My brother lives in an old house with thick walls and had difficulty with wireless too. He solved his problem by running a wire to each level on the house and connecting a wireless router in each level to serve as access points. He choose this solution over using repeaters because each repeater in the path reduces the effective bandwidth by 50%.
Only the router with the WAN port connected to the Internet was configured as a gateway. The other routers were configured as access points (he could have brought wireless access points but wireless routers usually cost less because of higher volume of sale).
All routers were assigned a fixed IP address in the same subnet. Extended options such as firewall, and DHCP, QoS, etcetera were disabled on the routers configured as access points.
Finally, he used the same SSID and frequency on all routers to provide seamless roaming throughout the house for laptops.
