Not worth the hassle.  

Get the filename and use a web search engine.

I agree with @Leo Laohoo .... why would you want to use such an old ap for home... Might as well look for something that does Wifi 6 or Wifi 6e.  No one here can share files, so a basic internet search might lead you to a repo where you can find it.  That is how others have located files they need.
