I called tech support, and was told that it was not possible to determine if wireless is enabled and active via LANDesk; however, I figured out a solution and it worked. I created the following query.
"Computer"."Network Adapters"."Network Adapter"."Link Status" = "Connected" AND ("Computer"."Network Adapters"."Network Adapter"."File Description" = "Intel(r) PRO/Wireless LAN Driver" OR ("Computer"."Network Adapters"."Network Adapter"."File Description" = "Intel(r) Wireless LAN Driver"
Tested and applied on LANDesk 8.5, LANDesk 8.6, LANDesk 8.6 SP1
