Hi,
I have a bcm4306 card in my desktop machine. I am running a build of 2=
=2E6.25-rc9. I have tried fiddling with the network build options and =
no matter what I select, my network performance is absolutely terrible =
(between 0 - 24KBps). Connections take around 10-20 seconds to establi=
sh. I have a cable modem, and usually see nearly instantaneous connect=
ions and between 65-600KBps throughput. I just tried downloading somet=
hing and am seeing this: 223B/s. Everything is intermittent and and o=
ften times out.
I am attempting to collect a log for you to analyze. However, I am run=
ning into some snags.
1) The latest firmware, which is called for in the latest kernel code,=
won't work with my Ubuntu 8.10 kernel (2.6.24-16-386). I got the late=
st iw git code downloaded, but it won't build for me:
# make

interface.c: In function =91get_if_type=92:

I built with a bunch of network and wireless debugging options enabled =
and am seeing this is my kernel log:

You need a newer copy of nl80211.h or revert back to an older revision
of iw before the mesh code was added.

No, you can just get it from gitweb too :) But other than that,
probably. Or a compat tarball would work.

The empty one is created when you configure, because there's a kconfig
symbol for nl80211. I'm not sure why it is empty, it should have
"#define CONFIG_NL80211 1" or so in it. The ./usr one is a copy of
the ./include one, that's done by headers_install (IIRC), the
net/wireless/nl80211.h one is for some local stuff in that dir.

Am I required to get the linux-wireless git kernel tree in order to
get the newer nl80211.h?
I checked in the 2.6.25-rc9 tree and was surprised to find four copies
of nl80211.h:
0 2008-04-14 23:48 ./include/config/nl80211.h
10074 2008-04-11 16:32 ./include/linux/nl80211.h
510 2008-04-11 16:32 ./net/wireless/nl80211.h
10074 2008-04-15 05:50 ./usr/include/linux/nl80211.h
It seems interesting that two copies have the same byte count and that
one of the files is empty. What's up with that?
Thanks,
Miles

You can take the latest compat-wireless, as suggested on the iw page:

Only files in "include" are for external use. Files under
"include/config" indicate kernel configuration. You don't need that.
That leaves include/linux/nl80211.h
Another approach. iw sources include linux/nl80211.h, and defconfig
refers to "include". That gives the same answer.

Which revision of the BCM4306 do you have? Which driver (b43,
b43legacy, or bcm43xx) are you running?
Based on comment 1) above, I think you are using b43, but why should I
have to guess?
