From what I found last Mar 2009 or so, rt2800usb didn't support 802.11n.
It looks like rt2x00 has been updated to support 802.11n but couldn't find whether rt2800usb has been intregrated into rt2x00.
I'm using Dlink DWA 160 which uses ralink 2870 chipset, using it in monitor mode
and wanted to find out if the rt2800usb driver would support 802.11n and if so what version of this driver (or another driver) I would need to use? I'm on Debian lenny-backports which believe is 2.6.32, and running on 686.
Thanks for help / links.
