PPPoE Encapsulation

The NBG5715 supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF standard

(RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem (DSL,

cable, wireless, etc.) connection. The

PPP over Ethernet

option is for a dial-up connection using

PPPoE.

For the service provider, PPPoE offers an access and authentication method that works with existing

access control systems (for example Radius).

One of the benefits of PPPoE is the ability to let you access one of multiple network services, a

function known as dynamic service selection. This enables the service provider to easily create and

offer new IP services for individuals.

Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires no

specific configuration of the broadband modem at the customer site.

By implementing PPPoE directly on the NBG5715 (rather than individual computers), the computers

on the LAN do not need PPPoE software installed, since the NBG5715 does that part of the task.

Furthermore, with NAT, all of the LANs’ computers will have access.

Wireless LAN

11.1

Overview

This chapter discusses how to configure the wireless network settings in your NBG5715. The

NBG5715 is able to function both 2.4G and 5G network at the same time. You can have different

wireless settings for 2.4G and 5G. Click

Configuration > Network > Wireless LAN 2.4G

or

Wireless LAN 5G

to configure to do so.

See the appendices for more detailed information about wireless networks.

The following figure provides an example of a wireless network.

Figure 42

Example of a Wireless Network

The wireless network is the part in the blue circle. In this wireless network, devices A and B are

called wireless clients. The wireless clients use the access point (AP) to interact with other devices

(such as the printer) or with the Internet. Your NBG5715 is the AP.
