When disabled, you will not be able to gain access to your Wireless LAN through this Access Point. If you do not enter the name correctly, you will not be able to connect to your wireless network. The field accepts any alphanumeric string upto a maximum of 32 characters. This option allows your network administrator to identify wireless clients. In Client Bridge mode, Access Points are commonly named after their user or location (if fixed). Encryption When setting up wireless networks, it is important to remember that with encryption disabled, anyone with a Wireless PC can eavesdrop on your network. The Access Point supports two types of encryption: WPA -- Wi-FI Protected Access (WPA) is a 256 bit encryption method with keys that change over time. WEP -- Wireless Equivalent Privacy (WEP) is a 64 bit or 128 bit encryption method with user configurable fixed keys. Wireless Settings 61 WPA provides a higher level of security, provided by its longer key and dynamic changes made to the key over time. 3Com recommends that you use WPA if supported by your wireless network. The Access Point can only use one type of encryption to access the wireless network. If you enable WEP, the options for WPA will not be available. Figure 42 Encryption Keys Screen To set up WPA encryption on your Access Point: 1 In the WPA Encryption Type drop-down box select one of the Enabled options: Select Enabled - Manual Pre-shared key if you have been supplied a set of hexadecimal digits Select Enabled - Pre-shared Passphrase if you have been suppled with a passphrase For a pre-shared key, enter a pair of hexadecimal digits in each of the 32 Key fields, as supplied by your network administrator.
