[Jim Breen <jimbreen@xxxxxxxxx>]

I have this problem too, on my HP 15-AF014AU notebook, running 15.04.

My wifi card is a Realtek RTL8723BE, and that seems to be a common
feature in the problem.

I added a /etc/modprobe.d/rtl8723be.conf file containing
"options rtl8723be fwlps=0", then restarted. That seems to have stopped the periodic
dropping out, but I still need to do the hidden-network connect when coming
out of suspend.
