General Settings
Activate
Select this option to make this profile active.
Profile Name
Enter up to 31 alphanumeric characters to be used as this profile’s name. Spaces and
underscores are allowed.
Schedule
This field displays the schedule object which defines when this radio profile can be used.
802.11 Band
Select how to let wireless clients connect to the AP.
•
11b/g
: allows either IEEE 802.11b or IEEE 802.11g compliant WLAN devices to associate
with the AP. The AP adjusts the transmission rate automatically according to the
wireless standard supported by the wireless devices.
•
11b/g/n
: allows IEEE802.11b, IEEE802.11g and IEEE802.11n compliant WLAN devices to
associate with the AP. The transmission rate of your AP might be reduced.
•
11a
: allows only IEEE 802.11a compliant WLAN devices to associate with the AP.
•
11a/n
: allows both IEEE802.11n and IEEE802.11a compliant WLAN devices to associate
with the AP. The transmission rate of your AP might be reduced.
•
11ac
: allows only IEEE802.11ac compliant WLAN devices to associate with the AP.
Channel Width
Select the wireless channel bandwidth you want the AP to use.
A standard 20 MHz channel offers transfer speeds of up to 144Mbps (2.4GHz) or 217Mbps
(5GHZ) whereas a 40MHz channel uses two standard channels and offers speeds of up to
300Mbps (2.4GHz) or 450Mbps (5GHZ). An IEEE 802.11ac-specific 80MHz channel offers
speeds of up to 1.3Gbps.
40 MHz (channel bonding or dual channel) bonds two adjacent radio channels to increase
throughput. A 80 MHz channel consists of two adjacent 40 MHz channels. The wireless
clients must also support 40 MHz or 80 MHz. It is often better to use the 20 MHz setting in a
location where the environment hinders the wireless signal.
Because not all devices support 40 MHz and/or 80 MHz channels, select
20/40MHz
or
20/
40/80MHz
to allow the AP to adjust the channel bandwidth automatically.
Select
20MHz
if you want to lessen radio interference with other wireless devices in your
neighborhood or the wireless clients do not support channel bonding.
Channel
Selection
Select the wireless channel which this radio profile should use.
It is recommended that you choose the channel least in use by other APs in the region
where this profile will be implemented. This will reduce the amount of interference between
wireless clients and the AP to which this profile is assigned.
Select
DCS
to have the AP automatically select the radio channel upon which it
broadcasts by scanning the area around it and determining what channels are currently
being used by other devices.
Note: If you change the country code later,
Channel Selection
is set to
Manual
automatically.
Select
Manual
and specify the channels the AP uses.
Enable DCS
Client Aware
This field is available when you set
Channel Selection
to
DCS
.
Select this to have the AP wait until all connected clients have disconnected before
switching channels.
If you disable this then the AP switches channels immediately regardless of any client
connections. In this instance, clients that are connected to the AP when it switches
channels are dropped.
