Are you sure you're not sniffing broadcast or multicast packets ?
If not, then I promiscous mode should be fine, and I suspect the
issue is on the DHCP server side. Is it some embeded device which acts as
DHCP server ? The access point maybe ? Maybe it won't give more than one
ip per wireless device, independant from the number of MAC addresses sent by
this wireless device ?
Ho, and I guess you don't have MAC adress filtering on the acces point ...
