Introduction: 802.11g/Draft 802.11n WLAN Module, SDGOB-0991 User's Guide Before you begin Things you should know SDGOB-0991 network Before you begin Obtain the following information from your network administrator (if you are a home user, obtain this information from the person that installed your wireless access point):
l Network names (SSID) of the specific wireless networks that you want to connect to. l WEP (Wired Equivalent Privacy) key information (if any) for the networks you want to connect to. l For Microsoft Windows networking, your customer name and workgroup name. l For your network account, your user name and password. l Your IP address (if not using a DHCP server) Things you should know When you start your computer, your SDGOB-0991 card detects certain wireless networks that are within range. Before you can connect to these and other wireless networks, you must configure a profile for each network using the information you obtained from your network administrator. WEP is a security protocol for wireless local area networks (defined in the IEEE 802.11g standard) that encrypts data sent over radio waves. The use of the WEP key is optional and can be enabled or disabled. If the network you are connecting to has enabled WEP, you must also enable WEP in the network profile and set the WEP key to match the WEP key used by the network. Otherwise, you cannot connect to the network. Broadcom SDGOB-0991 network The SDGOB-0991 card solution allows you to make a wireless connection to a network, as illustrated below.
