Bug 548103

Did you set your system time using system-config-date?

I did not myself do so, no. I just did an install (with F11, then updated to f12).

I also see in dmesg that the driver is using the world domain.  I have not specifically used system-config-date to change the time.  This is a fresh install of F12.

Please post your complete dmesg output -- everything starts with the world domain, most things get updated by udev and/or the driver later.

Also, run "setregdomain" and post the difference in dmesg output.

Forgot that `dmesg` has more information than /var/log/dmesg.  Attaching `dmesg` output.  Looks like cfg80211 does finally set domain to US.

dmesg outpyt

Ok. Attaching dmesg output. The difference between the two after I ran setregdomain was:

shillman dmesg output

Suzanne, please attach the contents of /etc/sysconfig/regdomain and
/etc/sysconfig/clock (or note it if one or both do not exist).

contents of /etc/sysconfig/clock

FWIW, /etc/sysconfig/regdomain does not exist.

Well, I'm not sure what is happening.  It looks like /etc/sysconfig/clock has what is needed and running setregdomain manually seems to work for you.  Does 'modprobe -r iwlagn ; modprobe iwlagn' produce fresh CRDA-related output in dmesg for you?

Diffing dmesg and dmesg after the modprobe gives:

Alright, just for completeness please confirm that
/lib/udev/rules.d/85-regulatory.rules looks like this:

# Runs CRDA for kernel wireless regulatory events.
# For more information see:
# http://wireless.kernel.org/en/developers/Regulatory/CRDA

SUBSYSTEM=="ieee80211", ACTION=="add", RUN+="/sbin/setregdomain"

KERNEL=="regulatory*", ACTION=="change", SUBSYSTEM=="platform", RUN+="/sbin//crda"

It looks like the first of those rules isn't getting run for some reason...

OK, looks like it _is_ getting run, but setregdomain is silently failing due to not being able to find iw in its path.  I suspect this may have been broken for a while (i.e. since I moved iw from /usr/bin to /sbin).

Unfortunately, it looks like Fedora CVS is still not cooperating.  I'll get to this shortly after it becomes usable again.  In the meantime, you can either deal with the constrained set of wireless settings, call setregdomain manually, or hack /sbin/setregdomain to change "iw" to "/sbin/iw".

Thanks!

That file is as you put it above, although I suspect you knew this already.

And since this was being tested as part of trying to write testing for firmware in 5.5, I'll just keep working on that test plan and those cases in the meantime. :)

Hey, I'm glad to have the bug report.  But FWIW, the udev stuff isn't in rhel5.5. :-)  The only method there for the _user_ (i.e. not the driver and not the AP) to specify a regdomain is to use the ieee80211_regdom option to the cfg80211 module -- FYI!
