Koneessa on jokin Mediatekin wifi-piiri, jolle ei ole ajuria suoraan kernelissä. Katso laitteen tarkemmat tunnistetiedot lspcillä:

jep, on mulla usb-wifi, mennä sillä jonku aikaa

Minkälaisen koneen ostit? Ilmeisesti kuitenkin läppäri?

Sama Mediatekin piiri näyttää olevan myös joissain Asus Vivobookeissa. Hankala tapaus, ja kannattaa melkeinpä palauttaa kone, jos on tulossa Linux-käyttöön.
