I see the same bug on my Lenovo G50-45. Unloading and reloading the module as in #56 gets me back online. However, its not a permanent solution as it will again drop intermittently.
Looking at the module parameters, it seems msi is 0 by default.

How can I help (by testing) to get this fixed? Is there a way for me to look at logs or some module/device state to see if msi or power save triggered the problem?

Kernel info:
3.16.0-34-generic #45~14.04.1-Ubuntu SMP
According to http:// askubuntu. com/questions/ 526214/ how-to- set-parameters- for-realtek- wifi-rtl8723 the culprit could be powersave.
Looking at the module parameters, it seems msi is 0 by default.
