I have a fairly unique situation in my home. I've got my WRT54G in the middle of my second floor. I'm going to add several computers in my basement and maybe use another WRT54G as a bridge there. What I'm looking for is some advice on what the ideal antennas are for both the second floor and basement. I was thinking of adding an omni-directional antenna to the basement wrt and leaving the normal wrt antennas on the wrt on the second floor. Any advice?
