1. Before logging in to HowNet again, click Tools-Internet Options to delete cookies, so you won't be prompted "logged in" the next time you log in, but you can't post now.

2. When downloading the paper, don't click "CAJ full-text download". Right-click this hyperlink, select "Save Target As" and save it to your computer.

3. If you can't save the right-click target in the middle of the world browser window, you can change it to IE.

I think the reason for this situation is that you installed a security program to prevent the browser from popping up windows and advertising pages. You can directly whitelist CNKI's website in this program.

There is no problem that the IP address of education network cannot download CNKI papers, and many servers of CNKI are set up on education network. Your mistake is basically that you can't call the "pop-up webpage download" program.

I hope I can help you solve the problem. If you have questions, please leave a message!

I also went to your school for training in this field in 2007, haha!
