Alternative DFS Channel
If you have enabled the "DFS" function, on the "Basic" page, specify the alternative
channel here. If you want the access point to search for a free channel itself, use "Auto".
If a primary user was detected both on the main and alternative channel, the access point
automatically searches for a free channel.
If you want to use a fixed channel, select the required channel from the drop-down list.
●
HT Channel Width [MHz]
You can specify the channel bandwidth only with the IEEE 802.11n transmission
standard.
The following settings are possible.
–
20
Channel bandwidth 20 MHz
–
40 up
Channel bandwidth 40 MHz. The configured channel and the neighboring channel
above it are used.
–
40 down
Channel bandwidth 40 MHz. The configured channel and the neighboring channel
below it are used.
Note
Channel bandwidth 40 MHz and frequency band 2.4 GHz
If the access point detects another access point on the configured channel or on
neighboring channels, the access point changes the channel bandwidth from 40 MHz
to 20 MHz. If you set a "free" channel on the access point, the access point uses the
channel bandwidth 40 MHz.
