Lifehacker had a post from freeantennas.com on how to boost your wireless signal using household products.  Some reported gains of 100%, but others found gains of only 5%.  But of more interest is a link to another post that shows you how to change your router from a $60 to a $600 one by hacking the firmware.  Might be worth a try (at your own risk).
