Roku updated and have lost all my Antenna channels.

It claims I can see local channels through Roku live.  They are all news or not the real local channels.  I am in a large metropolitan area and my antenna use to work. I have searched for live tv and followed many steps you advise only to not see the final step.  I have had Roku before and not had this issue.  
Live tv channel guide only shows me stations that are not local and not CBS, NBC, nor ABC.
