(solved 2017) Ps4 controller disconnects, lags randomly, bluetooth/wifi issue or bad update?

Hello everyone i'm new here and to discuss an issue i recently came across with my ps4 controller having connectivity issues, after updating i thought

it was a bug in the update but turns out its not, how i know? because i have another ps4 that i can test the controller itself both Consoles running the

 4.07 software, with that being said i have tried reinstalling software (4.07) , initialize, resetting the controller  all that stuff and nothing seems to work

then i noticed standing directly in front the system works perfectly but back sitting on my couch it starts acting up so about the issues i had:

1. controller would randomly shut itself off sometimes a few times in a minute.
2. The response of pressing buttons are slow sometimes takes a few seconds for it to get caught up. 

Now the fix:

1. Since the Ps4 uses the same antenna for both the Bluetooth and Wifi connectivity i figured i would replace to see if it fixes the issue AND IT DID!!!

  SO IF YOUR'E HAVING PROBLEMS LIKE I EXPLAINED ABOVE TRY REPLACING THE WIFI/BLUETOOTH ANTENNA ITS FAIRLY EASY TO REPLACE AND CHEAP CAN BE FOUND ON EBAY FOR ABOUT $8 BUCKS HOPE THIS HELPS SOMEONE OUT THERE.
