I have Windows* 8.1 but I just verified the KB2919355 is not installed in this system, if that is what you meant.
I may try to install it; however, I am not sure I will be able to fully replicate your issue.
Do you know if your operating system is 32 or 64 bit?
Were those older drivers (v16.5) provided by the system manufacturer?
I am thinking that is probably a conflict with the “Wireless Radio Switch Driver”, did you try uninstalling it first?
