Setting Up an Ad-Hoc
Network
Operating in ad-hoc mode, two or more Ethernet Adapters can associate
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.
