3.2.1

PPPoE Connection

Point-to-Point Protocol over Ethernet (PPPoE) functions as a dial-up connection. PPPoE is an IETF

(Internet Engineering Task Force) standard specifying how a host personal computer interacts with

a broadband modem (for example DSL, cable, wireless, etc.) to achieve access to high-speed data

networks.

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

access control systems (for instance, RADIUS).

One of the benefits of PPPoE is the ability to let end users 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 specific users.

Operationally, PPPoE saves significant effort for both the subscriber and the ISP/carrier, as it

requires no specific configuration of the broadband modem at the subscriber’s site.

By implementing PPPoE directly on the NBG-418N v2 (rather than individual computers), the

computers on the LAN do not need PPPoE software installed, since the NBG-418N v2 does that part

of the task. Furthermore, with NAT, all of the LAN's computers will have Internet access.

DESCRIPTION

IP Address

Select this option if you were given IP address and/or DNS server settings by the

ISP. The fixed IP address should be in the same subnet as your broadband modem

or router.

Subnet Mask

Enter the subnet mask address in this field.

Default Gateway

Enter the gateway IP address provided by your ISP.

Primary DNS

DNS (Domain Name System) is for mapping a domain name to its corresponding

IP address and vice versa. The DNS server is extremely important because

without it, you must know the IP address of a computer before you can access it.

The NBG-418N v2 uses a system DNS server (in the order you specify here) to

resolve domain names for DDNS and the time server. Enter the primary DNS

server’s IP address in this field.

Secondary DNS

Enter the secondary DNS server’s IP address in this field. This field is optional.

wireless radio

Click this check box to disable the WLAN in the NBG-418N v2.

SSID

Enter a descriptive name (up to 32 printable 7-bit ASCII characters) for the wireless LAN.

If you change this field on the NBG-418N v2, make sure all wireless stations use the same

SSID in order to access the network.

Channel

The range of radio frequencies used by IEEE 802.11b/g/n wireless devices is called a

channel.

Set the operating frequency/channel depending on your particular region. Select a channel

from the drop-down list box. The options vary depending on the frequency band and the

country you are in.

Select

Auto

to have the NBG-418N v2 automatically choose the channel with the least

interference.

Mode

Select the IEEE 802.11 WLAN mode you wish to use on the NBG-418N v2 from the drop-

down list.

Channel Width

Select the channel bandwidth you want to use for your wireless network.

Select

Auto 20/40 MHz

to allow the NBG-418N v2 to adjust the channel bandwidth to 40

MHz or 20 MHz depending on network conditions.

Select

20 MHz

if you want to lessen radio interference with other wireless devices in your

neighborhood or the wireless clients do not support channel bonding.

Select

40 MHz

to bond two adjacent radio channels to increase throughput. The wireless

clients must also support 40 MHz.
