Encryption Off • If OFF (default), data is NOT encrypted before being transmitted. 64 Bit Encryption • If selected, data is encrypted, using the default key, before being transmitted. The receiving station must be set to use 64 Bit En-cryption, and have the same Key value in the same position in its key table. Otherwise, it will not be able to decrypt the data. • Default Key - select the key you wish to be the default. Transmit-ted data is ALWAYS encrypted using the Default Key; the other Keys are for decryption only. • Key Table: • This table is used when Encrypting and Decrypting data. All stations, including this Access Point, always transmit data en-crypted using their default key. The key number (1, 2, 3, 4) is also transmitted. The receiving station will use the key num-ber (1, 2, 3, 4) to determine which key value to use for decryption. If the key value does not match the transmitting station, decryption will fail. • The easiest way to ensure there are no problems is to have every Station, including the Access Point, use the same key table (all entries identical). 18
Setup 128 Bit Encryption • If selected, data is encrypted using the key before being transmit-ted. The receiving station must be set to use 128 Bit Encryption, and have the same Key value. Otherwise, it will not be able to de-crypt the data. • Key - Enter the key value you wish to use. Other stations must have the same key. 19

LevelOne 22Mbps Wireless AP Router User Guide Special Applications If you use Internet applications which use non-standard connections or port numbers, you may find that they do not function correctly because they are blocked by the LevelOne 22Mbps Wireless AP Router 's firewall. In this case, you can define the application as a "Special Application". Special Applications Screen This screen can be reached by clicking the Special Applications button on the Internet screen. You can then define your Special Applications. You will need detailed information about the application; this is normally available from the supplier of the application. Also, note that the terms "Incoming" and "Outgoing" on this screen refer to traffic from the client (PC) viewpoint Figure 28: Special Applications Screen 44
Advanced Features Data - Special Applications Screen Checkbox Use this to Enable or Disable this Special Application as required. Name Enter a descriptive name to identify this Special Application. Incoming Ports • Type - Select the protocol (TCP or UDP) used when you receive data from the special application or service. (Note: Some applications use different protocols for outgoing and incoming data). • Start - Enter the beginning of the range of port numbers used by the application server, for data you receive. If the application uses a single port number, enter it in both the "Start" and "Finish" fields. • Finish - Enter the end of the range of port numbers used by the applica-tion server, for data you receive. Outgoing Ports • Type - Select the protocol (TCP or UDP) used when you send data to the remote system or service. • Start - Enter the beginning of the range of port numbers used by the application server, for data you send to it. If the application uses a sin-gle port number, enter it in both the "Start" and "Finish" fields. • Finish - Enter the end of the range of port numbers used by the applica-tion server, for data you send to it. If the application uses a single port number, enter it in both the "Start" and "Finish" fields. Using a Special Application • Configure the Special Applications screen as required. • On your PC, use the application normally. Remember that only one (1) PC can use each Special application at any time. Also, when 1 PC is finished using a particular Special Ap-plication, there may need to be a "Time-out" before another PC can use the same Special Application. The "Time-out" period may be up to 3 minutes. If an application still cannot function correctly, try using the "DMZ" feature. 45
LevelOne 22Mbps Wireless AP Router User Guide DMZ This feature, if enabled, allows one (1) computer on your LAN to be exposed to all users on the Internet, allowing unrestricted 2-way communication between the "DMZ PC" and other Internet users or Servers. • This allows almost any application to be used on the "DMZ PC". • The "DMZ PC" will receive all "Unknown" connections and data. • If the DMZ feature is enabled, you must select the PC to be used as the "DMZ PC". • The DMZ feature can be Enabled and Disabled on the Advanced Internet screen. The "DMZ PC" is effectively outside the Firewall, mak-ing it more vulnerable to attacks. For this reason, you should only enable the DMZ feature when required. URL Filter The URL Filter allows you to block access to undesirable Web site • To use this feature, you must define "filter strings". If the "filter string" appears in a requested URL, the request is blocked. • Enabling the URL Filter also affects the Internet Access Log. If Enabled, the "Destination" field in the log will display the URL. Otherwise, it will display the IP Address. • The URL Filter can be Enabled or Disabled on the Advanced Internet screen.

LevelOne 22Mbps Wireless AP Router User Guide Remote Management This feature allows you to manage the LevelOne 22Mbps Wireless AP Router via the Internet. Figure 30: Remote Management Screen Data - Remote Management Screen Remote Management Enable Remote Management Enable to allow management via the Internet. If Disabled, this device will ignore management connection attempts from the Internet. Port Number Enter a port number between 1024 and 65535 (8080 is recom-mended). This port number must be specified when you connect (see below). Note: The default port number for HTTP (Web) connections is port 80, but using port 80 here will prevent the use of a Web "Virtual Server" on your LAN. (See Advanced Internet - Virtual Servers) Current IP Ad-dress You must use this IP Address to connect (see below). This IP Address is allocated by your ISP. But if using a Dynamic IP Address, this value can change each time you connect to your ISP. So it is better if your ISP allocates you a Fixed IP Address. To connect from a remote PC via the Internet 1. Ensure your Internet connection is established, and start your Web Browser. 2. In the "Address" bar, enter "HTTP://" followed by the Internet IP Address of the Leve-lOne 22Mbps Wireless AP Router. If the port number is not 80, the port number is also required. (After the IP Address, enter ":" followed by the port number.) e.g. HTTP://123.123.123.123:8080 This example assumes the WAN IP Address is 123.123.123.123, and the port number is 8080. 48
Advanced Features Virtual Servers This feature allows you to make Servers on your LAN accessible to Internet users. Normally, Internet users would not be able to access a server on your LAN because: • Your Server does not have a valid external IP Address. • Attempts to connect to devices on your LAN are blocked by the firewall in this device. The "Virtual Server" feature solves these problems and allows Internet users to connect to your servers, as illustrated below. WirelessRouterWeb Se rve r FTP Serv erInternetRemote PC Remote PCUsing Web Server Using FTP Server(http://203.70.212.52) (ftp://203.70.212.52)203.70.212.52192.168.0.1(192.168.0.10) (192.168 .0.20)(LAN IP Ad dres s)(Internet IP Address) Figure 31: Virtual Servers IP Address seen by Internet Users Note that, in this illustration, both Internet users are connecting to the same IP Address, but using different protocols. To Internet users, all virtual Servers on your LAN have the same IP Address. This IP Address is allocated by your ISP. This address should be static, rather than dynamic, to make it easier for Internet users to connect to your Servers. However, you can use the DDNS (Dynamic DNS) feature to allow users to connect to your Virtual Servers using a URL, instead of an IP Address. 49
LevelOne 22Mbps Wireless AP Router User Guide Virtual Servers Screen The Virtual Servers screen is reached by the Virtual Servers link on the Advanced screen. An example screen is shown below. Figure 32: Virtual Servers Screen This screen lists a number of pre-defined Servers, and allows you to define your own Servers. Details of the selected Server are shown in the "Properties" area. Data - Virtual Servers Screen Servers Servers This lists a number of pre-defined Servers, plus any Servers you have defined. Details of the selected Server are shown in the "Properties" area. Properties Enable Use this to Enable or Disable support for this Server, as required. • If Enabled, any incoming connections will be forwarded to the selected PC. • If Disabled, any incoming connection attempts will be blocked. PC (Server) Select the PC for this Server. The PC must be running the appro-priate Server software. Protocol Select the protocol (TCP or UDP) used by the Server. Internal Port No. Enter the port number which the Server software is configured to use. External Port No. The port number used by Internet users when connecting to the Server. This is normally the same as the Internal Port Number. If it is different, this device will perform a "mapping" or "translation" function, allowing the server to use one port address, while clients use a different port address. 50
Advanced Features Buttons Defaults This will delete any Servers you have defined, and set the pre-defined Servers to use their default port numbers. Disable All This will cause the "Enable" setting of all Virtual Servers to be set OFF. Add Add a new entry to the Virtual Server list, using the data shown in the "Properties" area on screen. The entry selected in the list is ignored, and has no effect. Update Update the current Virtual Server entry, using the data shown in the "Properties" area on screen. Delete Delete the current Virtual Server entry. Note that the pre-defined Servers can not be deleted. Only Servers you have defined yourself can be deleted. Clear Form Clear all data from the "Properties" area, ready for input of a new Virtual Server entry. For each entry, the PC must be running the appropriate Server software. Defining your own Virtual Servers If the type of Server you wish to use is not listed on the Virtual Servers screen, you can define and manage your own Servers: Create a new Server: 1. Click "Clear Form" 2. Enter the required data, as described above. 3. Click "Add". 4. The new Server will now appear in the list. Modify (Edit) a Server: 5. Select the desired Server from the list 6. Make any desired changes (for example, change the Enable/Disable setting). 7. Click "Update" to save changes to the selected Server. Delete a Server: 8. Select the entry from the list. 9. Click "Delete". Note: You can only delete Servers you have defined. Pre-defined Server cannot be deleted. From the Internet, ALL Virtual Servers have the IP Address allocated by your ISP. 51
LevelOne 22Mbps Wireless AP Router User Guide Connecting to the Virtual Servers Once configured, anyone on the Internet can connect to your Virtual Servers. They must use the Internet IP Address (the IP Address allocated to you by your ISP). e.g. http://203.70.212.52 ftp://203.70.212.52 It is more convenient if you are using a Fixed IP Address from your ISP, rather than Dynamic. However, you can use the Dynamic DNS feature, described in the following section, to allow users to connect to your Virtual Servers using a URL, rather than an IP Address. Dynamic DNS (Domain Name Server) This free service is very useful when combined with the Virtual Server feature. It allows Internet users to connect to your Virtual Servers using a URL, rather than an IP Address. This also solves the problem of having a dynamic IP address. With a dynamic IP address, your IP address may change whenever you connect, which makes it difficult to connect to you. The Service works as follows: 1. You must register for the service at http://www.dyndns.org (Registration is free). Your password will be E-mailed to you. 2. After registration, use the "Create New Host" option (at www.dyndns.org) to request your desired Domain name. 3. Enter your data from www.dyndns.org in the LevelOne 22Mbps Wireless AP Router's DDNS screen. 4. The LevelOne 22Mbps Wireless AP Router will then automatically ensure that your current IP Address is recorded at http://www.dyndns.org 5. From the Internet, users will be able to connect to your Virtual Servers (or DMZ PC) using your Domain name, as shown on this screen. 52
Advanced Features Dynamic DNS Screen Select Advanced on the main menu, then Dynamic DNS, to see a screen like the following: Figure 33: DDNS Screen Data - Dynamic DNS Screen DDNS Service DDNS Service • You must sign up first to create a new account before using the service. The service is free. • Click this link to connect to the www.dyndns.org Web site. • Your initial password will be E-mailed to you; you can change this later if you wish. • After registration, use the "Create New Host" link (on the www.dyndns.org Web site) to request a domain name. DDNS Data User Name Enter the "User name" specified at the www.dyndns.org Web site when you registered. Password Enter your current password for www.dyndns.org Domain • Enter your domain name, as allocated at www.dyndns.org. • The name should consist only of letters and the hyphen (dash). Using any other characters may cause problems.. DDNS Status This message is returned by the DDNS Server at www.dyndns.org • Normally, this message should be "Update successful" (current IP address was updated on the www.dyndns.org server). • If the message is "No host", this indicates the host name entered was not allocated to you. You need to connect to www.dyndns.org and correct this problem. 53
Chapter 7 Advanced Configuration This Chapter explains the settings available via the Advanced configuration section of the "Advanced" menu. Overview Normally, it is not necessary to use these screens, or change any settings. These screens and settings are provided to deal with non-standard situations, or to provide additional options for advanced users. The settings available are: PC Database This is the list of PCs shown when you select the "DMZ PC" or a "Vir-tual Server". This database is maintained automatically, but you can add and delete entries for PCs which use a Fixed (Static) IP Address. Options Various options, such as backup DNS, UPnP, and enable TFTP firm-ware upgrade option. MAC Address Set the MAC (hardware) address used on the Internet (WAN port) interface. This is required only if your ISP has recorded the MAC (hardware) address you should use. Routing Only required if your LAN has other Routers or Gateways. 54
Advanced Configuration PC Database The PC Database is used whenever you need to select a PC (e.g. for the "DMZ" PC). It elimi-nates the need to enter IP addresses. Also, you do not need to use fixed IP addresses on your LAN. PC Database Screen An example PC Database screen is shown below. Figure 34: PC Database • PCs which are "DHCP Clients" are automatically added to the database, and updated as required. • By default, non-Server versions of Windows act as "DHCP Clients"; this setting is called "Obtain an IP Address automatically". • The LevelOne 22Mbps Wireless AP Router uses the "Hardware Address" to identify each PC, not the name or IP address. The "Hardware Address" can only change if you change the PC's network card or adapter. • This system means you do NOT need to use Fixed (static) IP addresses on your LAN. However, you can add PCs using Fixed (static) IP Addresses to the PC database if re-quired. Data - PC Database Screen PC Database PCs This lists all current entries. Data displayed is name (IP Address) type. The "type" indicates whether the PC is connected to the LAN or WLAN (Wireless LAN). Name If adding a new PC to the list, enter its name here. It is best if this matches the PC's "hostname". IP Address Enter the IP Address of the PC. The PC will be sent a "ping" to deter-mine its hardware address. If the PC is not available (not connected, or not powered On) you will not be able to add it. 55

Advanced Configuration Options This screen allows advanced users to enter or change a number of settings. For normal opera-tion, there is no need to use this screen or change any settings. An example Options screen is shown below. Figure 35: Options Screen Data - Options Screen Backup DNS IP Address Enter the IP Address of the DNS (Domain Name Servers) here. These DNS will be used only if the primary DNS is unavailable. TFTP Enable Firm-ware Upgrade using TFTP • If enabled, TFTP (Trivial FTP) can be used to upgrade the firm-ware in this device. This is normally not required; a Windows utility is available for this purpose. • You must obtain the firmware upgrade file first; instructions for using TFTP will be available with the upgrade. UPnP Enable UPnP Services • UPnP (Universal Plug and Play) allows automatic discovery and configuration of equipment attached to your LAN. UPnP is by supported by Windows ME, XP, or later. • If Enabled, this device will be visible via UPnP. • If Disabled, this device will not be visible via UPnP. Allow Configu-ration... • If checked, then UPnP users can change the configuration. • If Disabled, UPnP users can only view the configuration. But currently, this restriction only applies to users running Windows XP, who access the Properties via UPnP. (e.g. Right - click the LevelOne 22Mbps Wireless AP Router in My Network Places, and select Properties) 57
LevelOne 22Mbps Wireless AP Router User Guide Allow Internet access to be disabled • If checked, then UPnP users can disable Internet access via this device. • If Disabled, UPnP users can NOT disable Internet access via this device. But currently, this restriction only applies to users running Windows XP, who access the Properties via UPnP. (e.g. Right - click the LevelOne 22Mbps Wireless AP Router in My Network Places, and select Properties) Firewall Enable DoS Firewall If enabled, DoS (Denial of Service) attacks will be detected and blocked. The default is enabled. It is strongly recommended that this setting be left enabled. Note: • A DoS attack does not attempt to steal data or damage your PCs, but overloads your Internet connection so you cannot use it - the service is unavailable. • The LevelOne 22Mbps Wireless AP Router uses "Stateful Inspec-tion" technology. This system can detect situations where individual TCP/IP packets are valid, but collectively they become a DoS attack. Threshold This setting affects the number of "half-open" connections allowed. • A "half-open" connection arises when a remote client contacts the Server with a connection request, but then does not reply to the Server's response. • While the optimum number of "half-open" connections allowed (the "Threshold") depends on many factors, the most important factor is the available bandwidth of your Internet connection. • Select the setting to match the bandwidth of your Internet connec-tion. 58
Advanced Configuration MAC Address The MAC (hardware) address is a low-level network identifier. It may be called "MAC Ad-dress", "Hardware Address", or "Physical Address". On a PC, this address is associated with the Network card or adapter. The address on the MAC Address screen is the address on the Internet (WAN port) interface, and has no effect on the LAN interface. • If your ISP asks for the "Network Adapter Address", "Physical Address", "Hardware Address", or "MAC Address" for the PC the DSL/Cable modem is connected to, provide this value. • If your ISP has already recorded a MAC address, you can change the address used by the LevelOne 22Mbps Wireless AP Router to match the address recorded by your ISP. MAC Address Screen Select MAC Address from the Advanced menu to reach a screen like the example below. Figure 36: MAC address Screen Data - MAC address Screen MAC (hardware) Address The current MAC (hardware) address is displayed. If your ISP has recorded a Hardware Address, you can "spoof" that address by entering it in the address field. The hardware address consists of 12 characters, where each character is a digit (0..9) or a character between A and F. Buttons Default Inserts the default MAC address into the MAC address field. You must click "Save" to actually change the address used. Copy from PC Inserts the MAC address from your PC into the MAC address field. You must click "Save" to actually change the address used. Save Save your changes to the LevelOne 22Mbps Wireless AP Router. Cancel Reverse any changes made since the last "Save". 59
LevelOne 22Mbps Wireless AP Router User Guide If the MAC address is changed, the LevelOne 22Mbps Wireless AP Router must restart. Routing Overview • If you don't have other Routers or Gateways on your LAN, you can ignore the "Routing" page completely. • If the LevelOne 22Mbps Wireless AP Router is only acting as a Gateway for the local LAN segment, ignore the "Routing" page even if your LAN has other Routers. • If your LAN has a standard Router (e.g. Cisco) on your LAN, and the LevelOne 22Mbps Wireless AP Router is to act as a Gateway for all LAN segments, enable RIP (Routing In-formation Protocol) and ignore the Static Routing table. • If your LAN has other Gateways and Routers, and you wish to control which LAN seg-ments use each Gateway, do NOT enable RIP (Routing Information Protocol). Configure the Static Routing table instead. (You also need to configure the other Routers.) • If using Windows 2000 Data center Server as a software Router, enable RIP on the Leve-lOne 22Mbps Wireless AP Router, and ensure the following Windows 2000 settings are correct: • Open Routing and Remote Access • In the console tree, select Routing and Remote Access , [server name], IP Routing, RIP • In the "Details" pane, right-click the interface you want to configure for RIP version 2, and then click "Properties". • On the "General" tab, set Outgoing packet protocol to "RIP version 2 broadcast", and Incoming packet protocol to "RIP version 1 and 2". Routing Screen The routing table is accessed by the Routing link on the Advanced screen. Using this Screen Generally, you will use either RIP (Routing Information Protocol) OR the Static Routing Table, as explained above, although is it possible to use both methods simultaneously. Static Routing Table • If RIP is not used, an entry in the routing table is required for each LAN segment on your Network, other than the segment to which this device is attached. • The other Routers must also be configured. See Configuring Other Routers on your LAN later in this chapter for further details and an example. 60

The LevelOne 22Mbps Wireless AP Router supports RIP 1 only. Static Routing Static Routing Table Entries This list shows all entries in the Routing Table. • The "Properties" area shows details of the selected item in the list. • Change any the properties as required, then click the "Update" button to save the changes to the selected entry. Properties • Destination Network - The network address of the remote LAN segment. For standard class "C" LANs, the network address is the first 3 fields of the Destination IP Address. The 4th (last) field can be left at 0. • Network Mask - The Network Mask for the remote LAN segment. For class "C" networks, the default mask is 255.255.255.0 • Gateway IP Address - The IP Address of the Gateway or Router which the LevelOne 22Mbps Wireless AP Router must use to communicate with the destination above. (NOT the router attached to the remote segment.) • Metric - The number of "hops" (routers) to pass through to reach the remote LAN segment. The shortest path will be used. The default value is 1. Buttons Save Save the RIP setting. This has no effect on the Static Routing Table. 61

The entry selected in the list is ignored, and has no effect. Update Update the current Static Routing Table entry, using the data shown in the "Properties" area on screen. Delete Delete the current Static Routing Table entry. Clear Form Clear all data from the "Properties" area, ready for input of a new entry for the Static Routing table. Generate Report Generate a read-only list of all entries in the Static Routing table. Configuring Other Routers on your LAN It is essential that all IP packets for devices not on the local LAN be passed to the LevelOne 22Mbps Wireless AP Router, so that they can be forwarded to the external LAN, WAN, or Internet. To achieve this, the local LAN must be configured to use the LevelOne 22Mbps Wireless AP Router as the Default Route or Default Gateway. Local Router The local router is the Router installed on the same LAN segment as the LevelOne 22Mbps Wireless AP Router. This router requires that the Default Route is the LevelOne 22Mbps Wireless AP Router itself. Typically, routers have a special entry for the Default Route. It should be configured as follows. Destination IP Address Normally 0.0.0.0, but check your router documentation. Network Mask Normally 0.0.0.0, but check your router documentation. Gateway IP Address The IP Address of the LevelOne 22Mbps Wireless AP Router. Metric 1 Other Routers on the Local LAN Other routers on the local LAN must use the LevelOne 22Mbps Wireless AP Router's Local Router as the Default Route. The entries will be the same as the LevelOne 22Mbps Wireless AP Router's local router, with the exception of the Gateway IP Address. • For a router with a direct connection to the LevelOne 22Mbps Wireless AP Router's local Router, the Gateway IP Address is the address of the LevelOne 22Mbps Wireless AP Router's local router. • For routers which must forward packets to another router before reaching the LevelOne 22Mbps Wireless AP Router's local router, the Gateway IP Address is the address of the intermediate router. 62

64 A Appendix A Troubleshooting This Appendix covers the most likely problems and their solutions. Overview This chapter covers some common problems that may be encountered while using the Leve-lOne 22Mbps Wireless AP Router and some possible solutions to them. If you follow the suggested steps and the LevelOne 22Mbps Wireless AP Router still does not function prop-erly, contact your dealer for further advice. General Problems Problem 1: Can't connect to the LevelOne 22Mbps Wireless AP Router to config-ure it. Solution 1: Check the following: • The LevelOne 22Mbps Wireless AP Router is properly installed, LAN connections are OK, and it is powered ON. • Ensure that your PC and the LevelOne 22Mbps Wireless AP Router are on the same network segment. (If you don't have a router, this must be the case.) • If your PC is set to "Obtain an IP Address automatically" (DHCP client), restart it. • If your PC uses a Fixed (Static) IP address, ensure that it is using an IP Address within the range 192.168.0.2 to 192.168.0.254 and thus com-patible with the LevelOne 22Mbps Wireless AP Router's default IP Address of 192.168.0.1. Also, the Network Mask should be set to 255.255.255.0 to match the LevelOne 22Mbps Wireless AP Router. In Windows, you can check these settings by using Control Panel-Network to check the Properties for the TCP/IP protocol. Internet Access Problem 1: When I enter a URL or IP address I get a time out error. Solution 1: A number of things could be causing this. Try the following troubleshooting steps. • Check if other PCs work. If they do, ensure that your PCs IP settings are correct. If using a Fixed (Static) IP Address, check the Network Mask, Default gateway and DNS as well as the IP Address. • If the PCs are configured correctly, but still not working, check the LevelOne 22Mbps Wireless AP Router. Ensure that it is connected and ON. Connect to it and check its settings. (If you can't connect to it, check the LAN and power connections.) • If the LevelOne 22Mbps Wireless AP Router is configured correctly,
Appendix A - Troubleshooting check your Internet connection (DSL/Cable modem etc) to see that it is working correctly. Problem 2: Some applications do not run properly when using the LevelOne 22Mbps Wireless AP Router. Solution 2: The LevelOne 22Mbps Wireless AP Router processes the data passing through it, so it is not transparent. Use the Special Applications feature to allow the use of Internet applications which do not function correctly. If this does solve the problem you can use the DMZ function. This should work with almost every application, but: • It is a security risk, since the firewall is disabled. • Only one (1) PC can use this feature. Wireless Access Problem 1: My PC can't locate the Wireless Access Point. Solution 1: Check the following. • Your PC is set to Infrastructure Mode. (Access Points are always in Infrastructure Mode) • The SSID on your PC and the Wireless Access Point are the same. Remember that the SSID is case-sensitive. So, for example "Work-group" does NOT match "workgroup". • Both your PC and the Wireless Access Point must have the same setting for WEP. The default setting for the LevelOne 22Mbps Wireless AP Router is disabled, so your wireless station should also have WEP dis-abled. • If WEP is enabled on the LevelOne 22Mbps Wireless AP Router, your PC must have WEP enabled, and the key tables (for 64 Bit encryption) or key (for 128 Bit encryption) must match. • If the LevelOne 22Mbps Wireless AP Router's Wireless screen is set to Allow LAN access to selected Wireless Stations only, then each of your Wireless stations must have been selected, or access will be blocked. • To see if radio interference is causing a problem, see if connection is possible when close to the Wireless Access Point. Remember that the connection range can be as little as 100 feet in poor environments. Problem 2: Wireless connection speed is very slow. Solution 2: The wireless system will connect at the highest possible speed, depending on the distance and the environment. To obtain the highest possible connec-tion speed, you can experiment with the following: • Access Point location. Try adjusting the location and orientation of the Access Point. • Wireless Channel If interference is the problem, changing to another channel may show a marked improvement. • Radio Interference Other devices may be causing interference. You can experiment by 65
LevelOne 22Mbps Wireless AP Router User Guide switching other devices Off, and see if this helps. Any "noisy" devices should be shielded or relocated. • RF Shielding Your environment may tend to block transmission between the wireless stations. This will mean high access speed is only possible when close to the Access Point. 66
67 B Appendix B About Wireless LANs This Appendix provides some background information about using Wireless LANs (WLANs). Modes Wireless LANs can work in either of two (2) modes: • Ad-hoc • Infrastructure Ad-hoc Mode Ad-hoc mode does not require an Access Point or a wired (Ethernet) LAN. Wireless Sta-tions (e.g. notebook PCs with wireless cards) communicate directly with each other. Infrastructure Mode In Infrastructure Mode, one or more Access Points are used to connect Wireless Stations (e.g. Notebook PCs with wireless cards) to a wired (Ethernet) LAN. The Wireless Stations can then access all LAN resources. Access Points can only function in "Infrastructure" mode, and can communicate only with Wireless Stations which are set to "Infrastructure" mode. BSS/ESS BSS A group of Wireless Stations and a single Access Point, all using the same ID (SSID), form a Basic Service Set (BSS). Using the same SSID is essential. Devices with different SSIDs are unable to communicate with each other. ESS A group of Wireless Stations, and multiple Access Points, all using the same ID (ESSID), form an Extended Service Set (ESS). Different Access Points within an ESS can use different Channels. In fact, to reduce interfer-ence, it is recommended that adjacent Access Points SHOULD use different channels. As Wireless Stations are physically moved through the area covered by an ESS, they will automatically change to the Access Point which has the least interference or best performance. This capability is called Roaming. (Access Points do not have or require Roaming capabili-ties.)
LevelOne 22Mbps Wireless AP Router User Guide Channels The Wireless Channel sets the radio frequency used for communication. • Access Points use a fixed Channel. You can select the Channel used. This allows you to choose a Channel which provides the least interference and best performance. In the USA and Canada, 11 channel are available. If using multiple Access Points, it is better if adja-cent Access Points use different Channels to reduce interference. • In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for an Access Point. If more than one Access Point can be used, the one with the strongest signal is used. (This can only happen within an ESS.) • If using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to use the same Channel. However, most Wireless stations will still scan all Channels to see if there is an existing "Ad-hoc" group they can join. WEP WEP (Wired Equivalent Privacy) is a standard for encrypting data before it is transmitted. This is desirable because it is impossible to prevent snoopers from receiving any data which is transmitted by your Wireless Stations. But if the data is encrypted, then it is meaningless unless the receiver can decrypt it. If WEP is used, the Wireless Stations and the Access Point must have the same settings for each of the following: WEP Off, 64 Bit, 128 Bit Key For 64 Bit encryption, the Key Table must match. For 128 Bit encryption, the Key value must match. WEP Authentication Open System or Shared Key. Wireless LAN Configuration To allow Wireless Stations to use the Access Point, the Wireless Stations and the Access Point must use the same settings, as follows: Mode On client Wireless Stations, the mode must be set to "Infrastructure". (The Access Point is always in "Infrastructure" mode.) SSID (ESSID) Wireless Stations should use the same SSID (ESSID) as the Access Point they wish to connect to. Alternatively, the SSID can be set to "any" or null (blank) to allow connection to any Access Point. WEP The Wireless Stations and the Access Point must use the same settings for WEP (Off, 64 Bit, or 128 Bit). WEP Key: If WEP is enabled, the Key Table (for 64 Bit encryption) or Key (for 128 Bit Encryption) must be the same on the Wireless Stations and the Access Point. WEP Authentication: If WEP is enabled, all Wireless Stations must use the same setting as the Access Point (either "Open System" or "Shared Key"). 68
