„
Turbo (40MHz ): Each channel will use 40MHz, double the normal size, to increase the
performance by channel binding. This option is not allowed in countries inside EU
„
Normal (20MHz) : This is the default channel width specified by IEEE 802.11a
specification
„
Half (10MHz) : Using this option would double the available channels for deployment in
congested areas. However, the performance will also drop by half when using this
option.
„
Quarter (5MHz) : Using this option will increase the available channels by 4 times. It is
a good choice for deployment in very congested areas. However, the performance will
also drop greatly when using this option.
4.2.9 Security Settings
Operation Mode -> Setup -> Security Settings
Security settings allow you to use encryption to secure your data from eavesdropping.
You can select different security policy to provide association authentication and/or data
encryption. The A.DUO features various security policies including WEP, 802.1x, WPA,
WPA-PSK, WPA2, WPA2-PSK, WPA-Auto, and WPA-PSK-Auto. Please note not all
security policies are available in all operation modes. For example, only WEP is available
currently in WDS Bridge mode and Client Ad hoc mode. All wireless devices on the same
network must use the same security policy. We recommend using WPA-PSK or
WPA2-PSK whenever possible. For WDS Bridge and Client Ad hoc mode, we recommend
using WEP-152 encryption.
WEP : WEP Encryption is the oldest and most available encryption method. However, it is
also the least secure. Due to the limitation of the chipset, only WEP encryption is available
for WDS Bridge Pure MAC mode and Client Ad-hoc mode.
