I’m trying to mirror my phone to the television via wifi.With apps alone it fails. l’ve tried every app. What about a device?

I tried Chromecast but it doesn’t mirror also same with firestick.I’m trying to buy device that can do it via Wi-Fi. I’m wondering is this dependent on the router bandwidth? Or can this be achieved with a piece of hardware?

tv Sony Bravia can’t remember the model but the manual is no help. it has casting capabilities but it times out.

Phone s23 ultra

wifi Verizon home Internet with all in one router.

You guys think it’s a router issue or a hardware issue?
