Troubleshooting This chapter provides solutions to problems usually encountered during the installation and operation of the Wireless Converter. 1. How to manually find your PCs IP and MAC Address?

In Windows, open the Command Prompt program 1) 2) Type Ipconfig /all and Enter

Your PCs IP address is the one entitled IP address

Your PCs MAC Address is the one entitled Physical Address 2. What is BSS ID?

A group of wireless stations and an Wireless Converter compose a Basic Service Set (BSS). Computers in a BSS must be configured with the same BSSID. 3. 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 Wireless Converters. 4. 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. 5. What is WEP?

WEP stands for Wired Equivalent Privacy, a data privacy mechanism based on a 64(40)-bit shared key algorithm. 6. What is a MAC Address?

51 Troubleshooting 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. 52 Troubleshooting FEDERAL COMMUNICATIONS COMMISSION This device complies with Part 15 of the FCC Rules.
