You do. You need to know how to set it up and then use it.

No you don't need "internet knowledge" for iPlayer, don't be so melodramatic.
It's just basically an app.  If you can use an app on a phone you can use an app on the TV/Firestick/<insert device of choice here> where there is no need know anything about the internet.  It just needs a connection.

Well it depends on what you mean my Internet knowledge. If knowing what to do if your router stops working is Internet knowledge then yes you do need it.

My 82 year old mum can’t use iPlayer on her smart TV. I’ve tried and tried but she just doesn’t understand that up and down arrows moves round a screen.

For most of us used to cursors and using a mouse it’s obvious, but she is someone who is terrified of pressing any button she doesn’t know 100% what it will do before she presses it. She would NEVER just try a button to see what it does like most of us would do.

So as things stand she can press 1 for BBC One, 2 for BBC Two and 3 for Granada (as she still calls it).

She will not attempt to use anything more complicated than that.
