However, Linksys officials said they typically move so many wireless products each month that chip-set availability is a problem, so they will also be releasing draft 802.11n products based on chip sets from Atheros and Marvell.

Mike Hurlston, vice president and general manager for Broadcom's Wireless LAN Division, claims that the Intensifi chips will support the 5GHz band, but none...
