Authentication Type
To provide a certain level of security, the IEEE 802.11 standard has
defined two types of authentication methods, Open System and Shared
Key. With Open System authentication, a wireless PC can join any
network and receive any messages that are not encrypted. With Shared
Key authentication, only those PCs that possess the correct
authentication key can join the network. By default, IEEE 802.11
wireless devices operate in an Open System network.
Wired Equivalent Privacy (WEP) data encryption is used when the
wireless devices are configured to operate in Shared Key authentication
mode.
If the Access Point is using "
Open Authentication
”, then the wireless
adapter will need to be set to the same authentication mode.
Shared Authentication
is used when both the sender and the recipient
share a secret key.
Select
Auto
for the network adapter to select the Authentication mode
automatically depending on the Access Point Authentication mode.
Fragment Threshold
Fragmentation mechanism is used for improving the efficiency when
high traffic flows along in the wireless network. If your 802.11g
Wireless LAN PC Card often transmit large files in wireless network,
you can enter new Fragment Threshold value to split the packet. The
value can be set from 256 to 2346. The default value is
2346
