Actually, the 'unpredictable' results are expected.
WiFi runs on the 2.4 gHz band, which was allocated for Microwave Ovens,
in part because no radio designers wanted to use 2.4 gHz.
Prior to microwave ovens, designers stayed away because the 2.4 gHz
radio signals interacted strongly with the water molecules in air,
plants, people, etc. The RadarRange designers picked it because the
purpose of a microwave oven is to excite the water molecules.
So when the RadarRange folks wanted that band, the communications
engineers said "take it, I don't want it"
So it is unregulated world wide, since water molecules are the same size
all over the planet, and maybe galaxy.
Now, we have WiFi, bluetooth, ZigBee and other radios all trying to play
in the same space. And if you move a big house plant around,
or a big roomate, the reception is impacted.
