There are 2 types of wireless links as specified by the IEEE 802.11 standard.
y
STA-AP:
This type of wireless link is established between an IEEE
802.11 Station (STA) and an IEEE 802.11 Access Point (AP). An STA
is usually a client computer (PC or PDA) with a WLAN network
interface card (NIC). The AP Client mode is actually an STA.
y
WDS:
This type of wireless link is established between two IEEE
802.11 APs. Wireless packets transmitted along the WDS link comply
with the IEEE 802.11 WDS (Wireless Distribution System) format at
the link layer.
The relationships among the operational modes and the wireless link types
are shown in the following table:
AP/Bridge
AP Client
AP/Bridge
WDS STA-AP

STA-AP
To establish a static bridge link based on WDS, the AP/bridges at both end of
the WDS link must be manually configured with each other’s MAC addresses.
To establish a dynamic bridge link between an AP and an AP Client, both
devices have to be configured with the same SSID and WEP settings. The
AP Client automatically scans for any AP that is using the matched SSID and
establishes a bridge link with the scanned AP.
(Note: Although it’s more convenient to use dynamic bridging, it has a
limitation. The AP Client only can forward TCP/IP packets between its
wireless interface and Ethernet interface and other type of traffic (such as IPX
and AppleTalk) is not forwarded.)
3.4.2 Changing Password
On this page, users can change the user name and password for the right to
modify the configuration of the bridge. The new password must be typed
twice for confirmation.
