Utility Setup Screen shots will vary depending on your version of Windows. Insert the Support CD-ROM into your CD-ROM drive and run the setup. exe file. Follow the on-screen instructions. Step 2. Click Finish to complete the utility installation. Utility Setup and Configuration 4-1 ZyAIR 200 Wireleass LAN USB Adapter Step 3. Proceed to the next section to configure your ZyAIR 200. 4. 2 Utility Configuration Your ZyAIR 200 is Plug-and-Play and its default settings can be set for a typical infrastructure wireless LAN. Simply install the ZyAIR 200 onto your computer and it is ready for use. In special circumstances however, you may need to change configuration settings depending on how you want to manage your wireless network. The ZyAIR 200 Utility enables you to make configuration changes and perform userlevel diagnostics. The utility window will display as shown next. 4-2 Utility Setup and Configuration ZyAIR 200 Wireless LAN USB Adapter Figure 4-1 Utility ­ Status 4. 2. 1 Utility Screen Configure and monitor your ZyAIR 200 using the following utilities: Status, Counter, AP Browser, Configuration, Encryption and About. 4. 2. 2 Status The Status window displays the current state of your ZyAIR 200.

Displays the MAC address of the Access Point your ZyAIR 200 is associated with This bar graph displays the signal strength as reported by the radio, averaged over all frames that are received from the Access Point Monitors the quality of the data transmission between your ZyAIR 200 and an Access Point. Link Quality 4. 2. 3 Counter Statistical information on instantaneous wireless receive and transmit throughput in bytes per second is displayed. Figure 4-2 Utility ­ Counter 4-4 Utility Setup and Configuration ZyAIR 200 Wireless LAN USB Adapter 4. 2. 4 AP Browser The following table explains the status/statistical information found in the Access Point Browser screen. Preamble Type This field allows two different selections: Long and Short. Long ­ The mandatory supported "Long preamble as well as header" as specified in IEEE802. 11 that allows interoperation with the current 1Mbit/sec and 2Mbit/sec DSSS specification. Utility Setup and Configuration 4-7 ZyAIR 200 Wireleass LAN USB Adapter Short ­ The optional "Short preamble and header" is intended for applications where maximum throughput is desired and interoperability with legacy and non-short preamble capable equipment is not a consideration. Hidden Node is a situation in which two stations are within range of the same Access Point, but are not within range of each other. The following figure illustrates an example of the Hidden Node problem. Both stations (STA) are within range of the Access Point, however, they cannot hear each other. When a station starts data transmission with the Access Point, it might not notice that the other station is already using the wireless medium. When these two stations send data at the same time, they might collide when arriving simultaneously at the Access Point. The collision will most certainly result in a loss of messages for both stations. Figure 4-5 RTS Threshold Thus, the RTS Threshold mechanism provides a solution to prevent data collisions. When you enable RTS Threshold on a possible hidden station, this station and its Access Point will use a Request to Send/Clear to Send protocol (RTS/CTS). The station will send an RTS to the Access Point, informing that it is going to transmit the data. Upon receipt, the Access Point will respond with a CTS message to all stations within its range to notify all other stations to defer transmission.
