I would second the recommendation for trying different locations for the

software running on the PC), that I ended up implement a lost signal
mechanism to let the rover recover. Then one day when sorting out my work
room I moved the tower to the top of my bookcase. Suddenly no "dead spots" !
I played around and basically decided that getting the tower away from the
PC and monitor was a good thing to do.
I would suspect that antenna placement, and possibly considering a different
antenna design, would make a huge difference. Look in some radio books for
things like Yagi designs. Give you much more range, but also make the antenna
very directional. I use a lot of radio communications for industrial work, and
things that can be 'non obvious', are interference sources, things _behind_
the antenna can have a suprising effect, placement etc.. The actual design of
the antenna has a massive effect, but then you start looking at things beyond
the scope of simple 'movement' :-)
