We have continued to have problems with our wireless network. Our reception was pretty bad in our living room. It probably didn't help that out Airport Express was behind the metal boxes of electro-magnatism of our A/V equipment. So my goal was to move the base station somewhere where there wouldn't be interference, but also out of reach of the kids. Unfortunately, those places weren't near an ethernet drop.
So I am trying WDS again, with the base station above the kitchen counter. Hopefully this will improve the signal strength downstairs.
