This patch adds support for new firmware.
Old firmware is still supported until July 2008.
To get new firmware, go to
ftp://ftp.linksys.com/opensourcecode/wrt150nv11/1.51.3/
and download the tarball. We don't have a smaller tarball, yet.
That will be fixed later.
You can extract firmware out of the "wl_ap.o" file contained
in this tarball using latest fwcutter. You must pass the option
--unsupported to fwcutter.
Fwcutter-010 with official support for a new firmware image will
be released soon.

I have finally found some time and hardware to test it, but the tarball
is overwhelming at its 186M. And the worst thing, the server
disconnected after 30M and appears to be down right now. P.S. It's up,
ETA is 48 minutes.
There were two files there. I hope either is fine. I'm trying to
download WRT150NV11_v1.51.3_ETSI.tgz
Cannot we petition Linksys to put wl_ap.o outside the tarball? Or maybe
Broadcom could do it?
Even a zip file would be better. It's possible to cut a part of the zip
file and uncompress it with gzip.
It's really a travesty of open source. The file is "available", but you
have do download 186M of useless (for me at least) mips compilers and
other stuff. And I have a relatively good connection.

Do you know that the Subversion repository of fwcutter has no files at
all? I mean svn://svn.berlios.de/bcm43xx/trunk
Yes, I will try --unsupported, with version 009.

Actually, I think I will change that _now_.
I'll simply put the stuff on my server. berlios is just too annoying.
I'll put the new URLs on the b43 linuxwireless.org page.

We already have a better file on an openwrt server that will be the
officially supported one soon.
I just have to create a new fwcutter tarball and link from linuxwireless.org
to it. I already added support for the file to fwcutter git.
See Stefano's comment below.

Yep, the berlios stuff is dropped completely, except the download
section for the fwcutter tarballs. But that may also change in future.
We will announce that on linuxwireless.org.

Please do it, if you feel so.

Good luck. ;) The only long-term lasting solution I see is to put more
effort on an open firmware. The instruction set has been figured out, we
just lack people and time there.

fwcutter development now happens here:
http://bu3sch.de/gitweb?p=b43-tools.git;a=summary
Maybe we should add this along with git URLs on linuxwireless.org.
