You could add a simple reflector to the router, and in your example,
another to the client antenna. If you get some signal at the PCs now,
this could give you substantial boost. Omni antennas are not the best for
point to point communications. A reflector is somewhat directional, but
broad enough for me to use throughout my house.

http://www.freeantennas.com EZ-12, printed on photo paper for thick stock,
with aluminum foil glued to the sail, provides a substantial boost in
signal. http://www.rahul.net/dold/clarence/EZ12-windsurfer.jpg

the reflector is not only 13dB stronger, it's more stable.

If you want to experiment more with the bare omni antennas, remember that
the pattern is shaped like a donut on low gain omnis, increasingly flat on
higher gain omnis, becoming like a pizza rather than a donut. In either
case, the beam is off the broad side, not the point, of the antenna. You
want the router and client antennas parallel to each other.
