Setting 'n' or 'a' Mode, and WPA2?

Setting 'n' or 'a' Mode, and WPA2?

[Delphi Real Estate]

I want to switch to 802.11a for streaming media, so I'm not polluting everyone else's bandwidth.  Does anyone know how I set the 4965 to 'a' or 'n' only?  Is there any way to set it to dual-band for the new routers which send normal traffic on 'g' and stream on 'a'?  How do I set it to WPA2 only?  

IOW, how do I control this card?  Instructions are nowhere to be found.

Currently my /etc/network/interfaces file is set thus and works (Network Manager is uninstalled and I don't trust it):
iface wlan0 inet static
pre-up /sbin/iwconfig wlan0 txpower 5
pre-up ip link set wlan0 up
address 192.168.1.1
netmask 255.255.255.0
gateway 192.168.1.5
wireless-essid Hex
wpa-scan-ssid 0
wpa-ap-scan 1
wpa-ssid Hex
wpa-psk Freeasinfreedom

Wow, surely this is not unknown by some of you guys.  Isn't anyone using 'a' mode or 5GHz 'n' mode?  WPA2?

Will you please advise?

Umm, no. A single card can only be on one band at a time.

OK, so you're saying that only the 'n' Draft2 routers can do that?  That this firmware for the 4965AGN does not have Draft2 features?

Does it have Draft1 features?

How do you set only 5GHz 'n' mode?  WPA2?

No. An access point can operate on both bands at the same time, but
not a wireless client - a client must choose _one_ band from the
several ones offered by the AP and operate on that band.

OK, that's fine.
=20
So does the driver/firmware firmware for the 4965AGN have Draft2 featur=
es?

Does it have Draft1 features?

How do you set only 5GHz 'n' mode?  WPA2?

Of course, why didn't I think of that.  That's like saying, "To make pancakes, make pancakes."

My goal is to set /etc/network/interfaces to specifically configure the 4965AGN card for 5GHz 'n' mode *only* and WPA2.  I can't find any documentation on setting 'n' mode, nor WPA2 specifically.

I'd like no broadcast of SSID, which I have working now on 'g' but don't know whether it's possible in 5GHz 'n'.  And I'd like cloaked traffic and as little handshake traffic as possible, although much of this seems impossible now with as little as is known about configuration.

I'd just be happy with 5GHz 'n' mode and WPA2.  Isn't there any documentation?

You are not reading this correctly. The mode depends on access point
setting, there is nothing special to configure.

For WPA2 you need wpa_supplicant so read it's manual for configuration.

Please note for 2.6.27 and above aggregation is broken in iwlagn
(4965) and this is what you need for good streaming. It shell be fixed
in near future hopefully.

Most access points can't even do that.
