Setting Description
Wireless Mode The selections that are available depend on the selected radio mode.
From the menu select the wireless mode:
• 802.11b/bg/ng mode:
- 1
1ng. This is the default setting.
- 11bg.
- 11b.
•
802.11a/na mode:
- 1
1na. This is the default setting.
- 11a.
Note:
If you select 802.11bg or 802.11b mode, both 802.11n- and
802.11g-compliant devices can connect to the access points. However,
if you select 802.11ng mode, 802.11b-compliant devices cannot
connect.
Data Rate From the menu, select the available transmit data rates of the wireless
network.
Channel Width
(802.11n only)
From the menu, select the channel width:
• 20 MHz Static.
• 20/40 MHz Dynamic. This
is
the default setting.
A wider channel improves the performance, but some legacy devices
can operate only with a 20 MHz channel width.
Guard Interval
(802.11n only)
From the menu, select a value that protects transmissions from
interference.
A shorter guard interval improves performance, but some legacy
devices can operate only with a long guard interval.
RTS Threshold (0-2347) Enter the size of the Request to Send (RTS) threshold packet.
The RTS threshold is related to the transmission mechanism
(CSMA/CA or CSMA/CD) for the packets. If the packet size is equal to
or less than this threshold, the data frame is transmitted immediately; if
the packet size is larger than the specified value, the transmitting
station needs to send an R
TS threshold packet to the receiving station,
and then should wait for the receiving station to return a Clear to Send
(CTS) packet before sending the actual packet data.
