I know from the E-mail you sent to me privately that you are new to this 
process, thus I am going to give you some pointers. It is important for you to 
give your kernel version. Yes, for devoted Fedora users, saying that you are 
using F27 might be sufficient; however, I am not one of them. You should always 
supply the output of the command 'uname -r'.

On the RTL8723BE, "Init MAC failed" is not the dmesg that is expected from 
either the HP ant_sel problem, or a power-save problem. Incidentally, although 
there are many "fixes" that require modifying the XXps options, the underlying 
cause of that issue was fixed almost one year ago.

The main software component that might be wrong is the firmware. Please find the 
name of the firmware file that is being loaded from the dmesg output. It will be 
rtlwifi/... Once you locate that name, run the command

md5sum /lib/firmware/rtlwifi/xxx

Substitute the actual name for the xxx. Post the output of the md5sum.
