• DHCP Relay : Enable DHCP Relay agent to convert broadcast DHCP messages
to unicast in Tunnel Mode WLANs. For more information, see Configuring DHCP
Relay .
• Background Scanning : Background scanning enables the Ruckus Wireless
access points to continually scan for the best (least interference) channels and
adjust to compensate. However, disabling Background Scanning may provide
better quality (lower latency) for time-sensitive applications like voice conversa-
tions. If this WLAN will be used primarily as a voice network, select this check
box to disable Background Scanning for this WLAN. You can also disable
Background Scanning per radio (see
Background Scanning ).
• Load Balancing : Client load balancing between APs is disabled by default on all
WLANs. To disable load balancing for this WLAN only (when enabled globally),
check this box. Ruckus Wireless recommends disabling load balancing on VoIP
WLANs. For more information, see
Load Balancing .
• Band Balancing : Client band balancing between the 2.4 GHz and 5 GHz radio
bands is disabled by default on all WLANs. To disable band balancing for this
WLAN only (when enabled globally), check this box. For more information see
Band Balancing .
• Max Clients : Limit the number of clients that can associate with this WLAN per
AP radio (default is 100). You can also limit the total number of clients per AP
using the AP Groups settings. See
Modifying Model Specific Controls for more
information.
• 802.11d : The 802.11d standard provides specifications for compliance with
additional regulatory domains (countries or regions) that were not defined in the
original 802.11 standard. Enable this option if you are operating in one of these
additional regulatory domains. For optimal performance of Apple iOS devices, it
is recommended that you enable this option. Please be aware that some legacy
embedded devices such as wireless barcode scanners may not operate properly
if this option is enabled. This option is enabled by default for any WLANs created
on ZoneDirector version 9.6 or later, and disabled by default for any WLANs
created running earlier versions. If upgrading from a previous version to 9.6 or
later, existing WLANs will retain their original settings.
• DHCP Option 82 : When this option is enabled and an AP receives a DHCP
request from a wireless client, the AP will encapsulate additional information
(such as VLAN ID, AP name, SSID and MAC address) into the DHCP request
packets before forwarding them to the DHCP server. The DHCP server can then
