ostin powerin avajaistarjouksesta äidilleni uuden HP:n läppärin. Koneella ei tehdä muuta kuin netti, posti ja pasianssi joten tämäkin riittää.
Asentaessani ubuntu 16.04:sta ihmettelin miksei langaton verkko ei näy, sain kuitenkin langallisena toimimaan. Asennuksen jälkeen langaton löytyi. Itselläni kaikki näytti toimivan ok. Vietyäni koneen äidilleni huomasin ongelmia langattoman verkon kanssa, ensin ei meinannut yhdistää, kun yhdisti niin yhteys alkoi pätkiä.
Koneessa näyttää olevan Realtechin kortti jolla on muillakin on ollut ongelmia.

Yritin korjata
