[Madwifi-users] Can't enable Turbo mode

Discussion:

2004-07-27 21:35:23 UTC

I have madwifi on a Redhat 9 laptop using an Atheros pcmcia card. I am
trying to run the driver in monitor mode feeding Ethereal. This all works
as expected in standard mode. However, I need it to work in Turbo mode on
the 5GHz channels.

I have read the man pages, checked the wiki and done a search of the mailing
list archives. It appears that all I need to do is

iwpriv ath0 turbo 1

However, I get the result:

<mapping sub-ioctl turbo to cmd 0x8BE0-1>
Interface doesn't accept private ioctl...
turbo (8BE0): No such device or address

I am a newbie to Linux. Forgive me if this is some obvious problem.

Thanks, Bob

Well I do know that turbo mode isn't supported yet. So that would
explain why you get that error message when you try to activate it.
Besides that, I didn't even know there were Atheros based cards using
the 5 ghz range. What card are you using?

We are specifically trying to use the turbo channels in the outdoor range,
such as 152. There Atheros PCMCIA card I have supports 11a, b and g. It
says model CB22 on the back.

Perhaps I am confused about turbo support. In the material I found, there
was mention of non-support of turbo, but it seemed to refer to turbo mode in
the b/g band. Other material talked about turbo in the a band with no
mention of non-support. Also, I have been in contact with Greg Chesson and
he made no mention of non-support, though he wasn't sure how to activate it.

Cheers, Bob

Static turbo mode in 11a should work. "Static" meaning no
consultation/negotiation of capabilities are used to enable/configure
use. Your original note looked like you were using an iwpriv built
with an old version of the wireless extensions (or there was a similar
mismatch between iwpriv and driver/kernel). OTOH I haven't tried turbo
mode in probably a year so if it's busted I wouldn't be
surprised--though it would probably be only something in the glue code;
not something fundamental.

The Atheros 5212 supports tri-mode dual-band 802.11a/b/g. I'm using IBM's
5212-based card for 802.11a stuff with MADWIFI.

Thank you, thank you, thank you.

It appears to be iwpriv ath0 mode 1.

For the benefit of the archives, here's some more info. I am attempting to
put the device in monitor mode on a specific channel in turbo mode. The
order of entry seems to be important. I think this is the order that
worked:

iwpriv ath0 mode 1
iwconfig ath0 mode monitor
iwconfig ath0 channel 152
iwpriv ath0 turbo 1

Cheers, Bob

Did you try doing a iwpriv mode 3 first?

I think you need to force the card into 802.11a only mode before you can
set turbo.... However, I'm going from memory, so it might be more 2
rather than 3....

No - turbo mode as implemented is only dual-channel 802.11a. It does
not implement Super-G. It also doesn't implement all the features of
Super-A.

When I last played with this (months ago), I also had some problems
getting turbo to work with a Super-A access point, though I may not have
tried all permutations. Setting the access point to dynamic turbo mode
definitely wouldn't work with madwifi set to turbo.

Hi,

if i try iwpriv ath0 turbo 1, I get following:

<mapping sub-ioctl turbo to cmd 0x8Be0-1>
Interface doesn't accept private ioctl...
Turbo (8BE0): No such device or address

I tried with AR5001x and AR5002x

What does this mean? Which cards are needed to support turbo???
Anyone measured performance already with turbo enabled?

Regards,
Togg

I was getting exactly that message before when I entered "iwpriv ath0 turbo
1". Doing "... mode 1" first made the problem go away. I was root when I
executed these commands. Perhaps that is the problem. Make sure the driver
is not in any mode that conflicts with 11A. You might try "iwconfig ath0
mode Managed", then "iwpriv ath0 mode 1".

Good luck, Bob
