20/40 MHz Co-
Exist (2.4GHz) :
Enable or disable the existence of both 20 MHz and 40 MHz channel
width. Keep it enabled to achieve the maximum operability of wireless
products using different standards in your environment. However, it
might prevent your 802.11ax or 802.11n devices from reaching the
maximum performance.
5 GHz 802.11
Mode:
Select the desired wireless networking standard(s) to use. The
available options are
11A Only
,
Mixed 11A/N
,
Mixed 11AC/N/A,
Mixed11AC/N, Mixed11AC/N/AX
.
5 GHz Channel
Width:
Channel Width is available if you selected
Mixed 11A/N, Mixed
11AC/N/A, Mixed 11AC/N,
and
Mixed 11AC/N/AX.
Select the desired
channel width. The available options are
20 MHz
,
20/40 MHz
, or
20/40/80 MHz
. Using wider channel width can increase bandwidth,
so if you have 802.11ax and 802.11ac devices, choose
20/40/80 MHz
.
However, in a congested environment, the highest channel width
is usually not recommended since it leads to higher probability of
clashing channels. Depending on the selected 5 GHz 802.11 Mode,
some options may be unavailable.

Interval :

data rate by lowering the guard interval to 400 ns.

default is

(recommended).
Preamble Type:

to set it to short and

to set it to long.
