SETTING ADVANCED PERFORMANCE PROPERTIES

Under System Configuration, click Wireless Network. On the Wireless Network Properties page, click the link to go to advanced wireless network configuration. The Advanced Wireless Network page appears, where you can change the settings listed below. When you are finished, click Save.

Network Traffic Accelerator—To increase performance, click On (Enhanced performance). If you experience problems when equipment other than 3Com 11 Mbps Wireless LAN equipment is being used, click Off (Wi-Fi Interoperable).

Data Preamble—To increase performance, click Short (Enhanced performance). When equipment that does not support short preamble is also being used, click Long (Wi-Fi Interoperable).

Flow Control—When there is a great deal of traffic on the wireless LAN, flow control can prevent bridge input buffers from overflowing, thereby increasing WLAN reliability. The bridge supports IEEE 802.3x asymmetric outgoing flow control, allowing it to pause the transmission of data frames from a switch or router that is operating in full-duplex mode and supports 10/100
