Field Name Description
Multicast rate Select the multicast transmission rate for the network according to the speed of your wireless network. Select
from a range of transmission speeds or select Auto to have the gateway automatically use the fastest possible
data rate and enable the
speed between the gateway and a wireless client.
Options are Auto and 6 - 54 Mbps. The default value is Auto.
Basic Rate Select the basic transmission rate ability for the AP. Options are Default, All, and 1 & 2 Mbps and 1 & 2 & 5.5
& 6 & 11& 12 & 24 Mbps. The default is Default.
Fragmentation Enter the size at which packets will be fragmented into smaller units. The primary consideration for this
Threshold setting is the size/capability of the circuit. Options are 256 - 2346 bytes. The default is 2346 bytes.
Note: A high packet error rate is an indication that a slightly increased fragmentation threshold is needed.
When possible, the default value of 2346 bytes should be maintained. Poor throughput is a likely result of
setting this threshold too low.
RTS Threshold The gateway sends Request to Send (RTS) frames to a particular receiving station and negotiates the sending
of a data frame. After receiving an RTS, the wireless station responds with a Clear to Send (CTS) frame to
acknowledge the right to begin transmission.
If a packet is smaller than this setting, the WLAN client hardware does not invoke its RTS/CTS mechanism.
Options are 256 - 2347 bytes.
The default value of 2347 (disabled) should be left in place unless you encounter inconsistent data flow. In
that case, make small reductions to this value until the issue is resolved.
DTIM Interval Enter the Delivery Traffic Indication Message (DTIM or Beacon rate) countdown variable used to indicate when
the next window is available to client devices for listening to buffered broadcast and multicast messages.
Options are 1 - 255. The default is 1.
Beacon Interval Beacon information packets are sent from a connected device to all other devices where it announces its
availability and readiness. A beacon interval is the period of time (sent with the beacon) that the device waits
before sending the beacon again.
Enter the time interval (in milliseconds) between beacon transmissions. Options are 1 - 65535 ms. The default
is 100 ms, which is recommended.
Global Max Clients Enter the maximum number of clients that can assess this wireless network at one time. The maximum for
5GHz is 80; the maximum for 2.4GHz is 128. The default is the maximum number for each band.
Note: You must change this field before you can change the
Xpress™ Select whether to enable Xpress Technology, a special accelerating technology for IEEE802.11g. Options are
Technology Enable and Disable. The default is Enable.
Regulatory Mode (Available for 5 GHz band only) Select whether to enable support for 802.11 regulations. Options are
Disabled, 802.11h, and 802.11d. The default is 802.11h.
Pre-Network Radar (Available for 5 GHz band only) The radar check parameter setting for traffic trying to access your gateway
Check from outside the network. The displayed value is -1.
In-Network Radar (Available for 5 GHz band only) The radar check setting for traffic trying to access your gateway from inside
Check your network. The displayed value is -1.
TPC Mitigation(db) Select the TPC mitigation value in db. Options are 0(off), 2, 3, and 4. The default is 0(off).
