wireless is strange

[antonio montagnani]

I am connected to a Picostation as repeater: sometimes laptop is 
disconnected and I see a question mark on the top line wireless icon, 
and it connects again only if I switch of and then on the wirelss...
in F20 it never happened.Smarthphone is always connected

Any idea???
