ZyAIR
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.
5.3Preamble Type
A preamble is used to synchronize the transmission timing in your wireless network. There are two preamble modes: long and short.
Short preamble takes less time to process and minimizes overhead, so it should be used in a good wireless network environment when all wireless clients support it.
Select Long if you have a ‘noisy’ network or are unsure of what preamble mode your wireless clients support as all IEEE 802.11b compliant wireless adapters must support long preamble. However, not all wireless adapters support short preamble. Use long preamble if you are unsure what preamble mode the wireless adapters support, to ensure interpretability between the ZyAIR and the wireless stations and to provide more reliable communication in ‘noisy’ networks.
Select Dynamic to have the ZyAIR automatically use short preamble when all wireless clients support it, otherwise the ZyAIR uses long preamble.
The ZyAIR and the wireless stations MUST use the same preamble mode in orderto communicate.5.4Configuring Wireless
