I don't think I can play. Although it is a wireless network, it is not the same as the actual wireless network. The wireless network of the library can only be called WLAN. In fact, the link will be the same as the campus network. If he restricts the campus network, he can't play mainstream games and doesn't open a dedicated port, your game can't be connected. If the campus network traffic is limited, it is generally stuck. But you can still try. Practice is the only criterion for testing all truth.
