Note that I only do private consulting for a fee. You should send everything
through the wireless ML, which I have added to this reply.
The newest version, i.e. 3.1, will have an improved driver. One with even more
improvements will be in the bleeding-edge compat-wireless package. It is
essentially the one for 3.2. Yes, rtl8192se is being improved regularly. All the
improvements in the 08/16/2011 driver are in compat-wireless.
The number of "bars" in the NM applet are hardly a good measure of signal
strength, but the driver does report a better value. I do not have an
environment where I can test roaming.
