Question changed mac address + got dhcp add ! but can't ping


I've changed my mac address from its default in /etc/rc.d/rc.inet1.conf. I connect to an adhoc network and I'm even issued an ip address. But I can't ping the system. WTF? I can even renew the ip address but I still can't ping/share files etc.

Whats going on here? The knemo lights up indicating data is being sent but the ping requests fail?????

Can you run 'ifconfig' and 'route' and post the results?

This is route using default mac

Code:
root@lib09/home/clay> route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.0.0     *               255.255.255.0   U     0      0        0 ath0
localnet        *               255.252.0.0     U     0      0        0 eth0
loopback        *               255.0.0.0       U     0      0        0 lo
default         homeibm.mshome. 0.0.0.0         UG    0      0        0 ath0

And here we have changed the mac.


Code:
root@lib09/home/clay> route

loopback        *               255.0.0.0       U     0      0        0 lo
default         192.168.0.1     0.0.0.0         UG    0      0        0 ath0
root@lib09/home/clay> cat /etc/resolv.conf

search mshome.net
root@lib09/home/clay> ifconfig ath0
ath0      Link encap:Ethernet  HWaddr AB:01:23:45:67:89

          RX bytes:193014 (188.4 Kb)  TX bytes:68963 (67.3 Kb)

Ok I checked madwifi.org and they have some 'new' manuals.
Changed it via wifi0.
Now and I can ping but no real services i.e. smbclient and www access fails.

Anyone encounter this. I know I'm close to the answer.
