3.2.2 Wireless Setting
This Access Point supports AP, Station, Bridge and WDS modes. “AP Mode”
provides pure access point function. The simplest way to build up a wireless LAN is
to use “AP Mode”. “Station Mode” is used to let a network device with only wired
Ethernet function to have wireless LAN communication capability. It provides both
Ad Hoc and Infrastructure modes for the “Station Mode”. With “Station-Ad Hoc
mode”, it can let your network device join a wireless LAN with peer-to-peer
communication. With “Station-Infrastructure mode”, it can let your network device
join a wireless LAN through an access point. “AP Bridge Mode” provides the
function to bridge more than 2 wired Ethernet networks together by wireless LAN.
You can use two access points with “AP Bridge-Point to Point mode” to bridge two
wired Ethernet networks together. If you want to bridge more than two wired
Ethernet networks together, you have to use enough access points with “AP Bridge-
Point to Multi-Point mode”. An access point with “AP Bridge-Point to Point mode”
or “AP Bridge-Point to Multi-Point mode” can only be used to bridge wired Ethernet
networks together. It can’ t accept connection from other wireless station at the same
time. If you want an access point to bridge wired Ethernet network and provide
connection service for other wireless station at the same time, you have to set the
access point to “AP Bridge-WDS mode”. Simply speaking, “AP Bridge-WDS mode”
function is the combination of “AP mode” and “AP Bridge-Point to Multi-Point
mode”.

yYour PC’ s IP address is the one entitled IP address
yYour PC’ s MAC Address is the one entitled Physical Address
2. What is Ad-hoc?
An Ad-hoc wireless LAN is a group of computers, each with a WLAN adapter,
connected as an independent wireless LAN.
3. What is Infrastructure?
An integrated wireless and wired LAN is called an Infrastructure configuration.
4. What is BSS ID?
A group of wireless stations and an Access Point compose a Basic Service Set
(BSS). Computers in a BSS must be configured with the same BSSID.
5. What is ESSID?
An Infrastructure configuration could also support roaming capability for mobile
workers. More than one BSS can be configured as an Extended Service Set (ESS).
Users within an ESS could roam freely between BSSs while maintaining a
continuous connection to the wireless network stations and the Wireless LAN
Access Points.
6. Can data be intercepted while transmitting through the air?
WLAN features two-fold protection in security. On the hardware side, as with
Direct Sequence Spread Spectrum technology, it has the inherent scrambling
security feature. On the software side, the WLAN series offers the encryption
function (WEP) to enhance security and access control.
Troubleshooting

7. What is WEP?
WEP stands for Wired Equivalent Privacy, a data privacy mechanism based on a
64(40)-bit shared key algorithm.
8. What is a MAC Address?
The Media Access Control (MAC) address is a unique number assigned by the
manufacturer to any Ethernet networking device, such as a network adapter, that
allows the network to identify it at the hardware level. For all practical purposes,
this number is usually permanent. Unlike IP addresses, which can change every
time a computer logs on to the network, the MAC address of a device stays the
same, making it a valuable identifier for the network.
