That looks very interesting
Actually I would suggest going up even higher? At low signal levels I
find (outside of wide open spaces) that the levels are likely to
fluctuate quite a lot. At higher levels the additional signal level
makes little difference.
The only exception might be for very strong signals where you can find
that newer cards seem to drop into a much higher speed mode when they
have very strong signal...
Thanks for the hint. Jouni - what kind of patch would you accept around
this? Any thoughts on the shape of the curve here?
