Fedora8 - Intel 4965agn card does not work correctly

[Kiran Shastri]

Hi all,
  I installed fedora-8 onto Dell Vostro 1400. We are trying to use the intel 4965agn card on this laptop in ad-hoc mode. 
  1)The iwpriv command does not allow me to set the modulation scheme to 802.11a,b,g ( returns "mode" command not found).If I try "iwpriv wlan0" I only see that the commands param and get param are implemented. Here are the commands I ran:
   iwconfig essid "potato" mode ad-hoc
   ifconfig wlan0 addr 192.168.10.5
   ifconfig wlan0 down
   ifconifg wlan0 up
  After I set the address of the card to 192.168.10.5 and try to ping it from another machine in the same ad-hoc network , it does not work.It looks like this card is not answering the ARP queries being sent out in the ad-hoc network.  Ping works if I try to ping the other direction first and
 then ping from the other machine to this machine.
  2) I set 
  /proc/sys/net/ipv4/conf/wlan0/forwarding =1
   /proc/sys/net/ipv4/conf/wlan0/accept_source_routes =1 .
  But it fails to forward any packet routed through it.
   
  Does anybody have an idea of how to get the card to behave properly?.
   
  Thanks,
  Kiran
