Click the wireless network in the lower right corner, click the wireless network in the library, and then do it quickly. I can find it in Yuwen Building. It's not very fast, but it's ok to open the webpage. It is definitely not possible to download things on QQ, only 20-30 KB/s, so try more if you can't get on it. If not, try again later. The network is too broken. That's all I can say.
