how to enable 11N wireless?

[jack craig]

Hi Folks,

my netbook has:

Network controller: Intel Corporation PRO/Wireless 4965 AG (rev 61)
Ethernet controller: Attansic Technology Corp. Atheros AR8121/AR8113/AR8114 PCI-E Ethernet Controller (rev b0)

I know the 4965 supports both G & N protocols. only G is being used; how do i enable N ?
do i need to kick the controller? on moblin, it said AGN in the banner!

Thx, jackc...
