 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. This to some extent enhances
the security of the wireless network.
4UZK
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. Therefore, disabling this function only ensures low network security.
Client Isolation
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.
