Well, it "makes a difference" in the sense that the warning goes away.
But it doesn't make things work. In fact, it might be making things
worse.

I will try Johannes' suggestion on that machine to see if it makes a
difference, but somebody who knows the rtlwifi rate control code
should take a double- or triple-look at this.
Please? Some googling shows that
