I am trying to connect to a wireless network which uses WPA2 Enterprise for wireless security using NetworkManager. But I am not able to connect to it.

The BS is not hidden. My NetworkManager shows me the wireless network and its strength. But it does not connect to it after I enter the Identity and Password.

I have two wireless network cards. 'lspci' output shows:
(Internal card) Intel PRO/Wireless 2200BG Network Connection (rev 05) --- uses ipw2200
(plugin card) Atheros Communication, Inc. AR5212 802.11abg NIC (rev 01) --- uses madwifi drivers

The plug-in card is a Proxim Orinoco Gold 8470-WD model. I am not able to connect to this network with any of these cards in Linux, though am able to connect to the network in windows. So I am guessing that it might either be a NetworkManager issue or a Fedora issue.

I am currently on Fedora Core 7.
How do I debug this problem? Would appreciate any help in this regard.
