[. . . ] TCP/IP should already be installed on computers using Windows NT/2000/XP, Macintosh OS 7 and later operating systems. 3. 1 Windows 2000/NT/XP 1. Select Internet Protocol (TCP/IP) (under the General tab in Win XP) and click Properties. The Internet Protocol TCP/IP Properties screen opens (the General tab in Windows XP). Configure your computer to use a static IP address, select Use the following IP Address and fill in the IP address (192. 168. 1. 3 to 192. 168. 1. 254) and Subnet mask (255. 255. 255. 0) fields. 6. [. . . ] Setting this attribute to be larger than the maximum MSDU (MAC service data unit) size turns off the RTS/CTS handshake. The threshold (number of bytes) for the fragmentation boundary for directed messages. As the wireless station moves from place to place, it is responsible for choosing the most appropriate access point depending on the signal strength, network utilization or other factors. 13 ZyAIR G-1000 Access Point The roaming feature on the access points allows the access points to relay information about the wireless stations to each other. When a wireless station moves from a coverage area to another, it scans and uses the channel of a new access point, which then informs the access points on the LAN about the change. The new information is then propagated to the other access points on the LAN. If the roaming feature is not enabled on the access points, information is not communicated between the access points when a wireless station moves between coverage areas. The wireless station may not be able to communicate with other wireless stations on the network and vice versa. Figure 3 Roaming Example To enable roaming on your ZyAIR, click WIRELESS, then the Roaming tab. The screen appears as shown. 14 ZyAIR G-1000 Access Point Figure 4 Roaming The following table describes the fields in this screen. Table 3 Roaming LABEL Active DESCRIPTION Select Yes from the drop-down list box to enable roaming on the ZyAIR if you have two or more ZyAIRs on the same subnet. All APs on the same subnet and the wireless stations must have the same ESSID to allow roaming. Port Apply Reset Enter the port number to communicate roaming information between APs. Click Reset to begin configuring this screen afresh. 5. 4 Configuring IEEE 802. 1x Authentication You can set the ZyAIR and your network to authenticate a wireless station before the wireless station can communicate with the ZyAIR and the wired network to which the ZyAIR is connected. Your ZyAIR supports the Institute of Electrical and Electronics Engineers (IEEE) 802. 1x standard that works with IEEE 802. 11 to enhance user authentication. To change your ZyAIR's authentication settings, click WIRELESS, then the 802. 1x tab. The screen appears as shown. 15 ZyAIR G-1000 Access Point Figure 5 Wireless 802. 1x Authentication The following table describes the fields in this screen. Table 4 Wireless 802. 1x Authentication LABEL Wireless Port Control DESCRIPTION To control wireless stations access to the wired network, select a control method from the drop-down list box. Choose from No Authentication Required, Authentication Required and No Access Allowed. No Authentication Required allows all wireless stations access to the wired network without entering usernames and passwords. Authentication Required means that all wireless stations have to enter usernames and passwords before access to the wired network is allowed. No Access Allowed blocks all wireless stations access to the wired network. ReAuthentication Timer Specify how often wireless stations have to reenter usernames and passwords in order to stay connected. This field is activated only when you select Authentication Required in the Wireless Port Control field. The default time interval is 1800 seconds (30 minutes). If wireless authentication is done using a RADIUS server, the reauthentication timer on the RADIUS server has priority. 16 ZyAIR G-1000 Access Point Table 4 Wireless 802. 1x Authentication LABEL Idle Timeout DESCRIPTION The ZyAIR automatically disconnects a wireless station from the wired network after a period of inactivity. The wireless station needs to enter the username and password again before access to the wired network is allowed. [. . . ] Hang the ZyAIR on the screws. 21 ZyAIR G-1000 Access Point Figure 9 Hanging the ZyAIR 22 ZyAIR G-1000 Access Point 7 Troubleshooting PROBLEM The PWR LED is off. CORRECTIVE ACTION Make sure you are using only the supplied power adaptor and the power adaptor is plugged into an appropriate power supply. I cannot access the web configurator. Check the cable connection to the ZyAIR's ETHERNET port. Make sure the IP addresses and subnet masks of the ZyAIR and the computer are in the same IP address range. (For example, if the ZyAIR is using the default IP address and subnet mask, check that the IP address of the computer is in the range 192. 168. 1. 3 ~192. 168. 1. 254 and the subnet mask is 255. 255. 255. 0).
