Had XBox S and new Samsung UHD 65 connected via 5GHz and had worked fine until a month ago. My Samsung Note5 gets an "authentication error" and fails to connect as well. The R9000 has the latest firmware and has been rebooted several times.

Try to factory reset the router and see if that will help. Resetting will wipe out all the settings of the router, so you will need reconfigure it after. You may want to use backup and restore feature for easy reconfiguration.

R9000 5GHz visible but cannot connect. 2.6 band is fine

Have you tried changing the wireless channel?

Will you experience the problem if you downgrade the firmware?

  I don't know what/how "changing wireless channel" means.
  
  I had problem before I installed latest firmware.

  So I figured out how to change the channel-no luck. None of my various devices will connect to the VISIBLE 5GHz band.
