What sort of info would you like?  

Wonky is as wonky does.   Only IPCop gives out DHCP.

Below is a snippet of the /var/messages log (dhcp tags only) from the date it was happening.  At one point, I unplugged the patch cord from the wlan port of the IPCop box and had the client request DHCP.    It then got the correct fixed lan address.
