Description
Authentication Type
•
Open System:
Open System authentication is not required to be
successful while a client may decline to authenticate with any particular
other client.
•
Shared Key:
Shared Key is only available if the WEP option is
implemented. Shared Key authentication supports authentication of clients
as either a member of those who know a shared secret key or a member of
those who do not. IEEE 802.11 Shared Key authentication accomplishes
this without the need to transmit the secret key in clear. Requiring the use
of the WEP privacy mechanism.
•
Auto:
Auto is the default authentication algorithm. It will change its
authentication type automatically to fulfill client’s requirement.
Fragment Threshold
This value should remain at its default setting of 2346. It specifies the maximum
size for a packet before data is fragmented into multiple packets. If you
experience a high packet error rate, you may slightly increases the “Fragment
Threshold” value within the value range of 256 to 2346. Setting this value too
low may result in poor network performance. Only minor modifications of this
value are recommended.
RTS Threshold
This value should remain at its default setting of 2347. Should you encounter
inconsistent data flow, only minor modifications are recommended. If a network
packet is smaller than the preset “RTS threshold” size, the 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.
