Reflection occurs when your station receiving its AP signal from more than 1 line !!!

when your Fresnel zone is not really clear you AP signal reflects from near obstacles to your client , then your link could be very unstable , sometimes you get 100 Mbps(feeding from real signal) suddenly drop to 10 Mbps(station feeding from reflected signal).

** Fresnel zone is not Line of Sight , may be you have complete LOS but your Fresnel zone is not really clear.

here is a good explanation :

Reflections are generally a indoor issue rather than signal reception issue outdoors?
There is several easily identifiable items outdoor which can cause reflections such as a nearby metal building or perhaps the worst case is where a link is over the sea and tides cause havoc?
