Network Control Panel Applet (NCPA)
IBSS (802.11 Ad Hoc) - Select IBSS (802.11 Ad Hoc) to
enable MUs to form their own local network where MUs
communicate peer-to-peer without access points. Use
IBSS to create networks where needed within established
cells. In IBSS, MUs take turns generating beacons and
handling probe responses. The MU starting the IBSS
network (the first station transmitting a beacon)
determines the channel and data rate used for the IBSS
network. If a single MU is sending every beacon, there
are no other MUs in the IBSS network and at least one
more MU is needed to communicate peer-to-peer.
Pseudo IBSS (Proprietary Ad Hoc) - Select Pseudo IBSS
when the highest throughput is required in an IBSS
network for testing MUs. Pseudo IBSS does not support
PSP MUs and does not use beacons or authentication.
In Pseudo IBSS mode, each MU is required to be on the
same channel. Pseudo IBSS is not recommended as a
normal operational mode or for MUs operating on
battery power.
Enter an ESSID in the 802.11 ESSID field. The ESSID is
the 802.11 Extended Service Set Identifier. The ESSID is
a 32-character (maximum) string identifying the wireless
local area network. The ESSID assigned to the adapter
is required to match the access point ESSID for the
adapter to communicate with the access point. The
ESSID can also be entered from the Easy Setup window.
Use the Mandatory AP address field to enter the IEEE
MAC address of the access point where the adapter is
required to associate. The adapter associates to only
this access point when communicating on the network.
Enter an access point MAC address to associate to an
access point that has a compatible ESSID.
