Tesla Motors Club

I am not able to receive updates. It involves my connection to my router. I show 3 bars reception. When I search ,my router shows up. If I go to the router and enter the password it connects. On the line that shows my router there is a dim icon of a lock along with an icon I suppose is an antenna.
It shows that I have update 2020.36.11 available for update. The update at the top of the screen turns red when I click it.
I had successfully updated a couple months ago.
Another question ...how do I get back to this post and your answers?
