Overview

This module enables you to set SSID-related parameters of the AP.
Broadcast SSID
When the AP broadcasts an SSID, nearby wireless clients can detect the SSID. When this parameter is set to
Disable, the AP does not broadcast the SSID and nearby wireless clients cannot detect the SSID. In this case,
you need to enter the SSID manually on your wireless client if you want to connect to the wireless network
corresponding to the SSID. It enhances the security of the wireless network.
It is worth noting that after Broadcast SSID is set to Disable, a hacker can still connect to the corresponding
wireless network if he/she manages to obtain the SSID by other means.
Isolate Client
This parameter implements a function similar to the VLAN function for wired networks. It isolates the wireless
clients connected to the same wireless network corresponding to an SSID, so that the wireless clients can
access only the wired network connected to the AP. Applying this function to hotspot setup at public places
such as hotels and airports helps increase network security.
WMF
The number of wireless clients keeps increasing currently, but wired and wireless bandwidth resources are
limited. Therefore, the multicast technology, which enables single-point data transmission and multi-point data
reception, has been widely used in networks to effectively reduce bandwidth requirements and prevent
network congestion.
Nevertheless, if a large number of clients are connected to a wireless interface of a wireless network and
multicast data is intended for only one of the clients, the data is still sent to all the clients, which unnecessarily
increases wireless resource usage and may lead to wireless channel congestion. In addition, multicast stream
forwarding over an 802.11 network is not secure.
The WMF function of the AP converts multicast traffic into unicast traffic and forwards the traffic to the
multicast traffic destination in the wireless network. This helps save wireless resources, ensure reliable
transmission, and reduce delays.
