
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.

Data Rate (Mbps): Selects the data rate or the modulation and coding scheme (MCS). The default
setting of Auto is recommended. 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.)
If the goal is securing your network, use WPA or preferably WPA2 encryption. Hiding the ESSID does

2.4.5.2.2 WDS
A Wireless Distribution System (WDS) is a system enabling the wireless interconnection of access points
in an IEEE 802.11ac network. It allows a wireless network to be expanded using multiple 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.
