Sure try an external aerial or at a pinch set the router (with its integrated aerial) outside to test how it goes first.
It is also possible to increase the directivity of the aerial/s by using a reflector of some sort, a simple parabolic reflector which has the effect of increasing the gain in the desired direction of pickup. One of the RF guys here could better comment here, but I once made one for in home use and it increased the signal strength of the 2.4GHz signal in the desired direction and created a null /lesser signal behind the reflector. A piece of sheet metal / foil or metal mesh can work if the holes aren't too far apart.
Here's something of the sort just described to try. To keep it simple cut open a coke or beer can and roughly form to the shape suggested. Very easy- just sit the shaped parabolic cylinder on the desk behind the antenna/e and have it fire in the direction you want the strongest signal directed to or received from.

Then of course there's the Cantenna or sometimes Pringle's Can Antenna. I never tried one, but some wireless surfers love them.
