ZyAIR
Enabling the RTS Threshold causes redundant network overhead that could negatively affect the throughput performance instead of providing a remedy.
18.2.4 Fragmentation Threshold
A Fragmentation Threshold is the maximum data fragment size (between 256 and 2432 bytes) that can be sent in the wireless network before the ZyAIR will fragment the packet into smaller data frames.
A large Fragmentation Threshold is recommended for networks not prone to interference while you should set a smaller threshold for busy networks or networks that are prone to interference.
If the Fragmentation Threshold value is smaller than the RTS/CTS value (see previously) you set then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented before they reach RTS/CTS size.
18.2.5 Preamble Type
A preamble is a signal used to synchronize the transmission timing in your wireless network. There are two preamble modes: Long and Short.
Long preamble mode allows more processing time for each transmitted data packet. Short preamble mode allows less processing time for the transmitted data packets.
Using short preamble mode may minimize overhead and maximize network throughput. However, short preamble mode is supported by IEEE 802.11b compliant wireless devices, thus wireless stations using short preamble mode cannot communicate with wireless stations using the original IEEE 802.11 standard.
18.3 Wireless LAN Setup
If you are configuring the ZyAIR from a computer connected to the wireless LAN and you change the ZyAIR’s ESSID or WEP settings, you will lose your wireless connection when you press Apply to confirm. You must then change the wireless settings of your computer to match the ZyAIR’s new settings.
Click ADVANCED SETUP and then WIRELESS to open the Wireless screen.
