Wireless access point scanning

I've followed the instructions on this webpage for doing wireless access
point scanning with Nessus:

http://www.tenablesecurity.com/images/pdfs/wap-id-nessus.pdf

but didn't get any results, even though I knew of at least one WAP in the
netblocks I was scanning. So I narrowed the scan down to just the IPs of a
couple of WAPs and tried again.

I get port scan results showing port 23, 80 and 22 are open. But even though
the WAP plugin item is enabled, nothing comes up identifying the WAP. And
this is a Cisco Aironet so it should definitely be identified.

There's no firewall between the scanner and the WAP. I'm using Nessus v2.2.4
with the NessusWX GUI v1.4.5
