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 Select the wireless channel which this radio profile should use.
Selection
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
Select Manual and specify the channels the AP uses.
DCS Time This field is available when you set Channel Selection to DCS.
Interval
Enter a number of minutes. This regulates how often the AP surveys the other APs
within its broadcast radius. If the channel on which it is currently broadcasting
suddenly comes into use by another AP, the AP will then dynamically select the next
available clean channel or a channel with lower interference.
Enable DCS This field is available when you set Channel Selection to DCS.
Client Aware
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.
Chapter 35 Object
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.
