Kernel: ath0: stuck beacon; resetting (bmiss count 4)

cmb

It may be possible this is related to one of our mbuf patches that was reverted and deferred to a future version, I really doubt it as it would likely be universal and cause panics but it's possible, try today's snapshot or newer.

Hi!
I have had this for a while also.

Try setting hw.ath.bstuck to 8 in system/advanced/system tunables (add new row).

I also added hw.ath.longcal and value 30.

For me WiFi now works better.

i was surprised to see replies to this thread coz i just stopped getting mails regarding new posts from the forum for some reason.

Looks like the mail queue is backlogged. I'm getting the notifications, they're just extremely slow.

For me changing wifi channel worked a few times already (as I get this error from time to time).

Hmm, weird :P

Here it seemed like I just had to choose the right settings, although I haven't got a clue which setting it might have been that solved it…
(About the issue you created this topic for, not the email problem ;) )

i was planning to post a bounty to start with $100 and mayb more ppl can contribute to it to make wireless hotspot more robust and alos get rid of these stuck beacon if any1 was willing to complete it.

bartgrefte

Which wifi card are you using btw?

xbipin

Compex WLM54G atheros 5414 chipset but it reports as this:
dev.ath.0.%desc: Atheros 5413

bartgrefte

Hmm…

Well, maybe this bug is fixed in a newer version of the ath(4) driver.
I've been told someone is working on it and also adding N support.

Only I don't know where to get the most recent version of this driver and how to update the one that currently comes with pfSense.

same problem here:

kernel: ath0: stuck beacon; resetting (bmiss count 4)

hardware is:

kernel: ath0: <atheros 5212="">mem 0xfd8f0000-0xfd8fffff irq 17 at device 1.0 on pci5
kernel: ath0: [ITHREAD]
kernel: ath0: AR2413 mac 7.9 RF2413 phy 4.5

Version 2.0-BETA5 (i386)
built on Thu Feb 24 17:17:04 EST 2011</atheros>

probably only the devs would know i guess on how and where to get the updated drivers, i would be very much interested in it.

bartgrefte

I asked on the FreeBSD forum, got this:

svn co http://svn.freebsd.org/base/head/sys/dev/ath

But does pfSense have svn? Haven't looked at that yet…

might not work if there where changes in the kernel that are needed by the updated driver.

bartgrefte

Installed svn using```
pkg_add -r subversion

Then I used scp to copy over these from my FreeBSD virtual pc because svn needed them.
/usr/lib/libgssapi.so.10
/usr/lib/libheimntlm.so.10
/usr/lib/libkrb5.so.10
/usr/lib/libhx509.so.10
/usr/lib/libasn1.so.10
/usr/lib/libroken.so.10

The svn command downloaded all files from that link. Now have to figure out what to do next.

jimp

You can't compile on the firewall - having that code on the firewall doesn't do you any good. You would need to download that to a local FreeBSD installation or VM and compile there, and move the resulting files over. (But even then it may not do what you expect…)

bartgrefte

Ow okay.

Downloaded sourcefiles in virtual pc with FreeBSD 8.2, now trying to compile it, but no luck so far.
Whole bunch of errors when running make on each of the *.c files.

I did an upgrade to RC1 this morning, broke my wifi. So did a clean install, started from scratch, running into the error the reason this topic was made for. Then after changing the channel couple of times + reboot I managed to get rid of it.

But now a whole different problem, that I thought a clean install would solve, guess not:

I think something changed between beta 5 feb.4 snapshot and RC1, since this problem showed up after the upgrade, but what?
Also the upgrade did not fix the "stuck beacon"-bug, so that is still in there as well. Although it is no longer a pain in the a** at the moment.

nothing wireless related has changed in months. These driver issues come and go for some people for unknown reasons. We don't write, maintain or have any control of wireless drivers which is where these issues are, these things need to be reported upstream.

bartgrefte

Hmm…

Well, I managed to compile a newer version of the driver using the source, but now I need to figure out how to get pfSense to (try to) use that one instead of the one already in the kernel. Google explained how to disable and load drivers, but not how to "override" one already in the kernel without having to rebuild that.

bartgrefte

According to someone on the FreeBSD forum the only way to use the new driver is to completely rebuild/recompile the kernel.

Already found this: http://devwiki.pfsense.org/DevelopersBootStrapAndDevIso , but what if I only want the kernel? Any howto's on that?
Someone already asked that but did not get response: http://forum.pfsense.org/index.php/topic,26188.msg163743.html#msg163743
