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
