Yes.  But it doesn't mean that the driver for your card or the kernel's
802.11 stack are bug-free.  It's likely that the Gentoo Live thing and
the just-installed (and updated) OS have different kernel versions (and
thus different driver versions).  You could try downgrading your kernel
to the same version that is on the Live thing.
