One 7101, multiple locations, multiple WIFI routers

Hi,

I have a 7101 outdoor router, which is now connected to a 5101. That setup works great. However, the plot of land that I live has two house, which are some 10 meters apart. I'd like to know what additional hardware I can buy to have the following:

• In one house, the 7101 will be on the roof
• In both houses, I'd like (not necessarily the 5101 included) a WIFI router (or simply two access points) attached to the 7101 (albeit through a switch).

Does somebody have any experience with it? And which switch/routers are you using for it?

From one house to the other I could draw a UTP cable, but if someone has a setup or recommendation to only have wireless routers instead, I'd be happy too.

Regards,

Arjen.
