Dlink DWL-G650 Madwifi and my confusion

[Antonio Montagnani]

I bought a Dlink wireless card (DWL-G650) that is fully supported by madwifi.
I installed required rpm's from livna.
I am somewhat confused by this points:

1) ath modules are loaded
lsmod:

I do not find any wireless device in Network Config Tool but an eth0
(my wired Ethernet card) and a wifi0 (another Ethernet card) that
seems connected to my wireless card (shown as Atheros AR5212).

If I digit iwconfig:

lo        no wireless extensions.

eth0      no wireless extensions.

wifi0     no wireless extensions.

ath0      IEEE 802.11b  ESSID:""
          Mode:Managed  Channel:0  Access Point: Not-Associated
          Bit Rate:0 kb/s   Tx-Power:18 dBm   Sensitivity=0/3
          Retry:off   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=0/94  Signal level=-95 dBm  Noise level=-95 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

sit0      no wireless extensions.

and my modprobe.conf is:

alias eth0 natsemi
install snd-intel8x0 /sbin/modprobe --ignore-install snd-intel8x0 &&
/usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-intel8x0 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ;
}; /sbin/modprobe -r --ignore-remove snd-intel8x0
alias usb-controller ehci-hcd
alias usb-controller1 uhci-hcd
alias ieee1394-controller ohci1394
alias wifi0 ath_pci

Should I see a ath0 in my Network Configuration Tool???
I googled a lot (all this morning) but no easy and clear document how
to easy install this card!!!

Any help??
