Done.

 Out of interest, if you revert to 2.6.32 do you find your CMOS has been
 reset so that the wireless is permanently off?  That happens to me
 intermittently.

How do I check if there was a CMOS reset? I just see that once I did a
suspend to disk, ifconfig eth0 up / iwlist eth0 scan does not work with
the same error codes as yours.

Did you tried to bisect it? I did not have time to do it yesterday but I
might tonight.

 State your hardware when doing so (what is it?).

I mentioned it @ lkml, it's an S12 netbook as well.

Thanks.

Re: No probe response from AP address after 500ms, disconnecting.

2010-03-17 Thread Miklos Vajna
Hi,

I recently upgraded to 2.6.33, then 2.6.34-rc1, but both have the same
bugs:

1) The earlier mentioned problem is still there, the b43 driver
disconnects if no WPA is used by the AP.

(This is not an issue with the binary broadcom 'wl' driver.)

2) The wireless card seems not to be functional after suspend to disk:

# iwlist eth0 scan
eth0  Failed to read scan data : Invalid argument

And this is with b43 and wl, 2.6.33 and 2.6.34-rc1. If I downgrade to
2.6.32, both work after hibernation.

Is this a known issue? Also, is there a bugtracker where I should report
these errors? Or should I simply use http://bugzilla.kernel.org?

Thanks!

 Yes, otherwise I don't think wpa_supplicant will do anything.

 It could help to run it in foreground - you should see disconnect and
 reauth then.

OK, when I add this, wpa_supplicant authenticates with the wpa ap on
startup. That's fine, but when I do an iwconfig eth0 essid linksys,
the wpa_supplicant stdout is:

 That's right. You can try wireless-testing as well, currently it
 contains same LP-PHY support level as 33-rc4.

How do I see what's improved?

I just upgraded, and the only thing I could think of is to try iwconfig
eth0 power off, but that's still not supported:

# iwconfig eth0 power off
Error for wireless request Set Power Management (8B2C) :
SET failed on device eth0 ; Operation not supported.
# uname -r

Thanks.

I just tried what happens when the wpa ap is not available, just the
linksys one. It still can't associate, but at least the MAC of the
linksys shows up in the wpa_supplicant output:

CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys
CTRL-EVENT-SCAN-RESULTS

So it's like: it's avilable for about 5 secs, then it goes down for 2,
and this loops forever. :/

Again, this is with 2.6.33-rc4. Now my hope is that wireless-testing has
some changes which are not in 2.6.33-rc4 and that solves this issue, but
I'll wait for your experience first. :)

Thanks,

 It did not help. I merged

 into my kernel, and have posted a message about it to the ath9k list.

:(

OK, for now I think I'll just live with the binary driver
(http://www.broadcom.com/docs/linux_sta/hybrid-portsrc-x86_64-v5.10.91.9.3.tar.gz),
I hate to use external modules, but that one at least works fine for me.

No probe response from AP address after 500ms, disconnecting.

2010-01-14 Thread Miklos Vajna
Hi,

I tried asking on #bcm-users, then found the wiki where it's suggested
to report to this list, so I'm doing so. Sorry for the noise on IRC.

A description of the problem at hand:

My card works fine when I use it with WPA, however when I try to use it
without any encryption (actually the provider uses MAC-based filtering,
but that's not important), then after the iwconfig eth0 essid essid,
iwconfig shows the MAC of the AP, and after about 5 secs iwconfig
says it's Not-Associated. If I run iwconfig eth0 essid again, then
it's usable again for ~5 secs and so on. When the AP goes unassociated,
I see this in dmesg:

No probe response from AP 00:12:17:d3:87:f5 after 500ms, disconnecting.

When it happens:

It happens only in case not using encryption. An other laptop with
ipw2200 driver works fine, so I guess this will be a b43 or firmware
problem. The same card works under Windows XP as well, so I guess it's
not a hardware problem.

How to reproduce:

Run iwconfig eth0 essid essid, wait ~5 secs and run iwconfig
again. Result: it's unassociated. Expected: to show the MAC of the AP,
etc.

 improvements (part of calibration done), and 2.6.34 will (if I have
 time to do it) have full calibration support.

What does calibration support mean?

By performance problem I mean that after iwconfig eth0 essid it's
working for ~5sec, and then it's down till the next iwconfig eth0
essid, so it's basically unusable. :/


By 2.6.33, you mean that I should give 2.6.33-rc4 a try?
