PS4 plug in controller nothing happens

Hey guys I have a PS4 original and I’m having an issue… I turn the system on and it tells me to plug in the controller via USB cable. I do so the yellow charging light comes on for the controller then I press the ps button. The light on the controller flashes blue for about 15 seconds and then turns back yellow. I can use the controller in the safe mode settings tho. It seems to me the controller isn’t syncing up to the ps4. Any advice is greatly appreciated

Usually that type of problem is caused by a faulty WiFi/BT module.
