I'm new in Ubuntu and I have a problem with my Wireless card Broadcom BCM 4312...

I have installed Ubuntu 13.10 Desktop on my netbook with USB, because i haven't got CD/DVD-ROM....Installation looks fine, Ubuntu works fine, too, but I cant connect to the internet by Wi-Fi. I don't know, what should I do with it..:( ... BTW: I can connect to Internet via LAN, but at my home I can't connect by LAN, because we have Internet developer, which banned connecting from other IP....but that's not problem...

Can anyone help me, please? :)

...and I connect there some print screens of PCI list, iwconfig and Installing bcmwl-kernel-source (this language is Slovakian, but it says, that you must insert install CD into media/cdrom, but I haven't got CD-ROM -_-...

enter image description here

Thank you in advance for every answer :)

Use either a wired or bluetooth tethered connection to get wifi temporarily up and running, then run:

$ sudo apt-get update

Then open 'Software and Updates' and select the proprietary Broadcom driver.
