3.2.2 Wireless Setting
This Access Point supports AP, Station, Bridge, WDS and Universal Repeater 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”. “Universal Repeater Mode” provides the function to act as AP client and AP at the same time. It can use AP client function to connect to a Root AP and use AP function to service all wireless stations within its coverage. All the stations within the coverage of this access point can be bridged to the Root AP. “Universal
Repeater Mode” is very convenient to extend the coverage of your wireless network.

Troubleshooting
Chapter 4 Troubleshooting
This chapter provides solutions to problems usually encountered during the installation and operation of the Access Point.
1. How to manually find your PC’s IP and MAC Address?
1) In Windows, open the Command Prompt program
2) Type Ipconfig /all and Enter y Your PC’s IP address is the one entitled IP address y Your 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,
3. What is Infrastructure?
An integrated wireless and wired LAN is called an Infrastructure configuration. connected as an independent wireless LAN.
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.
