WI-FI adapter for Pure OS

Greetings forum! I am posting my query to this thread - even thought it is two years old - as it addresses specific modifications that can be made for compatibility.

For over a year now, I have wanted to migrate to Pure OS, but I’m pretty sure my hardware, on a Thinkpad L540, won’t support it. I checked H-Node - after finding that the Pure OS Debian link to hardware requirements (via OS Pure’s wiki) was not as complete.

I bookmarked Technoethical’s N150 Mini a year ago (when I last did serious research into this problem), but I don’t know:

  1. If this will be the ‘fix’ I need to make my hardware compatible with free software;
  2. [Unrelated to this thread!] whether sound card/video cards won’t work without non-free blobs - which I would likely not know how to find/install.
