Wireless LAN Networking This section provides background information on wireless LAN networking technology. Consult the Glossary for definitions of the terminology used in this section. THE INFORMATION IN THIS SECTION IS FOR YOUR REFERENCE. CHANGING NETWORK SETTINGS AND PARTICULARLY SECURITY SETTTINGS SHOULD ONLY BE DONE BY AN AUTHORIZED ADMINISTRATOR. Transmission Rate (Transfer Rate) The WRT-383U provides various transmission (data) rate options for you to select.
sometimes be referred to as an Independent Basic Service Set (IBSS). To set up an ad-hoc network, configure all the stations in ad-hoc mode. Use the same SSID and channel for each station.
When a number of wireless stations are connected using a single access point, you have a Basic Service Set (BSS). In the ESS diagram below, communication is done through the access points, which relay data packets to other wireless stations or devices connected to the wired network. Wireless stations can then access resources, such as a printer, on the wired network.
In an ESS environment, users are able to move from one access point to another without losing the connection. In the diagram below, when the user moves from BSS (1) to BSS (2) the WLAN client devices automatically switches to the channel used in BSS (2).

Installation Considerations The WRT-383U 11n (Draft) Wireless Router lets you access your network, using a wireless connection, from virtually anywhere within its operating range. Keep in mind, however, that the number, thickness and location of walls, ceilings, or other objects that the wireless signals must pass through, may limit the range. Typical ranges vary depending on the types of materials and background RF (radio frequency) noise in your home or business.
Using the Configuration Menu Whenever you want to configure your WRT-390U, you can access the Configuration Menu through your PC by opening the Web-browser and typing in the IP Address of the WRT-383U. The WRT-383U’s default IP Address is http://192.168.0.1 Open the Web browser. Type in the IP Address of the Router (http://192.168.0.1). If you have changed the default IP Address assigned to the WRT-390U, make sure to enter the correct IP Address. Select admin in the User Name field.
Basic The Basic tab provides the following configuration options: Internet Connection, Wireless Settings, Network Settings Basic_ Internet Connection Internet Connection Setup Wizard If you are new to networking and have never configured a router before, click on Setup Wizard and the router will guide you through a few simple steps to get your network up and running.
Basic_ Wireless Settings The wireless section is used to configure the wireless settings for your router. Note that changes made in this section may also need to be duplicated on wireless clients that you want to connect to your wireless network. To protect your privacy, use the wireless security mode to configure the wireless security features. This device supports three wireless security modes including: WEP, WPA-Personal, and WPA-Enterprise. WEP is the original wireless encryption standard.
If you select this option, the router automatically finds the channel with least interference and uses that channel for wireless networking. If you disable this option, the router uses the channel that you specify with the following Wireless Channel option. Wireless Channel A wireless network uses specific channels in the wireless spectrum to handle communication between clients. Some channels in your area may have interference from other electronic devices.

WAN Port Mode This option controls how the device reacts to traffic on the WAN connector. In this case the term "port" refers to the Ethernet connectors on the device. Router Mode Select this option if the WAN port is connected to the Internet. The device functions as a NAT router. Bridge Mode Select this option if the device is connected to a local network downstream from another router.
server. DNS Relay When DNS Relay is enabled, the router plays the role of a DNS server. DNS requests sent to the router are forwarded to the ISP's DNS server. This provides a constant DNS address that LAN computers can use, even when the router obtains a different DNS server address from the ISP upon re-establishing the WAN connection. You should disable DNS relay if you implement a LAN-side DNS server as a virtual server.
Example: Your router uses 192.168.0.1 for the IP address. You've assigned a computer that you want to designate as a Web server with a static IP address of 192.168.0.3. You've assigned another computer that you want to designate as an FTP server with a static IP address of 192.168.0.4. Therefore the starting IP address for your DHCP IP address range needs to be 192.168.0.5 or greater. Example: Suppose you configure the DHCP Server to manage addresses From 192.168.0.100 To 192.168.0.199. This means that 192.
NetBIOS Registration mode Indicates how network hosts are to perform NetBIOS name registration and discovery. H-Node, this indicates a Hybrid-State of operation. First WINS servers are tried, if any, followed by local network broadcast. This is generally the preferred mode if you have configured WINS servers. M-Node (default), this indicates a Mixed-Mode of operation.
Mac OS X Go to the Apple Menu, select System Preferences, select Network, and select the Ethernet Adapter connecting to the router. Select the Ethernet button and the Ethernet ID will be listed. This is the same as the MAC address. Enable Specifies whether the entry will be active or inactive. Save/Update Record the changes you have made into the following list.

activate or de-activate the entry. An entry can be changed by clicking the Edit icon or can be deleted by clicking the Delete icon. When you click the Edit icon, the item is highlighted, and the "Edit Virtual Servers" section is activated for editing. Note: You might have trouble accessing a virtual server using its public identity (WAN-side IP-address of the gateway or its dynamic DNS name) from a machine on the LAN. Your requests may not be looped back or you may be redirected to the "Forbidden" page.
Advanced_Special Applications An application rule is used to open single or multiple ports on your router when the router senses data sent to the Internet on a "trigger" port or port range. An application rule applies to all computers on your internal network. Add/Edit Application Rule Example: You need to configure your router to allow a software application running on any computer on your network to connect to a web-based server or another user on the Internet.
Firewall Port Enter the port range that you want to open up to Internet traffic (for example 6000-6200). Firewall Traffic Type Select the protocol used by the Internet traffic coming back into the router through the opened port range (for example Both). Schedule Select a schedule for when this rule is in effect. If you do not see the schedule you need in the list of schedules, go to the Tools → Schedules screen and create a new schedule.
Advanced_ Port Forwarding Multiple connections are required by some applications, such as internet games, video conferencing, Internet telephony, and others. These applications have difficulties working through NAT (Network Address Translation). This section is used to open multiple ports or a range of ports in your router and redirect data through those ports to a single PC on your network.
in accordingly. However, you should check whether the port values have changed since this list was created, and you must fill in the IP address field. IP Address Enter the local network IP address of the system hosting the server, for example 192.168.0.50. You can select a computer from the list of DHCP clients in the "Computer Name" drop-down menu, or you can manually enter the IP address of the server computer. TCP Ports Enter the TCP ports to open (for example 6159-6180, 99).
The StreamEngine feature helps improve your network performance by prioritizing applications. WAN Traffic Shaping Enable Traffic Shaping When this option is enabled, the router restricts the flow of outbound traffic so as not to exceed the WAN uplink bandwidth. Automatic Uplink Speed When enabled, this option causes the router to automatically measure the useful uplink bandwidth each time the WAN interface is re-established (after a reboot, for example).
network connections. Manual Uplink Speed If Automatic Uplink Speed is disabled, this options allows you to set the uplink speed manually. Uplink speed is the speed at which data can be transferred from the router to your ISP. This is determined by your ISP. ISPs often specify speed as a downlink/uplink pair; for example, 1.5Mbps/284kbps. For this example, you would enter "284". Alternatively you can test your uplink speed with a service such as www.dslreports.com.
Priority The priority of the message flow is entered here -- 0 receives the highest priority (most urgent) and 255 receives the lowest priority (least urgent). Protocol The protocol used by the messages. Local IP Range The rule applies to a flow of messages whose LAN-side IP address falls within the range set here. Local Port Range The rule applies to a flow of messages whose LAN-side port number is within the range set here.
Add/Edit Route Adds a new route to the IP routing table or edits an existing route. Enable Specifies whether the entry will be enabled or disabled. Destination IP The IP address of packets that will take this route. Netmask One bits in the mask specify which bits of the IP address must match. Gateway Specifies the next hop to be taken if this route is used. A gateway of 0.0.0.
Routes List The section shows the current routing table entries. Certain required routes are predefined and cannot be changed. Routes that you add can be changed by clicking the Edit icon or can be deleted by clicking the Delete icon. When you click the Edit icon, the item is highlighted, and the "Edit Route" section is activated for editing. Click the Enable checkbox at the left to directly activate or de-activate the entry.
Advanced_Access Control The Access Control section allows you to control access in and out of devices on your network. Use this feature as Parental Controls to only grant access to approved sites, limit web access based on time or dates, and/or block access from applications such as peer-to-peer utilities or games. Enable By default, the Access Control feature is disabled. If you need Access Control, check this option.
Advanced_WEB Filter The Web sites listed here are used when the Web Filter option is enabled in Advanced → Access Control. Add Web Filtering Rule This section is where you add the Web sites to be used for Access Control. Website URL/Domain google.com. http:// preceding the URL. Enter the most inclusive domain; for example, enter ubicom.com and access will be permitted to both www.ubicom.com and support.ubicom.com.
Advanced_ MAC Address Filter (Network Filter) The MAC address filter section can be used to filter network access by machines based on the unique MAC addresses of their network adapter(s). It is most useful to prevent unauthorized wireless devices from connecting to your network. A MAC address is a unique ID assigned by the manufacturer of the network adapter. MAC Filtering Setup Choose the type of MAC filtering needed.
Advanced_ Firewall Settings The router provides a tight firewall by virtue of the way NAT works. Unless you configure the router to the contrary, the NAT does not respond to unsolicited incoming requests on any port, thereby making your LAN invisible to Internet cyberattackers. However, some network applications cannot run with a tight firewall. Those applications need to selectively open ports in the firewall to function correctly.
Firewall Settings Enable SPI SPI ("stateful packet inspection" also known as "dynamic packet filtering") helps to prevent cyberattacks by tracking more state per session. It validates that the traffic passing through that session conforms to the protocol. When the protocol is TCP, SPI checks that packet sequence numbers are within the valid range for the session, discarding those packets that do not have valid sequence numbers.
TCP Endpoint Filtering Controls endpoint filtering for packets of the TCP protocol. Formerly, the terms "Full Cone", "Restricted Cone", "Port Restricted Cone" and "Symmetric" were used to refer to different variations of NATs. These terms are purposely not used here, because they do not fully describe the behavior of this router's NAT.
• A host needs to support several applications that might use overlapping ingress ports such that two port forwarding rules cannot be used because they would potentially be in conflict. • To handle incoming connections that use a protocol other than ICMP, TCP, UDP, and IGMP (also GRE and ESP, when these protocols are enabled by the PPTP and IPSec ALGs ). Enable DMZ Note: Putting a computer in the DMZ may expose that computer to a variety of security risks.
multiple VPN pass-through in this case, the IPSec ALG must be enabled. RTSP Allows applications that use Real Time Streaming Protocol to receive streaming media from the internet. QuickTime and Real Player are some of the common applications using this protocol. Windows/MSN Messenger Supports use on LAN computers of Microsoft Windows Messenger (the Internet messaging client that ships with Microsoft Windows) and MSN Messenger. The SIP ALG must also be enabled when the Windows Messenger ALG is enabled.
Advanced_ Inbound Filter When you use the Virtual Server, Port Forwarding, or Remote Administration features to open specific ports to traffic from the Internet, you could be increasing the exposure of your LAN to cyberattacks from the Internet. In these cases, you can use Inbound Filters to limit that exposure by specifying the IP addresses of internet hosts that you trust to access your LAN through the ports that you have opened.
Enter a name for the rule that is meaningful to you. Action The rule can either Allow or Deny messages. Remote IP Range Define the ranges of Internet addresses this rule applies to. For a single IP address, enter the same address in both the Start and End boxes. Up to eight ranges can be entered. The Enable checkbox allows you to turn on or off specific entries in the list of ranges. Save/Update Record the changes you have made into the following list.
Advanced_ Advanced Wireless Transmit Power Normally the wireless transmitter operates at 100% power. In some circumstances, however, there might be a need to isolate specific frequencies to a smaller area. By reducing the power of the radio, you can prevent transmissions from reaching beyond your corporate/home office or designated wireless area. Beacon Period Beacons are packets sent by a wireless router to synchronize wireless devices. Specify a Beacon Period value between 20 and 1000.
beacons and awaken to receive the broadcast and multicast messages. The default value is 1. Valid settings are between 1 and 255. Wireless Isolation Enabling Wireless Isolation prevents associated wireless clients from communicating with each other. WMM Enable Enabling WMM can help control latency and jitter when transmitting multimedia content over a wireless connection. Short GI Using a short (400ns) guard interval can increase throughput.
Advanced_ WISH WISH is short for Wireless Intelligent Stream Handling, a technology developed to enhance your experience of using a wireless network by prioritizing the traffic of different applications. WISH Enable WISH Enable this option if you want to allow WISH to prioritize your traffic. Priority Classifiers HTTP Allows the router to recognize HTTP transfers for many common audio and video streams and prioritize them above other traffic. Such streams are frequently used by digital media players.
Automatic When enabled, this option causes the router to automatically attempt to prioritize traffic streams that it doesn't otherwise recognize, based on the behaviour that the streams exhibit. This acts to deprioritize streams that exhibit bulk transfer characteristics, such as file transfers, while leaving interactive traffic, such as gaming or VoIP, running at a normal priority. Add/Edit WISH Rule A WISH Rule identifies a specific message flow and assigns a priority to that flow.
WISH Rules This section lists the defined WISH Rules. Click the Enable checkbox at the left to directly activate or de-activate the entry. An entry can be changed by clicking the Edit icon or can be deleted by clicking the Delete icon. When you click the Edit icon, the item is highlighted, and the "Edit WISH Rule" section is activated for editing.
Advanced_ Wi-Fi Protected Setup Wi-Fi Protected Setup Enable Enable the Wi-Fi Protected Setup feature. Lock Wireless Security Settings Locking the wireless security settings prevents the settings from being changed by any new external registrar using its PIN. Devices can still be added to the wireless network using Wi-Fi Protected Setup. It is still possible to change wireless network settings with Manual Wireless Network Setup, Wireless Network Setup Wizard, or an existing external WLAN Manager Registrar.
Add Wireless Station This Wizard helps you add wireless devices to the wireless network. The wizard will either display the wireless network settings to guide you through manual configuration, prompt you to enter the PIN for the device, or ask you to press the configuration button on the device. If the device supports Wi-Fi Protected Setup and has a configuration button, you can add it to the network by pressing the configuration button on the device and then the on the router within 60 seconds.
Advanced_ Advanced Network UPnP UPnP is short for Universal Plug and Play, which is a networking architecture that provides compatibility among networking equipment, software, and peripherals. This router has optional UPnP capability, and can work with other UPnP devices and software. Enable UPnP If you need to use the UPnP functionality, you can enable it here. Allow Users to disable Internet Access Disabling this option prevents UPnP clients from terminating the WAN connection.
your WAN IP address is valid. Enable WAN Ping Respond If you leave this option unchecked, you are causing the router to ignore the public WAN IP address of the router. ping commands for WAN Ping Inbound Filter Select a filter that controls which WAN computers can use the ping feature.
