Why can't the educational administration online of Jiangxi Normal University and the website of the library always get in? I run 2M broadband of Normal University Telecom.
One way to get in is to use the intranet of Normal University. For example, the account we usually use is "Student ID @jxsd" and the password is the last six digits of the student ID. If we change the account number to "student number @jxnu" and the password is still the last six digits of the student number, we can access the educational administration website and the library website. I just can't use jxnu's account to browse other web pages, so I can only go to the educational administration online and library of Jiangxi Normal University. If I want to browse other web pages, I can switch back to jxsd.
