As my mail bot told you, I don't do private consulting of the type you wanted.

The firmware is found in the linux-firmware git repo. There is no separate 
download site for it. Ubuntu needs to update whatever package provides the 
firmware to provide the latest firmware files. You should pass that info on to them.

When you are having the cold start problem, are scans working? In other words, 
does the command 'sudo /usr/sbin/iwlist scan' return any APs?

Is the wifi blocked? What is the output of '/usr/sbin/rfkill list'?

Finally, what does the log shown by the output of dmesg show? I will not need 
all of it - only the part after rtl8723ae starts.

I am not a user of Ubuntu and that distro might place iwlist and rfkill in 
different places than on my system. In addition, rfkill might not be installed. 
If not, then use the package loader to install it.
