ProSAFE Wireless Controller
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:
- 802.11b.
- 802.11bg.
- 802.11ng. This is the default setting.
• 802.11a/na/ac mode:
- 802.11a.
- 802.11na.
- 802.1na/ac. This is the default setting.
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 By default, the transmit data rate of the WiFi network is set to Best. You
cannot manually change the transmit data rate.
Note: For 802.11na and 802.11ac devices, the page shows separate
data rates with the default setting Best.
Channel Width
(802.11ng and 802.11na/ac only)
From the menu, select the channel width:
• 20 MHz Static. This is the default setting if the selection from the
Wireless Mode menu is 802.11ng.
• 20/40 MHz Dynamic.
• 20/40/80 MHz Dynamic. This is the default setting if the selection
from the Wireless Mode menu is 802.1na/ac. This setting is an
option for 802.11na/ac devices only and does not apply to 802.11ng
devices.
A wider channel improves the performance, but some legacy devices
can operate only with a 20 MHz channel width.
Guard Interval
(802.11ng and 802.11na/ac 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 must send an RTS threshold packet to the receiving station, and
must wait for the receiving station to return a Clear to Send (CTS)
packet before sending the actual packet data.
Beacon Interval (100-1000) Enter the time interval for each beacon transmission that allows the
access point to synchronize the WiFi network.
