Do the WAN and LAN ports work the same when the device is in
different modes?
No, the WAN and LAN ports have slightly different functions depending on the
operating mode of the device.
a.
In
Wi
Fi router
mode, the
WAN port
is for a direct connection to your xDSL
modem. The
LAN ports
are for wired network clients.
b.
In
access point
mode, the
WAN port
is not functional. Connect your existing
router to the device’s
LAN port
, and the other
LAN ports
can connect wired
network clients.
c.
In
range extender
mode, the
WAN port
is not functional and the
LAN ports
are
for wired network clients. Do not connect your existing router to the device’s
WAN
or
LAN ports
, as this can cause the device to malfunction.

My network is configured to use static IP addresses. How can I
assign a static IP address to my BR
6228nS V2/nC V2?
a.
You can modify the device’s IP address using the browser based configuration
interface. Please refer to

Glossary
Default Gateway (Wireless bridge):
Every non
access point IP device needs to
configure a default gateway’s IP address. When the device sends out an IP
packet, if the destination is not on the same network, the device has to send
the packet to its default gateway, which will then send it out towards the
destination.
DHCP:
Dynamic Host Configuration Protocol. This protocol automatically gives
every computer on your home network an IP address.
DNS Server IP Address:
DNS stands for Domain Name System, which allows
Internet servers to have a domain name (such as www.Broadbandaccess
point.com) and one or more IP addresses (such as 192.34.45.8). A DNS server
keeps a database of Internet servers and their respective domain names and
IP addresses, so that when a domain name is requested (as in typing
"Broadbandaccess point.com" into your Internet browser), the user is sent to
the proper IP address. The DNS server IP address used by the computers on
your home network is the location of the DNS server your ISP has assigned to
you.
DSL Modem:
DSL stands for Digital Subscriber Line. A DSL modem uses your
existing phone lines to transmit data at high speeds.
Ethernet:
A standard for computer networks. Ethernet networks are
connected by special cables and hubs, and move data around at up to 10/100
million bits per second (Mbps).
IP Address and Network (Subnet) Mask:
IP stands for Internet Protocol. An IP
address consists of a series of four numbers separated by periods, that
identifies a single, unique Internet computer host in an IP network. Example:
192.168.2.1. It consists of 2 portions: the IP network address, and the host
identifier.
The IP address is a 32
bit binary pattern, which can be represented as four
cascaded decimal numbers separated by “.”: aaa.aaa.aaa.aaa, where each
“aaa” can be anything from 000 to 255, or as four cascaded binary numbers
separated by “.”: bbbbbbbb.bbbbbbbb.bbbbbbbb.bbbbbbbb, where each “b”
can either be 0 or 1.

A network mask is also a 32
bit binary pattern, and consists of consecutive
leading 1’s followed by consecutive trailing 0’s, such as
11111111.11111111.11111111.00000000. Therefore sometimes a network
mask can also be described simply as “x” number of leading 1’s.
When both are represented side by side in their binary forms, all bits in the IP
address that correspond to 1’s in the network mask become part of the IP
network address, and the remaining bits correspond to the host ID.
For example, if the IP address for a device is, in its binary form,
11011001.10110000.1001
0000.00000111, and if its network mask is,
11111111.11111111.11110000.00000000
It means the device’s network address is
11011001.10110000.1001
0000.00000000, and its host ID is,
00000000.00000000.00000000.00000111
. This is a convenient and efficient
method for access points to route IP packets to their destination.
ISP Gateway Address:
(see ISP for definition). The ISP Gateway Address is an
IP address for the Internet access point located at the ISP's office.
ISP:
Internet Service Provider. An ISP is a business that provides connectivity
to the Internet for individuals and other businesses or organizations.
LAN:
Local Area Network. A LAN is a group of computers and devices
connected together in a relatively small area (such as a house or an office).
Your home network is considered a LAN.
MAC Address:
MAC stands for Media Access Control. A MAC address is the
hardware address of a device connected to a network. The MAC address is a
unique identifier for a device with an Ethernet interface. It is comprised of
two parts: 3 bytes of data that corresponds to the Manufacturer ID (unique
for each manufacturer), plus 3 bytes that are often used as the product’s
serial number.
NAT:
Network Address Translation. This process allows all of the computers
on your home network to use one IP address. Using the broadband access
point’s NAT capability, you can access the Internet from any computer on
your home network without having to purchase more IP addresses from your
ISP.
Port:
Network Clients (LAN PC) uses port numbers to distinguish one network
application/protocol over another. Below is a list of common applications and
protocol/port numbers:

Access point:
A access point is an intelligent network device that forwards
packets between different networks based on network layer address
information such as IP addresses.
Subnet Mask:
A subnet mask, which may be a part of the TCP/IP information
provided by your ISP, is a set of four numbers (e.g. 255.255.255.0) configured
like an IP address. It is used to create IP address numbers used only within a
particular network (as opposed to valid IP address numbers recognized by the
Internet, which must be assigned by InterNIC).
TCP/IP, UDP:
Transmission Control Protocol/Internet Protocol (TCP/IP) and
Unreliable Datagram Protocol (UDP). TCP/IP is the standard protocol for data
transmission over the Internet. Both TCP and UDP are transport layer protocol.
TCP performs proper error detection and error recovery, and thus is reliable.
UDP on the other hand is not reliable. They both run on top of the IP (Internet
Protocol), a network layer protocol.
WAN:
Wide Area Network. A network that connects computers located in
geographically separate areas (e.g. different buildings, cities, countries). The
Internet is a wide area network.
Web
based management Graphical User Interface (GUI):
Many devices
support a graphical user interface that is based on the web browser. This
means the user can use the familiar Netscape or Microsoft Internet Explorer
to Control/configure or monitor the device being managed.
