Hamed,

 From your report, the problem occurred between kernel 4.9.13 and 4.9.14. 
Unfortunately, there were no changes in the kernel.org repos that would affect 
the RTL8821AE. It is possible that Fedora made some change that is not present 
at kernel.org, but I find that unlikely.

Did anything else on your system change? In addition, you should post an excerpt 
of the dmesg log that shows the nature of the disconnect.
