DHCP is done after associating, which is the only thing that comes to mind 
that could cause this "reappearance of DNS", since ping goes through ok. How 
are you doing DNS? Is there a local named running or is /etc/resolv.conf 
pointing directly to the nameserver?
Where is that nameserver? On the wired network? Can you ping the nameserver or 
anything else on the wired network when this happens? Is there any change 
in /etc/resolv.conf after reassociation?

Problem with today's modular software: they start with the modules
    and never get to the software part.
