inconsistent data flow, only minor modifications are recommended. If a
network packet is smaller than the preset “RTS threshold” size, th
e RTS/CTS
mechanism will not be enabled. The ADSL modem (or AP) 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.
Beacon
Interval
The Beacon Interval value indicates the frequency interval of the beacon.
Enter a value between 20 and 1024. A beacon is a packet broadcast by the
ADSL modem (or AP) to synchronize the wireless network. The default is
100.
Data Rate
The rate of data transmission should be set depending on the speed of your
wireless network. You should select from a range of transmission speeds, or
you can select
Auto
to have the ADSL modem (or AP) automatically use the
fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback
will negotiate the best possible connection speed between the AP and a
wireless client. The default setting is
Auto
.
Preamble
Type
The Preamble Type defines the length of the CRC (Cyclic Redundancy Check)
block for communication between the AP and mobile wireless stations. Make
sure to select the appropriate preamble type. Note that high network traffic
areas should use the
short preamble
type. CRC is a common technique for
detecting data transmission errors.
Broadcast
SSID
If this option is enabled, the device will automatically transmit their network
name (SSID) into open air at regular interval. This feature is intended to
allow clients to dynamically discover and roam between WLANs; if this
option is disabled, the device will hide its SSID. When this is done, the station
cannot directly discover its WLAN and MUST be configure with the SSID. Note
that in a home Wi-Fi network, roaming is largely unnecessary and the SSID
broadcast feature serves no useful purpose. You should disable this feature to
improve the security of your WLAN.
Relay Blocking When
Relay Blocking
is enabled, wireless clients will not be able to directly
access other wireless clients.
Ethernet to
Wireless
Blocking
When enabled, traffic between Ethernet and wireless interfaces are not
allowed.
WiFi Muticast
to Unicast
Router receives Multicast streams from the network backbone, converts
them to Unicast format, and routes them to the end-users over the last mile
infrastructure (e.g. DSL, Ethernet, WiFi).
