrieve or reset the password. 2. If it is a broadband operator's WLAN network, take CMCC-EDU as an example, send a short message: CZEDUMM to 10086 to reset the password of CMCC-EDU, and then you can log in and visit the CMCC-EDU network normally.
