NUCissani on Intelin wlan-kortti, joka menee "tukkoon" silloin tällöin. Samaa vikaa tuntuu olevan monessa muussakin distrossa. Ongelma on se, etten ymmärrä, mitä koneeseen pitäisi ladata/pätsätä, että wifi toimisi OK.
Tässä lienee vika korjattu, mutta allekirjoittanut toivoo käännöstä "naisen logiikalle"
