Wireless LAN Access Point Configuration113.2.2 Wireless SettingThis 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-peercommunication. 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-Pointmode”.

How to manually find your PC’ s IP and MAC Address?1) In Windows, open the Command Prompt program2) Type Ipconfig /all and EnteryYour PC’ s IP address is the one entitled IP addressyYour PC’ s MAC Address is the one entitled Physical Address2. 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 mobileworkers. More than one BSS can be configured as an Extended Service Set (ESS). Users within an ESS could roam freely between BSSs while maintaining acontinuous 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 withDirect Sequence Spread Spectrum technology, it has the inherent scramblingsecurity feature. On the software side, the WLAN series offers the encryptionfunction (WEP) to enhance security and access control.
Troubleshooting417. 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 themanufacturer to any Ethernet networking device, such as a network adapter, thatallows 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.
