When deploying a metropolitan Wi-Fi solution, in many cases the signal is not sufficiently strong enough to penetrate residential buildings and establish a reliable connection with low-end consumer wireless network interfaces. The EWS-150g overcomes this problem by providing a higher transmit power with high gain antennas, ensuring that your wireless customers stay connected. The EWS-150g also offers a suite of management features—including a powerful Web Management Interface (WMI) and SNMP—that have been tailored for residential users, including the ability to upgrade the EWS-150g firmware remotely, performance monitoring, and usage history logs. Bridging the Network The EWS-150g bridges connectivity between a Wireless Wide Area Network (WWAN), consisting of multiple Strix Outdoor Wireless System (OWS) nodes formed as a structured mesh, an indoor wired Local Area Network (LAN), and/or an indoor Wireless Local Area Network (WLAN). This bridging function is provided with Layer 2 Network Address Translation (NAT) so that multiple computers can be supported by a single association between the OWS and the EWS-150g, while still receiving IP address assignments from the WISP gateway via DHCP. Figure 1 shows a generalized application for the EWS-150g. Figure 1. Bridging the Network EWS-150g Configuration Guide EWS-150g Configuration Guide 802.11g Wireless Technology The EWS-150g is an 802.11g radio device with the 802.11g radio acting as a Wireless Client Station. Figure 2 shows the rear of the EWS-150g unit, highlighting the antennas, the Ethernet LAN port, the DC power receptacle and the reset button. Antenna DC power Ethernet port Reset button Figure 2. EWS-150g (Rear View) EWS-150g Configuration Guide EWS-150g Configuration Guide Installing the EWS-150g This User’s Guide is intended for use by Service Providers who are pre-configuring the device for their subscribers. The physical installation of the EWS-150g is performed by the subscriber. It is the subscriber’s responsibility to ensure that the unit is connected to their computer or home network properly, using the components provided. The following items are shipped in the product’s carton: ◗ 1 x Strix EWS-150g unit ◗ 1 x Ethernet cable, 5ft length (blue) ◗ 2 x Omni-directional antennas ◗ 1 x Power supply Factory Default Settings The following table shows the default settings established at the factory for the EWS-150g. Function Factory Default Setting IP Address 169.254.1.250 User Name Admin Password Admin 802.11g Radio SSID Enabled, and configured as a wireless client station. Strix Wireless Network The EWS-150g will always connect to the Strix Wireless Network SSID, when available. DHCP Enabled Layer 2 NAT Enabled Accessibility Accessible via the Ethernet port Manager/One Plug-In Enabled Resetting the EWS-150g to its Factory Default State To reset the EWS-150g to its factory default state, use a paper clip—or other similar tool—to press the Reset button (see Figure 2) on the rear panel. Hold the Reset button down until the LEDs on the front panel go OFF and the Power (PWR) LED comes ON again (about 5 seconds) to restore all configuration settings to their factory default values. EWS-150g Configuration Guide EWS-150g Configuration Guide Managing the EWS-150g The EWS-150g is preconfigured for basic functionality by the WISP using the unit’s embedded Web Management Interface (WMI). The unit can also be configured remotely. This User’s Guide describes how to configure and monitor your EWS-150g using its embedded Web Management Interface. Connecting to the Unit Use an Ethernet cable (provided) to connect the EWS-150g to a computer. Alternatively, you can connect the unit to the computer via an Ethernet switch, hub or router. If the network is using a DHCP server, the unit will be assigned an IP address automatically (even when DHCP assigns an IP address the unit can always be reached from its default IP address, which is 169.254.1.250). If no DHCP server is available, the unit can only be reached via its default IP address (169.254.1.250). To establish a connection, the EWS-150g and your computer must be on the same IP segment. Use your Web browser to connect with the EWS-150g. ◗ When using a DHCP server, you can identify the IP address assigned by the server by looking in the log files of the DHCP server, or by using the Strix Manager/One plug-in; however, the Manager/One plugin is only compatible with Microsoft® Internet Explorer, version 6.1 or higher. You can download the plug-in from http://www.strixsystems.com/support/downloads.asp. ◗ If no DHCP server is available, use the unit’s default IP address (169.254.1.250). Logging In At the Login prompt, use the default user name and password to log in to the EWS-150g. The default user name and password is Admin (for both). After entering the user name and password, click on the OK button to log in to the unit’s Web Management Interface. Figure 3. Login Prompt EWS-150g Configuration Guide EWS-150g Configuration Guide The Home Page With a successful login, the EWS-150g home page is displayed. The home page shows the unit’s current status information. It also provides information about the top wireless neighbors that are within range of the radio, as well as system details (IP address, MAC address, uptime and firmware version). A selection of buttons in the left pane of the home page provides immediate access to system monitoring information (Quick Links), and a choice of tools for resetting the unit to its factory default state, loading new firmware and rebooting the unit (Actions). The top 2 frames of the home page containing the station and wireless neighbor information will refresh themselves automatically every 10 seconds, but you can force a refresh of these frames at any time by clicking on the Refresh button. The bottom frame containing the unit’s statistical data can be refreshed manually by clicking on the Refresh button (this frame does not refresh itself automatically). Tabbed Windows (Home/Configure/Monitor) Refresh Left Pane Figure 4. Home Page From the home page you can click on either the Configure tab to access the unit’s configuration options, or click on the Monitor tab to view the current operational status of the unit. You can return to the home page at any time by simply clicking on the Home tab. EWS-150g Configuration Guide EWS-150g Configuration Guide About the Country Code The EWS-150g uses the US (United States) as the default country code. You are solely responsible for setting the correct country code to ensure full compliance with your local regulatory laws for wireless communications. Only the US and Canada are presented in the list of available country codes. To set the country code, click on the Configure tab then click on General to display the General Settings window. Figure 5. General Settings Window In the Country Code field, select the country code from the pull down list that applies to your geographic location (either the United States or Canada). All examples from this point forward assume that the US is your country of choice. If you change the country code to Canada you are presented with a warning to remind you that it is your responsibility to comply with your local regulatory laws for wireless communications. You must click on the OK button to acknowledge that you understand your responsibility. Figure 6. Warning If you change the country code, click on Update to apply your change then click on Reboot to reboot the EWS-150g. Only after the unit reboots will your selected country code become active. EWS-150g Configuration Guide EWS-150g Configuration Guide Setting Up the User Login Parameters Establishing user login parameters determines both the administrator and guest user privileges. To set up these parameters, click on the Configure tab then click on User Login to display the User Login window. Figure 7. User Login Window 1. In the User Name field, select the type of user (either Admin or Guest) from the pull-down list. 2. In the Password field, enter a password (between 5 and 32 characters). The password is casesensitive. 3. In the Confirm Password field, retype your password (otherwise the system will reject it). The default for the user name and the password is Admin (with a capitalized A) for both. We strongly recommend that you change the default password immediately after your initial login. 4. In the Guest User Login field, check the enabled box if you want to allow guest access. Leave this box unchecked to deny all guess access. 5. When finished, click on Update to apply your changes then click on Reboot to reboot the EWS-100. Only after the unit reboots will the user login parameters you defined here be in effect. EWS-150g Configuration Guide EWS-150g Configuration Guide Setting Up the System Management Options The EWS-150g can be managed from any of the following management options: ◗ Web—from your Web browser using its embedded Web Management Interface (WMI). ◗ LAN—This option allows you to manage the EWS-150g using either Web, Telnet or SNMP with a direct connection from the unit’s LAN port. ◗ SNMP—Allows management via an SNMP (Simple Network Management Protocol) management console. The EWS-150g supports the 802.11 MIB (Management Information Base), as well as Strix proprietary MIBs. Any MIB I or MIB II compliant SNMP management console (such as HP OpenView) can be used to manage the unit. To set up the system management options, click on the Configure tab then click on Management to display the Management window. Figure 8. Management Window Enable or disable your preferred system management options, as desired. If you enable the Telnet option you must also provide the Telnet timeout (in seconds)—the default is 180. If you enable SNMP management, you must also provide the SNMP communities you are using and the system contact information. When finished, click on Update to apply your changes then click on Reboot to reboot the EWS-150g. Only after the unit reboots will you be able to manage the EWS-150g from any of the selected management options. EWS-150g Configuration Guide EWS-150g Configuration Guide Establishing the TCP/IP Network Settings You have the option of obtaining all IP addresses (unit, default gateway, DNS server and SNTP server) automatically using DHCP, or you can configure static IP addresses manually. The default is to have the DHCP server assign all IP addresses. In addition, there is an option to enable or disable DHCP functionality over the LAN port. The default is to have this option enabled so that DHCP can assign IP addresses for the initial configuration; however, after completing the TCP/IP configuration you must disable this option to prevent the reassignment of IP addresses over the unit’s Ethernet port—see also, DHCP Over LAN (below). To set up the TCP/IP options, click on the Configure tab then click on TCP/IP to display the TCP/IP Settings window. Figure 9. TCP/IP Settings Window If you want to assign any IP addresses manually (static IP addresses), enter the addresses in the corresponding fields, otherwise allow DHCP to assign the addresses for you. DHCP Over LAN This option should be checked (enabled) during the initial configuration process, but when you have completed the TCP/IP configuration and all IP addresses have been assigned you must disable this option to prevent users from reassigning IP addresses over the unit’s Ethernet port. When finished, click on Update to apply your changes then click on Reboot to reboot the EWS-100. Only after the unit reboots will the IP addresses defined by your TCP/IP configuration options be in effect. Disable the DHCP over LAN option! EWS-150g Configuration Guide EWS-150g Configuration Guide Setting Up the Radio Parameters To set up the 802.11g radio parameters, click on the Configure tab then click on Radio Parameters to display the 802.11g Radio Parameters window. Figure 10. Radio Parameters Window 1. In the Data Rate field, choose the preferred data rate from the pull-down list. The default for this field is Best, which means the EWS-150g will select the best data rate available automatically. 2. In the Transmit Power field, choose the preferred transmit power from the pull-down list (either Full, Half, Quarter, One Eighth, or Minimum). The default for this field is Full, which means the radio is always operating at full (maximum) power. 3. In the Background Scan Enabled field, check this box to enable background scanning for wireless client stations. the default for this field is enabled. 4. In the Background Scan Interval field—If you enabled background scanning—enter a value between 1000 and 60000 ms to define the interval (elapsed time) between scans. The default for this field is 5000 milliseconds. 5. In the Background Scan Duration field—If you enabled background scanning—enter a value between 10 and 10000 ms to define the duration of each scan. The default for this field is 50 milliseconds. 6. In the Fragment Length field, enter a value between 256 and 2346. This setting determines the size of the wireless frame. Wireless frames are reassembled by the EWS-150g before being forwarded to the Ethernet port, but only if the frame is smaller than the Ethernet MTU (1536 bytes). The default value for this field is 2346. 10 EWS-150g Configuration Guide EWS-150g Configuration Guide 7. In the RTS/CTS Threshold field, enter a value between 256 and 2346. This value determines at what frame length the RTS-CTS function is triggered. By default, the threshold is set at its highest value (2346). A lower value means that the RTS-CTS function is triggered for smaller frame lengths. A lower threshold value may be necessary in environments with excessive signal noise, but may result in some performance degradation. 8. In the Protection Mode field, choose the desired 802.11g protection mode from the pull-down list (either Auto, None or Always). The default for this field is Auto. ◗ Auto—This is the default mode and will enable protection for 802.11g stations if the EWS-150g finds an 802.11b client. In this mode, if the 802.11b client leaves the network the protection mode will revert to None automatically. ◗ None—This assumes there are no wireless stations using 802.11b (11 Mbps) technology. If operating in a mixed 802.11b/g network with minimal 802.11b traffic, choose this option to ensure the best performance for your 802.11g stations. ◗ Always—Protects 802.11b traffic from colliding with 802.11g traffic. This mode is not recommended, especially if only a few wireless stations are operating with 802.11b. Only use this mode in environments with heavy 802.11b traffic or where there is interference. 9. In the Protection Rate field, choose the data rate at which the RTS-CTS (Request-to-Send and Clearto-Send) packets are sent (either 1 Mbps, 2 Mbps, 5.5 Mbps, or 11 Mbps). The default data rate for this field is 11 Mbps. 10. In the Protection Type field, choose either CTS-only or RTS-CTS. With CTS-only selected, the client is not required to send an RTS (Request-to-Send) to the AP. As long as the client receives a CTS (Clearto-Send) frame from the AP then the client is free to send data. With the RTS-CTS option enabled, the client is required to send an RTS to the AP and wait for a CTS from the AP before it can send data (this option creates additional overhead and can cause performance degradation). The default for this field is CTS-only. 11. In the Short Slot Time field, check the box to enable this feature. 802.11g defines the long slot time as 20 microseconds and a short slot time as 9 microseconds. 802.11b only supports the long slot time of 20 microseconds. In an environment with 802.11g devices only, this option (Short Slot Time) must be enabled for better performance—giving precedence to 802.11g traffic. The default is to have the short slot time enabled. 12. In the Short Preamble field, check the box to enable this feature. Short slot preamble improves network efficiency by reducing the preamble from 128 bits to 56 bits. 802.11g is required to support both short and long preambles (802.11b support for a short preamble is optional). If this option is enabled, any 802.11b clients associated with the network must support a short preamble. The default is to have the short preamble enabled. 13. When finished, click on Update to apply your changes then click on Reboot to reboot the EWS-150g. Only after the unit reboots will these changes take effect. EWS-150g Configuration Guide 11 EWS-150g Configuration Guide Station Configuration To establish the 802.11g Station Configuration parameters, click on the Configure tab then click on Configuration to display the 802.11g Station Configuration window. Figure 11. Station Configuration Window 1. In the AP Selection Method field, choose either BSSID or SSID as the AP selection priority. If BSSID is selected and the EWS-150g cannot locate the BSSID within the elapsed time specified in the BSSID Timeout field, the unit defaults to the SSID. The default for this field is SSID. 2. If BSSID is selected as the AP selection method, enter the MAC address of the AP in the BSSID field. 3. If BSSID is selected as the AP selection method, enter a value (in seconds) in the BSSID Timeout field to define the elapsed time before the EWS-150g defaults to the SSID to locate the AP. 4. In the SSID field, enter the SSID of the network that you want to grant client access to. 5. In the Authentication field, choose the desired level of authentication. Client authentication ensures that users are who they say they are. If authentication is required (strongly recommended), you must define the level of authentication you want to assign to this Access Point. Currently, not all authentication types are available with the EWS-150g. The default for this field is Open. 6. The EAP Type is currently not supported. 7. In the Encryption field, choose either Clear or WEP (other encryption methods are currently not supported). The default for this field is Clear. 12 EWS-150g Configuration Guide EWS-150g Configuration Guide 8.
