Objective:Raspberry Pi has a variety of networked ways, either via a wired network or via a wireless network. Through the wired network connection is relatively simple, in the DHCP-enabled router, directly plug in the network cable can be networked, this article introduces the way of the Raspberry Pi wireless networking. Without the network, if there is no screen
