Authentication
Most enterprise wireless networks make use of some form of secure
authentication. This typically means 802.1x or VPN, although other choices
are possible. The troubleshooting process is different depending on which
authentication scheme is in use.
802.1x
Authentication using 802.1x may be accomplished in combination with
dynamic WEP key exchange, WPA with TKIP, or 802.11i with AES. The
troubleshooting process for the authentication portion is identical in all cases.
