Note: Setting more than 1 station on a board is
not supported because there can only be one default
gateway. Both 2.4 and 5 GHz radios cannot be in
Station mode at the same time.
ESSID: Specifies the name or extended service set
identifier (ESSID) of the wireless network as it is
provided in the beacon message. The network name
can be up to 32 characters in length and can contain
spaces. When running in AP mode, it is the name of
the network as advertised in the beacon message. In
Station mode, it is the network name that the station
associates with.
BSSID: Sets the MAC address of the AP. This option is
available for a device operating as a station. This is
useful because there can be multiple APs with the
same ESSID. Setting the MAC address would prevent
the station from roaming to other APs.
Guard Interval: Chooses between Short and Long
guard intervals. Guard intervals are used to ensure
that distinct transmissions do not interfere with one
another. Data rate is improved in downlink and uplink
if both AP and station use the Short Guard Interval.
Long Guard Intervals can improve performance in
high multipath environments with a small reduction
in maximum data rate.
Data Rate (Mbps): Selects the data rate or the
modulation and coding scheme (MCS). The default
setting of Auto is recommended for all profiles. The
MCS and data rates are adjusted automatically
depending on the wireless channel conditions.
Hide ESSID: Hides the network name (ESSID) from
being broadcast publicly. (This option is for a device
operating as an AP.)
Note: If the goal is securing your network, use
WPA or preferably WPA2-PSK encryption. Hiding the
ESSID does not provide complete security.
WDS
A Wireless Distribution System (WDS) is a system
enabling the wireless interconnection of access points
in an IEEE 802.11 network. It allows a wireless
network to be expanded using access points without
the traditional requirement for a wired backbone to
link them. The notable advantage of WDS over other
solutions is it preserves the MAC addresses of client
frames across links between access points.
WDS may also be considered a repeater mode
because it appears to bridge and accept wireless
clients at the same time (unlike traditional bridging).
However, with this method, throughput is halved for
all clients connected wirelessly.
Setup for the WDS Modes
The wireless distribution system (WDS) allows the
Station WDS to bridge wireless traffic transparently,
providing the functionality of a repeater. The Station
WDS is a transparent client and would need to
associate with an AP WDS. The WDS protocol is not
defined as a standard so there may be compatibility
issues between devices from different vendors. The
following figures show an example of a setup.

WDS mode.

mode.
