120 on the router is very doable. It is at one end of the house. The
antenna on the router is a stub, presumed 360. Where does one get a
directional? I could also do a directional on the Myth box.
Put a parabolic reflector on the stub antenna. You can build one out
of cardboard and aluminum foil. Quote from archived kplug

After sending this message, I went to look at the original web site,
and found that the template for cutting the cardboard had disappeared.
So I found it using the Wayback machine.
For a while, it will be at
< ftp://ftp.mpl.ucsd.edu/pub/cdl/windsurfer.ps.gz >.
Two polar directivity plots and templates for the two pieces
< and some instructions.
Still there at "my" ftp site.
