7.11.6 Preamble Type
Preamble is used to signal that data is coming to the receiver. Short and long refer to the length of the
synchronization field in a packet.
Short preamble increases performance as less time sending preamble means more time for sending
data. All IEEE 802.11 compliant wireless adapters support long preamble, but not all support short
preamble.
Use long preamble if you are unsure what preamble mode other WiFi devices on the network support,
and to provide more reliable communications in busy WiFi networks.
Use short preamble if you are sure all WiFi devices on the network support it, and to provide more
efficient communications.
Use the dynamic setting to automatically use short preamble when all WiFi devices on the network
support it, otherwise the Zyxel Device uses long preamble.
Note: The WiFi devices MUST use the same preamble mode in order to communicate.
7.11.7 WiFi Protected Setup (WPS)
Your Zyxel Device supports WiFi Protected Setup (WPS), which is an easy way to set up a secure WiFi
network. WPS is an industry standard specification, defined by the WiFi Alliance.
