Why would your client mess with DHCP on roaming? Mine at home never do.
I roam between 3 of them several times a day, a proper handoff on both
sides means i don't even realize it happening, let alone re-associate
with DHCP and all that jazz - it happens at the MAC layer and isn't
visible to the OS unless it asks the current station BSSID and decides
to do something about it. "APs properly configured" comes into play here
