You should be able to use two of these to increase signal over different parts of the house. You will have to wire them together though on their switch ports with a crossover cable. Configure them with two different channels on the wireless side and of course set up the same SSIDs and WEP keys. I am unsure about the DHCP though. You may have to set these for different dhcp ranges, or disable one of the devices from vending IPs, and definetely set one for a different mangement IP. Static IPs, may work a little better here if you plan to roam. The laptop wireless card will typically choose to associate with the strongest signal if not, you could force them to one channel or the other.
