introduction

hp digital home networking wireless gateway
Congratulations on your purchase of the HP Digital Home Networking Wireless
Gateway. The Wireless Gateway is the perfect solution for connecting your wireless
network to a high-speed broadband cable modem or Digital Subscriber Line (DSL)
Internet connection.
Your Gateway can be configured as a Dynamic Host Configuration Protocol
(DHCP) server, which means that it can automatically assign Internet Protocol (IP)
addresses to PCs in your Local Area Network (LAN). The Gateway becomes your
only visible network device on the Internet.
The Gateway also serves as your Internet firewall, protecting your networked PC’s
from access by external users. All incoming data is monitored and filtered using a
firewall. You can configure your Gateway to permit playing Internet games and
video conferencing. You also can use IP filtering to block your users from access to
the Internet as needed. Now all of your network users can enjoy fast broadband
Internet access and can share internal data.
A typical gateway (router) relies on a hub or switch to share its Internet connection,
but the HP Wireless Gateway, in addition to its wireless capabilities, also channels
the Internet connection through the full duplex speed of its built-in Ethernet 4-port
switch. This combination of wireless gateway and switch technology eliminates the
need to buy an additional hub or switch and extends the range of your wireless
network. Now your entire wireless network can enjoy fast broadband Internet
connections supported by its robust switched backbone. With the dual-function
speed and power of the Wireless Gateway, your network will operate faster than
you ever imagined.

Adapter to the Power port.

Antenna Jacks

Connect the included antennas to the
antenna jacks.

reset button
To refresh Gateway connections and attempt to fix routing problems, very briefly
depress the Reset button with a paper clip.
If you have exhausted all troubleshooting options (see the Troubleshooting section of
this user’s guide) and continue to experience serious routing problems, depress the
Reset button for about five seconds to clear all of the Gateway data and restore
the factory default settings.
Warning: Resetting the Gateway may create conflicts between your PC’s actual IP
addresses and what the Gateway expects them to be. You may be forced to restart the
entire system.
If the Gateway locks up, unplug the Power Adapter from the Gateway’s Power Port
for 3 to 5 seconds (but not longer) and then plug it back in. Leaving the power off
for too long could result in the loss of network connections.

setting up a wireless network
network topology
A wireless Local Area Network (LAN) uses a wireless adapter to connect each
computer to the network. Computers in a wireless network must be configured to
share the same radio channel.
The Wireless USB Network Adapter provides wireless computers access to a wired
network. This integrated wireless and wired network is called an “infrastructure”
configuration. A group of wireless-network-adapter-equipped computers plus a
wireless access point, such as the HP Wireless Network Access Point, is called a
Basic Service Set (BSS). The wireless access point connects the wireless network to
the conventional wired network. Each wireless-adapter-equipped computer can
communicate with any computer in a wired network infrastructure via the wireless
access point.
An infrastructure configuration doubles the effective wireless transmission range of
two wireless-adapter-equipped PCs since the wireless access point forwards data
within the network. It is essential to use a unique ID (a BSSID, or simply, an SSID)
within a wireless network. All PCs within an independent wireless network that are
configured without roaming options (see Roaming below) must be configured with
the same wireless network ID.
The wireless network infrastructure configuration is appropriate for enterprise-scale
wireless access to a central database and for mobile users.

roaming
Infrastructure mode also supports roaming capabilities for mobile users. Multiple
wireless network can be configured as an “extended” wireless network, known as
an Extended Service Set (ESS), allowing users to roam freely within it. All wirelessadapter-equipped PCs within one extended network must be configured with the
same extended network ID (an ESSID, or taken generically with a BSSID as
discussed above, often called an SSID,) and must use the same radio channel.
Before enabling an extended wireless network with roaming capability, select a
feasible radio channel and an optimal location for the wireless access point. Proper
wireless access point positioning and a clear radio signal will enhance
performance.

gateway system tray application

overview
The Gateway installation wizard installed an application on your computer that
functions as a tool kit for your Gateway. The application is accessed from a green,
red, or yellow house icon in the Windows System Tray. The Window System Tray is
in the recessed area of the Windows taskbar in the lower right of your screen.
If you did not authorize installation of the icon during Gateway installation, or if
you deleted the icon by choosing Exit from the pop-up menu, you can reinstall the
icon from the Windows Start menu. Click Start > Programs > HP Digital
Home Networking > Gateway System Tray Application. You can access
the System Tray application from any computer on your network.
The color of the house icon (green, red, or yellow) reflects the status of the network’s
Internet connection and your computer’s ability to communicate with the Gateway:
❑

Green: all is well This computer is connected to the home network with an
active Internet connection.

Gateway System Tray icon (green)

❑

Red: no Internet connection This computer is connected to the home
network, but there is no active Internet connection.

Gateway System Tray icon (red)

❑

Yellow: connection to Gateway lost This computer is no longer
connected to the home network or to the Internet.

Gateway System Tray icon (yellow)

Besides providing constant feedback through the icon color, the Gateway System
Tray application provides additional functionality:
❑

If there is any change in network status, a status notification window appears
on your screen describing the changed situation.

❑

Right-click the Gateway System Tray icon to bring up a menu allowing you to
access the Gateway Control Panel, generate special status or diagnostic
reports, download and install software or firmware upgrades, and launch
additional Gateway utilities.

status notification windows

status notification windows
Any change in network status generates a status notification window describing the
change and, if needed, suggests actions to take. The change may also cause a
color change in the System Tray icon. (These same windows appear when you
select Get current network status from the System Tray pop-up menu. If all the results
are "ok", the utility has not detected any connection problems. If you do receive an
error message, however, see the table “Internet Connection Diagnostic” on
page 25 for more information.)
Note: This automatic notification feature is controlled by a toggle option in the
System Tray pop-up menu described in “Notify me when network events occur” on
page 27.
The following are examples of status notification windows, along with explanatory
comments (notice that the color of the house icon on the screen matches the color of
the icon on the System Tray):

frequently asked questions (FAQs)

gateway general information
What is Network Address Translation and what is it used for?
Network Address Translation (NAT) translates multiple IP addresses on the
private LAN to one public address that is sent out to the Internet. This adds a
level of network security since the addresses of PCs connected to the private
LAN are never transmitted over the Internet. NAT also allows the Gateway to be
used with low-cost Internet accounts, such as DSL or cable modem, where only
one Transmission Control Protocol/Internet Protocol (TCP/IP) address is
provided by the Internet Service Provider (ISP). The user may have 253 private
addresses behind this single address provided by the ISP.
What type of firewall does the Gateway have?
The Gateway uses NAT and TCP/IP port inspections.
Is the Gateway cross-platform compatible?
Any platform that supports Ethernet and TCP/IP is compatible with the
Gateway.
Does the Gateway replace a modem? Is there a cable or DSL modem in the
Gateway?
No, the Gateway must work in conjunction with a cable or DSL modem.
Which modems are compatible with the Gateway?
This Gateway is compatible with virtually any cable or DSL modem that
supports Ethernet.
How can I check whether I have static or DHCP IP Addresses?
Consult your ISP to obtain this information.
How do I get mIRC to work with the Gateway?
On the PC on which you are using mIRC, click the Forwarding tab on the
Expert Interface and set Port forwarding to 113 (see “forwarding” on
page 70 of the Appendix: Expert Interface). If you experience difficulty after
setting port forwarding, try changing the Direct Client-to-Client (DCC) settings to
a range from 1024 to 1030 on the DCC option of the Forwarding settings

wireless gateway

page of the Expert Interface.
How can I block corrupted FTP downloads?
If you are experiencing corrupted files when you download a file with your FTP
client, try using another FTP program.
What is DMZ Hosting?
Demilitarized zone (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.
If DMZ Hosting is used, does the exposed user/PC share the public IP address with
the Gateway?
No.
Does the Gateway pass PPTP packets or actively route PPTP sessions?
The Gateway allows Point-to-Point Tunneling Protocal (PPTP) packets to pass
through.

access control.

wireless gateway

installation and configuration options
How many IP addresses can the Gateway support?
The Gateway supports a maximum of 253 IP addresses.
Where is the Gateway installed on the network?
In a typical environment, the Gateway is installed between the modem and the
LAN. Plug the Gateway into the cable or DSL modem's Ethernet port.
Does the Gateway support any operating system other than Windows 95, 98, Me,
2000, NT, or XP?
Yes, but Hewlett-Packard does not provide technical support for setup,
configuration, or troubleshooting of any non-Windows operating systems at this
time.
If all else fails in the installation, what can I do?
Reset the Gateway by depressing the Reset button for at least three seconds,
then reset your cable or DSL modem by powering the unit off and then back on.
Obtain and flash (upload) the latest firmware release from the Hewlett-Packard
Web site (www.hp.com).
Does the Gateway function in a Macintosh environment?
Yes, but the Gateway's setup pages are accessible only through Internet
Explorer v4.0 or Netscape Navigator v4.0 or higher for Macintosh PCs.
I cannot get the Web configuration screen for the Gateway. What can I do?
You may have forgotten to remove the proxy server settings on your Internet
browser, such as Netscape Navigator or Internet Explorer. Or, remove the dialup settings on your browser. Check your browser documentation.
Will the Gateway allow me to use my own public IP addresses and domain, or do I
have to use the IP addresses provided by the Gateway?
The Gateway mode allows customization of your public IP addresses and
domain.
How many ports can be simultaneously forwarded?
Theoretically, the Gateway can establish 520 sessions at the same time, but you
can only forward 10 ranges of ports.

installation and configuration options

What is the maximum number of virtual private network (VPN) sessions allowed by
the Gateway?
One VPN session at a time; the memory buffer on the Gateway is 512 KB.
My Web pages hang up, I get corrupted downloads, or junk characters are being
displayed on the screen. What do I do?
Force your Ethernet network interface card (NIC) to 10 Mbps or half duplex
mode and turn off the Autonegotiate feature temporarily (go to the Network
Control Panel in your Ethernet Adapter's Advanced Properties tab). Check with
your NIC manufacturer for more information.

wireless gateway

supported software
Does the Gateway support ICQ send files?
Yes, with the following fix: from ICQ menu > preference > connections tab >,
select I am behind a firewall or proxy and set the firewall time-out to 80
seconds in the firewall setting. The Internet user can then send a file to a user
behind the Gateway.
How do I get Napster to work with the Gateway?
Napster is fully compatible with the Gateway. During installation select no
idea when asked about your firewall settings. Set your proxy settings to No
Proxy Server in File>Preferences.
I set up an Unreal Tournament server, but others on the network cannot join. What
do I do?
If you are running a dedicated Unreal Tournament (UT) server, you must create
a static IP address for each of the network PCs and forward ports 7777, 7778,
7779, 7780, 7781, and 27900 to the IP address of the server. If you want to
use the UT server admin, forward another port (8080 usually works well), then
in the [UWeb.WebServer] section of the server.ini file, set the ListenPort to 8080
to match the mapped port above and ServerName to the IP assigned to the
Gateway from your ISP.
Can multiple gamers on the LAN log on to one game server and play simultaneously with just one public IP address?
It depends on which network game you’re playing and what kind of game
server you’re using. For example, UT supports multi-login with just one public IP
address.
How do I get Half-Life:Team Fortress to work with the Gateway?
The default client port for Half-Life is 27005. The PCs on your LAN must have
“+clientport 2700x” in the HL shortcut command line; the x would be 6, 7, 8,
and on up. This allows multiple PCs to connect to the same server. One
exception: version 1.0.1.6 won't let multiple PCs with the same CD key connect
at the same time, even if they’re on the same LAN (it’s not a problem with
version 1.0.1.3). For hosting games, the HL server does not need to be in the
DMZ. Just forward port 27015 to the local IP of the server PC. There remains,
however, a problem with people being booted after a few minutes with an
illegible server message.

supported software

Does the Gateway support IPsec?
A new IPsec pass-through feature is now included.

wireless gateway

supported features
What are the advanced features of the Gateway?
The Gateway's advanced features include IP filtering, IP forwarding, dynamic
routing, static routing, DMZ hosting, and MAC address cloning.
Is IPSec Pass-Through supported by the EtherFast Gateway?
Yes, it is a built-in feature that the Gateway automatically enables.
Does the Gateway support IPX or AppleTalk?
No. TCP/IP is the only protocol standard for the Internet and has become the
global standard for communications. Internet Packet eXchange (IPX), a
NetWare communications protocol used only to route messages from one node
to another, and AppleTalk, a communications protocol used on Apple and
Macintosh networks, can be used from LAN to LAN connections, but those
protocols cannot connect from WAN to LAN.
Does the WAN connection of the Gateway support 100 Mbps Ethernet?
Since broadband Internet connections like cable and DSL do not exceed 10
Mbps, the Gateway’s current hardware design only supports 10 Mbps Ethernet
on its WAN port. It does support 100 Mbps through the built-in auto-sensing
Fast Ethernet 10/100 switch on the LAN side of the Gateway.
Does the Gateway support SPI?
Stateful packet inspection (SPI) is a new feature of the Gateway.

upgrade information

upgrade information
How will I be notified of new Gateway firmware upgrades?
All Hewlett-Packard firmware upgrades are posted on the HP website at
www.hp.com, where they can downloaded for free. The Gateway's firmware
can be upgraded with Trivial File Transfer Protocol (TFTP) programs. If your
Gateway’s Internet connection is working well, there is no need to download a
newer firmware version unless that version contains new features that you would
like to use. Downloading a more current version of Gateway firmware will not
enhance the quality or speed of your Internet connection, and may disrupt your
current connection stability.

wireless gateway

troubleshooting

I can’t connect to the Gateway.
❑

Verify that the Gateway is properly installed, the LAN connections are OK (the
LAN LEDs should be lit), and it is powered on.

❑

Verify that the PC is using an IP address between 192.168.1.2 and
192.168.1.254 and thus compatible with the Gateway default IP address of
192.168.1.1.

❑

The subnet mask must be set to 255.255.255.0 to match the Gateway’s subnet
mask. Confirm these settings for the Gateway from the Windows Start button
by selecting Settings > Control Panel > Network (or Network & Dialup Connections) > Local Area Connection > Internet Protocol
(TCP/IP)/Properties.

I can’t browse through the Gateway.
❑

Verify that both ends of the Ethernet cable and power adapter are properly
connected and that the LEDs on the front panel are functioning properly.

❑

If using Windows 98 or Me, verify the TCP/IP setup on the client side. Click the
Windows Start button, select Run, type winipcfg, and click Enter. The PC
should have an IP address of 192.168.1.xxx ("xxx" is from 2 to 254), the
subnet mask should be 255.255.255.0, the default gateway IP should be the
Gateway’s IP address, and it should have DNS. If using Windows 2000, use
ipconfig to obtain this information.

❑

Also, check the same values as indicated in the previous bullet in the Setup tab
of the Gateway’s Expert Interface (see the Setup sections of the Appendix:
Expert Interface of this user’s guide.)

When I enter a URL or IP address, I get a Request timed out error.
❑

Check to see if other PCs give you the same error message. If they do, verify
that your workstations’ IP settings are correct (IP address, subnet mask, default
gateway, and DNS server).

❑

If the PCs are configured correctly but still not working, check the Gateway.
Verify that it is connected and powered on. Connect to the Gateway and check
its settings. If you cannot connect to it, check the LAN and power connections.

❑

If the Gateway is configured correctly, check your Internet connection
(broadband modem) to see that it is working correctly.

❑

Manually configure the TCP/IP with a DNS address provided by your ISP.

wireless gateway

I can’t obtain an IP address from my cable or DSL modem.
❑

Verify that all of your cabling is properly connected and that the Gateway’s
WAN and LAN LEDs are lighting up.

❑

Power down your cable or DSL modem for a few seconds, then turn it back on.
After the modem goes through its self-test, see if you now have an IP address.

❑

Verify that your cable or DSL modem is DHCP-capable.

❑

You may have to enter the host or domain name on the Setup page of the
Gateway’s Expert Interface. See “setup” on page 53 of the Appendix: Expert
Interface.

❑

Your ISP may require MAC Addresses. Check with your ISP. This MAC address
can be obtained on the Status screen of the Gateway’s Expert Interface.

I can’t get a link to a modem, hub, or switch for one of my ports.
❑

Verify that your cabling is undamaged and is connected properly.

❑

Verify that your network interface adapter has been properly installed.

❑

Verify that both the Gateway and the other device are powered on.

❑

If you are linking to a hub or a switch, be sure that the other device is
functioning properly.

❑

If you are connecting to a cable modem, try plugging it into the Gateway’s
uplink port rather than into a LAN port.

❑

If all else fails, reset the Gateway by depressing the Reset button with a paper
clip. If you continue to experience serious routing problems, depressing the
Reset button for about five seconds will clear all of the Gateway data and
restore the factory default settings. However, be cautious before resetting the
Gateway since doing so risks creating conflicts between your PCs’ actual IP
addresses and what the Gateway expects them to be, and you may be forced
to restart the entire system.

I can’t access my e-mail or the Internet.
❑

Some ISPs, especially cable providers, configure their networks so that you
don’t have to enter a full Internet address into your Web browser or e-mail
application to reach your home page or receive your e-mail.

❑

You must obtain this information before connecting the Gateway to your
network: ask your ISP.

wireless gateway

setting WEP encryption
Note:

WEP Encryption is an additional data security measure that is not
essential for Gateway operation.

Wired Equivalent Privacy (WEP) encryption is a method of encrypting data
transmitted over a wireless network to insure data security. In a wired network, data
security is maintained through the physical wire. WEP encryption provides the same
level of security for wireless data as if transmitted over standard network cabling.
In order to duplicate wired network security levels, wireless data is encrypted at the
point of transmission and decoded by the receiving device, allowing users to have
the same amount of security over their wireless network as they would over a wired
network. This level of security is in addition to that already provided by the
password protection of your network operating system.
The present standard for this encryption as set by the Institute of Electrical and
Electronics Engineers is defined as 40-bit (sometimes also called 64-bit) encryption.
These numbers refer to the complexity of the algorithms generated in order to code
and decode the data transmitted. The higher the bit number, the greater the
complexity of the algorithm and the more secure the encryption.
Higher levels of encryption often negatively affect network data transmission rates.
This encryption is not necessary for the operation of your wireless network device. If
ordinary password protection is sufficient, disregard WEP encryption. However, if
password prtection is not sufficient, then enable WEP encryption.
To enable WEP encryption:
1 Click the Setup tab of the Expert Interface
2 Select Enable under the Wireless field.
3 Select Mandatory under the Wireless WEP field.

may need to create a manual key to meet the requirements of existing wireless
equipment on your network. Check your documentation or with your system
administrator. Choose one of the following options:
❑

To generate an encryption key with a passphrase (recommended):
1 Enter a text string in the Passphrase box; the string may be up to 31
alphanumeric characters.
2 Click Generate.
3 Click Apply.

forwarding
Select the Forwarding tab of the Expert Interface to view the FORWARDING
screen.
ADVANCED: FORWARDING Screen

port forwarding
Port forwarding is used to set up public services on a network, such as Web, FTP, or
e-mail servers. When Internet users make certain requests to your network, the
Gateway forwards them to specific computers equipped to handle the requests. For

advanced

example, if you set port number 80 (HTTP) to be forwarded to IP address
192.168.1.2, then all HTTP requests from outside users will be forwarded to
192.168.1.2.
Enter a valid IP address. You may need to establish a static IP address with your
Internet provider in order to properly run an Internet server. For added security,
Internet users are able to communicate with the server but will not actually be
connected. The packets are forwarded through the Gateway.
To add a server using forwarding:
1 Enter the range of port numbers and select the protocol used by the server.
2 Enter the IP address of the server that you want the Internet users to be able to
access. Refer to your software documentation for more information concerning
which service port settings may need to be changed, if any.

Close Window to return to the Forwarding tab.
The Gateway will forward incoming packets to the LAN host.

wireless gateway

dynamic routing
Dynamic routing allows the Gateway to automatically adjust to physical changes in
network layout. The Gateway, using the dynamic Routing Information Protocol (RIP)
protocol, determines the route that the network packets take based on the fewest
number of hops between source and destination. The RIP protocol regularly
broadcasts routing information to other routers on the network.
Select the Dyn. Routes tab of the Expert Interface to view the DYNAMIC
ROUTING screen.
ADVANCED: DYNAMIC ROUTING Screen

To view the current routing table:
Click Show Routing Table to view all valid dynamic route entries in use.
To set up Dynamic Routing:
1 In the Working Mode field, select Gateway if your Gateway is hosting your
network's connection to the Internet. Select Router if the router exists on a

advanced

network with other routers, including a separate network gateway that handles
the Internet connection.
2 In the TX field, choose the protocol to transmit data on the network.
3 In the RX field, choose the protocol to receive data from the network.
4 Click Apply to save changes.

static routing
If your Gateway is connected to more than one network, it may be necessary to set
up a static route between them. Static routing determines the path that data follows
over your network before and after it passes through your Gateway. You can use
static routing to allow different IP domain users to access the Internet through this
device.
Warning: This is an advanced feature. Please proceed with caution.

This Gateway is also capable of dynamic routing. To view the Dynamic Routing
screen, select the Dyn. Routes tab. In many cases, it is better to use dynamic
routing because it allows the Gateway to automatically adjust to physical changes
in the network layout. In order to use static routing, the Gateway's DHCP settings

supports up to 20 static route entries.
2 Enter the following data to create a new static route:

advanced

❑

Destination LAN IP: Enter the IP address of the remote network or host for
which you wish to create a static route. If you are building a route to an
entire network set the network portion of the IP address to zero (0). For
example, the Gateway’s standard IP address is 192.168.1.1. Based on this
address, the address of the network to which the Gateway is connected is
192.168.1, with the last digit (1, in this case) determining the Gateway’s
place on the network. Enter 192.168.1.0 for the IP address if you want to
route to the Gateway’s entire network.

❑

Subnet Mask: Enter the subnet mask used on the destination LAN's IP
domain. The subnet mask (also known as the network mask) identifies which
portion of an IP address is the network portion and which is the host
portion. For example, if the subnet mask is 255.255.255.0, the first three
numbers (255) identify this particular network, while the last digit (1 to 254)
identifies the specific host.

❑

Default Gateway: If the Gateway is the main IP router to connect your
network to the Internet, then the default gateway IP address and your
Gateway IP address are the same. If you have another router handling your
network's Internet connection, enter the IP address of your main Internet
router here instead.

❑

Hop Count: Specifies the number of nodes a data packet passes through
before reaching its destination. A node is any device on the network
(switches and PCs, for example).

❑

Interface: Specifies whether your network is on the internal LAN or the
WAN (the Internet). Select one of the following:
❑

LAN if you are connecting to a subnetwork.

❑

WAN if you are connecting to a network through the Internet.

3 Click Apply to save changes.

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

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).

wireless gateway

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.

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.

glossary

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)

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.

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.
