Comment 58 for bug 1320070

The same behaviour on my Lenovo M30-70 with rtl8723be wifi.
I am using the current beta of Ubuntu 15.04 with 3.19.0-14-generic and wifi is still losing connection.

The workaround from #56 is ok but sometimes it is frustrating.
I also tried #48 and "options rtl8723be fwlps=0" entry in /etc/modprobe.d/rtl8723be.conf but no change.
