1, if the school has a wireless network, you can use the notebook wireless network card to search for wireless network signals to surf the Internet. So you don't need a cat or a route.

2. If there is no wireless network, it is a wired network cable, just plug it directly into the network jack. These are small LANs without any boxes. Instant use!

3. About what charge, it should be in the tuition! When you pay the fee, you should ask whether it is included. Don't regret it afterwards.
