Comment 21 for bug 1454843

I can confirm that the solution proposed on #14 (or, as just sayd by @Vincenzo, maybe rather a workaround) works also on 16.04.
With this ubuntu version I added "options rtl8723be ips=0 swlps=0 fwlps=0" in my /etc/modprobe.d/rtl8723be.conf to be sure to disable all module power save controls (with 14.04 I didn't include swlps and I remembered that one time the bug happened).
