How do I find out what type of secu rity my network is using?
You must know the WEP key or WPA passphrase and the type of sec urity (WEP, WPA, or WPA2) used on t he wireless
network. To obtain this in formation, see the document ation that came with your wireless access point (w ireless
router), see the Web page associated with t he wireless access point, or consult your system support person.
Note: The WEP key or WPA passphrase is not the same as the password for the wireless access point. The password
allows you to access the wireless access point settings. The WEP key or WPA passphrase allows printers and computers
to join your wireless networ k.
