On Ubuntu, I managed to get Belkin N1 Wireless Desktop card working at 54 mbs using the atheros net5416 drivers, however, I can't seem to get it connected at 802.11n speeds. (ndiswrapper 1.33, utils 1.9)

I set my network to 802.11n only at 5 GHz, and the card doesn't see it.
I set it to 802.11n at 2.4 GHz, and it sees it and connects, but gets speeds approximate to 802.11g (although iwconfig does say Bit Rate: 300 Mb/s) I did have to set "iwpriv wlan0 network_type a". I tried to set network_type to 'n' but it doesn't recognize it.

So, a few questions:
a) Is there a way to get the card to see the 5 GHz range?
b) Is there a way to get the system to believe it's 802.11n?
c) Anything other suggestions to get decent speed?
