Is your computer sending its hostname along with the DHCP request on the wireless? You can check using Wireshark or any other packet logger (set the capture filter to "port 67 or port 68"). Likely, the computer requesting an IP on the wireless is just not sending that field, or you have some other hardware (like a managed switch with DHCP snooping or DHCP relay) that is modifying the request for some reason and removing the hostname value.
I can't say that this is the case for sure, because most of my network segments have DHCP managed by a Windows Server, and the one that is using the pfSense DHCP currently has only a single device on it (which does not have a hostname), but it is the most likely answer AFAIK. Moshe
