WDS
A Wireless Distribution System (WDS) is a system enabling the wireless interconnection of
access points in an IEEE 802.11 network. It allows a wireless network to be expanded using
multiple access points without the traditional requirement for a wired backbone to link them.
The notable advantage of WDS over other solutions is it preserves the MAC addresses of client
frames across links between access points.
WDS may also be considered a repeater mode because it appears to bridge and accept
wireless clients at the same time (unlike traditional bridging).
However, with this method, throughput is halved for all clients connected wirelessly.
Wireless Security

Encryption
Chooses between No Encryption (open) and the following encryptions: WPA-PSK, WPA2-
PSK, WPAPSK/ WPA2-PSK Mixed Mode, WPA-EAP, and WPA2-EAP.
WPA or WPA2 with PSK
Wifi protected access (WPA) is a stronger encryption than WEP.
Furthermore, WPA2 was developed to strengthen the security of WPA and is stronger than WPA
and WEP.
For WPA-PSK, WPA2-PSK, WPA-PSK/WPA2-PSK Mixed Mode encryptions, we have the following
options.
Cipher
Can be set to Auto, CCMP (AES), or TKIP and CCMP (AES). The Temporal Key Integrity
Protocol (TKIP) was developed as a temporary replacement for WEP. The Counter Mode
Cipher Block Chaining Message Authentication Code Protocol (CCMP) is based on the
Advanced Encryption Standard (AES) and is the most secure protocol.
Key
The pre-shared key (PSK) is the password for the wireless network. This may consist of 8
to 63 ASCII characters.
