Public bug reported:

This problem occurs on my new HP 15-AF014AU notebook. I installed 14.04
several weeks ago, and noticed the WiFi dropping out. I moved to
14.10, which seemed initially to fix it, but after a few hours it dropped out
there too. I moved to 15.04, and the problem persisted.

My wifi card is a Realtek RTL8723BE, and the driver for that card may be
the source of the problem.

 I found a work-around described here:
https://zach-adams.com/2014/10/wifi-dropping-xubuntu-14-04-rtl8723be-fix/
which seems to be working.

Also I can get it going again by disconnecting then reconnecting via the "hidden network" menu
option. This sometimes takes two or more attempts.

A proposed fix given on one discussion group is to add a /etc/modprobe.d/rtl8723be.conf file containing
"options rtl8723be fwlps=0", then restart. That seems to have stopped the periodic
dropping out, but I still need to do the hidden-network connect when coming
out of suspend.
