and communicate with each other. When Intra-BSS traffic blocking is enabled,
wireless station A and B can still access the wired network but cannot
communicate with each other.

6.7.5 MBSSID
Traditionally, you need to use different APs to configure different Basic Service
Sets (BSSs). As well as the cost of buying extra APs, there is also the possibility of
channel interference. The ZyXEL Device’s MBSSID (Multiple Basic Service Set
IDentifier) function allows you to use one access point to provide several BSSs
simultaneously. You can then assign varying QoS priorities and/or security modes
to different SSIDs.
Wireless devices can use different BSSIDs to associate with the same AP.
6.7.5.1 Notes on Multiple BSSs
• A maximum of eight BSSs are allowed on one AP simultaneously.
• You must use different keys for different BSSs. If two wireless devices have
different BSSIDs (they are in different BSSs), but have the same keys, they
may hear each other’s communications (but not communicate with each other).
• MBSSID should not replace but rather be used in conjunction with 802.1x
security.
6.7.6 WiFi Protected Setup (WPS)
Your ZyXEL Device supports WiFi Protected Setup (WPS), which is an easy way to
set up a secure wireless network. WPS is an industry standard specification,
defined by the WiFi Alliance.
