[CentOS] Connecting to WiFi private networks

Hi all,

I am using NetworManager and NetworkManagerInfo in my Laptop, to
connect to WiFi networks.

It works great with open DHCP networks, but now i am in a Hotel wich
gave me a login/password to connect to its network, and
NetworkManagerInfo sees the WiFi network as private and opens a dialog
windows but only asking a

passphrase or HEX key, no login / password options.

what can i do? maybe use anoter application rather than NetworkManager?

XP works great in that Hotel. :(

regards,

Guillermo
