Can't I surf the internet with a free broadband connection to the computer in the hotel?

Hotels use local area networks. You can set up automatic IP acquisition, or consult the service desk to obtain the IP address and set it manually.

Connect the network with a friend's notebook, and then manually set the IP address of your computer to the same IP address segment according to his IP address. How to view its IP address: My Desktop Network Neighbors right-click Properties and double-click Local Area Connection to view the support page.
