I compiled (as part of kernel 3.2.9) the r8712u module.
Comes up OK but cannot take an essid nor a key.

There are a couple of bugs in 3.2.6+.
I don't think they have been fixed by 3.2.9.
Check dmesg for a "Badfw size" message.
If you see that, the two attached patches will fix that.

Hi Larry,
Thank you for the patches.
Unfortunately, no cigar: <same problem>

I tested your iwconfig statement using kernel 3.3-rc5. It worked.
Then I downloaded a fresh copy of 3.2.9 and built it. It also worked.
I have no idea what is wrong on your system, but it appears not to be
the kernel, but something in your user-space tools.
My tests were done with openSUSE 12.1.

Hi Larry,


I re-installed "wireless-tools.29" (just in case).
Same problems as before (doesn't take essid, nor key), i.e.,
the module doesn't work here.
FWIW, I'll be attaching highlights of the latest tests.


I don't know why on your system (openSUSE) the module/tools work
while on mine (BLFS) they don't.


As opposed to "distributions", a BLFS is a system not installed but
built "by hand", so the owner feels they have more control and know
what's under the hood better.
See: <www.linuxfromscratch.org>
My subject system has been working just fine for years now:
ASUS P5E-VM HDMI, Intel E8400, 3.0 GHz, 4 GB, G35/ICH9R, SATA

Thank you for your help. We'll make it work sooner or later.
