hp digital home networking ethernet USB network adapter
Congratulations on your purchase of the HP Digital Home Networking Ethernet USB
Adapter. The HP Digital Home Networking Ethernet USB Network Adapter is plug
and play. You can connect instantly to a network from a USB-enabled desktop or
notebook computer with Windows 98, Millennium, 2000, or XP.
Connect a standard network Ethernet cable to one end of the adapter and the USB
cable to the other, install the included network software drivers, and you will be
networked.
Since the adapter is bus powered, it draws power from your PC and requires no
external power cords. The adapter features a maximum of 12 Mbps throughput (the
maximum supported by USB), easy-to-read LEDs, and compact design.

troubleshooting
Windows does not detect new hardware with the Ethernet USB Network Adapter
hardware installed, or it continues to detect the adapter each time I restart the PC.
❑ Verify that the adapter is securely inserted into the appropriate port on your
computer.
❑ Verify that your system BIOS is USB compatible and that your PC’s USB settings
are enabled. The motherboard of your PC may have USB options not supported
by your Windows operating system. If you are not sure, contact your PC’s
manufacturer.
Windows can’t locate the driver for the Ethernet USB Network Adapter.
❑ Be sure you have inserted the correct CD-ROM into your PC’s drive.
❑ The CD-ROM may be defective, files may be missing, or you may be pointing
Windows to the wrong drive. Confirm that the CD-ROM includes the files
USB100TX.inf and USB100TX.sys. If the files are not on the CD-ROM, contact
HP customer care (see your Quick Start Guide for further information).
The Windows logon screen doesn’t appear after restarting the computer.
❑ Click Start, then click Log Off and log back on. If this doesn’t solve the
problem, the PC manufacturer may have disabled Windows networking.
Contact the manufacturer for help. For Windows 2000, consult your Microsoft
documentation.
On the Access Control tab, user level access is selected, but Shared Level Access is
grayed out and not accessible.
❑ The primary network logon is set to Client for NetWare Networks. On the
Configuration tab of the Network Properties window, set the primary network
logon to Client for Microsoft Networks.
❑ Your personal Web server PC or Microsoft Front Page may require you to
choose a user level for security reasons.
In Network Neighborhood I can see my computer but not others.
❑ Verify that the cables are connected correctly. Confirm that the Link or Activity
LEDs are lit on both the Ethernet USB Network Adapter and your hub if you are
using one. Replace the cable with one you know works.
❑ Verify that the other computers are turned on.

glossary
10BaseT
Ethernet standard topology for twisted pair (T) cabling (transfer rate of 10 Mbps
over 100 meters).
100BaseT
Fast Ethernet twisted pair cabling (transfer rate of 100 Mbps over 100 meters).
ad-hoc network
Group of computers, each with a wireless LAN network adapter, connected as
an independent wireless local area network for the duration of a single
communications session. An ad-hoc wireless LAN is applicable at a
departmental scale for a branch or SOHO (small office/home office) operation.
ADSL (Asymmetric Digital Subscriber Line)
A DSL modem technology geared to acceptable Internet performance in which
downstream data transfer (downloading data from the Internet to the subscriber)
is faster than upstream data transfer (uploading data from the subscriber).
ATM (Asynchronous Transfer Mode)
Asynchronous transfer mode (broadband switching). ATM (asynchronous
transfer mode) — a dedicated-connection switching technology that transmits
digital data over a physical medium using digital signal technology. An
individual cell is processed asynchronously relative to other related cells and is
queued before being multiplexed over the transmission path.
broadband
Fast Internet access through DSL, cable modem, or other means.
BSS (Basic Service Set)
One wireless network.
BSSID (Basic Service Set Identification)
A unique name (or ID) used by all computers on the network. A specific ad-hoc
LAN. Computers in a BSS must be configured with the same BSSID.
bus topology
Simple way of connecting computers in a network linearly along a single cable
(each connected to the cable, not one to another).
19
Ethernet USB network adapter
client/server network
Network in which one computer (the “server”) shares resources with other
computers, called “clients” (as opposed to a peer-to-peer network).
CSMA/CD (Carrier Sense Multiple Access/Collision Detect)
The protocol for carrier transmission access in an Ethernet network in which
each device senses whether the line is idle and then sends data. If another
device sends data at the same time, a collision occurs, the data is discarded,
and the devices try again.
default gateway
The router used to forward all traffic not addressed to a station within the local
subnet.
DHCP (Dynamic Host Configuration Protocol)
A utility for assigning TCP/IP addresses to workstations automatically (a unique
IP address must be assigned to each computer in the network). When computers
are moved within the network, DHCP allows automated IP addresses to be
assigned automatically. DHCP “leases” an IP address to a device for a specific
amount of time, which is useful in education and other environments where
users change frequently. DHCP also supports static IP addresses for computers
needing a permanent IP address, such as those containing Web servers. See
static IP address.
DCHP Client
A device configured to receive a DHCP address.
DHCP Server
A device configured to assign IP addresses to DHCP clients.
DMZ (Demilitarized Zone)
Computer host or small network inserted as a “neutral zone” between a
company’s private network and the external public network. It prevents outside
users from having access to an internal server containing confidential data.
DMZ Hosting
Allows one IP address (or computer) to be exposed to the Internet. Some
applications require multiple TCP/IP ports to be open. It is recommended that
you set your computer with a static IP address if you want to use DMZ Hosting.
20
DNS (Domain Name System)
Method for matching Internet domain names with IP addresses. When a
Uniform Resource Locator (URL) is entered into a Web browser, a domain name
server retrieves the corresponding IP address for the domain name specified
(“name resolution”) and sends the request to the appropriate server. Domain
names are convenient “handles” for IP addresses.
DSL (Digital Subscriber Line)
Transmits data bi-directionally at high speeds.
DSSS (Direct Sequence Spread Spectrum )
Generates a redundant bit pattern for each bit to be transmitted. This bit pattern
is called a chip (or chipping code). The longer the chip, the greater the
probability that the original data can be recovered. Even if one or more bits in
the chip are damaged during transmission, statistical techniques embedded in
the radio can recover the original data without the need for retransmission. To
an unintended receiver, DSSS appears as low-power wideband noise and is
rejected (ignored) by most narrowband receivers.
dynamic IP address
glossary
An IP address that is automatically assigned (typically by a DHCP server) in a
TCP/IP network, as opposed to a static IP address.
ESS (Extended Service Set)
More than one wireless network.
ESSID (Extended Service Set Identification)
A unique name (or ID) used by users roaming among the multiple wireless
networks. An infrastructure configuration can support roaming capability for
mobile workers. More than one BSS can be configured as an ESS. Users within
an ESS can roam freely between BSSs while served as a continuous connection
to the network. Wireless stations and wireless access points within an ESS must
be configured with the same ESSID and radio channel.

Ethernet card
See NIC (Network Interface Card).
21
Ethernet USB network adapter
FHSS (Frequency Hopping Spread Spectrum)

single logical channel. To an unintended receiver, FHSS appears to be shortduration impulse noise.
firewall
A set of related programs, located at a network gateway server, that protects
the resources of a network from users in other networks. It also controls access
of internal users to outside resources. A firewall, working closely with the
