Question about HP quicksync for HP mini 5101

I recently downloaded hp quicksync and was trying to sync files with my other laptop.  I tried to sync files for the whole week by using wifi connection, but is still not successful.  When I opened the quicksync program on both computer, i cannot see the other computer thru "my connected device" and when i was trying to sync, nothing sync between two computers.  Does other use this program and is successful to sync files between computers.
