Wifi and bluetooth button wont turn on how do I fix this

Yesterday morning my tablet wifi turned on automatically & connected to the internet without problem. By late afternoon, I tried to open my web browser and it said no internet connection. I cked the wifi to make sure it was on, to find it was off. When I tried turning it back on, the button remained grayed, and then went back to the off position. I tried the same thing with the bluetooth button, with the same results. I did a hard reset, wipe cache, and a factory reset with no success. Ive seen others have had the same issue with the lollipop OS upgrade as I am having now. Has there been a fix available that will work other than flashing it back to the original kit kat OS?
