Hi Larry,
i've tryed with kernel "3.8.5-201.fc18" two device wireless Realtek usb:
no one of this work corretcly with kernel 3.8.5-201 Fedora or 3.8.6
vanilla (kernel.org)
eitherdo not connect to the wifi router, but they both see the wireless
networks
one of this, on kernel 3.2.x and 3.0. 8 vanilla (kernel.org) using the
Realtek driver work correctly:

i will try the wireless-testing git tree and then I'll let you know,
for download the kernel source from the wireless-testing git tree is it
correct this procedure?
|git clone
|git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-testing.git
many thanks!
