Power Save Mode
:
•
CAM (Constantly Awake Mode)
: When this mode is selected, the
power supply will be normally provided even when there is no
throughput. (Default power save mode is CAM.)
•
PSM (Power Saving Mode)
: When this mode is selected, this device
will stay in power saving mode even when there is high volume of
throughput.
RTS Threshold
: Users can adjust the RTS threshold number by sliding
the bar or key in the value directly. (The default value is 2347.) RTS/CTS
Threshold is a mechanism implemented to prevent the
“
Hidden Node
”
problem. If the
“
Hidden Node
”
problem is an issue, users have to specify
the packet size.
The RTS/CTS mechanism will be activated if the data size
exceeds the values that have been set.
This value should remain at its default setting of 2347. Should users
encounter inconsistent data flow, only minor modifications of this value
are recommended.
Fragment Threshold
: Users can adjust the Fragment threshold number
by sliding the bar or key in the value directly. (The default value is 2346.)
The mechanism of Fragmentation Threshold is used to improve the
efficiency when high traffic flows along in the wireless network. If the
Wireless LAN Module often transmits large files in wireless network,
users can enter new Fragment Threshold value to split the packet. The
value can be set from 256 to 2346.
Authentication and Security tab:
Authentication Type
: There are several types of authentication modes
including
Open, Shared, Leap, WPA, WPA-PSK, WPA2
and
WPA2-PSK
.
•
Open
: If the access point or wireless router is using "
Open
”
authentication, then the Wireless LAN Module will need to be set to
the same authentication type.
•
Shared
: Shared key
is when both the sender and the recipient share a
secret key.
•
LEAP:
Light Extensible Authentication Protocol. It is an EAP
authentication type used primarily in Cisco Aironet WLANs. It
encrypts data transmissions using dynamically generated WEP keys,
and supports mutual authentication (only with CCX mode enabled.)
•
WPA/ WPA-PSK/ WPA2/ WPA2-PSK:
WPA or WPA-PSK
authentications offer two encryption methods, TKIP and AES. For
WPA-PSK, select the type of algorithm TKIP or AES and then enter a
WPA Shared Key of 8-64 characters in the WPA Pre-shared Key
field.
Encryption Type
: For
Open
and
Shared
authentication mode, the
selection of encryption type are
None
and
WEP
. For
WPA, WPA2,
