Screen mirror wont work on multiple devises

AC3000 model R7900P.   Recently tried to us screen mirroring on my TV.  Did not work, tried other TV same result.  Updated all software on TV's and phone,  Also updated router firmware.  Still no success. Reviewed same network on all devises and tried again.  No success. Reset router to factory default and TV's to factory default...no success.  My phone works in other houses...so not the phone.  Only common connection between all my hardware is the router.  So, something in the past few months has changed.  I could screen mirror to these TV's a few months ago and now I cannot.  Guessing this is a software issue within the router.  All other function work fine.  Ideas?

    Something to ask the Mfr about of this screen mirror application or feature about.

    I have failed miserably in my attempts to "cast". A lot seems to depend on how I try to do it.

     

    The process involves the mobile device, the app in question, what you are casting to and last, and probably least, the router.

     

    The only device that you have listed in your message is your router. The rest of your chain is a mystery.

      Casting to two LG smart TV's and to a Sony DVD player with casting option.  Casting from i-phone. Does not work in my house with the noted router.  I-phone works to other devices at other homes (Hisense TV's).  Used to work on all devices noted here but stopped working sometime in the past two months.  If I could get it to work on one of these devices I would say it is not the router.  But for all of them to have the same issue makes me suspect the router.

        Anything that you can think of that has changed? Stuff like that isn't usually a case of spontaneous combustion.

        Sounds right to me. Anything charged there? Got an old settings backup you could restore?
