Ubuntu tietokoneissa / Wubin kanssa ongelma verkkoyhteyksissä
« : 31.08.12 - klo:13.56 »
Jatkanpa tähän oman ongelmani kanssa. Hain kaupasta uuden 15 tuuman läppärin. Sinä oli Win 7 home. Asensin wubilla 12.04:n. Verkko toimii Win-puolella, mutta ei Ubuntussa. Kaapeliyhteyttä ei löydy ollenkaan. Langaton käynnistyy, mutta lupsahtaa aina muutaman sekunnin kuluttua pois. Vain mokkulanetti toimii. Kysymykseni kuuluu, onko Win 7 keksinyt jonkun jipon, jolla se pystyy häiritsemään. Vai onko kyse Lenovon ominaisuudesta.
Tuossa on vähän legendaa, jos joku haluaa vilkaista asiaa syvemmältä. Minun konstini loppuivat.
