Not sure if it's appropriate to say here.. but when I was installing, there was non-free kernel in my machine. And that's why my wifi was working.
My machine is Lenovo's b50-80, which isn't on the site. > https://h-node.org/notebooks/catalogue/en/1/1/undef/undef/undef/undef/compatibility/undef/undef/undef?search_string=Lenovo+B50-80&submit=Search I've just tried again the same ISO, and chose "wired". It works right away this time. I think it was just a tiny hiccup last time. Should have tried more times then.. sorry about that!
