PPPoE (Point-to-Point Protocol over
Ethernet): A speciﬁ cation for connecting
users on an Ethernet line to the Internet
through a common broadband medium.
Protocol: A standard way of exchanging
information between computers.
RADIUS (Remote Authentication Dial
In User Service): A server that issues
authentication keys to clients.
RAM (Random Access Memory): Non-
Repeater Hub: A device that collects,
strengthens and transmits information to
all connected devices, allowing the network
to be extended to accommodate additional
workstations. See also Bridge.
RC4: The encryption algorithm used by
RJ-45 connector: An 8-pin connector
used between a twisted pair cable and a
data transmission device. ROM (Read Only Memory): Memory
hardware that allows fast access to
permanently stored data but prevents
addition to or modiﬁ cation of the data.
Router: A device in a network that
handles message transfer between
computers. Similar to a hub, but with
added functionality and efﬁ ciency.
Roaming: The ability to use a wireless
device while moving from one access point
to another without losing the connection.
Server: Any computer that makes ﬁ les or
peripheral devices available to users of the
network and has a resident Network OS.
SMTP (Simple Mail Transfer Protocol):
The protocol used to deﬁ ne and deliver
electronic mail (E-mail) from one location
Page 77 from 84
SNMP (Simple Network Management
Protocol: An application layer protocol
that outlines the formal structure for
communication among network devices.
Static IP Address: A permanent IP
address is assigned to a node in a TCP/IP
network. Also known as global IP.
STP (Shielded Twisted Pair): Twisted Pair
cable wrapped in a metal sheath to provide
extra protection from external interfering
Subnet Mask: An eight-byte address
divided into 4 parts separated by periods.
TCP/IP (Transmission Control Protocol/
Internet Protocol: Protocol used by
computers when communicating across
the Internet or Intranet.
TKIP (Temporal Key Integrity Protocol):
An encryption method replacing WEP.
TKIP uses random IV and frequent key
exchanges. Topology: The shape of a LAN (Local Area
Network) or other communications system.
Twisted Pair: Cable that comprises 2
or more pair of insulated wires twisted
UDP (User Datagram Protocol): A
communication method (protocol)
that offers a limited amount of service
when messages are exchanged between
computers in a network. UDP is used as
an alternative to TCP/IP.
Uplink: Link to the next level up in a
UTP (Unshielded Twisted Pair) cable:
Two or more unshielded wires twisted
together to form a cable.
WAN (Wide Area Network): A networking
system covering a wide geographical area.
Page 78 from 84
WEP (Wired Equivalent Privacy): A
security protocol for wireless local area
networks deﬁ ned in the 802.11b standard,
using a 64 bit or 128 bit key. WEP was
designed to provide the same level of
security as that of a wired LAN. However, it
has been found that WEP is not as secure
as once believed.
Web Browser: A software program that
allows viewing of web pages.
Wi-Fi (Wireless Fidelity): An organization
that tests and assures interoperability
among WLAN devices.
Wire Speed: The maximum speed at
which a given packet can be transferred
using Ethernet and Fast Ethernet standard
WLAN (Wireless LAN): A LAN topology
using wireless devices. VPN (Virtual Private Network): A security
method to connect remote LAN users to a
corporate LAN system.

This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation.This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and receiver.
•Connect the equipment into an outlet on a circuit different from that to which the receiver
•Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1) this device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired operation.
In accordance with FCC regulation, BUFFALO has limited the WHR-HP-G54 to operation
on channels 1-11 by USA specific firmware.
Changes or modifications not expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment.

equipment and meets the FCC radio frequency (RF) Exposure Guidelines in Supplement C
to OET65. This equipment should be installed and operated with at least 20cm and more
between the radiator and person’s body (excluding extremities: hands, wrists, feet and
legs). This transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.
This equipment is designed with the utmost care for the safety of those who install and
use it. However, special attention must be paid to the dangers of electric shock and static
electricity when working with electrical equipment. All guidelines of this manual and of the
computer manufacturer must therefore be allowed at all times to ensure the safe use of
