Make sure you have SSID (network name) configured in your Cisco wireless AP.
The Proset software should be able to display the available wireless network as long as the SSID is not hidden.
There is no need to enable ipv6.
I should add that these are thin ap's that get their config from WISM's.
For PROSet Connection Utility to display AP Name, 'Aironet Extensions' must be enabled on the Cisco AP.
On Cisco's 1200 Series AP....there is a Enable/Disable option available for Aironet Extensions on Express Setup page.
