Wifi aktiveerimine Ubuntu 14.04 server masinas

Pole eriline süsteemis nokerdaja aga üritan saada käima oma isikliku serverit mis töötaks üle wifi ühenduse, et see kast pärast rõdule visata suhisema ja kaabel sabast ära.

Tarkvarana siis jookseb Ubuntu 14.04 server ja süsteemi seadistan üle ssh ja webmini. Hetkel on server ühendatud kaabelnetiga. Wifi täiesti toimetas ennem kui oli peal graafiline distro.

Googeldades leidsin mingeid juhendeid ja klopsisin kokku all oleva koodi ehk siis hetkel on masina /etc/network/interfaces faili sisu järgmine --> rea # WIFI ja alloleva kõik olen ise lisanud, ülemine osa on originaal.

Kood:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface

# The primary network interface
auto eth0

# WIFI

käsu ifup -v wlan0 peale sain järgmise vastuse

Kood:

ja ifconfig näitab sellist infot
