Hi,
I noticed that all of the new madwifi releases ported to kamikaze with minstrel rate estimator by default don't work correctly. Minstrel always stays at 36M and it cannot be changes by 'iwconfig ath0 rate XX' - the system reboots immedetely (tryed diffrent madwifi releases with diffrent kamikaze revisions on both broadcom and x86 platforms)
Can I change the default rate estimator to sample? I want to use new madwifi on my AP but the minstrel bothers me...
What is the last rev that you tried?
madwifi r2377-20070526, kamikaze r7350
You can change the rate control module in package/madwifi/Makefile
Change "RATE_CONTROL:=minstrel" to "RATE_CONTROL:=sample"
Thanks, I will try this and back with info.
on latest madwifi 01/06/2007 and kamikaze r7433 there is still problem with setting fixed tx rate
I tried both minstrel and sample estimators and always 'iwconfig ath0 rate XX' ands with this:

Kernel panic - not syncing: Fatal exception in interruptso its not a wireless-tools version problem..
you may want to try this 0.9.3.1 madwifi package. I understand nbd is working quite hard to clear this issue.

The problems with kernel panic seems to be gone with new releases (madwifi 2.6.21.1+r2420-20070602, kamikaze r7478) but there are still some issues:
after fixing the AP tx rate to some value the client card reports something else - the rates are hopping like in 'auto tx rate mode".

Marek, did you check the 0.9.3.1 at all?
I will check your madwifi today and back with results.
I tried to compile madwifi from your link.
I deleted all original files and directories in /trunk/package/madwifi folder and extracted your arichve right there.
I also did 'make package/madwifi-clean' and then -compile and I got:

looks like this is a job for the new quilt feature 
edit: btw. kamikaze trunk uses now madwifi r2420-20070602

I know, test results are above...
you may want to try this 0.9.3.1 madwifi package. I understand nbd is working quite hard to clear this issue.
Can you please try again? I just fixed the patch.

I tried this package but it does not work as it looks like someone converted spaces to tabs between 9.2 and 9.3 and two of the patches (100 and 101) fail.
How's the latest version from trunk doing?

I am having problems with the version from the trunk with the kernel locking up.

you can always add the -l option on the patch command on the scripts/patch-kernel.sh until I learn how to produce propper patches !!

The discussion might have continued from here.
