Broadband
5.1 Overview
This chapter discusses the ZyXEL Device’s Broadband screens. Use these screens to configure
your ZyXEL Device for Internet access.
A WAN (Wide Area Network) connection is an outside connection to another network or the
Internet. It connects your private networks, such as a LAN (Local Area Network) and other
networks, so that a computer in one location can communicate with computers in other locations.

5.1.2 What You Need to Know
The following terms and concepts may help as you read this chapter.
Encapsulation Method
Encapsulation is used to include data from an upper layer protocol into a lower layer protocol. To set
up a WAN connection to the Internet, you need to use the same encapsulation method used by your
ISP (Internet Service Provider). If your ISP offers a dial-up Internet connection using PPPoE (PPP
over Ethernet), they should also provide a username and password (and service name) for user
authentication.
