Why do some wireless routers have two antennae while others only have
one? Is this just a fashion statement or is there some advantage in

Stupid answer?

These devices need to transmit and receive at the same time. Seperate
aerials should work better with less crosstalk between the
transmitted signal and the received signal which is at a lot lower level.
Devices with a single aerial in theory at least, should not be as good as
a twin aerial device.
