Thanks Pavel, appreciate your inputs

To update, I got this working on madwifi 0.9.4 official release/centos 5.0 (2.6.18 kernel version) with some minor tweaks to overcome compile issues
The AP mode worked like a charm with the same DLink card 

I m good with this setup so I will continue with this combination.. thanks once again

Regards
Vivek

You can do that if you want, but I'm not aware of any regressions that
could have caused that.

I think it would be more interesting to upgrade the kernel and try
ath5k (the AP support in ath5k appeared in Linux 2.6.31 if I remenber
correctly).  You can try the latest trunk snapshot of MadWifi with the
existing kernel.

I still think it's more likely to be a configuration problem.  Try
running ping on both sides and see what you have on the air (check both
ICMP requests and replies).  Try sniffing on ath0.  Recheck encryption
settings on both sides.  Get another Linux system and make it associate
to the AP.
