  One being a repeater for the other wouldn't work if your wireless
isn't making it through the floor to begin with. 
  Run a cable upstairs (if you haven't already) then use both APs with
identical SSIDs & key (and method, WEP, WPA, etc) but definitely
different channels. Channels also overlap, so pick channels that are a
few apart. You actually need to be 5 channels apart to be completely
overlap free.


A few instructive pics about the channel distribution.
