The document How to Subscribe a Wireless-Only Device to Dormnet was retired on November 20 2018.
At that time, the ability to register wireless networks interface was removed from the Host Database as announced here. This was in support of the University's transition of wireless services from puwireless to servicenet announced here.
Wireless network interfaces affiliated with Princeton University customers should use Eduroam wireless service if they can; those which cannot use Eduroam should instead use servicenet wireless service. (Eduroam wireless service does not require registration of wireless network interfaces; servicenet wireless service requires registration of wireless network interfaces using a facility other than the Host Database.)
