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.

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.
