Enterasys Networks RBTSA-AB, RBTSA-AA manual External and one internal antenna- this setting

Using the Configuration Management System 35

Table 11 Wireless Network Page (continued)

Setting	Description
Antenna Selection	Select an antenna for the radio signal:
	■ Internal—this default setting should be used in most
	circumstances.
	■ External and one internal antenna—this setting
	automatically determines which antenna is best for sending
	packets to individually attached clients. Choose this setting
	if the Ethernet Adapter is located in a place that is
	surrounded or hindered by metal paths or walls.
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).
	Note: The Data Preamble option is available in ad-hoc mode
	only. However, the Short Data Preamble option is not available
	for 802.11a and 802.11a Turbo modes in ad-hoc mode.

Manually Selecting On the Advanced Wireless Network page, you can manually select the Radio Channels radio channels and radio modes. The Ethernet Adapter only looks for a

best SSID that matches the specified radio mode on the specified channels.

Setting Up an Ad-HocOperating in ad-hoc mode, two or more Ethernet Adapters can associate Network among themselves to form an ad-hoc network without the intervention

of an access point. You may wish to set up an ad-hoc network, for example, if a group is working away from the office, or if a group in the office needs to share files apart from the wired LAN.

CAUTION: To ensure correct operation, the settings on the two Ethernet Adapters must match exactly. To avoid the possibility of losing wireless association while you are configuring, Enterasys Networks recommends that you connect the Ethernet Adapter directly to the computer.

VORSICHT: Um einen fehlerfreien Betrieb zu gewährleisten, müssen die Einstellungen auf den beiden Ethernet-Adaptern genau übereinstimmen. Es wird empfohlen, den Ethernet-Adapter direkt mit dem Computer zu verbinden, um während der Konfiguration die drahtlose Verbindung nicht zu verlieren.
