Clicking the WiFi or Bluetooth buttons on your newly flushed/reset phone,
and the button keeps turning-back to disabled-state?
-before you’ll snap your tablet in half
in a pure-rage against the machines, try the following solution…
Root your device, and grab yourself a root-access capable file-browser,
I’m using Xplore File-Manager (the first time you should set its settings to have full root access + automatic r/w mount in-case needed), btw. setting a file or a folder’s permissions is easily-done by a long-pressing the file (or folder) and selecting the “permissions” entry, from the pop-up menu.
change the permissions for the following folders to

Still no luck?

.system.bcm_supplicant(if exist) to

Look for files with

- a reboot is required.
Consider using a permissive-kernel, since some files
may be reverted to their previous unmodified state,
as an enforced-security, this is common in Samsung devices with Android ver5.1+
Installing a permissive-kernel will usually solve it.
Some quirky Android devices may have those files somewhere else,
so after you follow the generic instructions above,
use the Xplore File-Manager find-functionality with
*bcm_sup*) from the
/ (the root or “top-most” of all folders..), just to be sure…
if you’ve follows all the instructions above,
and rebooted your device, you should have BOTH your WiFi and Bluetooth working properly now.
*If you CAN actually enable WiFi and root-access is an issue for you,
You can try to cure a kept-disconnecting network by hard-stopping the WiFi’s power-saving mode.
It can be done using the WiFi menu, or more easily- through a “secret-code” typed into the phone dial-pad: “dial”
*#0011# and on the service-mode screen press the left-menu button, quickly choose “WiFi” and click the WiFi power-save mode button to disable it.
Exit the menu, turn ON your WiFi discard/forget all of your remembered networks, turn your WiFi OFF and ON again and connect to your network, entering its details, passwords etc..
Here is *my* prop file (64bit Note5, so don’t use it as-is)
you don’t have to do anything with it,
and usually if you install a permissive kernel, it will
make sure there is a prop file in your device with those values after each reboot,
