After installing Ubuntu 14.04 64bit I encountered the continuos network hang.
Network manager doesn't seems to change its status, as well as my IP address still remains but OS doesn't ping.
The only solution is to reboot the system and wait for next network hang (I tested that just few commands via ssh lead to the issue).
To fix this I launched the following command and reboot the system:
$ echo "options rtl8723be fwlps=0 ips=0" > /etc/modprobe.d/rtl8723be.conf
