Ruijie networking problem

This question should first be consulted by the staff of the school management network to see if there are any special settings and requirements in the school. Do it.

Secondly, if you don't have any special requirements, but think it's your own equipment problem, you can use third-party software to repair the network:

Suggestion:

① Please use third-party software to repair, such as: 360 security guards → system repair → hot issues → abnormal Internet access.

②360 Security Guard → Functional Encyclopedia → Network Optimization → Repair Network (LSP)→ Repair immediately.

As for the last tip, it is to warn the school to install the software ☆ over the wall ☆ privately, which can also be turned off.
