Looks a lot like my driver experience with older kernels, I had to use
the external driver in the rare event that I needed wireless to work.
The in tree driver works peachy these days (needed it recently, was
pleasantly surprised when it _just worked_, not even a hiccup), so
somebody cared, gave at least the 10ec:8181 bits some serious love.
