NBG5615 User’s Guide 133CHAPTER 14DHCP Server14.1 OverviewDHCP (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 KnowThe following terms and concepts may help as you read through this chapter.MAC AddressesEvery 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.14.2 DHCP Server General ScreenUse this screen to enable the DHCP server.

NBG5615 User’s Guide 139CHAPTER 15NAT15.1 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 ExampleThis 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).A: 192.168.1.33B: 192.168.1.34C: 192.168.1.35IP address 192.168.1.1WANLANassigned by ISPFTP, Telnet, SNMPPort 80Ports 21 to 25

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 DoesIn 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 DefinitionsITEM DESCRIPTIONInside 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.
Chapter 15 NATNBG5615 User’s Guide 141network 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 WorksEach 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.Figure 82 How NAT Works15.2 GeneralUse this screen to enable NAT and set a default server. Click Netw ork > NAT to open the General screen.Figure 83 Network > NAT > General
Chapter 15 NATNBG5615 User’s Guide142The following table describes the labels in this screen.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.Table 56 Network > NAT > GeneralLABEL DESCRIPTIONNetwork Address Translation (NAT)Network Address Translation (NAT) allows the translation of an Internet protocol address used within one network (for example a private IP address used in a local network) to a different IP address known within another network (for example a public IP address used on the Internet).

Chapter 15 NATNBG5615 User’s Guide14615.5 Technical ReferenceThe following section contains additional technical information about the NBG5615 features described in this chapter.15.5.1 NATPort Forwarding: Services and Port NumbersA 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 ExampleLet'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 NATNBG5615 User’s Guide 14715.5.3 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: Example1Jane 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). Jane’s com puterReal Audio ServerPort 707 0
Chapter 15 NATNBG5615 User’s Guide14815.5.5 Two Points To Remember About Trigger Ports1Trigger events only happen on data that is coming from inside the NBG5615 and going to the outside.2If an application needs a continuous data stream, that port (range) will be tied up so that another computer on the LAN can’t trigger it.

NBG5615 User’s Guide 151CHAPTER 17Static Route17.1 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.Figure 90 Example of Static Routing Topology17.2 IP Static Route Screen Click Netw ork > Static Route to open the Static Route screen.

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).Figure 93 Default Firewall Action18.1.1 What You Can Do•Use the General screen to enable or disable the NBG5615’s firewall (Section 18.2 on page 157).•Use the Services screen enable service blocking, enter/delete/modify the services you want to block and the date/time you want to block them (Section 18.3 on page 157).18.1.2 What You Need To KnowThe following terms and concepts may help as you read through this chapter.WANLAN3412A
Chapter 18 FirewallNBG5615 User’s Guide156What 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 FirewallThe 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 Firewall1Change 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.

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. 18.2 General Screen Use this screen to enable or disable the NBG5615’s firewall, and set up firewall logs.

NBG5615 User’s Guide 161CHAPTER 19Content Filtering19.1 OverviewThis 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 KnowThe following terms and concepts may help as you read through this chapter.Content Filtering ProfilesContent 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 CheckingThe 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”.19.2 Content FilterUse this screen to restrict web features, add keywords for blocking and designate a trusted computer. Click Security > Content Filter to open the Content Filter screen.

This allows the trusted computer to have full access to all features that are configured to be blocked by content filtering.Leave this field blank to have no trusted computers.Restrict Web FeaturesSelect the box(es) to restrict a feature. When you download a page containing a restricted feature, that part of the web page will appear blank or grayed out.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 BlockingThe 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.

Table 70 Media Bandwidth Management Setup: ServicesSERVICE DESCRIPTIONFTP File Transfer Program enables fast transfer of files, including large files that may not be possible by e-mail.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.Gaming Online gaming services lets you play multiplayer games on the Internet via broadband technology. As of this writing, your NBG5615 supports Xbox, Playstation, Battlenet and MSN Game Zone.

NBG5615 User’s Guide 177CHAPTER 22Universal Plug-and-Play (UPnP)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 KnowUPnP 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 TraversalUPnP 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 mappingsWindows 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 UPnPThe 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 22 Universal Plug-and-Play (UPnP)NBG5615 User’s Guide178All UPnP-enabled devices may communicate freely with each other without additional configuration.

Computers A and B can access files on a USB device (C) which is connected to the NBG5615 (D).Figure 116 File Sharing Overview23.2 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 KnowDLNAThe 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. ABCD
Chapter 23 USB Media SharingNBG5615 User’s Guide 185Workgroup nameThis 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 SystemsA 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/CIFSCommon 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). SambaSMB 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 BeginMake 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.

The password is “1234”.If the NBG5615 does not restart automatically, disconnect and reconnect the NBG5615’s power. Then, follow the directions above again.25.6 Wireless ConnectionsI cannot access the NBG5615 or ping any computer from the WLAN.1Make sure the wireless LAN is enabled on the NBG5615.2Make sure the wireless adapter on your computer is working properly.3Make sure the wireless adapter installed on your computer is IEEE 802.11 compatible and supports the same wireless standard as the NBG5615.4Make sure your computer (with a wireless adapter installed) is within the transmission range of the NBG5615.5Check that both the NBG5615 and the wireless adapter on your computer are using the same wireless and wireless security settings.6Make sure traffic between the WLAN and the LAN is not blocked by the firewall on the NBG5615.
Chapter 25 TroubleshootingNBG5615 User’s Guide2087Make sure you allow the NBG5615 to be remotely accessed through the WLAN interface. Check your remote management settings.• See the chapter on Wireless LAN in the User’s Guide for more information.I set up URL keyword blocking, but I can still access a website that should be blocked.Make sure that you select the Enable URL Keyw ord Blocking check box in the Content Filtering screen. Make sure that the keywords that you type are listed in the Keyw ord List. If a keyword that is listed in the Keyw ord List is not blocked when it is found in a URL, customize the keyword blocking using commands. See the Customizing Keyword Blocking URL Checking section in the Content Filtering chapter.I cannot access the Web Configurator after I switched to AP mode.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.
Chapter 25 TroubleshootingNBG5615 User’s Guide 209• Position the antennas for best reception. If the AP is placed on a table or floor, point the antennas upwards. If the AP is placed at a high position, point the antennas downwards.
