I do not use any external / 3rd party Wi-Fi managers, nor do I use Wireless
Zero Config (the service is stopped). My IM driver is responsible for
sending the proper OID sequence to switch access points. Whether the D-Link
DWL-122 is better or worse than the Cisco Aironet is of no effect to me, as
long as they work sufficiently for me to do my testing (we have plenty of
other WiFi cards, anyway - I was just speaking from past experience).
