CHAPTER 14
DHCP Server
14.1 Overview
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients to
obtain TCP/IP configuration at start-up from a server. You can configure the NBG5615’s LAN as a
DHCP server or disable it. When configured as a server, the NBG5615 provides the TCP/IP
configuration for the clients. If DHCP service is disabled, you must have another DHCP server on
your LAN, or else the computer must be manually configured.
14.1.1 What You Can Do
•Use the General screen to enable the DHCP server (Section 14.2 on page 133).
•Use the Advanced screen to assign IP addresses on the LAN to specific individual computers
based on their MAC Addresses (Section 14.3 on page 134).
•Use the Client List screen to view the current DHCP client information (Section 14.4 on page
136).
14.1.2 What You Need To Know
The following terms and concepts may help as you read through this chapter.
MAC Addresses
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address is
assigned at the factory and consists of six pairs of hexadecimal characters, for example,
00:A0:C5:00:00:02. Find out the MAC addresses of your network devices if you intend to add them
to the DHCP Client List screen.

CHAPTER 15
NAT
15.1 Overview
NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host in
a packet. For example, the source address of an outgoing packet, used within one network is
changed to a different IP address known within another network.
The figure below is a simple illustration of a NAT network. You want to assign ports 21-25 to one
FTP, Telnet and SMTP server (A in the example), port 80 to another (B in the example) and assign
a default server IP address of 192.168.1.35 to a third (C in the example).
You assign the LAN IP addresses to the devices (A to D) connected to your NBG5615. The ISP
assigns the WAN IP address. The NAT network appears as a single host on the Internet. All traffic
coming from A to D going out to the Internet use the IP address of the NBG5615, which is
192.168.1.1.
Figure 81 NAT Example
This chapter discusses how to configure NAT on the NBG5615.
Note: You must create a firewall rule in addition to setting up NAT, to allow traffic from
the WAN to be forwarded through the NBG5615.
15.1.1 What You Can Do
•Use the General screen to enable NAT (Section 15.2 on page 141).

•Use the Port Forw arding screen to set a default server and change your NBG5615’s port
forwarding settings to forward incoming service requests to the server(s) on your local network
(Section 15.3 on page 142).
•Use the Port Trigger screen to change your NBG5615’s trigger port settings (Section 15.5.3 on
page 147).
15.1.2 What You Need To Know
The following terms and concepts may help as you read through this chapter.
Inside/Outside
This denotes where a host is located relative to the NBG5615, for example, the computers of your
subscribers are the inside hosts, while the web servers on the Internet are the outside hosts.
Global/Local
This denotes the IP address of a host in a packet as the packet traverses a router, for example, the
local address refers to the IP address of a host when the packet is in the local network, while the
global address refers to the IP address of the host when the same packet is traveling in the WAN
side.
Note: Inside/outside refers to the location of a host, while global/local refers to the IP
address of a host used in a packet.
An inside local address (ILA) is the IP address of an inside host in a packet when the packet is still
in the local network, while an inside global address (IGA) is the IP address of the same inside host
when the packet is on the WAN side. The following table summarizes this information.
Note: NAT never changes the IP address (either local or global) of an outside host.
What NAT Does
In the simplest form, NAT changes the source IP address in a packet received from a subscriber
(the inside local address) to another (the inside global address) before forwarding the packet to the
WAN side. When the response comes back, NAT translates the destination address (the inside
global address) back to the inside local address before forwarding it to the original inside host. Note
that the IP address (either local or global) of an outside host is never changed.
The global IP addresses for the inside hosts can be either static or dynamically assigned by the ISP.
In addition, you can designate servers, for example, a web server and a telnet server, on your local
Table 55 NAT Definitions
ITEM DESCRIPTION
Inside This refers to the host on the LAN.
Outside This refers to the host on the WAN.
Local This refers to the packet address (source or destination) as the packet travels on the LAN.
Global This refers to the packet address (source or destination) as the packet travels on the WAN.

NBG5615 User’s Guide 141
network and make them accessible to the outside world. If you do not define any servers , NAT
offers the additional benefit of firewall protection. With no servers defined, your NBG5615 filters out
all incoming inquiries, thus preventing intruders from probing your network. For more information
on IP address translation, refer to RFC 1631, The I P Network Address Translator (NAT).
How NAT Works
Each packet has two addresses – a source address and a destination address. For outgoing packets,
the ILA (Inside Local Address) is the source address on the LAN, and the IGA (Inside Global
Address) is the source address on the WAN. For incoming packets, the ILA is the destination
address on the LAN, and the IGA is the destination address on the WAN. NAT maps private (local)
IP addresses to globally unique ones required for communication with hosts on other networks. It
replaces the original IP source address in each packet and then forwards it to the Internet. The
NBG5615 keeps track of the original addresses and port numbers so incoming reply packets can
have their original values restored. The following figure illustrates this.

15.3 Port Forwarding Screen
Use this screen to forward incoming service requests to the server(s) on your local network and set
a default server. You may enter a single port number or a range of port numbers to be forwarded,
and the local IP address of the desired server. The port number identifies a service; for example,
web service is on port 80 and FTP on port 21. In some cases, such as for unknown services or
where one server can support more than one service (for example both FTP and web service), it
might be better to specify a range of port numbers.
In addition to the servers for specified services, NAT supports a default server. A service request
that does not have a server explicitly designated for it is forwarded to the default server. If the
default is not defined, the service request is simply discarded.
Note: Many residential broadband ISP accounts do not allow you to run any server
processes (such as a Web or FTP server) from your location. Your ISP may
periodically check for servers and may suspend your account if it discovers any
active services at your location. If you are unsure, refer to your ISP.
Port forwarding allows you to define the local servers to which the incoming services will be
forwarded. To change your NBG5615’s port forwarding settings, click Netw ork > NAT > Port
Forw arding. The screen appears as shown.
Note: If you do not assign a Default Server, the NBG5615 discards all packets received
for ports that are not specified in this screen or remote management.
Refer to Appendix C on page 249 for port numbers commonly used for particular services.

15.5 Technical Reference
The following section contains additional technical information about the NBG5615 features
described in this chapter.
15.5.1 NATPort Forwarding: Services and Port Numbers
A port forwarding set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP,
that you can make accessible to the outside world even though NAT makes your whole inside
network appear as a single machine to the outside world.
Use the Port Forw arding screen to forward incoming service requests to the server(s) on your
local network. You may enter a single port number or a range of port numbers to be forwarded, and
the local IP address of the desired server. The port number identifies a service; for example, web
service is on port 80 and FTP on port 21. In some cases, such as for unknown services or where one
server can support more than one service (for example both FTP and web service), it might be
better to specify a range of port numbers.
In addition to the servers for specified services, NAT supports a default server. A service request
that does not have a server explicitly designated for it is forwarded to the default server. If the
default is not defined, the service request is simply discarded.
Note: Many residential broadband ISP accounts do not allow you to run any server
processes (such as a Web or FTP server) from your location. Your ISP may
periodically check for servers and may suspend your account if it discovers any
active services at your location. If you are unsure, refer to your ISP.
15.5.2 NAT Port Forwarding Example
Let's say you want to assign ports 21-25 to one FTP, Telnet and SMTP server (A in the example),
port 80 to another (B in the example) and assign a default server IP address of 192.168.1.35 to a
third (C in the example). You assign the LAN IP addresses and the ISP assigns the WAN IP address.
The NAT network appears as a single host on the Internet.
Figure 87 Multiple Servers Behind NAT Example
Chapter 15 NAT
NBG5615 User’s Guide 147
15.5.3 Trigger Port Forwarding
Some services use a dedicated range of ports on the client side and a dedicated range of ports on
the server side. With regular port forwarding you set a forwarding port in NAT to forward a service
(coming in from the server on the WAN) to the IP address of a computer on the client side (LAN).
The problem is that port forwarding only forwards a service to a single LAN IP address. In order to
use the same service on a different LAN computer, you have to manually replace the LAN
computer's IP address in the forwarding port with another LAN computer's IP address.
Trigger port forwarding solves this problem by allowing computers on the LAN to dynamically take
turns using the service. The NBG5615 records the IP address of a LAN computer that sends traffic
to the WAN to request a service with a specific port number and protocol (a "trigger" port). When
the NBG5615's WAN port receives a response with a specific port number and protocol ("incoming"
port), the NBG5615 forwards the traffic to the LAN IP address of the computer that sent the
request. After that computer’s connection for that service closes, another computer on the LAN can
use the service in the same manner. This way you do not need to configure a new IP address each
time you want a different LAN computer to use the application.
15.5.4 Trigger Port Forwarding Example
The following is an example of trigger port forwarding.
Figure 88 Trigger Port Forwarding Process: Example
1Jane requests a file from the Real Audio server (port 7070).
2Port 7070 is a “trigger” port and causes the NBG5615 to record Jane’s computer IP address. The
NBG5615 associates Jane's computer IP address with the "incoming" port range of 6970-7170.
3The Real Audio server responds using a port number ranging between 6970-7170.
4The NBG5615 forwards the traffic to Jane’s computer IP address.
5Only Jane can connect to the Real Audio server until the connection is closed or times out. The
NBG5615 times out in three minutes with UDP (User Datagram Protocol), or two hours with TCP/IP
(Transfer Control Protocol/Internet Protocol).

Static Route
17.1 Overview
This chapter shows you how to configure static routes for your NBG5615.
The NBG5615 usually uses the default gateway to route outbound traffic from computers on the
LAN to the Internet. To have the NBG5615 send data to devices not reachable through the default
gateway, use static routes.
For example, the next figure shows a computer (A) connected to the NBG5615’s LAN interface. The
NBG5615 routes most traffic from A to the Internet through the NBG5615’s default gateway (R1 ).
You create one static route to connect to services offered by your ISP behind router R2 . You create
another static route to communicate with a separate network behind a router R3 connected to the
LAN.

Firewall
18.1 Overview
Use these screens to enable and configure the firewall that protects your NBG5615 and your LAN
from unwanted or malicious traffic.
Enable the firewall to protect your LAN computers from attacks by hackers on the Internet and
control access between the LAN and WAN. By default the firewall:
• allows traffic that originates from your LAN computers to go to all of the networks.
• blocks traffic that originates on the other networks from going to the LAN.
The following figure illustrates the default firewall action. User A can initiate an IM (Instant
Messaging) session from the LAN to the WAN (1). Return traffic for this session is also allowed (2).
However other traffic initiated from the WAN is blocked (3 and 4).

What is a Firewall?
Originally, the term “firewall” referred to a construction technique designed to prevent the spread of
fire from one room to another. The networking term "firewall" is a system or group of systems that
enforces an access-control policy between two networks. It may also be defined as a mechanism
used to protect a trusted network from a network that is not trusted. Of course, firewalls cannot
solve every security problem. A firewall is one of the mechanisms used to establish a network
security perimeter in support of a network security policy. It should never be the only mechanism or
method employed. For a firewall to guard effectively, you must design and deploy it appropriately.
This requires integrating the firewall into a broad information-security policy. In addition, specific
policies must be implemented within the firewall itself.
Stateful Inspection Firewall
Stateful inspection firewalls restrict access by screening data packets against defined access rules.
They make access control decisions based on IP address and protocol. They also "inspect" the
session data to assure the integrity of the connection and to adapt to dynamic protocols. These
firewalls generally provide the best speed and transparency; however, they may lack the granular
application level access control or caching that some proxies support. Firewalls, of one type or
another, have become an integral part of standard security solutions for enterprises.
About the NBG5615 Firewall
The NBG5615’s firewall feature physically separates the LAN and the WAN and acts as a secure
gateway for all data passing between the networks.
It is a stateful inspection firewall and is designed to protect against Denial of Service attacks when
activated (click the General tab under Firew all and then click the Enable Firew all check box).
The NBG5615's purpose is to allow a private Local Area Network (LAN) to be securely connected to
the Internet. The NBG5615 can be used to prevent theft, destruction and modification of data, as
well as log events, which may be important to the security of your network.
The NBG5615 is installed between the LAN and a broadband modem connecting to the Internet.
This allows it to act as a secure gateway for all data passing between the Internet and the LAN.
The NBG5615 has one Ethernet WAN port and four Ethernet LAN ports, which are used to physically
separate the network into two areas.The WAN (Wide Area Network) port attaches to the broadband
(cable or DSL) modem to the Internet.
The LAN (Local Area Network) port attaches to a network of computers, which needs security from
the outside world. These computers will have access to Internet services such as e-mail, FTP and
the World Wide Web. However, "inbound access" is not allowed (by default) unless the remote host
is authorized to use a specific service.
Guidelines For Enhancing Security With Your Firewall
1Change the default password via Web Configurator.
2Think about access control before you connect to the network in any way, including attaching a
modem to the port.
3Limit who can access your router.
Chapter 18 Firewall
NBG5615 User’s Guide 157
4Don't enable any local service (such as NTP) that you don't use. Any enabled service could present
a potential security risk. A determined hacker might be able to find creative ways to misuse the
enabled services to access the firewall or the network.
5For local services that are enabled, protect against misuse. Protect by configuring the services to
communicate only with specific peers, and protect by configuring rules to block packets for the
services at specific interfaces.
6Protect against IP spoofing by making sure the firewall is active.
7Keep the firewall in a secured (locked) room.

Content Filtering
19.1 Overview
This chapter provides a brief overview of content filtering using the embedded web GUI.
Internet content filtering allows you to create and enforce Internet access policies tailored to your
needs. Content filtering is the ability to block certain web features or specific URL keywords.
19.1.1 What You Need To Know
The following terms and concepts may help as you read through this chapter.
Content Filtering Profiles
Content filtering allows you to block certain web features, such as cookies, and/or block access to
specific web sites. For example, you can configure one policy that blocks John Doe’s access to arts
and entertainment web pages.
A content filtering profile conveniently stores your custom settings for the following features.
Keyword Blocking URL Checking
The NBG5615 checks the URL’s domain name (or IP address) and file path separately when
performing keyword blocking.
The URL’s domain name or IP address is the characters that come before the first slash in the URL.
For example, with the URL www.zyxel.com.tw/news/pressroom.php, the domain name is
www.zyxel.com.tw.
The file path is the characters that come after the first slash in the URL. For example, with the URL
www.zyxel.com.tw/news/pressroom.php, the file path is news/pressroom.php.
Since the NBG5615 checks the URL’s domain name (or IP address) and file path separately, it will
not find items that go across the two. For example, with the URL www.zyxel.com.tw/news/
pressroom.php, the NBG5615 would find “tw” in the domain name (www.zyxel.com.tw). It would
also find “news” in the file path (news/pressroom.php) but it would not find “tw/news”.

ActiveX A tool for building dynamic and active Web pages and distributed object applications.
When you visit an ActiveX Web site, ActiveX controls are downloaded to your browser,
where they remain in case you visit the site again.
Java A programming language and development environment for building downloadable Web
components or Internet and intranet business applications of all kinds.
Cookies Used by Web servers to track usage and provide service based on ID.
Web Proxy A server that acts as an intermediary between a user and the Internet to provide
security, administrative control, and caching service. When a proxy server is located on
the WAN it is possible for LAN users to circumvent content filtering by pointing to this
proxy server.
Enable URL
Keyword Blocking
The NBG5615 can block Web sites with URLs that contain certain keywords in the domain
name or IP address. For example, if the keyword "bad" was enabled, all sites containing
this keyword in the domain name or IP address will be blocked, e.g., URL http://
www.website.com/bad.html would be blocked.
Select this check box to enable this feature.
Keyword Type a keyword in this field. You may use any character (up to 64 characters). Wildcards
are not allowed. You can also enter a numerical IP address.
Add Click Add after you have typed a keyword.
Repeat this procedure to add other keywords. Up to 64 keywords are allowed.
When you try to access a web page containing a keyword, you will get a message telling
you that the content filter is blocking this request.

19.3 Technical Reference
The following section contains additional technical information about the NBG5615 features
described in this chapter.
19.3.1 Customizing Keyword Blocking URL Checking
You can use commands to set how much of a website’s URL the content filter is to check for
keyword blocking. See the appendices for information on how to access and use the command
interpreter.
Domain Name or IP Address URL Checking
By default, the NBG5615 checks the URL’s domain name or IP address when performing keyword
blocking.
This means that the NBG5615 checks the characters that come before the first slash in the URL.
For example, with the URL www.zyxel.com.tw/news/pressroom.php, content filtering only searches
for keywords within www.zyxel.com.tw.
Full Path URL Checking
Full path URL checking has the NBG5615 check the characters that come before the last slash in the
URL.
For example, with the URL www.zyxel.com.tw/news/pressroom.php, full path URL checking
searches for keywords within www.zyxel.com.tw/news/.
Use the ip urlfilter customize actionFlags 6 [disable | enable] command to extend (or
not extend) the keyword blocking search to include the URL's full path.
File Name URL Checking
Filename URL checking has the NBG5615 check all of the characters in the URL.
For example, filename URL checking searches for keywords within the URL www.zyxel.com.tw/
news/pressroom.php.
Keyword List This list displays the keywords already added.

Bandwidth Management
20.1 Overview
This chapter contains information about configuring bandwidth management and editing rules.
ZyXEL’s Bandwidth Management allows you to specify bandwidth management rules based on an
application.
In the figure below, uplink traffic goes from the LAN device (A) to the WAN device (B). Bandwidth
management is applied before sending the packets out to the WAN. Downlink traffic comes back
from the WAN device (B) to the LAN device (A). Bandwidth management is applied before sending
the traffic out to LAN.
Figure 97 Bandwidth Management Example
You can allocate specific amounts of bandwidth capacity (bandwidth budgets) to individual
applications (like VoIP, Web, FTP, and E-mail for example).
20.2 What You Can Do

WWW The World Wide Web (WWW) is an Internet system to distribute graphical, hyper-linked
information, based on Hyper Text Transfer Protocol (HTTP) - a client/server protocol for
the World Wide Web. The Web is not synonymous with the Internet; rather, it is just one
service on the Internet. Other services on the Internet include Internet Relay Chat and
Newsgroups. The Web is accessed through use of a browser.
E-Mail Electronic mail consists of messages sent through a computer network to specific groups
or individuals. Here are some default ports for e-mail:
VoIP (SIP) Sending voice signals over the Internet is called Voice over IP or VoIP. Session Initiated
Protocol (SIP) is an internationally recognized standard for implementing VoIP. SIP is an
application-layer control (signaling) protocol that handles the setting up, altering and
tearing down of voice and multimedia sessions over the Internet.
SIP is transported primarily over UDP but can also be transported over TCP.
BitTorrent BitTorrent is a free P2P (peer-to-peer) sharing tool allowing you to distribute large
software and media files. BitTorrent requires you to search for a file with a searching
engine yourself. It distributes files by corporation and trading, that is, the client
downloads the file in small pieces and share the pieces with other peers to get other half
of the file.

22.1 Overview
This chapter introduces the UPnP feature in the web configurator.
Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP for
simple peer-to-peer network connectivity between devices. A UPnP device can dynamically join a
network, obtain an IP address, convey its capabilities and learn about other devices on the network.
In turn, a device can leave a network smoothly and automatically when it is no longer in use.
22.2 What You Need to Know
UPnP hardware is identified as an icon in the Network Connections folder (Windows XP). Each UPnP
compatible device installed on your network will appear as a separate icon. Selecting the icon of a
UPnP device will allow you to access the information and properties of that device.
22.2.1 NAT Traversal
UPnP NAT traversal automates the process of allowing an application to operate through NAT. UPnP
network devices can automatically configure network addressing, announce their presence in the
network to other UPnP devices and enable exchange of simple product and service descriptions.
NAT traversal allows the following:
• Dynamic port mapping
• Learning public IP addresses
• Assigning lease times to mappings
Windows Messenger is an example of an application that supports NAT traversal and UPnP.
See the NAT chapter for more information on NAT.
22.2.2 Cautions with UPnP
The automated nature of NAT traversal applications in establishing their own services and opening
firewall ports may present network security issues. Network information and configuration may also
be obtained and modified by users in some network environments.
When a UPnP device joins a network, it announces its presence with a multicast message. For
security reasons, the NBG5615 allows multicast messages on the LAN only.

CHAPTER 23
USB Media Sharing
23.1 Overview
This chapter describes how to configure the media sharing settings on the NBG5615.
Note: The read and write performance may be affected by amount of file-sharing traffic
on your network, type of connected USB device and your USB version (1.1 or 2.0).
Media Server
You can set up your NBG5615 to act as a media server to provide media (like video) to DLNA-
compliant players, such as Windows Media Player, ZyXEL DMAs (Digital Media Adapters), Xboxes or
PS3s. The media server and clients must have IP addresses in the same subnet.
The NBG5615 media server enables you to:
• Publish all folders for everyone to play media files in the USB storage device connected to the
NBG5615.
• Use hardware-based media clients like the DMA-2500 to play the files.
Note: Anyone on your network can play the media files in the published folders. No user
name and password nor other form of security is required.
The following figure is an overview of the NBG5615’s media server feature. DLNA devices A and B
can access and play files on a USB device (C) which is connected to the NBG5615 (D).

users on your network.
The following figure is an overview of the NBG5615’s file-sharing server feature. Computers A and
B can access files on a USB device (C) which is connected to the NBG5615 (D).
Figure 116 File Sharing Overview
23.2 What You Can Do
•Use the DLNA screen to use the NBG5615 as a media server and allow DLNA-compliant devices
to play media files stored in the attached USB device (Section 23.5 on page 186).
•Use the SAMBA screen to enable file-sharing via the NBG5615 using Windows Explorer or the
workgroup name. This screen also allow you to configure the workgroup name and create user
accounts (Section 23.6 on page 186).
•Use the FTP screen to allow file sharing via the NBG5615 using FTP and create user accounts
(Section 23.7 on page 188).
23.3 What You Need To Know
DLNA
The Digital Living Network Alliance (DLNA) is a group of personal computer and electronics
companies that works to make products compatible in a home network. DLNA clients play files
stored on DLNA servers. The NBG5615 can function as a DLNA-compliant media server and stream
files to DLNA-compliant media clients without any configuration.

Workgroup name
This is the name given to a set of computers that are connected on a network and share resources
such as a printer or files. Windows automatically assigns the workgroup name when you set up a
network.
File Systems
A file system is a way of storing and organizing files on your hard drive and storage device. Often
different operating systems such as Windows or Linux have different file systems. The file-sharing
feature on your NBG5615 supports New Technology File System (NTFS), File Allocation Table (FAT)
and FAT32 file systems.
Windows/CIFS
Common Internet File System (CIFS) is a standard protocol supported by most operating systems
in order to share files across the network.
CIFS runs over TCP/IP but uses the SMB (Server Message Block) protocol found in Microsoft
Windows for file and printer access; therefore, CIFS will allow all applications, not just Web
browsers, to open and share files across the Internet.
The NBG5615 uses Common Internet File System (CIFS) protocol for its file sharing functions. CIFS
compatible computers can access the USB file storage devices connected to the NBG5615. CIFS
protocol is supported on Microsoft Windows, Linux Samba and other operating systems (refer to
your systems specifications for CIFS compatibility).
Samba
SMB is a client-server protocol used by Microsoft Windows systems for sharing files, printers, and
so on.
Samba is a free SMB server that runs on most Unix and Unix-like systems. It provides an
implementation of an SMB client and server for use with non-Microsoft operating systems.
File Transfer Protocol
This is a method of transferring data from one computer to another over a network such as the
Internet.
23.4 Before You Begin
Make sure the NBG5615 is connected to your network and turned on.
1Connect the USB device to one of the NBG5615’s USB ports.
2The NBG5615 detects the USB device and makes its contents available for browsing. If you are
connecting a USB hard drive that comes with an external power supply, make sure it is connected
to an appropriate power source that is on.

When you change from router mode to AP mode, your computer must have an IP address in the
range between “192.168.1.3” and “192.168.1.254”.
Refer to Appendix B on page 221 for instructions on how to change your computer’s IP address.
What factors may cause intermittent or unstabled wireless connection? How can I solve this
problem?
The following factors may cause interference:
• Obstacles: walls, ceilings, furniture, and so on.
• Building Materials: metal doors, aluminum studs.
• Electrical devices: microwaves, monitors, electric motors, cordless phones, and other wireless
devices.
To optimize the speed and quality of your wireless connection, you can:
• Move your wireless device closer to the AP if the signal strength is low.
• Reduce wireless interference that may be caused by other wireless networks or surrounding
wireless electronics such as cordless phones.
• Place the AP where there are minimum obstacles (such as walls and ceilings) between the AP and
the wireless client.
• Reduce the number of wireless clients connecting to the same AP simultaneously, or add
additional APs if necessary.
• Try closing some programs that use the Internet, especially peer-to-peer applications. If the
wireless client is sending or receiving a lot of information, it may have too many programs open
that use the Internet.
