« kdy: 07. 01. 2015, 23:41:05 »
AHOJ
nainstaloval jsem ubuntu 14.04LTS a wifi se nezobrazuje vubec. Mel jsem ubuntu na stejnem pocitaci (DELL Inspiron 1545) i pred tim a nebyl problem.

Nevim jak to rozbehnout, ptz kdyz otevru settings-network, moc moznosti co delat se tam nenabizi.

Dik za radu ZKN

Otevri terminal, pust sudo bash na ziskani roota. Co vypisuji prikazy iwconfig, ifconfog, lspci, lsmod? Casto wifi nejde, protoze neni nainstalovany prislusny firmware pro wifinu. Tusim, ze se typicky jedna o balicek linux-firmware.

Bohužiaľ ide o kartu Broadcom:
Kód: [Vybrat]
0c:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)
pre ňu musíš pridať špeciálny balíček napríklad podľa https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx
