You did not tell the reason. IMHO in English, "can't" can mean it works, but you won't do it.

I do not understand this piece. If the nonfree iwlwifi firmware is needed then does Ubuntu still include it ? What about 'only libre' then ?
OTOH if the firmware is not needed, why should you install it.
By the way, did you at some point (temporarily) switch off wifi in the BIOS ? Then, a booting linux kernel can't see it at all and if that was an installation then maybe the proper drivers don't get installed. Just an idea.
