Do I need a password to surf the Internet with wifi in the university? How did I hear that it takes a month to get the answer on wifi?

Schools generally have campus wireless networks of operators (telecom, China Unicom and mobile), so logging in is definitely necessary. The general monthly fee is 5~ 10 yuan;

Need to apply for opening, you can call customer service or send a text message;

I suggest you ask your senior sister, what are the internet access methods in your school and how much it costs, and then choose.
