Rates 4. 2. 5 Configuration The Configuration menu allows you to view and modify the current configurations of your ZyAIR 200 easily and quickly. The configuration settings include: SS ID, Network Type, Tx(Transmission) Rate, Preamble Type, RTS/CTS Threshold, and Fragmentation Threshold. Figure 4-4 Utility ­ Configuration 4-6 Utility Setup and Configuration ZyAIR 200 Wireless LAN USB Adapter Network Type To connect your wireless station to a local network infrastructure, set the station operation mode to Infrastructure (with Access Point as default setting). In case you do not wish to connect to a network infrastructure, but prefer to set up a small wireless workgroup, you can enable the Ad-hoc (without Access Point). When the Ad-hoc mode is selected, be sure to set your wireless stations with the same channel. ZyAIR 200 works with any IEEE 802. 11 and 802. 11(b)-compliant Access Points. Channel Channel allows you to choose the radio channels depending on your geographical area. When your Network Type is set to Ad-Hoc mode, be sure to select your wireless computer with the same channel. Wireless clients associating to any Access Point must have the same SSID. Select SSID and enter a specific SSID (Access Point) you desire to connect with. This allows your wireless adapter to automatically associate to any Access Point that gives the fastest response. This will prevent your computer from accidentally connecting to a different wireless network. Tx(Transmission) Rate ZyAIR 200 provides various transmission (data) rate options for you to select. Transmission Rate options include Fully Auto, Fixed 1 Mb/s, Fixed 2 Mb/s, Auto Select 1M or 2M, Fixed 5. 5Mb/s and Fixed 11Mb/s. In most networking scenarios, you will see that the factory default Fully Auto will prove the most efficient. This setting allows your ZyAIR 200 to operate at the maximum transmission (data) rate. When the communication quality drops below a certain level, ZyAIR 200 will automatically switch to a lower transmission (data) rate. However, when the communication quality improves again, ZyAIR 200 will gradually increase the transmission (data) rate again until it reaches the highest available transmission rate. If you wish to balance speed versus reliability, you can select any of the above options. Fixed 11Mb/s or Fixed 5. 5Mb/s is used in a networking environment where you are certain that all wireless devices can communicate at the highest transmission (data) rate. Fixed 1Mb/s, Fixed 2Mb/s, Auto Select 1M or 2M are used often in networking environments where the range of the wireless connection is more important than speed. Preamble Type This field allows two different selections: Long and Short.
