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.
