Fwd: Trying to get IEEE80211n (in hostap) running for ATH9280

[Georg Bege]

Hi guys,

just wanted to tell that I got it up and running.
Rather than trying some commands myself, I just chose an n-compatible
channel (channel 40) from the list and put it into hostapd.conf

hostapd.conf managed to configure the card into the correct mode :-)

However for informative purposes, I'd still like to know what the
difference is and why in this case hostapd.conf is mandatory?
(I mean I know it is for WPA, but why did the kernel refuse the manual
commands?).

regards,
Georg

Hello everyone,

Im one of the sad people not getting IEEE80211n to run (in hostap!).
Im having an (should be) supported AR9280 chip using an pcMachines APU2
device.

----

At the moment, the machine is running an 11.0-RELEASE (pretty vanilla,
except a couple of installed pkg's)
I just got my hands on it a couple of days ago, right now Im using the
well-working 11g mode:

------------------------ snip ------------------------------

------------------------ snip ------------------------------

The wlan0 device is part of an bridge, because I need it working that
way (not sure if that matters).

I get proper supported channels with 'ifconfig wlan0 list channels':

------------------------ snip ------------------------------
root at orion:~ # ifconfig wlan0 list channels

Channel  13 : 2472  MHz 11g ht       Channel 128 : 5640* MHz 11a ht
Channel  36 : 5180  MHz 11a ht       Channel 132 : 5660* MHz 11a ht
Channel  40 : 5200  MHz 11a ht       Channel 136 : 5680* MHz 11a ht
Channel  44 : 5220  MHz 11a ht       Channel 140 : 5700* MHz 11a ht
------------------------ snip ------------------------------

I tried several commands such as 'ifconfig wlan0 mode 11n (or 11ng)
channel 6:ht/40 - or just channel 40 etc.

All my attempts result in: ifconfig: SIOCS80211: Invalid argument

Not sure what's the proper way to setup 11n(g) - there are multiple
entries on multiple forums, people basically tinkering around until they
may get it working (or not?).

Any hints where I can read up how this works or an page which tells the
definitive commands which are necessary is highly appreciated.
As far as I understood 11.0-RELEASE should be recent enough (?), however
I can of course upgrade the box to 11.0-STABLE as well.
Just not sure if its worth the buzz...

best regards,
Georg
