We got a call from Cisco after our earlier post about bad security advice: Chris Bollinger, the Cisco exec quoted in the story, maintains that the reporter misunderstood his comments. Instead of recommending that certain organizations ignore 802.11i, he suggested that some types of hardware used in some environments aren't capable of being upgraded to 802.11i so users will have to make due with WPA. For example, some retail stores and warehouses use purpose-built devices that may use Wi-Fi. Such devices may not be upgradeable to 802.11i.
