Shenzhou Benben just comes with a wireless module, there is no network card, you can buy a wireless network card (LAN or WAN card depends on your own needs), generally there are wireless AP coverage areas (such as tea restaurants, companies, libraries and other places) only need a wireless LAN card OK
